Prostatic titanium urethral stents. A new treatment option for obstructive uropathy: early clinical results and indications.

An expandable titanium stent was used as an alternative to standard treatment for urinary obstruction in 20 men. Six patients had recurrent urethral strictures. Fourteen patients had obstruction secondary to benign prostatic hyperplasia (BPH) and were considered high risk surgical candidates. Complete results with a mean follow-up of 12 months are available for 11 patients. Four of the six stricture patients are currently unobstructed. All seven of the available men with BPH are voiding well. No side effects have been related to the stents, and no encrustations or calculi have formed.
