OBJECTIVETo discuss the effect of urine control after radical retropubic prostatectomy by preserve the membranous part of sphincter urethrae and the neurovascular bundle, or to rebuild the bladder neck.

METHODSThe radical retropubic prostatectomy was performed on a total of 32 cases of prostate cancer. We preserve the membranous part of sphincter urethrae and the neurovascular bundle lateral to the prostate. We evaginate the posterior wall of the bladder adequately and make an additional folding stitch to rebuild the bladder neck.

RESULTSThe follow up is of 6-72 months. All patients could void without difficulty, no tumor recurrence and only 2 cases occurred slight incontinence. Other 30 cases regained the ability of controlling their urinations within 6 months.

CONCLUSIONSThe incontinence after radical retropubic prostatectomy could be reduced by the method of preserving the membranous part of sphincter urethrae and preserving the neurovascular bundle lateral to the prostate in operation. It could also be avoided by evaginate the posterior wall of the bladder adequately and make an additional folding stitch to the bladder neck.
