  ABSTRACT: To evaluate the various operative details of strictures of the posterior urethra that are essential for a successful result. The clinical data of 191 patients with posterior urethral strictures or distraction defects from January 1990 to January 2006 were analyzed retrospectively. All patients underwent a retrograde and voiding urethrogram, 62 patients had urethral ultrasonography, 48 patients had urethroscopy, 3 patients had MRI. Repair was performed with a simple anastomosis after urethral mobilization in 66 patients, separation of the corporeal bodies in 48 patients, separation of the corporeal bodies and inferior pubectomy in 30 patients, transpubic anastomosis in 18 patients, pull-through operation in 3 patients, and optical urethrotomy in 26 patients. Followup ranged from 6 to 48 months. The mean stricture length was 3.6 cm (range from 1.5 to 8.0 cm). Posterior urethral strictures is in 31 (16%), posterior distraction defects is in 160 (84%), of which the length of the distraction defects < 3 cm is in 102 (53.4%), and the the length of the distraction defects > 3 cm is in 58 (30.6%). The overall successful results (Qmax > 15 ml/s) after operation was 84.3%. Optical urethrotomy was 69%, the successful results with anastomotic urethroplasty were 97% with a simple anastomosis; 79% with separation of the corporeal bodies; 80% with separation of the corporeal bodies and inferior pubectomy; 83% with transpubic anastomosis; and 67% with pull-through operation. The anastomotic urethroplasty is better than the optical urethrotomy, the length of the strictures or distraction defect which is lower than 3 cm is much more successfully corrected.

  ABSTRACT: PurposeWe constructed a reliable continent tube that is easy to catheterize and surgically simple.Materials and MethodsEight patients with bladder cancer underwent a procedure in which ileal segment was tapered as an efferent tube, of which a part was placed between the back surface of the rectus muscle and the ileal pouch wall. The internal orifice of the tapered ileum was anastomosed to the ileal pouch and its external orifice was anastomosed to the umbilicus. Urodynamic and radiological studies were done postoperatively in 7 cases.ResultsThe stoma was easily catheterized with a 16Fr catheter in all cases. One patient died of heart disease 55 days postoperatively, while 6 of the remaining 7 were completely continent day and night. Urodynamic study of the efferent tubes showed that maximum close pressure with the pouch full was significantly higher than with the pouch empty (p <0.001). Retrograde radiography of the efferent tubes demonstrated perfect canalization without stenosis.ConclusionsThis study indicates that the continent mechanism of tapered ileum may be greatly enhanced by fixing it between the abdominal and pouch walls. This maneuver also provides easy catheterization and surgical simplicity.
