About

Aim: The study aim to assess the feasibly a large prospective multi-centre randomised study for comparing the relatively new "Single incision sub-urethral tapes" with the standard surgical treatment of female urodynamic stress incontinence (USI).

Full description

Single incision tension-free sub-urethral vaginal tapes procedures8 have been recently described in an attempt to avoid the blind passage of the trochars through the groin & the adductor muscles and consequently reducing the incidence & severity of postoperative leg pain. The obvious advantages would be shorter hospital stay, early recovery, early resumption of day to day activities & earlier return to work. A number of small prospective audits and case-series have been presented in international conferences reporting on the safety & outcomes for these procedures. However all these studies were for preliminary reports for proof of concept and therefore the studies populations were 15-70 women with short term follow-up of 2-3 month9-11.These studies have shown low perioperative complication rates: bladder injury 0-1%, vaginal erosion 1-3% & one study showing 1.3% pain at 6 weeks follow-up. The patient reported success rates were 77-93% at 2-3 month follow-up9-12.

Objectives:

1. Establish the feasibility of the "Single incision sub-urethral tapes" to be done under local anaesthesia.
2. The feasibility of randomisation to the standard surgical treatment TVT-O / TVT.
3. To compare the surgical approach in this relatively new procedure against the standard procedures as regard: Peri-operative complication rates, Postoperative pain, Time to discharge from the hospital,
4. To compare the outcomes as regard: Patient-reported cure rates, Patient satisfaction, Impact on Quality of life (QoL) and sexual function at 3 month & 1 -year follow-up. The objective cure rates will be assessed at 3 month follow-up.

137 participants in 2 patient groups

Single-incision Mini-slings (SIMS- Ajust)

Experimental group

Description:

AjustTM has polypropylene fixing anchors (one is fixed and the other adjustable) which are anchored onto the obturator membrane. The pulley like system enables adjustment of the tension once the arms have been anchored. Once in place, the anchors rest at right angles to insertion which is claimed to reduce the chances of anchor dislodgment

Treatment:

Procedure: sub-urethral tape (TVT-O)

standared med urethral sling (SMUS)

Other group

Description:

standard med urethral sling (SMUS)TVT-O, was done as originally described by Deleval et al.

Treatment:

Other: stand standard mid-urethral sling (TVT-O)
