Objectives: Stress incontinence is the most common type of urinary incontinence in females. Recently, the gold standard treatment is mid-urethral tapes, however their efficacy is questioned in intrinsic sphincter deficiency (ISD). In our study, we try to adjust the tension applied during transobturator tapes (TOT) to evaluate its effectiveness in ISD, in order to prevent obstruction or failure and persistence of stress urinary incontinence. Materials and Methods: This study was prospectively conducted on eighty female patients having ISD, presenting at the Urology Departments in Alexandria and Minia University Hospitals. The patients were randomly assigned to two groups, with Group I including forty patients, who underwent TOT using tension-free technique, and Group II including forty patients using our new tension adjustment technique under saddle anesthesia. Patients filled the International Continence Questionnaire and Urinary Distress Inventory and did pressure flow study pre- and postoperatively. Postoperatively, the patients filled Patient Global Impression of Improvement and underwent translabial ultrasound (U/S) to estimate the distance between the tape and the urethra. Results: In Group I, 70% of the patients were cured with mean Valsalva leak point pressure (VLPP) of 51.43 ± 3.39 preoperatively, 20% were not improved, and 10% were improved with a mean VLPP of 44.5 ± 3.54 preoperatively, which increased to 86 ± 4.24 postoperatively. In Group II, 95% of the patients were cured with a mean VLPP of 50.74 cmH2O ± 6.56 preoperatively and 5% improved but not cured with a mean VLPP of 31 cmH2O preoperatively, which increased to 127 cmH2O at a bladder capacity of 400 ml. All patients in both groups underwent translabial U/S 6 months postoperatively. The distance between the mid-tape and the outer urethra measured by translabial US showed no significant difference between the two studied groups. Conclusion: Performing TOT using our tensioned proposed technique in ISD seems to be effective and with low morbidity. Intraoperative adjustment of tension using Valsalva maneuver under saddle anesthesia gives better outcomes than the conventional tension-free technique. The concept of tension-free vaginal tape should be challenged.
