Lower urinary tract injuries associated with pelvic fractures. Diagnosis and management.

Salient points in the assessment of lower urinary tract trauma, the evaluation of the severity of injury, and the establishment of priorities in management.

Neurofibromatosis of the bladder in children: case report and literature review.

A case of plexiform neurofibroma of the lower urinary tract is presented as well as a review of all previously reported cases in childhood. We suggest aggressive management in patients with diffuse disease.

Assessment of potency with the doppler flowmeter

Abstract The Doppler flowmeter was utilized to study penile blood flow in 36 patients. A tenpoint average grading system is devised for the three main penile arteries. Our data indicate the applicability of this device as a means of assessing arterial insufficiency in the penis, enough to produce impotence.

Treatment of extensive renal calculi with extracorporeal surgery and autotransplantation

Two patients with large calculi in solitary kidneys, treated by ex vivo stone extraction and autotransplantation, are presented. The results show this to be a valuable therapeutic modality for difficult renal calculi where an in situ approach would be hazardous.

Fibroma of tunica albuginea

A case of fibroma of the tunica albuginea is presented with a review of the literature on previously reported cases of this rare entity. The characteristics of this lesion, its pathogenesis, and its treatment are considered.

Retroperitoneal conduit. Indications and uses.

Abstract Forty-two patients, of which 21 received retroperitoneal jejunal conduits and 21 received retroperitoneal ileal conduits, were operated on using the standard indications for conduit diversion. Complications were minimal. This technique is useful in preventing internal hernias, parastomal hernias, and volvul us; it will permit using a segment of bowel that has not previously been irradiated; and it will allow easy access to a high pyelointestinal anastomosis. There is no evidence that this technique will interfere with subsequent abdominal surgical procedures.

An Unusual Solution to Complicated Prostatic Urethral Stricture: Modified Pull-Through Urethroplasty-Urethroneocystostomy

A modified transpubic pull-through procedure was used in a failed Solovov-Badenoch pull-through repair of a traumatic prostatomembranous urethral stricture. The modification consisted of an incision of the intracrural septum through which the mobilized bulbous urethra was then passed and anastomosed to the most available dependent portion of the anterior bladder wall. The outcome was an unexpectedly good result that has persisted for more than 30 months. A review of the literature revealed no absolutely similar procedure.

Closed postprostatectomy irrigation-drainage system

Abstract A sterile, closed drainage system described by Miller 1 and this report, will enable the urologic surgeon to utilize vesical irrigation when necessary without breaking continuity of the system and, therefore, without increasing the risk of postoperative infection to the patient.
