The Journal of Urology
|April 1, 1979
Summary
Transurethral resection of the external sphincter effectively cured 75% of vesicoureteral reflux but showed a 65% success rate for reducing residual urine. Postoperative impotence occurred in 2.8% of men undergoing this sphincter surgery.
Area of Science:
- Urology
- Surgical Procedures
Background:
- Transurethral resection of the external sphincter is a surgical technique.
- External sphincter dysfunction can lead to urinary issues.
Purpose of the Study:
- To evaluate the efficacy of transurethral resection of the external sphincter.
- To assess outcomes including impotence, vesicoureteral reflux cure, and post-voiding residual urine reduction.
Main Methods:
- The study involved 60 men undergoing transurethral resection of the external sphincter at the 12 o'clock position.
- The procedure was performed 61 times.
Main Results:
- A 2.8% incidence of postoperative impotence was observed.
- A 75% cure rate for vesicoureteral reflux was achieved.
- A 65% success rate in decreasing post-voiding residual urine after 6 months was noted.
Conclusions:
- Transurethral resection of the external sphincter demonstrates effectiveness in treating vesicoureteral reflux.
- The procedure has a moderate success rate in reducing post-voiding residual urine.
- Potential complications such as impotence should be considered.
