Abstract:
BACKGROUND: A significant proportion of patients develop urinary incontinence early after radical prostatectomy. Posterior reconstruction of supporting tissues has been found to reduce incontinence in open and conventional laparoscopic prostatectomy series. OBJECTIVE: To investigate whether our version of a posterior musculofascial reconstruction will reduce early incontinence and have a beneficial effect on patients' quality of life (QoL). DESIGN, SETTING, AND PARTICIPANTS: One hundred seven consecutive patients undergoing primary robot-assisted radical laparoscopic prostatectomy (RALP) performed by a single surgeon at one tertiary referral oncology institution were alternately assigned (not randomised) to intervention (n=53) or control groups (n=54). SURGICAL PROCEDURE: RALP with median fibrous raphe reconstruction (MFRR) followed by formation of the urethrovesical anastomosis (intervention group) versus standard anastomosis without posterior reconstruction (control group). MEASUREMENTS: Measurements included incontinence at baseline and 3-mo intervals; QoL as measured by a simple questionnaire, the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life-Core 30 (QLQ-C30), and Prostate Cancer Module (PR25) questionnaires preoperatively and at 6 mo postprocedure; tumour characteristics; operative time; fascial preservation score; duration of catheterisation; and anastomotic leakage on cystogram. RESULTS AND LIMITATIONS: For intervention and control groups respectively, mean catheter duration was 11.74 d and 12.74 d (p=0.451); leakage on cystogram was present in six and eight cases (p=0.28); and incontinence (any involuntary urine loss) at 3 mo was 75% and 69% (p=0.391) and at 6 mo was 51% and 43% (p=0.686). Urinary retention occurred only in one case (control group). The percentage of cases returning to baseline in all QoL domains (except insomnia) was similar at 6 mo between the two groups. Short follow-up, lack of blinding, and probable small differences in our method of MFRR performed compared with other studies were identified as significant limitations. CONCLUSIONS: No significant difference in any of the analysed outcome measures was observed. Posterior reconstruction of the musculofascial complex does not appear to improve early urinary incontinence after RALP.
