Incidence and risk factors for postoperative urinary incontinence after various prostate enucleation procedures: systemic review and meta-analysis of PubMed literature from 2000 to 2021.

Overview
abstract
PURPOSE: To evaluate the risk of urinary incontinence (UI) after various prostate enucleation procedures (PEP). METHODS: PubMed was searched from January 2000 to July 2021 for studies investigating UI after PEP. The articles were divided into 5 subgroups: holmium, thulium, greenlight laser, electrocautery, and simple prostatectomy. Meta-analysis was performed to examine rate of stress (SUI), urge (UUI) or unspecified UI at short (< 3 months), intermediate (3-6 months), and long-term (> 6 months). The impact of age, prostate size, surgery time, laser time, postoperative nadir PSA level and technical modifications on UI was analyzed. RESULTS: Most (69.4%) of 49 articles included employed holmium laser. There was no significant difference in incidence of short-, intermediate-, and long-term UI, SUI and UUI between five sub-groups and within different technical modifications. Although not statistically significant, the incidence of UI was higher (15%) at short-term with green-light and simple prostatectomy (95% CI 9-23 and 1-84), and higher (4%) at intermediate-term with holmium laser (95% CI 2-8). SUI was more prevalent at short-term with holmium laser (4%; 95% CI 2-5%), and at intermediate term with simple prostatectomy (3%; 95% CI 1-14). UUI was higher in the thulium group (10%, 95% CI 7-16). Increased age, surgery time, laser time and prostate size up to 80 cc were associated with higher UI. There was no correlation between postoperative PSA and UI. CONCLUSIONS: There is no significant difference in incidence of UI, SUI and UUI after various PEP. Patients age, prostate size, surgery and laser time are linearly associated with UI.
