New treatment modality for penile urethral strictures using a self-expanding and self-retaining coil stent: UroCoil. Follow-up of 16 months after removal of the stent.

Abstract

Twelve penile urethral strictures which were managed in the past (2-21 years) by dilatations, urethrotomies, or by urethroplasty, were treated by an insertion of a temporary but long-term metallic coil stent. In 9 cases, the stent was left in place 6-9 months; in 3 cases, the stent is still in place. During the time the stent was inside, 4 patients who were sexually active before insertion of the stent were able to continue sexual activity. During a mean follow-up time of 16 months (range 4-24 months) after the removal of the stent, in only 1 case did the stricture recur. At present, this new internal device is the only one which can stent the penile part of the urethra temporarily without interfering with the sexual activity of the patient, and without causing pain or the risk of urethral perforation.
