We report a case of angiomyolipoma of the penis in a fifty-three-year-old patient. This lesion is rare outside of its usual intrarenal location, and, to our knowledge, has never before been reported to occur in the penis.
Longitudinal cuts of various lengths and depths were made in the area of the external urethral sphincter in 18 male cadavers. The Iglesias resectoscope and the Collings knife electrode were used. Histologic sections of the prostate and of the membranous and bulbous urethra demonstrated that a cut of 2 cm. in length beginning from the verumontanum and 6 mm. in depth was necessary to completely incise the external urethral fibers. This procedure, when performed according to these criteria, effectively decreases urethral resistance, permits adequate bladder emptying and probably eliminates the need for a catheter.
The incidence of ureteral carcinoma in situ at the time of cystectomy for bladder carcinoma is approximately 8.7 per cent. Followup records of 27 such patients as well as records of 6 patients with other ureteral abnormalities were reviewed. Clinically, no postoperative ureteral or upper urinary tract difficulty was noted in 29 of the 30 patients whose records were complete. The ureteral status of the 3 patients lost to followup remains uncertain. One patient had infiltrating ureteral carcinoma and he is well 8 years after cystectomy. Since ureteral carcinoma in situ at the time of cystectomy for bladder cancer has had little influence on the course of these patients, conservative treatment is probably indicated when the lesion is encountered.
