Abstract:
Objective:To investigated the efficacy and safety of transurethral bladder neck incision and laparoscopic modified bladder neck Y-V plasty in the treatment of bladder neck contracture (BNC)after transurethral resection of prostate (TURP).Methods:The clinical data of 57 patients with BNC after TURP who were treated in the Department of Urology, Sixth People's Hospital, Shanghai Jiaotong University School of Medicine from January 2013 to December 2022 were retrospectively analyzed.And the patients were divided into two groups based on the different surgical approaches. There were 22 cases in the transurethral bladder neck incision group, with an average age of (73.75±7.62) years and the preoperative urinary flow Q max of (3.92±2.73) ml/s. The preoperative International Prostate Symptom Score (IPSS) was (26.92±3.34) points, and the quality of life (QOL) score was (4.83±0.72) points. There were 35 cases in laparoscopic modified bladder neck Y-V plasty group, with an average age of (68.57±9.31) years and the preoperative urinary flow Q max of (2.56±1.27)ml/s. The preoperative IPSS was (27.08±3.06) points, and the QOL score was (5.08±0.84) points. The patients underwent transurethral bladder neck incision: Scar tissue was incised at 3, 9, and 12 o'clock in the bladder neck, and the incision depth reached the external fat of the bladder neck at 3 and 9 o'clock. Patients with significantly elevated bladder neck were treated with plasma electrosurgical resection to remove scar tissue. The patients underwent laparoscopic modified bladder neck Y-V plasty: After proper exposition of the bladder neck, the scar tissue was excised. the anterior bladder wall was incised in an inverted Y-shaped manner, the apex of the V-shaped flap was sutured to the distal urethrotomy to create a widened bladder neck. The postoperative urinary flow Q max, IPSS, and QOL of the two groups were compared. Results:All patients underwent surgeries successfully, with a one-time success rate of 94.3% (33/35) in the laparoscopic modified bladder neck Y-V plasty group, which was higher than the one-time success rate of 68.2% (15/22) in the transurethral bladder neck incision group( P<0.01). There were statistically significant difference in operation time [(31.75±12.81)min vs. (68.57±22.36)min] and postoperative hospital stay [(1.73±0.94)d vs. (5.17±2.12)d] between the transurethral bladder neck incision group and the laparoscopic modified bladder neck Y-V plasty group ( P<0.05). The median follow-up period was 12.6 (7.3, 27.8) months. The IPSS of the transurethral bladder neck incision group and the laparoscopic modified bladder neck Y-V plasty group were (9.92±2.56) points and (7.16±2.21) points, respectively. The QOL was (2.76±1.24) points and (1.31±0.95) points, respectively. The urinary flow Q max at 6 months after operation was (15.13±4.68)ml/s and (19.96±4.17)ml/s, respectively. There was statistical significance( P<0.05). Conclusions:Both laparoscopic modified bladder neck Y-V plasty and transurethral bladder neck incision are safe and effective in the treatment of BNC after TURP, and laparoscopic modified bladder neck Y-V plasty has a better clinical therapeutic effect.
