Experience with Tension-free Vaginal Tape (TVT)-SECUR for Female Stress Urinary Incontinence

Objectives: Tension-free vaginal tape (TVT)-SECUR is a technique specifically designed to place a short suburethral mesh sling for the treatment of female stress urinary incontinence (SUI). The aim of the technique is to decrease surgical morbidity. We report our experience of applying this technique on 10 patients. Methods: From June 2007 to July 2007, 10 female patients with SUI underwent TVT-SECUR placement operation. The sling was inserted in a suprapubic direction over the inner surface of pubic bone (U-shaped technique). Nine of the patients underwent videourodynamic study (VUDS). The maximal bladder neck decent distance (MBND) by abdominal straining was determined. We identified intrinsic sphincter deficiency (ISD) as a valsalva leak point pressure lower than 60 cm H2O and hypermobility as MBND more than 2 cm. Results: Two patients had pure ISD, three had hypermobility, and four had both ISD and hypermobility. All patients remained continent for first month after surgery. SUI recurred in five of nine patients at an average of 2.5 months. The recurrence appeared in all three groups of patients. The recurrent SUI was so severe that three patients required repeat surgery using percutaneous prolene tape sling. After surgery, no further SUI was noted in the three patients. During surgery the TVT-SECUR sling was found to have firmly adhered to perivesical tissue rather than to the pubic bone. Conclusion: Our experience shows that the current design of the TVT-SECUR results in unpredictable outcomes. Some placed slings may migrate away from the inner surface of the pubic bone. To act as a reliable “hammock”, the sling must be securely fixed on immobile structures independent from the bladder/urethra.
