Risk factors analysis for urinary incontinence after radical prostatectomy

Objective To identify the risk factors of urinary incontinence after laparoscopic radical prostatectomy. Methods In the retrospective study, 54 patients who received laparoscopic radical prostatectomy in our hospital from January 2015 to January 2018 were reviewed. The correlation analysis of the clinical characteristics and postoperative urinary incontinence at the third month was performed. Results Postoperative urinary incontinence occurred in 25 cases (46.3%) of all these patients. The results of the one-way ANOVA on the postoperative urinary incontinence group and the non postoperative urinary incontinence group showed that there were statistically significant differences in patients’ age, preoperative prostate specific antigen (PSA), prostate volume, preoperative urinary bladder residual urine volume, preoperative urinary incontinence, urinary tract infection (P<0.05); there was no significant correlation between the postoperative urinary incontinence and BMI (body mass index), preoperative pathological Gleason score, history of transurethral resection of the prostate, length of surgery, postoperative leucocyte count, postoperative serum albumin, retention time of urethral catheter. The multivariate analysis showed that, age (OR=0.842, 95%CI=0.712-0.997, P=0.046), preoperative urinary incontinence (OR=7.884, 95%CI=2.366-45.516, P=0.021), urinary tract infection (OR=5.139, 95%CI=1.062-24.861, P=0.042) were significantly correlated with the development of the postoperative urinary incontinence. Conclusion The incidence of postoperative urinary incontinence at the third month after laparoscopic radical prostatectomy was significantly correlated with increasing age, preoperative urinary incontinence, and urinary tract infection. Key words: Radical prostatectomy; Urinary incontinence; Urinary tract infection
