Popis: Background: Dorsal or ventral single layer repair can be impractical when there is an inadequate strip of urethra. Staged urethroplasty and non-transecting bilayer substitution urethroplasty are the other alternatives. Objectives: To assess the safety and outcome of non-transecting dorsal onlay and ventral inlay buccal mucosal substitution urethroplasty technique. Method: Between January 2014 and December 2018, 21 patients underwent non-transecting, double-layer, buccal mucosal urethroplasty for inflammatory bulbar urethral strictures. Four weeks after surgery, foley catheters were removed and voiding trial was given. Clinical examination and uroflowmetry (UFM) were done at 1, 3, and 6 months after surgery. Annual follow-up with flow rate and post-void residual assessment were also recorded. Failure was defined as a condition when there was flow rate deterioration (Results: The mean age was 49.5 years. There was no significant difference in comorbidities among the patients. The mean duration of operative time was 259 min. The mean blood loss was 190 mL. The follow-up duration ranged from 12 to 66 months. The average length of stricture was 3.9 cm. The mean diameter of stricture segment was 1.96 mm. Comparison of UFM trend during follow-up was statistically significant (p = 0.05). One patient had Clavien-dindo grade 1, while 2 patients had grade 3b complications. Two patients had soft anastomotic site stricture and were treated successfully with endoscopic internal urethrotomy. The success rate was 90.47%. Conclusions: Non-transecting bilayer substitution urethroplasty is safe and has better short-term outcome in case of obliterative inflammatory urethral strictures.
