Abstract
Purpose
To investigate whether preoperative urodynamic detrusor overactivity (DO) contributes to post-prostatectomy incontinence (PPI).
Methods
We systematically searched the online PubMed, Embase, and Cochrane Library databases spanning the period of January 1989 to December 2014.
Results
A total of nine articles met the eligibility criteria for this systematic review. The eligible studies included a total of 457 patients with a median number of 58 patients per study (range 17–92). Of the nine studies, five conducted open retropubic radical prostatectomy (RRP), two performed robot-assisted laparoscopic prostatectomy (RALP), and two others utilized multiple modalities. PPI was more likely to occur in patients with preoperative DO [pooled odds ratio (OR) 2.30; 95 % confidence interval (CI) 1.39–3.82; studies 9; participants 419], as compared to patients who were DO negative. Sensitivity analysis using the subgroups of RRP (OR 2.32; 95 % CI 1.11–4.85), RALP (OR 3.41; 95 % CI 1.55–7.47), DO defined as any amplitude of involuntary contraction (OR 2.32; 95 % CI 1.11–4.85), no postoperative intervention (OR 2.32; 95 % CI 1.11–4.85), and outcome evaluation after 6 months (OR 2.32; 95 % CI 1.11–4.85) demonstrated consistent results. Although some comparisons showed inter-study heterogeneity, there was no clear evidence of publication bias in this meta-analysis.
Conclusions
Our meta-analysis results suggest that preoperative DO is another possible underlying mechanism for PPI.
