Evaluation of the Eeffectiveness of Two Surgical Methods of Tension-free Vaginal Tape (Transversal and Longitudinal Incision of the Vagina) in Women with Stress Urinary Incontinence

The aim of this study was to determine the effectiveness of two surgical methods of Tension-free Vaginal Tape (TVT) (transversal and longitudinal incision of the vagina) on stress urinary incontinence in women referred to Imam Reza Hospital during 2012–2019. The present study was a clinical trial study which was conducted on 138 women with stress urinary incontinence. TVT surgery. Patients were randomly divided into two groups with transversal (n = 69) and longitudinal incision (n = 69) based on purposive sampling. All patients before surgery underwent cystoscopy, Marshall test and cough stress test, urinary tract mobility test and, if necessary, urodynamic test, pelvic examination and post-void residual (PVR) urine test and completed the incontinence impact questionnaire-7 (IIQ-7). Then, mesh survival at 60 months after surgery was assessed by trans-libial ultrasonography. Statistical analysis was conducted by SPSS 24 (Chi-square test, Fisher's exact test).There was no statistically significant difference between the two groups with longitudinal and transverse incisions in terms of mean age, duration of surgery and the amount of urine remaining in the bladder before and after surgery (P-Value > 0.05). The recovery rate was higher in the transverse incision group compared to the longitudinal incision group and this difference was statistically significant (P-Value = 0.023). Also, the mesh retention rate was higher in the middle position of the duct in the transverse incision group .TVT surgery with transversal incision of the vagina can be effective and safe in treating stress urinary incontinence of women.
