Objectives: Female urethral stricture is a rare disease. Urethroplasty with different techniques using grafts or flaps are successful treatment options. The objective of this study was to present our experience with ventral onlay buccal mucosa graft urethroplasty for the treatment of female urethral stricture disease. Methods: Eight female patients treated with ventral onlay buccal mucosa graft urethroplasty were identified retrospectively. Patient evaluation included physical examination, uroflowmetry with postvoid residual urine measurement, videourodynamics and urethrocystoscopy. Stricture was identified by videourethrography and/or urethrocystoscopy. Urodynamic evidence of stricture was considered as a persistent low maximum flow rate of <12 mL/s combined with detrusor pressure at maximum measured flow rate of >20 cmH2O in the pressure flow study. Results: The mean age was 50.5 ± 4.14 years. Stricture etiology was idiopathic (62.5%) or iatrogenic (37.5%). Two patients (25%) had undergone prior urethral dilations before buccal mucosa graft urethroplasty. Mean stricture length was 1.62 ± 0.44 cm. Stricture location was as follows: four distal urethra (50%), two mid‐distal (25%) and two mid‐urethra (25%). The mean postoperative follow‐up period was 16.37 ± 5.75 months, and the during follow‐up success rate was 100%. No complication, such as incontinence or vaginal fistula, was noted, except dyspareunia developed in one patient (12.5%). Conclusions: Ventral onlay buccal mucosa graft urethroplasty is a safe and effective treatment option for female urethral stricture. Unnecessary dilation should not be carried out and buccal mucosa graft urethroplasty in expert centers should be recommended to these patients. [ABSTRACT FROM AUTHOR]
