Urolithiasis 2000, Proceedings of the ninth International Symposium on Urolithiasis, Cape Town, South Africa. Successful therapy of hyperuricosuric calcium oxalate nephrolithiasis with potassium citrate. Urine quantity and urinary oxalate focus are most influential on therisk of stone formation, whereas magnesium focus contributes a small quantity to danger. Potential unwanted facet effects embrace hypokalaemia, hypotension, allergy and solar sensitivity, and hypocitraturia (which tends to promote stone formation). Generic advice the concentration of urinary solutes could be manipulated through applicable fluid intake, food regimen, and medical remedy. Fluid intake should be elevated to preserve a urine volume higher than 2 L in 24 hours1 and should take into account occupation and wise and insensible water loss. Calcium and oxalate secretion can be manipulated to various degrees by food regimen alteration. Restriction of dietary oxalate (<100 mg/day) and avoidance of high vitamin C (a precursor of oxalate) consumption might restrict oxalate excretion. Significant or resistant hyperoxaluria could also be as a result of one of many primary hyperoxaluria syndromes. Hypocitraturia Potassium alkali (usually potassium citrate 10�20 mmol twice or thrice a day) chelates calcium and inhibits development of calcium crystals. It is useful for patients with hypocitraturia9,10 however can result in excessive alkalinization of the urine, which can facilitate calcium phosphate stone formation. Hyperuricosuria Hyperuricosuria decreases the solubility of calcium and oxalate, so growing threat of calcium oxalate stone formation. Allopurinol (100�300 mg/day) has been shown to reduce urinary uric acid ranges and stone recurrence in patients with hyperuricosuria who kind calcium stones. Conclusion In conclusion, preventive therapy has been shown to cut back stone recurrence in long-term scientific follow-up.

Randomized double-blind research of potassium citrate in idiopathic hypocitraturic calcium nephrolithiasis. Preminger Introduction to prevention of other non-calcium stones the primary goal of stone preventive therapy is to reduce future recurrences or prevent growth of any existing stones. Non-specific measures as nicely as particularly targeted medical therapy could be utilized to lower future stone-related occasions. This has been potential with the advancements in understanding of the pathophysiology of urinary stone formation, identification of metabolic risk factors, and availability of selective and non-selective strategies to modify these dangers. The objective of prevention for uric acid stones is to elevate the urinary pH with alkaline therapy. For cystine stone formers, prevention is centred at raising urinary pH to increase the solubility of cystine and lowering urine cystine focus. Suppressive antibiotics and acetohydroxamic acid can be utilized to prevent recurrence. The citrate content of assorted drinks has been evaluated to estimate their beneficial impact on stone prevention.

Syndromes
The commonest opposed events reported for mirabegron were hypertension, urinary tract an infection, nasopharyngitis, and constipation. More lately, it has also been investigated in painful bladder syndrome and interstitial cystitis. Commonly, the minimally invasive two-stage technique is utilized to insert the neuromodulator. The foramen with the most effective sensory motor response from S2, three, and four is selected for tined lead implantation (most generally S3). After a interval of therapeutic, an exterior stimulator is used to take a look at the response to the neuromodulation. The use of bilateral sacral neuromodulation is also beneath investigation and some surgeons place bilateral tined leads on the primary procedure; thereafter, a two-channel modulator is linked to both leads. Cautions one ought to apply in a affected person with a neuromodulator embody using excessive frequency monopolar diathermy, extracorporeal shock wave lithotripsy, and radiotherapy over the device. Surgeons also wants to be aware that the system may be positioned within the loin or stomach wall. Problems include an infection, battery failure, lead migration, and loss of efficacy-this can often be resolved with reprogramming the stimulation parameters, or by insertion of a contralateral lead. Multicentre trails have shown statistically important enhancements in frequency episodes, urgency episodes, voided volumes, and high quality of life parameters over placebo. The intended benefits are that patients are given extra autonomy over their situation, an extended battery life, and decreased adaptation of the nervous system to stimulation. OnabotulinumtoxinA is the one preparation, at the time of writing, which has a licence for use. Improvements have been shown in urgency by 53%, frequency by 35%, and incontinence episodes by 68% per day. In addition to this, the maximum cystometric capability has been proven to improve by 58% and mean detrusor pressure to lower by 39%. However, a dose ranging examine has proven 100 iu was sufficient to have a major impact on symptoms, bladder diary parameters, and high quality of life (QoL). Therefore, a extra balanced dose of onabotulinumtoxinA to commence sufferers on could also be 100 iu. In patients who develop voiding problem and raised post-void residue, intermittent self-catheterization might must be instigated. Other adverse events that are reported embrace dry mouth, muscular weakness, impaired imaginative and prescient, and dysphagia. These are all uncommon nonetheless, and are increased when using larger doses of the toxin. Drug interactions embody aminoglycosides, penicillamine, quinine, calcium channel antagonists, and muscle relaxants. The number of injection websites and quantity per injection needs further investigation. It was also feared that injection into the trigone may precipitate ureteric reflux, however in two totally different research this has not been shown to be the case, and in fact the trigone injection group showed larger enhancements. This less invasive process uses a fine needle electrode inserted above the ankle. Other research have shown will increase in most cystometric capability and volume at which first detrusor overactive contraction happens. This patch transmits a transdermal amplitude modulated signal when positioned on the pores and skin over the sacrum. After one week of remedy, 50% of sufferers reported at least 50% discount in urgency incontinence episodes. There are many strategies which embody transcutaneous, percutaneous, and sacral approaches. There is little evidence for its use in this group of sufferers and the approach has not but been standardized. If the resting detrusor strain is high or the bladder capability is severely reduced, then cystoplasty may be utilized to increase capacity. It is due to this fact necessary for a urologist to perceive these and can handle these appropriately. In addition, nocturia may lead to a large reduction in QoL, work productiveness, and will increase the chance of falls and mortality in elderly folks. In patients with nocturia, global polyuria ought to be excluded by way of a frequency quantity chart.

Perirenal fats could be reapproximated over nephrotomy incisions, and external drainage is placed near any nephrotomy incisions. Partial nephrectomy Partial nephrectomy is indicated when stone illness is associated with a localized area of irreversibly poor renal operate. At this point, the renal vein can also be occluded to guarantee a blood-free surgical subject. The kidney is packed with slush with the goal of obtaining a core temperature of 10�C, again as safety from renal ischaemia. Once the kidney has reached core temperature, the capsule is incised longitudinally between the anterior and posterior segments, but prolonged solely to the apical and basilar renal segments. The incision by way of the parenchyma continues in a aircraft along the road of demarcation between the anterior and posterior arterial segments, down in the course of the renal pelvis. The right plane generally runs simply anterior to the posterior row of infundibula and calices. The stone is recognized either by palpation in one of many involved posterior infundibula or calicyes, or by direct visualization. Once the preliminary stone-bearing infundibulocalix is open, a longitudinal infundibulotomy is performed and extended right down to the renal pelvis. Each involved posterior infundibulocalix is similarly opened longitudinally as far as essential to extract any stone and the infundibulotomy is carried down its anterior aspect in the direction of the renal pelvis. Once the pelvic and posterior infundibulocaliceal features of the stone are identified, the anterior and polar parts are exposed, again with sequential longitudinal infundibulotomies. However, these are carried out on the posterior facet of the anterior segmental infundibula, and central features of the polar infundibula. Again, the infundibulotomies should start at every infundibulopelvic junction and extend outward in course of the calix as far as necessary to present enough exposure for stone removing. Once the bulk of the stone is removed, every infundibulocalix is explored to exclude residual fragments. Occasionally, these Nephrectomy Nephrectomy is indicated for stone illness related to a nonfunctioning or poorly functioning kidney (determined with a renal scintigraphy). Conservative management risks morbidity from recurrent urinary tract an infection, pyelonephritis, or sepsis. Laparoscopic and robotic anatrophic nephrolithotomy have also been described with good outcomes. Both of those minimally invasive strategies are less invasive than the normal open strategy.

Thus, the tumour cells would resemble morphologically the epithelia of the fallopian tube, endometrium, or endocervix (1, 8). It has been shown that some high-grade serous carcinomas come up from precursor epithelial lesions in the distal fimbriated finish of the fallopian tube, whereas endometrioid and clear cell carcinomas originate from ovarian endometriosis (8). Serous borderline tumours usually happen in women aged 20� 50 years (average, forty six years). Serous tumours are more commonly bilateral (34%) than mucinous ones (6%) or other types. Serous borderline tumours have one or more cysts lined to varying extents by papillary projections, starting from nice and exuberant to grape-like clusters. These structures show (1) epithelial stratification, (2) reasonable nuclear atypia, and (3) mitotic activity. Common epithelial neoplasms most commonly affect nulliparous ladies and occur least frequently in ladies in whom ovulation has been suppressed. Whereas 862 SeCtIon 12 Gynaecological Oncology Surgical cure is sort of always potential if the serous borderline tumour is confined to the ovaries. Even if it has unfold to the pelvis or stomach, 90% of patients are alive after 5 years. Pathology High-grade serous carcinomas are the commonest ovarian cancers and most patients present with advanced stage disease (approximately 80%). They are predominantly stable masses, often with necrosis and haemorrhage and sometimes show obvious stromal invasion. Mucinous carcinoma Molecular pathogenesis Mucinous ovarian tumours are often heterogeneous. Benign, borderline, non-invasive, and invasive carcinoma components might coexist throughout the identical tumour. Such a morphological continuum means that tumour progression happens from cystadenoma and borderline tumour to non-invasive, microinvasive, and invasive carcinomas. Pathology Mucinous carcinomas are normally massive, unilateral, multilocular cystic plenty containing mucinous fluid. Since benign and malignant parts could coexist inside a single specimen, these tumours ought to be sampled extensively. Mucinous tumours are bilateral in only 5% Malignant epithelial tumours (carcinomas) Carcinomas of the ovary are most common in ladies aged 40�60 years, and are rare beneath the age of 35 years. These subtypes, which account for 98% of ovarian carcinomas, may be reproducibly diagnosed and are inherently completely different ailments, as indicated by differences in epidemiological and genetic danger elements, precursor lesions, patterns of unfold, molecular events throughout oncogenesis, responses to chemotherapy, and outcomes. With progress in course of subtype-specific management of ovarian most cancers, accurate subtype assignment is turning into more and more necessary. Serous carcinomas Molecular pathogenesis Low-grade and high-grade serous carcinomas are basically totally different tumours. The class of mucinous borderline tumour with intraepithelial carcinoma is reserved for tumours that lack architectural features of invasive carcinoma however, focally, present unequivocally malignant cells lining glandular spaces. Mucinous borderline tumours with intraepithelial carcinoma have a very low chance of recurrence (1, 2, 8). Mucinous carcinomas showing expansile or confluent glandular growth appear to have a more beneficial prognosis than mucinous carcinomas with harmful stromal invasion. The mixture of extensive infiltrative stromal invasion, excessive nuclear grade, and tumour rupture must be considered a powerful predictor of recurrence for stage I mucinous carcinomas (1, 2, 8). Pseudomyxoma peritonei is a medical situation of abundant gelatinous or mucinous ascites within the peritoneum, fibrous adhesions, and frequently mucinous tumours involving the ovaries. The appendix can be involved by an analogous mucinous tumour in 60% of the instances and appears regular within the remaining 40%. Current knowledge suggest that in most cases the ovarian tumours are metastases from the appendiceal lesions (1, 2). Up to half of those cancers are bilateral and, at 864 SeCtIon 12 Gynaecological Oncology prognosis, most tumours are either confined to the ovary or within the pelvis (1, 2). Molecular pathogenesis Endometrioid carcinomas are thought to come up by malignant transformation of endometriosis, and never from ovarian surface epithelium. Pathology Although they might be cystic, most endometrioid carcinomas are largely strong with areas of necrosis. Strong knowledge suggest that virtually all of these instances arise independently, although some may be metastases from one or the other. Clear cell carcinoma this enigmatic ovarian cancer is closely related to endometrioid adenocarcinoma, and often happens in association with endometriosis.

Local radiation therapy has lengthy been recognized as effective in palliation of bone ache, with as a lot as 80% receiving reduction and up to 50% full reduction from this pain (15). Even a single eight Gy dose has been shown to present pain aid equal to longer courses of palliative care, although retreatment is extra probably (16). Passive mattress bodily remedy and therapeutic massage could typically restore circulation and relieve strain on joints and muscles and provide important symptom improvement. Additionally, using chilly or heat compresses can lead to muscle relaxation with concurrent improvement of signs. With ovarian cancer, gastroparesis, large and small bowel involvement, in addition to frank obstruction could trigger vital nausea. With cervical cancer, nausea could additionally be extra derived from massive bowel, anal, or sigmoid obstruction. Unfortunately, there are often a quantity of areas of involvement which make surgical options unacceptable. Colostomies or ileostomies ought to be thought-about as a preventative measure while the patient is well enough or to palliate situations similar to rectovaginal or vesicovaginal fistula the place a diversionary procedure is more probably to bring a big relief of signs with out too much morbidity. Other choices if obtainable could embody gastric percutaneous drainage systems placed with endoscopic or surgical approaches or gastrointestinal stents in uncommon circumstances. Nausea as a outcome of opioids is usually brief lived and averted by utilizing antiemetics such as metoclopramide at the initiation of therapy. Pharmacological administration for pain with opioids and different medications can add to the symptoms and as more ache drugs or nausea drugs are added, the ensuing constipation additional complicates the image. Standard remedies exist for most sources of nausea and vomiting similar to metoclopramide for gastroparesis, octreotide and glucocorticoids for bowel obstruction symptoms, relieving strain symptoms with ascites with a port or repeated paracenteses (22), haloperidol for hepatic dysfunction and other metabolic disturbances, and cyclizine for mind metastases. Antiemetics used for nausea should work around the clock and, like a pain management technique, have a technique for breakthrough nausea and vomiting that permits for escalation of therapy. Management of gastrointestinal signs Loss of urge for food Loss of appetite or anorexia is common throughout remedy for cancer and at the finish of life. The remedy always is determined by causative components and the general distress the symptom is inflicting the patient. During most cancers remedy, efficient antiemetic treatment can forestall lack of appetite related to delicate nausea. However, the symptom of lack of appetite has different drivers similar to opioidrelated suppression of urge for food, gastric dysfunction, constipation, and simply disease progression. Options to just deal with the symptom are typically a progesterone or a glucocorticoid, each of which have limited efficacy (18). The difficult concern for end of life palliative care is the social and cultural that means attached to eating and feeding the sick that can make it tough for patients and families to settle for that lack of hydration or discount in eating is normal in the course of the transition to death. Discussions with the patient and household about hydration and nutrition type an necessary part of understanding the process of dying and should be part of the care offered. The most common source of constipation for ladies receiving palliative care is from other drug use, primarily opioid use for ache control. Disorders of electrolytes (magnesium, potassium, and calcium) additionally contribute and depending on common status might warrant remedy. Finally, lack of motility because of ascites and tumour studding of the bowel can also contribute. Generally, stimulant remedy with senna or bisacodyl must be began concurrently with opioid use and additional brokers added as needed to manage constipation. In the setting of palliative care where hydration is proscribed, using bulking brokers similar to psyllium or methylcellulose should be limited as they require hydration for efficacy. In some circumstances of extreme and Faecal incontinence and fistula administration the uncontrolled leakage of bowel contents happens with faecal incontinence and enterocutaneous and enterovaginal fistulas in girls with gynaecological malignancies. In the palliative care setting, where no further surgical intervention is acceptable, the introduction of suction-based or adverse pressure wound management systems has allowed for better management of enterocutaneous fistulas and restricted the skin publicity to the often highly caustic material. Lacking access to these approaches, ostomy management with ostomy baggage and careful pores and skin protection can restrict skin breakdown and ache but can be difficult with excessive output small bowel enterocutaneous fistulas (23).
Direct end-to-end anastomosis-ureteroureterostomy Occasional short phase injuries, such as following external penetrating trauma or surgery. The capacity to stretch the ureter to allow an overlapping spatulated anastomosis is considerably restricted, even with full mobilization of both ends of the ureter and mobilization of the kidney as well so as to shift it downwards to help reduce tension. Nonetheless, it should all the time be thought of for prime ureteric drawback; whereas for distal ureteric problems a psoas hitch is probably safer nevertheless quick the ureteric defect appears to be. Psoas hitch, Boari flap, and ureteric reimplantation the psoas hitch21 and Boari flap22,23 procedures are sometimes regarded as two options for dealing with the same drawback. When the bladder could be mounted by sutures to the psoas minor tendon, or to the psoas major muscle if the psoas minor tendon is absent, then it goes to be obvious if the ureter can be implanted into the psoas hitch without tension. In this case, a series of short transverse incisions on both sides will permit the bladder to be stretched upwards extra simply. Then, from inside the bladder, the bladder epithelium can be incised at an appropriate level for a ureteric reimplantation and a subepithelial tunnel created. A ureteric stent is then generally placed and the bladder closed over a suprapubic catheter. Then we take away the stent and clamp the suprapubic catheter for a trial of voiding and remove the suprapubic catheter the following day. This will involve mobilization of the ascending or descending colon up as far as the hepatic or the splenic flexure relying on the facet. An incision was made through the inferior aspect of the renal pelvis, via the renal parenchyma and infundibulum and into the decrease pole calyx; and an ileal section was then interposed between it and the bladder to allow free drainage of each urine and calculous material. It is feasible to tailor the ileal section and attempt a tunnelled reimplantation into the bladder, however there seems little point in doing this. Then, rigorously dissecting underneath the mesentery within the plane between the superior mesenteric vessels and the great vessels, the ureter could be passed over to the contralateral aspect. An incision is then made into the recipient ureter and the spatulated, transposed ureter is then fastidiously sutured to it with fine interrupted absorbable sutures. Occasionally the bladder could additionally be relatively regular and a psoas hitch or Boari flap could additionally be possible, however even in delicate irradiation cystitis that is unlikely to be achievable. Between the 2 extremes, there may be a bladder which is value preserving as a end result of it has some useful capacity and the patient has a functioning sphincter mechanism and is continent. In such sufferers, an augmentation cystoplasty might allow preservation of normal voiding as properly as allowing anastomosis of the wholesome ureter(s) to the bladder. The different is to do a subtotal cystectomy and substitution cystoplasty using the best colon and reimplanting the affected ureter, or both ureters, immediately into the cystoplasty or, together, to the ileal tail. All patients should however be counselled that clean intermittent self-catheterization could also be necessary and it might be unwise to proceed with this kind of surgical procedure unless the patient has not solely consented to self-catheterization however has also proved that she can do it.

The issues of urethral stricture disease are dealt with within the next chapter and of urethral trauma in a later chapter. Congenital problems similar to exstrophy/epispadias, are mentioned in the section on paediatric urology however will be referred to right here insofar as they may cause persistent problems in later life that require reconstructive urology. In these sufferers, the issue in pathophysiological phrases is a variable combination of uncontrollable overactivity of the bladder, a lack of coordination between the bladder and the sphincter, a loss of normal bladder sensation, and sphincter weak spot. Treatment in these sufferers by augmentation cystoplasty works, not simply by rising bladder capability (although this can be valuable in some), but by splitting the bladder roughly completely into two halves so that it could not contract in a coordinated style. Augmentation cystoplasty Neuropathic bladder the neuropathic bladder is handled in detail in previous chapters, but there are some aspects regarding surgical remedy that deserve dialogue here. These sufferers current with incontinence and a few will have recurrent urinary infection.
The second technique is to change the therapeutic goal to the most cancers (plus a margin) as an alternative of the organ harbouring the most cancers. Both surgical procedure and radiotherapy have seen an escalation of complexity with minimal features. For instance, a evaluation has demonstrated few variations in quality-adjusted life years among the many various surgical methods; surgical methods tended to be more practical than radiation, though mixed external beam and brachytherapy radiation remedy for high-risk illness was the exception. Prostate most cancers biology-multifocality, the index lesion, and the idle lesion the query then arises in regards to the extent and nature of the margin. It has served as the entry level to focal remedy for many of the early section research. There is proof that progression is determined by tumour volume, and that the key threshold lies approximately at 0. Moreover, the dominant tumours are inclined to be the most closely associated with extracapsular extension. Further proof comes from the rising number of research that try and phenotype the molecular genetics of both prostate lesion and metastases. For example, low-risk lung, thyroid, and bladder cancers are or have undergone such recalibration. In reality, such a recalibration has already occurred a selection of times, as histopathologists have redefined (and lowered the brink for) what constitutes a specific Gleason sample. The first from Rotterdam and Helsinki comprised 509 males; of those, 381 were low threat, and 128 had been deemed to be intermediate risk. Just over a third within the low-risk group underwent treatment and just over half of the intermediate threat group crossed over to more radical therapy. However, by danger group, respectively, the next remained on surveillance: 133 (59%), fifty eight (50%), 46 (50%), and three (50%). Despite these information indicating safety,42 only one in 10 within the United States and four in 10 of men within the United Kingdom with low-risk disease are allotted to active surveillance. However, focal remedy has been seen by many, predominantly in the United States, as an alternative selection to energetic surveillance. What is required is threat stratification of high precision, clear communication of the danger stratification, and an openness to shared decision-making. This would require giant cohorts monitored over one to 20 years and adjusted for danger. Higher likelihood of complete remedy however significant rates of genitourinary toxicity. Higher probability of complete ablation with fewer genitourinary toxicity in comparison with whole gland. Targeted biopsies show Gleason 3+4 or 3+3 most cancers Targeted biopsies show Gleason 4+4 most cancers Transrectal biopsies show Gleason 3+3 cancer Imaging Ultrasound has not been great at localizing prostate most cancers. Most of the successes have been in single centre collection however have proved difficult to reproduce. The quality of the imaging is compromised by post-biopsy artefacts, and beneath optimum circumstances must be carried out prior to a biopsy. Encouraging results (admittedly from single-centre series) have generated negative predictive values of 90% or higher for the detection of clinically significant prostate most cancers. Greater accuracy upfront will logically translate into lower recurrence or de novo illness charges in untreated areas, in the long run. Ablative expertise There are quite a few methods by which tissue may be selectively destroyed. A focused method to lesions discovered on imaging might have an effect on the chance that a particular man is attributed. Features broadly used to indicate high threat include Gleason score 7, as nicely as parameters to indicate the amount of cancer, corresponding to maximum cancer core size, maximum share cancer, and the variety of constructive biopsies. It is therefore doubtless that new risk prediction fashions primarily based on focused biopsies will be required. Clinical outcomes of focal therapy So far, solely single establishment case collection have reported as full publications, although potential trial data is starting to emerge at the time of writing (Table 6.
Additionally, patients might undergo ache or embarrassment, and consequently fail to generate adequate urinary circulate. Many sufferers have paradoxical incontinence (loss of urine from diverticulum with Valsalva manoeuvres) and this might be troublesome to differentiate from true stress incontinence. Conservative administration is suitable in those with minimal symptoms and those declining surgery. Conservative measures, along with just observation, embody milking the diverticulum after voids to avoid urinary stagnation, and low dose prophylactic antibiotics to prevent infections. This ought to solely be carried out in experienced arms as future continence will rely upon the integrity of the sphincter mechanism. The surgical procedure requires good publicity and could be a technical problem due to the significant vascularity and lack of clear tissue planes because of fibrosis from recurrent an infection. In basic, surgery is greatest delayed until an acute exacerbation has been handled with antibiotics. Counselling of sufferers preoperatively concerning the significant risk of postoperative incontinence is beneficial. Conversely the surgery could correct existing urinary incontinence, consequent upon either sphincteric weak spot resultant from the diverticulum (stress incontinence), or due to pooling of urine in the diverticulum (paradoxical incontinence). The use of videourodynamics is really helpful to define baseline lower urinary tract function. An intensive sequence of case studies reported within the literature clearly defines the related pathological conditions, which can be seen preoperatively in these patients (Table 3. Patients ought to be adequately counselled in regards to the potential for both of these procedures preoperatively. The common rules of excision may be summarized to embody: (i) Mobilization of well-vascularized vaginal pores and skin flap(s); (ii) Complete excision of the urethral communication and diverticulum; (iii) Preservation of urethral anatomy and performance; (iv) Watertight tension-free closure of urethra; (v) Closure in multiple layers with non-overlapping suture lines. Postoperatively, the bladder is drained with a urethral catheter and a suprapubic catheter. The results of excision are typically excellent with treatment rates of over 70% reported. Other complications embody haematoma, urinary tract an infection, and urethral stricture. Excision with reconstruction is the beneficial surgical strategy and has good functional outcomes but is related to a threat of serious issues, corresponding to fistula formation and stress incontinence.

The stigma related to the condition means problems are frequently not volunteered, yet it regularly coexists with urinary incontinence and sufferers with both urinary and faecal incontinence might be generally encountered within the urology clinic. Patients aged over 55 years, diabetics, and individuals who have stress urinary incontinence or detrusor instability are on the highest risk for coexisting faecal incontinence. Clinical features History the kind of incontinence (passive or urge) helps to ascertain the probably cause-passive incontinence is suggestive of internal anal sphincter dysfunction, while urgency and urge incontinence are more suggestive of an external anal sphincter defect or decreased rectal capability. The diploma of soiling is often ascertained by the number of pads or clothing modifications.
