Modified cystoscopy-assisted laparoscopic Y-V plasty for recalcitrant bladder neck contracture

Background and aim:Recalcitrant bladder neck contracture (BNC) is a common complication after transurethral resection of the prostate. Our aim was to show the outcomes of a modified cystoscopy-assisted laparoscopic Y-V plasty for BNC treatments. Material and methods:We retrospectively evaluated a series of 27 patients who underwent a modified cystoscopy-assisted laparoscopic Y-V plasty for recalcitrant BNC from January 2017 to September 2019. Urinary flow rate, international prostate symptom score (IPSS), international index of erectile function-5 (IIEF-5) and bladder urethral examination by cystoscopy were performed preoperatively and postoperatively, respectively. Results:All patients underwent the procedure successfully and no serious complication occurred. The median surgery time was 68.6 min without massive bleeding. The median follow-up time was 14.2 months and no patients had urinary incontinence. The maximum urine flow rate 3 months after surgery was significantly higher than prior to surgery (17.7 +/- 2.1 ml/s vs. 8.2 +/- 1.2 ml/s,p < 0.05). The IPSS was significantly decreased compared with the preoperative score (5.7 +/- 2.3 vs. 19.2 +/- 1.4,p < 0.05). The cystoscopy showed a wide bladder neck and the survival bladder flap in prostate urethral 3 months postoperatively in 92.6% (25/27) patients. Conclusions:The modified cystoscopy-assisted laparoscopic Y-V plasty is a feasible and effective technique for recalcitrant BNC treatment.

Automated summary

This study retrospectively evaluated the outcomes of a modified cystoscopy-assisted laparoscopic Y-V plasty in 27 patients with recalcitrant bladder neck contracture (BNC). The results showed that the modified procedure was a feasible and effective treatment technique, with improvements in urinary flow rate and symptom scores after surgery.
