Abstract

Introduction
The most widely accepted definition of female urethral stricture (FUS) is a symptomatic, anatomical narrowing of the urethra based on a failure of catheterization, urethral calibration, visual inspection, endoscopy or radiography. Thus it is a rare condition, its diagnostic and treatment are challenging for the reconstructive urologist.
Design
We present the case of a 47 year-old female, with a urethral stricture due to vulvar lichen sclerosus inducing incomplete bladder emptying and recurrent urinary tract infections. We decided to use lingual mucosa because the buccal mucosa was also affected by the lichen. 
The aim of this video was to describe the procedure of dorsal onlay lingual mucosa graft urethroplasty.
Results
The operating time was 70 minutes. The procedure began with the injection of adrenaline and xylocaine serum. An inverted U incision was performed anterior to the urethra. Dissection was carried out in the plane developed between the underlying urethra and overlying clitoral cavernous tissue. A dorsal urethrotomy was performed at a 12 o’ clock position until healthy proximal urethra was reached. 
The lingual mucosa graft was harvested after having identified the Wharton’s duct orifices. The graft edges were incised using a scalpel and the graft was removed using sharp scissors. The graft was maturated by removing the fat and muscular tissue of its non-mucosal side. 
The graft was sutured to the margins of the urethral plate. The distal part of the graft was quilted to the above periurethral flap in order to recreate the ventral aspect of the urethral meatus. A 18FR silicone catheter was placed carefully at the end of the procedure. No peri operative complication occurred. The patient was discharged two days after surgery and did not have recurrence of stricture after 6 months.
Conclusion
Dorsal onlay lingual mucosa graft urethroplasty is a feasible option for female urethral stricture with satisfactory postoperative outcomes.
