Purpose: Complete urethral mobilization may endanger the lateral vascularity of the urethra in buccal mucosal graft (BMG) urethroplasty in stricture urethral disease. The present study aimed to evaluate the outcomes of BMG urethroplasty by dorsolateral onlay technique in patients with anterior urethral stricture. Materials and Methods: This was a prospective interventional study conducted at the Department of Urology at PSG Institute of Medical Sciences and Research between January 2015 and December 2018. Patients diagnosed with anterior urethral stricture who underwent dorsolateral onlay urethroplasty were included in this study. Results were considered satisfactory with the Qmax between 8 mL/s and 15 mL/s. Failed outcome was defined as persistent lower urinary tract symptoms, stricture on retrograde urethrogram, Qmax <8 mL/s, and requiring repeated urethra intervention. Results: A total of 54 patients underwent BMG urethroplasty by dorsolateral onlay graft with a mean age of 47.6 years. The patients with a range of stricture length 3–14 cm were included in this study. Short-term success rate (Qmax >15 mL/s) was achieved in 42 patients, while satisfactory results (Qmax 8–15 mL/s) were observed in nine patients and failure (Qmax <8 mL/s) occurred in three patients. Oral and perineal complications were treated conservatively with oral antibiotics and analgesia. None of the patients in this study had a postoperative perineal hematoma, graft infection, and scrotal swelling. Conclusion: Overall observations suggest that dorsolateral onlay BMG urethroplasty with unilateral urethral mobilization for an anterior urethral stricture is a feasible and effective option with favorable outcomes.
