Abstract

Purpose

There is a growing interest in reconstructive urology and female urethroplasty. We aimed to report our experience in ventral-onlay buccal mucosa graft (BMG) urethroplasty supported with Martius flap (MF) in treating female urethral stricture disease.

Methods

We retrospectively evaluated data of 18 female patients (ages 35–78) who were diagnosed with urethral stricture disease and underwent ventral-onlay BMG urethroplasty supported with MF by single surgeon in a tertiary referral centre between February 2019 and October 2022. Detailed history, international prostate symptom score (IPSS), pelvic examination, urine flow rate (rate and pattern), post void residual (PVR), storage and voiding phase urodynamic study, and voiding cystourethrography were recorded. At the last visit; the number of urethral dilatations before urethroplasty, time from urethral dilation to urethroplasty, hospital stay, urethral catheterization time, postoperative IPSS, PVR and uroflowmetry values were recorded.

Results

The presenting symptoms were obstructive voiding symptoms in 16 patients. While the mean number of urethral dilatation was 2.11 ± 1.93 (1–7), the mean time from dilatation to urethroplasty was 5.83 ± 5.00 (1–19 months) months. Maximum flow rate increased from 8.36 ± 3.26 ml/sec in preoperative uroflowmetry to 21.45 ± 5.27 ml/sec at the last follow-up (p < 0.001). Post-void residual urine (PVR) decreased from preoperative mean 116.66 ± 105.88 cc to 26.94 ± 22.69 cc postoperatively (p < 0.004). None of the patients developed stricture recurrence, incontinence or vaginal fistula until the last follow-up. The mean follow-up period was 17.28 ± 11.65 (1–35) months.

Conclusions

A ventral-onlay BMG urethroplasty supported with MF represents an effective and reproducible treatment option for FUS in the present study.
