Dilation and internal urethrotomy are useful in a select group (approximately 70% of all patients) who are stricture-free at 3 months, and of whom 50 to 60% will remain stricture-free up to 48 months. A second dilation or urethrotomy for early stricture recurrence (at 3 months) is of limited value in the short term (24 months) but of no value in the long term (48 months), whereas a third repeated dilation or urethrotomy is of no value.

There is no significant difference in efficacy between dilation and internal urethrotomy as initial treatment for strictures. Both methods become less effective with increasing stricture length. We recommend dilation or internal urethrotomy for strictures shorter than 2 cm., primary urethroplasty for those longer than 4 cm. and a trial of dilation or urethrotomy for those 2 to 4 cm. long.

Pelvic lipomatosis is a rare condition characterized by an overgrowth of normal fat in the perivesical and perirectal spaces. Cystitis glandularis, cystica or follicularis has been observed in 75% of the patients with pelvic lipomatosis. Although cystitis glandularis is widely regarded as premalignant few reports have documented its transition to adenocarcinoma. We describe a 41-year-old man with pelvic lipomatosis in whom primary adenocarcinoma of the bladder developed 6 years after a histological diagnosis of cystitis cystica and glandularis was established. To our knowledge this is the second case reported of pelvic lipomatosis associated with proliferative cystitis and adenocarcinoma of the bladder, indicating that intestinal metaplasia of the urothelium may be a precursor of malignancy in these patients.

The clinical records of 67 patients who underwent surgical exploration for stab wounds associated with hematuria were reviewed in an attempt to evaluate the need for mandatory operation and to define criteria for possible nonoperative of such cases. Minor renal injuries without associated intra-abdominal lacerations were found in 61 per cent of the patients. Delayed renal hemorrhage occurred in 15 per cent of the patients despite early exploration, suture and drainage of the kidney, and antibiotic prophylaxis. Of 7 nephrectomies 5 were performed for secondary hemorrhage. Postoperative pulmonary complications arose in 28 per cent of the patients. A policy of mandatory operation on all patients with stab wounds and hematuria led to apparently needless surgery in 61 per cent of the patients in this series. Retrospective analysis revealed that the rate of probably unnecessary operations could have been reduced to 24 per cent by selecting for operation only those patients with signs of severe hemorrhage, associated intra-abdominal injury or major extravasation of contrast material on excretory urography.

A prospective clinical study of 54 patients with stab wounds and hematuria was conducted to evaluate the safety of selective nonoperative management compared to mandatory surgical exploration of these patients. In the absence of signs of severe blood loss, associated intra-abdominal injury or major abnormality on the excretory urogram patients were randomized to undergo mandatory surgery (group 1) or nonoperative management (group 2). Patients with signs of severe blood loss, associated intra-abdominal injury or gross abnormality on excretory urography were selected for an operation (group 3). The rate of probably needless operations (defined as minor renal injury without associated intra-abdominal lacerations) was 78 per cent in group 1 and 0 per cent in group 3. Pulmonary complications occurred in 33 per cent of the patients in group 1, 4 per cent in group 2 and 38 per cent in group 3. Despite an operation delayed renal hemorrhage occurred in 1 patient (5 per cent) in group 1 and 2 (15 per cent) in group 3, and resulted in nephrectomy in 2 of these patients. No instance of secondary hemorrhage occurred in group 2 patients. The mean length of hospitalization was 9, 5 and 11 days in groups 1 to 3, respectively. Our results indicate that the selective nonoperative management of patients with renal stab wounds can lead to a decrease in the rate of unnecessary operations, postoperative complications and length of hospitalization compared to a policy of mandatory surgical intervention.

There is no significant difference in efficacy between dilation and internal urethrotomy as initial treatment for strictures. Both methods become less effective with increasing stricture length. We recommend dilation or internal urethrotomy for strictures shorter than 2 cm., primary urethroplasty for those longer than 4 cm. and a trial of dilation or urethrotomy for those 2 to 4 cm. long.

We report a case of pelvic lipomatosis with ureteral obstruction and vesicoureteral reflux. In addition to computerized tomography, nuclear magnetic resonance imaging provided definite and graphic proof of the diagnosis. Operative treatment consisted of ureteroileocystostomy.
