Long-term outcome of permanent urethral stents in the treatment of detrusor-sphincter dyssynergia.
OBJECTIVES: To evaluate the long-term efficacy of a permanently implanted urethral stent in the treatment of spinally injured patients with detrusor-sphincter dyssynergia. PATIENTS AND METHODS: Twelve patients underwent external sphincter stenting in our institution between 1988 and 1990. They were reviewed at least annually and investigated with serial urodynamic and ultrasonographic studies. RESULTS: Ten patients were followed for at least 5 years. Two patients required stent removal and five patients developed bladder neck obstruction requiring surgical intervention. There were no problems with stent migration, ulceration or infection. CONCLUSION: Stenting is an effective alternative to sphincterotomy in the long-term, although secondary bladder neck obstruction is a frequent problem.
