Two Cases of Urodynamic Improvements after Mesh Resection in Patients with Protracted Urinary Retention Following Tension-free Vaginal Tape

ABSTRACT

The tension free vaginal tape (TVT) procedure has been developed for female stress urinary incontinence as an effective and durable surgical treatment option under local anesthesia and reportedly has a low complication rate. Recently, two cases of protracted urinary retention following TVT procedure were experienced. Both patients reported normal voiding before the procedure that caused obstruction, and they had urodynamic evidence of obstruction (high pressure/low flow) after TVT procedure. In both patients, the TVT meshes were resected to increase the uroflow rate and decrease the residual urine volume. They resumed normal voiding and continence thereafter and that was evidenced by the urodynamic parameters. The mean maximal flow rate (MFR) increased from 13.0 ml/sec to 28.5 ml/sec and mean residual urine volume (RU) decreased from 284 ml to 65.5 ml after the resection of the TVT sling. So we report our experiences that we could accomplish the urodynamic improvements after mesh resection in two patients with protracted urinary retention following TVT procedure.
