Double Tension Adjustments with Novel Modification on Tension-Free Vaginal Tape.

To evaluate the results of novel modifications on tension- free vaginal tape (TVT) for the treatment of women with stress urinary incontinence (SUI). Sixteen female patients (average age 49.29 years, range: 31-78) who underwent anti-incontinence surgery to correct their SUI in the period between June 2010 and August 2014 were included in the study. In situ anterior vaginal wall sling was prepared, and monofilament polypropylene tape passed below the in situ-sling and standard TVT procedure was performed. Both ends of the mesh in the suprapubic region were labeled with Vicryl sutures and left outside the wound. The middle of the mesh in the vaginal region were labeled with similar suture and left outside the vagina. Foley catheter was removed on the third postoperative day. The average period of follow-up was 8 months (range: 5-17). All patients benefited from the surgery; 15 (94%) of them completely cured and one patient clinically improved. Urinary retention was observed in one patient where the tension of the tape was reduced using adjustment sutures. No vaginal mesh erosion was detected during the gynecological examination postoperatively. No significant post-voiding residue was detected after catheter removal. This technique gives feasible option to adjust the tension of the mesh in the early post-operative period in case of urinary retention. Presence of intervening in situ sling reduces the risk of vaginal erosions. Long-term success is expected because dislocation of the mid-urethral sling is less likely.

Prospective randomized trial of TVT and TOT as primary treatment for female stress urinary incontinence with or without pelvic organ prolapse in Southeast China

To compare the outcomes of tension- free vaginal tape (TVT) and transobturator tape (TOT) in the treatment of female stress urinary incontinence with or without concomitant pelvic organ prolapse (POP). One hundred and forty patients with SUI were randomly allocated to TVT (n=70) or TOT (n=70). The objective outcomes were assessed with a stress test, 1-h pad test. Subjective outcomes were assessed with UDI-6/(IIQ-7) questionnaires. The surgical outcomes revealed no significant difference between TVT and TOT surgical route. Both the subjective and objective cure rates were 91.4% in the TOT group, while 90 and 92.8% in the TVT group, respectively. The results showed the association to pelvic floor surgical techniques did not diminish a year later. TOT procedure has a shorter operative time for patients without concomitant surgery. The efficacy and safety of TVT procedure were similar to that of TOT procedure for female stress urinary incontinence with or without concomitant POP.

Mechanical properties of urogynecologic implant materials.

Synthetic suburethral slings have recently become popular despite the risk of erosion commonly associated with synthetic implants. Some of these materials seem to have unexpectedly low erosion rates. Based on the hypothesis that erosion is due, in part, to biomechanical properties, we undertook an in vitro study. The biomechanical properties of eight non-resorbable synthetic implant materials, stiffness (slope, N/mm) and peak load (N) were determined from load vs. displacement curves. Open-weave Prolene mesh showed unique biomechanical properties compared to other tested materials. The tension- free vaginal tape had the lowest initial stiffness (0.23 N/mm), i.e. low resistance to deformation at forces below the elastic limit, whereas the stiffest implant tested, a nylon tape, reached 6.83 N/mm. We concluded that the TVT and other wide-weave Prolene tapes have unique biomechanical characteristics. These properties may be at least partly responsible for the apparent clinical success of the implants.
