A modified apical dissection of the prostate to improve the efficiency of vesico-urethral anastomosis (VUA) in laparoscopic radical prostatectomy (LRP) was reported. A total of 42 patients were randomly selected and enrolled in this study. A standard LRP was performed in 21 patients (group 1), whereas a novel, modified apical dissection of the prostate in LRP was performed in another 21 patients (group 2). Surgical data, total operative time, VUA time, extravasation rate, catheterisation time, occurrence of anastomotic strictures, and the early and late continence rates were analysed statistically. No differences in clinical or pathological characteristics were determined between the two groups. The total operative time, VUA time, blood loss and catheterisation time were lower in group 2, which received the novel, modified technique compared with group 1, which received the standard technique to dissect the apex of the prostate (P<0.01 for each variable). Regarding the extravasation rate and the occurrence of anastomotic strictures, no significant differences were found between the two groups (P>0.05 for each). After catheter removal, a statistically significant difference in the continence rates was present at 3 and 30 days post operation in the two groups (P<0.01, respectively). At 90 days post operation, the difference, although still present, was no longer statistically significant (P>0.05). The novel, modified apical dissection of the prostate facilitates the VUA and significantly improves the efficacy of the procedure and early restoration of continence.
