摘要

In previous studies we noted that the neurovascular bundle was not identical to the bundle of the cavernous nerve fibers. In this study we sought to prove these anatomical findings electrophysiologically and map the autonomic nerve fibers by intraoperative simultaneous measurement of intracavernous pressure and intraurethral pressure.Between January 2004 and May 2005 electrical stimulation was performed in 27 open pelvic surgeries, including 26 radical retropubic prostatectomies and 1 radical cystectomy, using an original bipolar electrode before prostate removal. Nerve stimulation was performed at the base of the so-called neurovascular bundle (point A) and the rectal wall about 1 cm posterolateral, apart from the neurovascular bundle (point B). Intracavernous pressure and intraurethral pressure were measured simultaneously.The mean +/- SD increase in intracavernous pressure was 9.8 +/- 6.3 cm H2O at point A and 13.5 +/- 7.3 cm H2O at point B. Intracavernous pressure at point B was significantly higher than at point A (p = 0.0240). The mean increase in intraurethral pressure was 17.0 +/- 9.4 cm H2O at point A and 11.2 +/- 8.1 cm H2O at point B. Intraurethral pressure at point A was significantly higher than at point B (p = 0.0353).The course of the cavernous nerves did not always agree with the surgically identified neurovascular bundle. The distribution of cavernous nerves was wider than our image of the neurovascular bundle and it existed on the rectal wall posterolateral, apart from the neurovascular bundle rather than the neurovascular bundle itself. The surgically identified neurovascular bundle contained the nerve fibers contributing to urinary continence.
