Abstract

INTRODUCTION AND HYPOTHESIS: 

To present the surgical details and the outcomes of our modified ventral onlay buccal mucosal graft (BMG) urethroplasty technique in female patients with urethral strictures.

METHODS: 

We included the first seven female patients who had BMG urethroplasty between January 2015 and April 2019 and had at least 6 months of follow-up. Patient age, stricture length, comorbidities, number of previous treatments, pre- and postoperative uroflowmetry data, and post-void residual volumes were recorded.

RESULTS: 

The mean patient age was 56.7 (44-80) years. The mean stricture length was 3.1 (2-4) cm. The mean postoperative follow-up time was 23 (7-48) months. The preoperative mean maximal flow rate (Qmax) was 5.1 (3.2-9.5) ml/s and post-void residual urine volume (PVR) was 84.4 (37-158) ml. At the 3rd month after surgery, mean Qmax was 31.8 (24.7-36.2) ml/s, and PVR volume was 7.1 (0-16) ml. Three patients had the postoperative 2-year follow-up, and 12th and 24th month mean Qmax values were 28 (23.6-33.2) ml/s and 28.5 (24.1-31.1) ml/s, respectively. The mean operation time was 63.8 (55-113) min. We did not observe any infection, vaginal erosion, urinary incontinence, or oral discomfort due to graft harvesting postoperatively.

CONCLUSION: 

Female urethroplasty provides high cure rates and should be performed in case of recurrent FUS. The early and medium-term results of our modified new technique indicated that it might be used as a simple alternative to current techniques. In all of our patients, it significantly increased the flow rate and reduced PVR without any significant complications.Uretrplastia
