Purpose: We present our success rate and complications of delayed anastomotic urethroplasty (DAU) in patients with post-traumatic posterior urethral injury. Materials and Methods: This was a retrospective study of patients aged ≥17 years that underwent DAU for post-traumatic posterior urethral injury during 2010–2014. Stricture length was measured by ascending and descending urethrogram. Success of procedure was considered when the patient was free of stricture-ralated obstruction and needed no further intervention. Primary group includes patients who underwent first time delayed urethroplasty while secondary group included patients who had some sort of urethral manipulation in local hospital. Results were analyzed using unpaired t-test, Chi-square test, binary logistic regression, Kaplan–Meier curves, and log-rank test. Results: Of the 80 male patients, 73 (91.25%) patients underwent primary DAU while 7 (8.75%) patients had secondary DAU. Median age, stricture length, and follow-up were 27.0 ± 12.7, 1.6 ± 0.9, and 3.2 ± 0.9, respectively. Overall, success rate was 83.75% while success rate in primary group was 89.04% and secondary group was only 28.57% (P = 0.0059). Regarding ancillary maneuvers, urethral mobilization alone was done in 29 (36.25%) patients with success rate (72.41%), corporeal body separation in 36 (45%) patients with success rate (91.66%), inferior wedge pubectomy in 13 (16.25%) with success rate (84.61%), supracrural rerouting in 1 (1.25%) with success rate (100%), and abdominoperineal approach in 1 (1.25%) with success rate of 100% (P = 0.193). Patients who had prior urethral manipulation affect the outcome of definitive anastomotic urethroplasty. Conclusion: DAU has durable success rate with less morbidity. Ancillary elaborated maneuvers are frequently needed in patients with complex and elongated post-traumatic posterior urethral defect with successful outcome.
