Correlation Between Transurethral Interventions and Their Influence on Type and Duration of Postoperative Urinary Incontinence: Results from a Systematic Review and Meta-Analysis of Comparative Studies

Objective: To perform a systematic review to assess the incidence of transient (<6 months) and persistent (>6 months) stress urinary incontinence (SUI), urge urinary incontinence (UUI), and mixed urinary incontinence (MUI) after transurethral surgeries for benign prostatic hyperplasia. Materials and Methods: A systematic literature search was performed using Embase, PubMed, and Web of Science. We included studies comparing monopolar (M)/bipolar (B) transurethral resection of the prostate (TURP) vs ablation vs enucleation procedures. Incidence of incontinence was assessed using Cochran-Mantel-Haenszel Method and reported as odds ratio (OR), 95% confidence interval (CI), and p-values. Statistical significance was set at p < 0.05 Evidence Synthesis: Twenty-eight studies were included. Incidence of transient SUI was 4.6%, 6.0%, 3.0%, and 2.4% after ablation, enucleation, M-TURP, and B-TURP, respectively. Incidence of persistent SUI was 1.1% after ablation, 1.7% after enucleation and M-TURP, and 1.0% after B-TURP. Incidence of transient UUI was 2.0%, 7.3%, 4.4%, and 2.8% after ablation, enucleation, M-TURP, and B-TURP, respectively. Incidence of persistent UUI was 2.2% after M-TURP. The incidence of transient MUI was 5.1%, 0.8%, 5.4%, and 0.9% after ablation, enucleation, M-TURP, and B-TURP, respectively. Incidence of persistent MUI was 3.1% after ablation and 4.8% after M-TURP. Incidence of transient and persistent SUI and UUI did not differ after TURP vs enucleation. Incidence of transient (OR 3.32, 95% CI 0.41-26.65, p = 0.26) and persistent SUI (OR 4.79, 95% CI 0.52-43.89, p = 0.17) was not significantly higher after ablation. Incidence of transient UUI was not significantly higher after ablation (OR 2.62, 95% CI 0.04-166.01, p = 0.65), whereas persistent UUI did not differ. Incidence of transient MUI was significantly higher after enucleation (OR 3.26, 95% CI 1.51-7.05, p = 0.003). Incidence of transient and persistent MUI did not differ after TURP vs ablation. Conclusions: Ablation, enucleation, and TURP have an impact on all forms of incontinence, but this is transient in most cases with no difference between the groups, except for MUI, which was higher after enucleation vs M-TURP.
