Urethral stricture in the tropics may be a serious public health problem; the majority of cases are caused by the gonococcus. The pathology is varied, and many advanced cases with complications are seen. Most strictures are seen in the posterior urethra, where fibrosis and narrowing may extend from a short length of under 5 mm to well over 10 cm. A wide variety of complications occurs. Diagnosis is easy when the patient presents in acute retention or with a history of difficult micturition, but more difficult when stricture is the underlying cause of perianal abscess, gangrene of the scrotum caused by extravasation, uremia or hypertension, hernia or rectal prolapse, urinary infection, or elephantiasis of scrotum with multiple fistulae. A careful history is helpful, paricularly if previous gonorrhea is involved. Physical examination varies according to mode of presentation and complications; a rectal examination and neurological examination should be included. Definitive investigation to prove the presence of a stricture includes urethrography and urethroscopy, if facilities are available. Indirect methods of diagnosis include tests for hemoglobin, blood urea, plain X-ray of the whole urinary tract, urinalysis, and others. It is preferable to leave instrumentation until last in diagnostic cases, to avoid infection, but a diagnostic bougie may be passed under strict aseptic conditions prior to treatment. The mainstay of treatment is regular bouginage for life, which is best done in a bougie clinic held at regular intervals. Equipment for bouginage, in order of desirability, includes soft plastic bougies, straight metal bougies, or curved metal bougies in larger sizes, a large stainless steel instrument tray, a basin for sterile water, and lubricant. Care should be taken during bouginage not to pass bougies into acutely inflamed strictures, and not to overstretch the urethra. Plastic bougies are preferable, until a stable situation has been reached. Surgery is indicated for a persistently impassable stricutre, for 1 requiring difficult bouginage at frequent intervals with many failures, for an established false passage, and for complications, especially bladder neck stenosis. Instructions for intravenous pyelograms and for urethrography from below and above, and diagrams of urethrograms indicating various pathological states and a diagnostic schema for urethral stricture are included.

The authors present a 51-year-old patient with a severe case of gas-producing phlegmone following incision of a perianal abscess. Early diagnosis and extensive surgical excision during the first 12 hours from the onset of symptoms are crucial. Treatment of sepsis complicated by multiple organ failure: lung insufficiency (respiratory distress requiring mechanical ventilation), kidney insufficiency (requiring rehydration, furosemid, manitol), circulation (blood derivatives, saline, colloid solutions, cardio tonics, anti-arrhythmic drugs) and liver must be aggressive. Hyperbaric oxygen therapy is essential with repeated identification of aerobic and anaerobic bacteria (hemoculture, tissue sample, wound swab), their sensitivity to antibiotics and repeated surgical debridement of the wound. Following this treatment the patient was transferred to plastic surgery where Thiersh transplants covered skin defects. He survived with an abdominal wall hernia due to a team effort and aggressive multidisciplinary treatment by the general surgeon, anesthesiologist, hyperbaric medicine specialist, microbiologist and plastic surgeon. He refused hernia repair.

Abdominal hernias are very frequent in cirrhotic patients with ascites. The hernias usually present as umbilical, inguinal, incisional, or femoral. However, these patients can also develop uncommon hernias such as pelvic hernias because of pelvic floor weakness and high abdominal pressure due to ascites. We present the first case of a cirrhotic patient with ascites that developed a giant sciatic hernia mimicking a perianal abscess.
