Role of Dorsalonlay full thickness vaginalgraft urethroplasty in the management of stricture urethra in females

Abstract

Introduction: Female urethral stricture is an under diagnosed cause of bladder outlet obstruction in females. The possible aetiology may be idiopathic, infection, difficult catheterisation with subsequent fibrosis, prior urethral surgery or trauma. We present our technique and results of dorsal onlay full thickness vaginal graft urethroplasty for stricture urethra in females. Materials and Methods: A prospective study was performed on 14 female patients with stricture urethra who underwent dorsal onlay vaginal graft urethroplasty from February 2013 to February 2015. All thepatients had previously undergone multiple dilatations. The preoperative evaluation included detailed voiding history, local examination, uroflowmetry, calibration with 10 Fr Foley’s catheter and micturating cystourethrogram (MCUG). Results: Mean age of presentation was 46.5 years. Mean Qmax improved from 6.9 to 24.2 ml/s and mean residual volume decreased from 161 to 17.3 ml. Mean operative time was 81.4 min and mean hospital stay was 3.8 days. Mean duration of follow-up was 18 months (6 months to 2 years). None of the patient was incontinent. Conclusion: Dorsal onlay vaginal graft urethroplasty could be considered as an effective way to treat female urethral strictures.
