Summary
High subcutaneous fat thickness (SCFT) is linked to lower bladder voiding efficiency and increased urinary incontinence after robot-assisted radical prostatectomy (RARP). SCFT may predict lower urinary tract dysfunction (LUTD) post-surgery.
Area of Science:
- Urology
- Surgical Oncology
- Radiology
Background:
- Obesity is a known risk factor for lower urinary tract dysfunction (LUTD) following robot-assisted radical prostatectomy (RARP).
- Accurate obesity assessment is crucial for predicting postoperative outcomes.
Purpose of the Study:
- To evaluate the predictive value of subcutaneous fat thickness (SCFT) and periprostatic fat thickness (PPFT) for LUTD after RARP.
- To determine if SCFT and PPFT are useful obesity measures for predicting postoperative urinary function.
Main Methods:
- Retrospective analysis of 536 patients undergoing RARP.
- Preoperative MRI measurements of abdominal SCFT and PPFT.
- Postoperative assessment of bladder voiding efficiency (BVE) and urinary leakage at 1, 3, 6, and 12 months.
- Univariate and multivariate regression analyses to assess associations.
Main Results:
- SCFT significantly correlated with BVE and urinary leakage across multiple postoperative time points (p < 0.05).
- Multivariate analysis confirmed SCFT's significant association with BVE and urinary leakage.
- PPFT was not explicitly detailed in its association in the provided results summary.
Conclusions:
- Elevated SCFT is significantly associated with reduced bladder voiding efficiency and increased urinary incontinence post-RARP.
- SCFT shows potential as a valuable predictor for identifying patients at risk of LUTD after RARP.
