Effect of intracavitary enucleation on urge incontinence in transurethral prostatectomy

【Objective】To investigate the effect of intracavitary enucleation in transurethral prostatectomy to urge incontinence after operation. 【Methods】112 cases of benign prostatic hyperplasia, were divided into two groups with concurrent control, 67 of them underwent transurethral prostatectomy with along-shear management, 45 of them underwent transurethral prostatectomy with intracavitary enucleation. The incidence rate of temporary incontinence in two groups were analyzed with chi-squared test. The functional urethral length in preoperation and postoperation, the occurrence time and recovery time of temporary incontinence symptoms were analyzed with independent sample t test. 【Results】The incidence rate of temporary incontinence was higher than, the functional urethral length was less, the occurrence time was faster and the recovery time was slower in the intracavitary enucleation group than in the along-shear management group. The above differences were statistically significant (P 0.01 or P 0.05). 【Conclusions】Intracavitary enucleation in transurethral prostatectomy can lead to the increase of urge incontinence, which may be relative to the decrease of functional urethral length and urethra closure areas.
