Trocar-assisted sling suspension for stress urinary incontinence: three-year follow-up.

STUDY OBJECTIVE: To evaluate 3-year outcomes of trocar-assisted sling suspension (TASS) for genuine stress incontinence.

DESIGN: Retrospective review (Canadian Task Force classification II-2).

SETTING: University-based, tertiary-level center for endoscopic surgery.

PATIENTS: One hundred forty women with genuine stress incontinence with bladder neck hypermobility.

INTERVENTION: After standard surgery preparation and general endotracheal anesthesia, TASS was performed. The periurethral space and thicker parts of the pubocervical fascia were opened from the vagina. A 0.5-cm incision was made on both sides of the lower abdomen and was measured 4-cm lateral to the linea album and 2-3-cm above the pubic bone. A trocar was used to penetrate the incision site to the space of Retzius. A 2-cm x 30-cm folded polypropylene mesh was placed inside the vagina and was then pulled out of the trocar sheath by a laparoscopic forceps.

MEASUREMENTS AND MAIN RESULTS: All patients completed the procedures without exception. The average blood loss was less than 50 mL (range 10-200 mL). The operative time ranged from 20 to 90 minutes with a mean time of 32 +/- 12 minutes. Eleven patients had voiding difficulty. Six of them voided well after intermittent self-catheterization performed 28 days postoperatively. Seven patients had poor healing of the anterior vaginal wall; therefore, removal of mesh and wound repair were performed. One patient suffered from a retroperitoneal hematoma, and one patient had an intraoperative bladder injury. The overall complication rate was 14.3%. During 12-36 months of follow-up, 134 of 140 patients (95.7%) were satisfied with the surgery.

CONCLUSIONS: Based on the results of our pilot study, TASS is quite feasible as a method of treatment for stress urinary incontinence. The surgery is not difficult to perform when compared with Burch colposuspension. Moreover, it encompasses the simplicity and effectiveness of tension-free vaginal tape surgery. In addition, TASS also can correct lateral wall defects such as cystocele.
