INTRODUCTION: Meatal and fossa navicularis stricture after hypospadias repair is a challenging condition. A range of management techniques have been applied to treat meatal and fossa navicularis stenosis but, as yet, there is no consensus as to the best method. Open urethroplasty with oral mucosal graft (OMG) has been widely accepted to be the gold standard in repairing the stricture. Generally, the stricture site is approached through a ventral midline, subcoronal, and circumcising incision. A novel effective technique for short segment stricture, transurethral approach to inlay oral mucosal graft urethroplasty would help in avoiding ventral glans, distal penis or ventral urethral incision and can preserve glans of the penis.
METHOD: A 5-year-old boy with mid-shaft hypospadias underwent repair when he was 3 years old. Two months after surgery, he had developed urethral meatal and fossa navicularis stenoses. He is to undergo a novel transurethral approach of inlay OMG urethroplasty. The procedure consisted of transurethral excising the fibrotic tissue at the dorsal site of the stricture urethra. The bougies dilator was used for calibrating the size of the urethra up to 12 Fr. An OMG with a size of 5 × 6 mm was then harvested from the lower lip and applied to cover the defect. A urethral catheter was inserted for 1 week.
RESULT: The outcome was shown to be successful and the patient can void with a good flow after removing the catheter. The graft was well vascularized and the glans was cosmetically acceptable. There was no recurrent stricture after 12 months follow up.
CONCLUSION: This novel technique is simple, effective and may be beneficial as it obviates the need for complex reconstruction. However, this technique would only be feasible in selected patients with suitable conditions of meatal opening and those with a short segment of stricture.
