Purpose:
To report short-term potency outcomes with a cautery-free technique (CFT) to preserve the neurovascular bundles (NVB) during robotic laparoscopic radical prostatectomy (LRP).
Patients And Methods:
All men were <66 years of age and had a Sexual Health Inventory in Men (SHIM) score of 22 to 25. They underwent unilateral or bilateral dissections. Group 1 (N = 23), the study group, had preservation of the NVB with CFT. Group 2 (N = 36) had traditional dissection using bipolar cautery. Data were collected prospectively via validated questionnaires. Potency was defined as an erection adequate for vaginal penetration.
Results:
At 3 months, 10 patients (43%) in the CFT group reported potency versus just 3 (8.3%) in the bipolar-cautery group (P = 0.003). Additionally, only 2 (18%) of those having CFT reported zero penile fullness compared with 15 (68%) in the bipolar-cautery group (P = 0.01).
Conclusions:
The technique of controlling the vascular pedicle of the prostate and dissecting the NVB without cautery produced significant improvement in potency outcomes at just 3 months.
