术前盆底肌电生理参数对前列腺癌根治性切除术后早期尿失禁的预测价值
Predictive value of preoperative pelvic floor electrophysiological parameters on early urinary incontinence following radical prostatectomy
摘要
Abstract
Objective:To explore the predictive value of preoperative pelvic floor electromyography(EMG)parameters for the risk of urinary incontinence after prostate cancer surgery.Methods:This study retrospectively analyzed the medical records of 271 patients who underwent radical prostatectomy in the urology department of Peking University First Hospital from January 2020 to October 2022.The data included patient age,body mass index(BMI),international prostate symptom score(IPSS),prostate-specific antigen(PSA)levels,Gleason score,type of surgery,urethral reconstruction,lymph node dis-section,nerve preservation,catheterization duration,D'Amico risk classification,American Society of Anesthesiologists(ASA)score,Charlson comorbidity index,postoperative duration,prostate volume,and pelvic floor EMG parameters(pre-resting mean,fast muscle mean,and slow muscle mean scores).Independent risk factors affecting early postoperative urinary incontinence were identified through multiva-riate Logistic regression analysis.The predictive efficacy of pelvic floor EMG results was evaluated by cal-culating the area under the receiver operating characteristic(ROC)curve,and the optimal threshold for early postoperative urinary incontinence was determined based on the Youden index and clinical signifi-cance.Results:The study included 271 prostate cancer patients,with an 81.9％rate of voluntary urinary control post-surgery.The median score for fast pelvic floor muscles was 23.5(18.2,31.6),and for slow muscles,it was 12.5(9.6,17.3).Among the patients,179(66.1％)did not preserve nerves,and 110(40.6％)underwent urethral reconstruction.Advanced age and low fast muscle scores were identified as independent risk factors for urinary incontinence.Patients aged ≤60 had 5.482 times the voluntary urinary control rate compared with those aged ≥70(95％CI:1.532-19.617,P＜0.05).There was a significant correlation between fast muscle scores and urinary incontinence recovery(OR=1.209,95％CI:1.132-1.291,P＜0.05).When the optimal threshold for preoperative fast muscle score was set at 18.5,the ROC sensitivity and specificity were 80.6％and 61.2％,respectively.Con-clusion:Preoperative pelvic floor EMG parameters show good predictive accuracy and clinical applicabili-ty for the risk of urinary incontinence after prostate cancer surgery.These parameters can be used for ear-ly identification of urinary incontinence risk,with age and fast muscle scores being important predictors.关键词
