Rhabdomyoma of prostate.

An asymptomatic nineteen-year-old white man presented with a markedly enlarged and indurated prostate. Urologic evaluation including cystoscopy, prostatic ultrasound, pelvic computerized tomography (CT) scan, and pelvic nuclear magnetic resonance imaging revealed a prostatic mass impinging on the bladder. Transrectal biopsies returned the pathologic diagnosis of rhabdomyomatous hamartoma. We report the first case in the English literature of extracardiac rhabdomyoma found in the male genitourinary tract.

Genitourinary involvement of systemic sarcoidosis confined to testicle.

We report on a patient with systemic sarcoidosis who presented with a lesion of the genitourinary tract confined to the testicle. Clinically evident sarcoidosis of the testicle has been identified in few instances. Several recommendations in evaluating such lesions have been offered. A consensus on treatment is not yet defined. The therapeutic options are presented and the literature is reviewed.

Traumatic dislocation of testes.

Traumatic dislocation of the testicle is characterized by an ectopically displaced testis as the result of closed injury. We report on 1 patient with subcutaneous inguinal dislocation of the testis that was successfully treated by immediate closed reduction. Forty-nine other cases (36 unilateral and 13 bilateral) have been previously cited. Diagnostic guidelines, our therapeutic approach, and the relevant literature are presented.

Postoperative urinary retention. Guidelines and an algorithm.

Postoperative urinary retention is a common problem after surgery. Prevention includes obtaining a preoperative history and physical, having the patient void just before surgery, avoiding overhydration, and encouraging micturition soon after surgery. Management requires sterile catheterization, when indicated, to drain the urinary bladder completely. Urine cultures must be done when indwelling catheters are used. Antibiotics may be necessary.

Transitional cell carcinoma of bladder in patients under thirty years of age.

Seventy-nine cases of transitional cell carcinoma of the bladder in the age group under thirty years have been reviewed. The diagnosis and treatment are the same as in the older age group. The tumors are usually of low grade and low stage, but they can become more aggressive and more malignant. Contrary to previously held beliefs that transitional cell tumors in the younger age group rarely if ever recur, this series had a recurrence rate of 13.9 per cent with several patients having multiple recurrences. Therefore, the follow-up care of these patients must be vigilant and persistent.

Intravesical thio-tepa in the immediate postoperative period in patients with recurrent transitional cell carcinoma of the bladder.

Recurrent transitional cell carcinoma was treated with prophylactic intravesical thio-tepa in 22 cases. Group 1 patients were treated with 30 mg. twice daily for the first 3 days postoperatively. Group 2 patients were given additional treatment at increasing intervals indefinitely. Before therapy control patients averaged 1 recurrence every 9.5 months. Group 1 patients averaged 1 recurrence per 33 mpnths. Group 2 patients averaged 1 recurrence per 41 months. Leukopenia occurred in only 2 patients. Thio-tepa can be given safely in the immediate postoperative period and is effective in decreasing the recurrence rate of superficial bladder tumors.

Prostaglandin-mediated hypercalcemia in transitional cell carcinoma of the bladder.

A patient with known transitional cell carcinoma of the bladder and hypercalcemia was evaluated for urinary prostaglandin levels when no bone metastases or elevated parathormone levels could be demonstrated. Urinary levels of prostaglandin E metabolite were assessed in relation to serum and urinary calcium levels during treatment. The serum calcium levels decreased from the 13.0 mg. per cent range whenever the rpimary tumor was manipulated (transurethral resection) or when other treatments directed at the tumor were used (radiation therapy and chemotherapy). Serum and urinary calcium levels, and urinary prostaglandin E metabolite decreased when 3 gm. aspirin were given daily. These data suggest that the somewhat unusual hypercalcemia in our patient was caused by a prostaglandin-secreting transitional cell carcinoma. Prostaglandin-secreting tumors are reviewed herein.
