摘要
Incontinence after radical retropubic prostatectomy (RRP) is one of the greatest worries for all patients. One of the possible reasons for this urinary incontinence is a postoperative deficiency of the external striated urethral sphincter (EUS) complex and continence nerves. This study evaluated the application of a modified simple technique to dissection of the apical prostate in laparoscopic radical prostatectomy (LRP) and assessed the rate of urinary continence. @@@ A total of 104 patients were randomly selected using envelopes and enrolled in this study. A standard LRP was performed in 52 patients (standard LRP group) and a modified technique for simple dissection of the apical prostate in LRP was performed in another 52 patients (modified LRP group). The urethra was dissected and transected at the apex of the prostate, proximal to the nerve-distributing rhabdosphincter using sharp scissors to avoid damage to the EUS complex and continence nerves. In all patients, a pad test was performed on 3, 30 and 90 days postoperatively and correlated with urinary continence. Continence was defined as zero pads or a liner used for security reasons only. @@@ After catheter removal, the continence rates were regained in 66, 85 and 96% of patients in the modified LRP group compared with 28, 55 and 91% of the patients in the standard LRP group at 3, 30 and 90 days, respectively. A statistically significant difference was present at 3 and 30 days (p < 0.01, respectively). At 90 days, the difference, although still present, was not statistically significant (p > 0.05). @@@ In this preliminary study, the technique of simplified apical dissection of the prostate in LRP appears to be an easy and feasible technique in early recovery of urinary continence. Further long-term and larger sample studies are necessary to elucidate the modified technique in LRP on early restoration of urinary continence.
