Ureteral injuries during vascular surgery.

The rapid increase in the number of vascular surgical procedures done has led to a new class of iatrogenic ureteral injuries. Vena caval ligation, bilateral lumbar sympathectomy, bypass procedures and abdominal aortic aneurysmectomy produce the majority of these injuries. Established principles useful in the repair of iatrogenic injuries following a gynecologic or colonic operation often are inapplicable.

Transitional Cell Carcinoma of the Ureter Associated with Cyclophosphamide Therapy for Benign Disease: A Case Report

AbstractCyclophosphamide-induced uroepithelial tumors of the bladder and renal pelvis have been reported previously. We present the first case of transitional cell carcinoma of the ureter associated with cyclophosphamide therapy.

Fibroepithelial polyp of renal pelvis

Abstract Primary mesodermal tumors of the renal pelvis are rare. Herein, the eighth case of fibroepithelial polyp of the renal pelvis is reported, this occurring in a nonfunctioning kidney. The diagnosis and treatment of fibroepithelial polyp is discussed and the literature reviewed.

Carcinoma of prostate metastatic to penis

A case report of prostatic carcinoma metastasizing to the penis is presented. Review of the literature revealed only 54 cases reported to date. With survival rates ranging from two to six months, the prognosis is gloomy. The most commonly used method of treatment was local wide excision of the lesion.

Successful treatment of lupus erythematosus cystitis with DMSO

Systemic lupus erythematosus patients sometimes present with pathologically confirmed lupus interstitial cystitis. Treatment with prednisone has not been observed to be successful. Two patients are presented who were successfully treated with intravesical dimethyl sulfoxide (DMSO).

Papillary cystadenocarcinoma of the prostate.

We report an unusual case of papillary cystadenocarcinoma of the prostate causing symptoms of prostatism.

Prostatic needle biopsy in patients after abdominoperineal resection

Abstract Following abdominoperineal resection, the prostate cannot be palpated rectally. A prostatic needle biopsy can be performed by relying on the IVU and sonogram as guides to localize the prostate and the area undergoing biopsy.

Metastatic carcinoma of prostate and bladder causing intestinal obstruction

Abstract Three well-documented cases of lower genitourinary neoplasms spreading preferentially to the gastrointestinal tract causing obstruction are discussed. This uncommon route of metastatic dissemination is reviewed, and hypotheses and explanations are offered.
