PE 08. Effect evaluation of penile dorsal nerve neurotomy in patients with premature ejaculation

Objectives: To evaluate the safety and effectiveness of penile dorsal nerve neurotomy in patients with premature ejaculation.

Methods: From November 2008 to March 2011, 146 outpatients received penile dorsal nerve neurotomy for treating premature ejaculation (PE), during which two main nerves were retained and the remaining branches were removed. The patients started sexual activities four weeks after surgery and were followed up for 2 months to 2 years. The intravagina ejaculation latency and the satisfaction degree of intercourse before and after operation were assessed using vibration sensory threshold (VPT) test.

Results: VPT reached normal range in most cases, along with remarkably prolonged intravaginal ejaculatory latency time (IELT) and improved coitus satisfaction degree. Finally 75 cases were cured, 34 cases improved, and 37 cases ineffective, yielding a total effective rate of 74.7%. No wound infection, bleeding, or erectile dysfunction was reported during follow-up.

Conclusions: VPT is a non-invasive, objective, and safe approach for dorsal penile nerve sensory detection. Penile dorsal nerve neurotomy can extend IELT and raise coitus satisfaction degree, and therefore can be applied for treating premature ejaculation.
