There are various augmentation urethroplasty options available for the treatment of recurrent urethral strictures. This study presents the buccal mucosa graft combined with Kulkarni's dorsal urethroplasty technique and emphasizes its efficacy in treating recurrent urethral strictures.

In our study, a 34-year-old male patient with a history of catheter placement following a traffic accident, who later developed a urethral stricture, was evaluated. The patient had undergone five closed dilation procedures and was found to have a stricture in the penile urethra on retrograde urethrogram. Preoperative evaluation revealed a uroflow measurement of 123 ml/s, a peak flow rate of 3.5 seconds, a low flow rate of 1.5 ml/s, and a post-void residual (PVR) urine volume of 100 cc. The uroflow trace showed findings consistent with a stricture. Based on the patient's history, physical examination, and imaging findings, the decision was made to begin the operation with a perineal vertical incision. An endoscopic approach was employed via a median incision in the high lithotomy position. A stricture approximately 2 cm proximal to the external meatus of the penile urethra, measuring around 5 cm in length, was identified. After the stricture was bypassed, a smooth mucosal surface and normal-caliber urethra were observed. The patient underwent urethroplasty according to Kulkarni's dorsolateral technique using a buccal mucosa graft.

The duration of the surgery was recorded as 120 minutes, with a blood loss of 50 cc. The patient was discharged with a catheter on the 4th postoperative day with appropriate recommendations.

In the treatment of recurrent urethral strictures, the buccal mucosa graft combined with Kulkarni's dorsolateral urethroplasty technique can be considered an effective and safe option. This technique offers successful outcomes, particularly in the management of strictures.
