title: Heat-expansible permanent intraurethral stents for benign prostatic hyperplasia and urethral strictures.
abstract: We report our experience with the insertion of a new thermoexpansible permanent intraurethral stent, the Memotherm. We treated 49 patients, 25 with benign prostic hyperplasia (BPH), 21 with recurrent urethral strictures (2 cervicourethral and 18 bulbar and 1 of a vescicourethral anastomosis after radical prostatectomy), and 3 with sphincterotomies (2 for dyssynergia and 1 with incontinence plus stenosis). The patients' ages ranged from 24 to 84 (mean 59.7) years. In all patients, stent insertion was achieved without any operative problem. In two patients, stents were removed (one in the BPH group and one in the urethral stricture group), and at long-term follow-up, we have seen two patients with severe mucosal hyperplasia.
