    Abstract:
    OBJECTIVE: The purpose of this study was to analyze the risk factors for predicting urethral stricture and urinary incontinence after transurethral resection of the prostate (TURP). METHODS: A retrospective study of 261 patients admitted from October 2018 to October 2022 who received TURP for benign prostatic hyperplasia (BPH) with complete postoperative follow-up data of at least 6 months. Patients were divided into urethral stricture group (n =18), non-urethral stricture group (n =243), urinary incontinence group (n = 12) and non-urethral incontinence group (n = 249) according to the presence of urethral stricture and urinary incontinence. Compared two groups of patient's age, course of the disease, hypertension, diabetes mellitus, IPSS score, prostate volume, maximum urine flow rate, whether preoperative urinary retention, total prostate specific antigen levels and whether preoperative status, placing a urinary catheter preoperative whether merger urinary tract infection, operative time, postoperative time, postoperative urine tube drawing time placing a urinary catheter, etc. Univariate and multivariate Logistic regression analyses were used to screen for independent predictors. RESULTS: The incidence of urethral stricture and urinary incontinence after TURP was 6.9% and 4.6%, respectively. Multivariate logistic regression analysis showed that diabetes mellitus (OR = 9.526, 95%CI: 2.824－32.127, P= 0.000); Preoperative urethral infection (OR = 6.500, 95%CI: 1.513－27.925, P = 0.012); Postoperative indwelling catheter time (OR = 2.063, 95%CI: 1.181－3.601, P = 0.011) was an independent risk factor for postoperative urethral stricture. Age (OR = 1.21, 95%CI: 1.027－1.425, P = 0.023); Diabetes mellitus (OR = 37.515, 95%CI: 2.615－538.170, P = 0.008); Postoperative indwelling catheter time (OR = 20.806, 95%CI: 3.090－140.080, P = 0.002) was an independent risk factor for postoperative urinary incontinence. CONCLUSIONS: Urethral stricture and urinary incontinence are common complications after TURP. Diabetes, preoperative urethral infection, and postoperative catheter indwelling time are independent risk factors for urethral stricture after TURP. Age, diabetes mellitus and postoperative catheter indwelling time were independent risk factors for postoperative urinary incontinence. Diabetes mellitus and postoperative catheter indwelling were common and independent risk factors for urethral stricture and urinary incontinence after TURP.
