Ureteroscopy: the initial experience.

A prospective study of our first 81 cases of ureteroscopy using extended length rigid endoscopes was performed. Of 55 stone manipulations attempted in 51 patients by 6 endoscopists 38 (69 per cent) were successful. Analyzed sequentially, removal was successful in 12 of 23 attempts (52 per cent) among the initial 40 patients and in 26 of 32 (81 per cent) among the subsequent 41 patients. Of 11 calculi larger than 1 cm. and of 23 positioned above the iliac vessels 7 (64 per cent) and 11 (48 per cent), respectively, were removed successfully. Disimpaction by ureteroscopic manipulation combined with extracorporeal shock wave lithotripsy was successful in 4 cases of upper ureteral calculi not treatable by extracorporeal shock wave lithotripsy alone. Diagnostic and therapeutic uses of the ureteroscope in addition to treatment of ureteral calculi have included the delineation of ureteral filling defects (9 patients), fulguration of known low grade tumors (4) and dilation of ureteral strictures (5). In 10 patients information was obtained endoscopically that was not possible by standard diagnostic techniques. The direct visual approach to the ureter has distinct advantages over blind ureteral instrumentation.

Sickle cell trait: forgotten cause of hematuria in white patients.

Extensive evaluations for intermittent gross hematuria, including selective renal arteriograms, failed to reveal the etiology of bleeding in 2 whtie patients. Sickle cell preparation and hemoglobin electrophoresis, obtained as long shot tests, revealed sickle cell trait in both patients. Both patients were treated successfully with low doses of epsilon aminocaproic acid. Sickle cell prepration and hemoglobin electrophoresis should be included in the evaluation of every patient, white or black, with unexplained hematuria.

Autosuturing device in intestinal urinary conduits.

The autosuturing device has been used to close the base of 41 urinary intestinal conduits: 12 colonic, 25 ileal, and 4 jejunal. The techniques are described. There were no urine or bowel leaks, although in one postoperative gastrointestinal bleeding occurred in association with a partial small-bowel obstruction probably related to the stapled enteroanastomosis. Use of the instruments reduced peritoneal contamination and facilitated conduit manipulation. Operating time was reduced. Four patients have passed stones composed of struvite and apatite with staples embedded within. The autosuturing device should be considered an alternative rather than a substitute for conventional proximal conduit closure and bowel anastomoses.

Replacement of the damaged or neoplastic ureter by ileum.

Ileum was used as a ureteral replacement in 12 patients, 7 of whom had solitary kidneys. The conditions that necessitated an operation included renal pelvic and ureteral complications of calculi, a variety of traumatic ureteral injuries, retroperitoneal fibrosis and ureteral neoplasms. Renal function has been well preserved and electrolyte imbalance has been minimal.

Sex cord-stromal (gonadal stromal) tumors of the testis: a report of 5 cases.

Sex cord-stromal (gonadal stromal) tumors of the testis account for less than 4 per cent of the testicular tumors. The Leydig cell tumor in a child may produce isosexual virilization (case 3). In the adult it may have no endocrine manifestation (case 1) or gynecomastia and decrease in libidio may result from production of estrogens (case 2). Sertoli cell tumors (case 4) and granulosa cell tumors (case5) are rare.

Experience with the electrohydraulic disintegrator.

Experience with the electrohydraulic lithotrite in treating 14 cases of bladder calculi is reported. This revolutionary lithotrite is applicable to most bladder stones and is associated with few complications.

Control of massive prostatic bleeding with angiographic techniques.

In the 4 cases reported herein angiographic techniques with selective bilateral hypogastric embolization were used to control severe prostatic hemorrhage. The technique is offered as an alternative, non-operative procedure in the management of bleeding when other modes of therapy contain significantly higher potentials for morbidity and mortality.

Angiographic management of bleeding secondary to genitourinary tract surgery.

Angiographic methods were applied to control bleeding in 2 patients following genitourinary tract operations. In 1 patient hemorrhage into the prostatic bed after needle biopsy of the prostate was controlled with embolic occlusion of branches of the hypogastric arteries. In the second patient bleeding from the ileum following ileal loop cutaneous diversion was controlled with the infusion of vasopressin into the superior mesenteric artery. Therefore, angiography offers an attractive alternative to an operation in the management of postoperative hemmorrhage from the genitourinary tract.
