title: Sexual function after a urethroplasty for membranous-prostatic urethral stricture.
abstract: A review is presented on the anatomy of nerves involved in penile erections, with respect to their exit from the pelvis. More detailed information is required. A road map of these nerves as they approach, traverse and exit from the urogenital diaphragm is needed, which would allow the surgeon to properly design the stricture repair operation. Case reports are presented that suggest that the membranous urethra and urogenital diaphragm can be incised posteriorly in the midline without destroying the penile erection. Since subjective evaluation of penile erection may be misleading a method for objective evaluation is required. Further information regarding the effect on potency of the various types of operations involving the urogenital diaphragm for membranous-prostatic urethral strictures needs to be carefully accumulated.
