Objectives: To evaluate and compare the 2 surgical approaches of urethral reconstruction for management of refractory female urethral strictures (FUS) in a prospective randomized setting. Early surgical reconstruction is becoming the preferred management strategy for recurrent FUS. Reconstructive techniques have been described as using either dorsal (12-o'clock) or ventral approach (6-o'clock), each with their own advantages. To our best knowledge, a direct comparison between the 2 techniques to prospectively compare outcomes hasn't been made.
Methods: We performed a prospective randomized study in a single tertiary care center on a total of 24 patients, randomizing them into 2 groups of 12 patients each. One group underwent dorsal onlay and other underwent ventral onlay urethroplasty. Preoperative, intraoperative and postoperative outcomes were evaluated and compared for the 2 approaches.
Results: There was high success rate (91%) with significant but comparable improvements in flow rates, post void residue and symptomatic outcomes without any major complication. There was 1 recurrence of stricture each in both groups. Important technical differences were noted with easier meatus preservation, lesser bleeding and wider operative field in the ventral approach, while the dorsal approach proving better in distal urethral strictures requiring meatal reconstruction.
Conclusion: Both approaches of urethroplasty present a very promising modality of management of FUS with comparable outcomes but with important technical differences which must be considered to best tailor the approach for each patient.
