Use of polyvinyl alcohol in treatment of bladder and prostatic hemangioma.

Hemangiomas of the bladder and prostate are rare. There have only been approximately 80 cases described in the literature, the majority of which were of bladder origin. Treatment has varied from partial cystectomy to use of the neodymium yttrium aluminum garnet (Nd-YAG) laser. Herein, we report a case of vesical neck and prostatic hemangiomas successfully treated with super-selective intra-arterial injections of polyvinyl alcohol.

Early detection of stage A prostate carcinoma: combined use of prostate-specific antigen and transrectal ultrasonography.

We prospectively studied 103 men who had normal results on digital prostate examinations but had bladder outlet obstruction secondary to prostatic hypertrophy and needed transurethral prostatectomy. All men underwent a preoperative transrectal ultrasonographic examination of the prostate and prostate-specific antigen (PSA) level determination. A total of 30 cancers were ultimately detected, 22 (73%) of which were detected preoperatively by either an abnormal ultrasonogram or elevated PSA levels (or both). Eight of these men were spared transurethral prostatectomy and had definitive treatment based on transrectal biopsy and appropriate staging evaluation. For PSA and ultrasonography combined, the sensitivities and negative predictive values for cancer (92% and 94%, respectively) were superior to the specificities and positive predictive values (71% and 64%, respectively). The combined use of both studies is recommended to rule out cancer in candidates for prostatectomy but not to routinely screen the general male population older than 40 years.

Bilateral ureteral obstruction secondary to condylomata acuminata of the urinary bladder.

Condyloma acuminatum is a viral infection of near epidemic proportions. Both men and women are affected equally. Most lesions are on the external genitalia and the mucous membranes of the urethra or the vagina. A rare occurrence of condyloma acuminata is involvement of the urinary bladder. To date, only 11 cases have been reported. We describe two additional cases, both with bilateral ureteral obstruction. Current urologic management and review of the literature are presented.
