Grip strength, a predictor of stress urinary incontinence after endoscopic enucleation of the prostate for benign prostate hyperplasia.

Objective: To investigate the relationship between the grip strength (GS) and stress urinary incontinence (SUI) after endoscopic enucleation of the prostate (EEP).
Methods: We retrospectively collected 87 patients who underwent EEP at our center from January to December 2023. The associations between GS and post-surgical SUI at immediate, 1, 4, 12 and 24 weeks were analyzed. The cohort was then divided into the SUI and non-SUI group based on the presence of the SUI at 4-week postoperatively.
Results: Of overall 87 patients, 49 (56.3%), 40 (46.0%), 33 (37.9%), 20 (23.0%), and 9 (10.3%) patients presented SUI at immediate, 1, 4, 12 and 24 weeks postoperatively. Significant negative correlations were consistently observed between the GS and SUI till 12 weeks postoperatively, with patients requiring more daily pads presenting lower GS. Compared to the non-SUI group, the SUI group had significantly higher average age (76.0 ± 8.4 vs. 70.1 ± 6.3, P = 0.001), BMI (25.1 ± 2.9 vs. 23.8 ± 2.9, P = 0.040), rates of PKEP (90.9% vs. 72.2%, P = 0.037), CSEA (69.7% vs. 42.6%, P = 0.014) and III/IV ASA score (33.3% vs. 14.8%, P = 0.043), but lower GS (26.2 ± 8.2 vs. 33.3 ± 6.5 kg, P < 0.001). Multivariate analyses identified BMI and GS as independent risk factors for post-operative SUI.
Conclusions: The GS was found to be negatively correlated with post-operative SUI within 12 weeks after EEP and was an independent predictor of SUI at 4 weeks postoperatively.
