Abstract:
Objective To evaluate the outcome of various operative selection for treating posterior urethral stricture via transperineal approach.Methods The clinical data of 5 000 patients with posterior urethral stricture or obstruction from January 1990 to January 2017 were analyzed retrospectively.All patients were male.The age of those patients ranged from 18 months to 77 years old,mean 36.6 years old.Pelvic crush inju.ry caused by car accident occurred in 2010 cases.Falling injury occurred in 1680 cases.Pelvic compressed injury occurred in 1 310 cases.Accompanied visceral damage occurred in 2 590 cases,including the liver and spleen rupture in 920 cases,lower limb fracture in 1 200 cases.2 200 cases accepted urethral realignment under emergency.2 800 cases were treated with pubic cystostomy.All patients were undergone a retrograde and voiding urethrogram.562 patients accepted urethral ultrasongraphy,and 2 448 patients accepted urethroscopy.204 patients accepted MRI examination.The mean stricture length was 4.3 cm,ranged from 1.8 to 8.6 cm.Posterior urethral stricture was found in 810(16.2％)cases.The complete olstruction of posterior urethra was found in 4 190 (83.8％) cases,of which the length of the distraction defects≤3 cm was found in 2 650(53.0％) cases and the length of the distraction defects ＞ 3 cm was found in 1 540 (30.8％) cases.Bladder calculi was found in 2 300 cases.The perineal fistula or abscess was noticed in 290 cases.False passage was found in 460 cases.Urethra rectum fistula was found in 160 cases.Bladder neck open was noticed in 89 cases.Repairing was performed via a simple anastomosis after urethral mobilization in 1 700 patients,via separation of the corporeal bodies in 1 302 patients,via separation of the corporeal bodies and inferior pubectomy in 1 910 patients and via scrotal skin flap urethroplasty in 68 patients.Pull-through operation was performed in 20 patients.Results Postoperative follow-up were conducted from 6 to 72 months with average duration of 23 months.The overall successive results after operation was 92.2％(4 608/5 000),which the Q was more than 15 ml/s.The successive rate of urethroplasty were 97％(1 649/1 700) in simple anastomosis;93％ (1 211/1 302) in separation of the corporeal bodies;88％ (1 680/1 910) in separation of the corporeal bodies and inferior puberctomy;78％ (53/68) in scrotal skin flap urethroplasty and 83％ (15/18) in pull-through operation.The successive rate were 96％ (778/810) in posterior urethral stricture;95％ (2 517/2 650)in distraction with the length of obstruction less than 3 cm and 86％ (1 324/1 540) in distraction with the length of obstruction more than 3 cm.Conclusions The transperineal end to end anastomotic urethroplasty has become the first-line therapy for posterior urethral atresia.The length of the strictures or distraction defect which is lower than 3 cm is much more successfully corrected.
