Analysis of risk factors of urinary incontinence after transurethral resection of the prostate

Objective To investigate the risk factors of urinary incontinence after transurethral resection of the prostate (TURP) and the countermeasures. Methods 263 patients treated with TURP were divided into two groups: 55 patients in the urinary incontinence group, and 208 patients in the no urinary incontinence group, and the clinical data were compared between the two groups. Results The international prostate symptom scale (IPSS) scores and resection proportion of the prostate were respectively (23.25±3.56) and (67.25±5.36)% in the urinary incontinence group, and (18.34±4.05) and (52.15±6.23)% in the no urinary incontinence group (t=8.191, 16.433; P all =0.000). The age, maximum urinary flow rate, duration, volume of prostate, operation time, and postoperative catheterization time were respectively (69.78±6.47) years old, (6.21±2.82) ml/s, (33.54±16.54) months, (65.46±33.52) ml, (70.36±19.21) min, (6.81±0.46) d in the urinary incontinence group; and (70.05±4.82) years old, (5.62±2.63) ml/s, (35.20±17.50) months, (62.65±35.23) ml, (68.21±17.86) min and (6.79±0.52) d respectively in the no urinary incontinence group (t=0.289, 1.457, 0.633, 0.531, 0.781, 0.260; P=0.773, 0.146, 0.528, 0.596, 0.435, 0.795). Of the 55 patients with urinary incontinence, there was one case of true urinary incontinence (1.82%), 25 cases of emergency urinary incontinence (45.45%), and 29 cases of stress urinary incontinence (52.73%). Conclusion Urinary incontinence is a common complication following TURP. High IPSS scores, excessive excision of the prostate and sphincter of the urethra are the main factors leading to postoperative urinary incontinence. The protection of the function urethral and the pelvic floor exercises before and after the operation can reduce the occurrence of urinary incontinence.
