OBJECTIVES: To compare the feasibility and outcomes of non-transecting anastomotic urethroplasty (NTAU) with excision and primary anastomosis (EPA) in the management of non-traumatic posterior urethral stenosis (PUS).
METHODS: We retrospectively reviewed 30 male patients who underwent anastomotic urethroplasty for non-traumatic PUS between October 2013 and July 2024. EPA was performed in 15, and NTAU in 15. Surgical success was defined as the absence of recurrent stenosis on cystourethroscopy without additional intervention. Patient-reported outcomes, including lower urinary tract symptoms (LUTS), continence status, and quality of life measures, were assessed using validated questionnaires.
RESULTS: The surgical success rate was 100% for NTAU and 86.7% for EPA (p = 0.14). Operative time was significantly shorter in the NTAU group (158 vs. 199 min, p = 0.04). The proportion of pad-free patients was significantly higher in the NTAU group (p = 0.01). Among 14 patients with preserved bladder neck function, 8 (80.0%) in the NTAU group achieved pad-free status, whereas none in the EPA group did (p = 0.006). Both groups showed significant improvements in LUTS-specific quality of life (p = 0.03 for NTAU, p = 0.0006 for EPA) with no significant differences between groups (p = 0.78). Changes in Sexual Health Inventory for Men (SHIM) scores were comparable between groups (p = 0.41).
CONCLUSIONS: NTAU demonstrated comparable surgical success rates to EPA with shorter operative times and better continence outcomes, particularly in patients with preserved bladder neck function. These preliminary results suggest that NTAU is a feasible alternative to EPA for non-traumatic PUS, though longer follow-up and larger studies are needed to confirm these findings.
