    Abstract:
    BACKGROUND: Non-traumatic obliterative bulbar urethral stricture with residual urethral lumen below 3 Fr is a challenging surgical scenario for reconstructive surgeons, because either anastomotic or single augmentation urethroplasty is not an option. OBJECTIVES: To describe our double-face buccal mucosa graft (BMG) urethroplasty with dorsal onlay and ventral inlay relying on the vessels and nerve-sparing technique of Kulkarni's one-side dissection. METHODS: We retrospectively reviewed a prospectively maintained database of patients with non-traumatic obliterative bulbar urethral strictures who underwent double-face bulbar urethroplasty with one-side dissection and dorsal onlay plus ventral inlay BMG. Patient demographics, clinical data, and follow-up were analyzed. RESULTS: A total of 59 patients underwent double-face urethroplasty with dorsal approach. The median age was 37 years (IQR 27-49) and the median stricture length was 5 cm (IQR 3.75-6). No patients had immediate post-operative complications. The overall success rate was 88% with a median follow-up of 30.9 months (IQR 16.9-44.2). Two patients were treated with DVIU, and two patients with open urethral surgery. One patient developed erectile dysfunction after surgery. Age, etiology, stenosis length and previous treatment were not factors related to surgical failure. CONCLUSION: Our preliminary albeit encouraging results showed that this approach was feasible in all patients and with negligible perioperative complications. Success rate was 88%. We did not find any factors related to surgical failure. Our dorsal double-face augmented urethroplasty may be a valid alternative to the Palminteri's ventral double-face urethroplasty, especially in those patients with mid-distal bulbar or peno-bulbar urethral strictures.
