Abstrakt: Objectives: To examine association between post-prostatectomy incontinence (PPI) severity and weight changes before and after restoration of continence via artificial urinary sphincter (AUS).
Methods: Single surgeon, retrospective review of urologic prosthetic surgery (UPS) after radical prostatectomy (RP). A cohort of post-RP inflatable penile prosthesis (IPP) patients served as a surgical control. Body Mass Index (BMI) and total body weight were assessed pre and post-UPS. Multivariable linear regression was utilized to assess BMI changes post-UPS.
Results: 187 AUS and 63 IPP patients met selection criteria. Greater PPI severity was associated with faster BMI gain after RP (coeff. 0.14 kg/m2, P = 0.03, per pad used) and magnitude of incontinence improvement (mean reduction in daily pad use) after AUS insertion was associated with greater BMI reduction at 12 months post-UPS (coeff. - 0.13 kg/m2, P = 0.04). On multivariable regression, AUS insertion was associated with a decrease in BMI by - 2.83 kg/m2 12 months post-UPS (P = 0.02). Twelve months post-UPS, men with AUS exhibited a mean BMI reduction of -1.0 kg/m 2 compared to a mean BMI increase in the IPP cohort of 0.4 kg/m 2 (P < 0.01). Compared to IPP, AUS patients experienced absolute body weight reduction by 6 kg [Median(IQR): 90.4 (80.3-100.1) vs 96.4 (87.1-108.8) kg, P = 0.03], with nearly one-third having clinically significant weight loss (>5% body weight) at 12 months post-UPS (31.8% vs 8.3%, P < 0.01).
Conclusion: Severe PPI appears to be associated with weight gain and correction of PPI via AUS insertion with weight loss.
