Urogenital prolapse can have a significant impact on quality of life. The life time risk of requiring surgery for urogenital prolapse is 11%. Prolift mesh has recently been introduced to reduce repeat operation rate and for long-term benefit.
To evaluate the outcome of the treatment of urogenital prolapse with synthetic mesh.
A retrospective review of case notes of all women who underwent prolift mesh insertion for prolapse between July 2004 and June 2005, at Royal Alexandra Hospital Paisley UK. We looked at the presenting complaints, previous operation, intraoperative complications and complications at six weeks and six months follow-up.
Twenty-two procedures were carried out in the twelve months period. Age of the patients ranged from 55 to 82 years (median 64 yrs). Eleven had anterior Prolift (50%), Seven had posterior Prolift 31.8% and four total Prolift 18%. There were no intraoperative complications. All the patients had previous surgery for prolapse. Eight patients had anterior repair, six patients had posterior repair, and three patients had abdominal hysterectomy. Vaginal hysterectomy was carried out with mesh insertion as a concomitant procedure in seven cases (31.25%). All patients were seen at six weeks and six months after the surgery. Complications rate included mesh erosion one patient and suture material protruding in the vagina one patient, one patient had failed prolift operation. All the twenty-one patients were cured giving 95.4% success rate.
The use of prolene mesh in pelvic reconstructive surgery was associated with good outcome and minimal complications in this study.
Genital Prolapse surgery has varying degree of success. Synthetic meshes are increasingly used in the surgical management of pelvic organ prolapse in an attempt to improve the success rates and to increase longevity of repairs.
If there are no urinary symptoms urodynamics studies are not justified outside the research setting. Surgically the key issues are which technique produces the best; long-lasting anatomical result. There is no widely accepted and standardized technique for the management of recurrent prolapse. Multiple surgical techniques have evolved each supported enthusiastically by their proponents and some of the techniques involve the use of synthetic mesh material.
TYPES OF MESH REPAIR
Type of operation
Anterior and posterior
We carry out the posterior compartment mesh repair by using a midline incision from the perineum to the vaginal apex and the vagina detached from the rectum with a sharp dissection, which was extended laterally to the ischiorectal fossa, and superiorly onto the sacrospinous ligament. Fascial defect in the rectovaginal septum was repaired using 2/0 polydioxanon (PDS) interrupted sutures. Atrium mesh 10×15 cm was fashioned in a Y-shape, the arms of the Y, 2 cm wide and the body 5 cm wide. The arms of the Y were placed onto the sacrospinous ligament bilaterally with the main body of mesh overlaying the repaired rectovaginal fascia and the perineal body. The mesh was also stabilized with vicryl 2/0 sutures placed superiorly. And laterally onto the perineal body. We routinely performed rectal examination was in order to exclude damage or inadvertent placement of the sutures in the rectum.
Following placement of the mesh overlay the vagina was closed a cystoscopy and rectal examination was performed to exclude any urinary or rectal injury.
Twenty-two procedures were carried out in the twelve months period. Age of the patients ranged from 55 to 82 years (median 64 yrs). Eleven had anterior Prolift (50%), Seven were posterior Prolift 31.8% and Four total Prolift 18%. There were no intra operative complications. All the patients had previous surgery for prolapse. Eight patients had anterior repair, Six patients had posterior repair, and three patients had abdominal hysterectomy. Vaginal hysterectomy was carried out with mesh insertion as a concomitant procedure in seven cases (31.25%). All patients were seen at Six weeks and six months after the surgery. Complications rate included mesh erosion one patient and suture material protruding in the vagina one patient at the six months follow-up. One patient had failed total Prolift operation. All the twenty-one patients were cured giving 95.4% success rate.
This study reports on 22 women who had pelvic floor reconstruction with anterior, posterior or total mesh reinforcement. The overall cure rate at 6 weeks and 6months was 95.4%.
A study reports that  with total mesh one patient failed and the procedure had to be repeated similar to our own studies. The appearance of prolapse in a well supported compartment is an issue which occurs after all surgery for prolapse whether conventional or using mesh [2–4].
This finding seems to be comparable to what has been reported after sacrospinous colpopexy and given that the mesh is fixed through sacrospinous ligament bilaterally, may well be for the same reason.
One patient had concomitant vagina hysterectomy and posterior Prolift, while three patients had vaginal hysterectomy as a concomitant procedure and anterior Prolift. In all these cases the procedures were successful. The remaining three concomitant vaginal hysterectomies were in the total prolift group and among them an elderly lady 82 years had a failed total Prolift. This probably may well be because of her age that predisposes to significant supporting ligaments weaknesses. Our success rate of 95.4% is comparable to most studies [5–7].
There are various type of mesh in the markets, however type 1monofilament polypropylene mesh with large pore sizes is currently recommended to reduce complications such as mesh erosion, extrusion inflammation or infection [8–10]. We use a similar type of mesh in our studies. This study reports 22 women who underwent pelvic floor reconstructions, with anterior, posterior or total mesh reinforcement. The overall cure rate at six months for all the three compartments respectively was 95.4%.
Concern continues to be voiced regarding the risk of chronic infection and the potentially disastrous consequences of mesh finding its way within a hollow viscus such as bladder [11–13]. We found only 2 instances of mesh erosion/protrusion in our follow-up patients and both were easily managed with excision of the protruding mesh resulting in complete cure.
Some studies have reported an up to 26% mesh erosion rate and up to 38% dyspareunia rate. We did not have dyspareunia as complication.
Most cases of prolapse in the Caucasian population is due to age factors that weaken the ligaments supporting the pelvic structures . In this study the failure of the total mesh prolift was in the 82 year old lady. In an African population however most recorded cases of prolapse are due to the high parity and the patients are relatively younger. There is need to have a randomized trial to compare the effectiveness, of the various synthetic materials in our center in future. Cost is a prohibitive factor in purchasing the prolene mesh. It therefore implies in a low resource setting economy, especially the developing Nations, they will not be able to afford these prostheses for their practice.
Our study confirms that mesh prolift procedure is safe in the hands of trained surgeons, with a success rate of 95.4% and minimal complication rate. Large randomized trials of conventional surgery versus mesh insertion will be necessary to answer major question on both the anatomical and functional outcome of pelvic floor repair.
