Mesh augmentation during pelvic-floor reconstructive surgery: risks and benefits.

PURPOSE OF REVIEW: Synthetic meshes are increasingly used in the surgical management of stress urinary incontinence and pelvic-organ prolapse in an attempt to improve success rates and increase the longevity of repairs. This review describes and analyses complications following pelvic-floor procedures employing synthetic meshes. RECENT FINDINGS: Type I monofilament polypropylene mesh with a large pore size is currently the mesh of choice. Chronic inflammation is a typical host response, whereas acute inflammation and predominant CD20+ lymphocyte infiltration represent an adverse host reaction and may result in defective healing. Mesh properties influence the performance and complication rate. Mesh-related complications after midurethral slings and mesh sacrocolpopexies with monofilament polypropylene are rare. An up to 26% mesh erosion rate and up to 38% dyspareunia rate with vaginally introduced mesh for pelvic-organ prolapse repair has been reported. Concurrent hysterectomy seems to increase mesh erosion rates. SUMMARY: Surgeons should be aware of the potential complications of synthetic meshes. Until data on the safety and efficacy of synthetic mesh in vaginal reconstructive surgery emerge, its routine use outside of clinical trials cannot be recommended.

Severe mesh complications following intravaginal slingplasty.

OBJECTIVE: Synthetic meshes are increasingly used in the management of stress urinary incontinence and pelvic organ prolapse. This report describes severe complications following anterior and/or posterior intravaginal slingplasties employing a multifilament polypropylene mesh. METHODS: We describe the symptoms, findings, subsequent management, and outcome of 19 consecutive women who have been referred with complications following anterior (n = 11) and/or posterior intravaginal slingplasty (n = 13) employing the multifilament polypropylene tape. RESULTS: The main indications for removal of the 11 anterior intravaginal slings were intractable mesh infection in 6 women, retropubic abscess with cutaneous sinus in one, and vesico-vaginal fistula in one, intravesical mesh and pain syndrome in one, and voiding difficulties and pain syndrome in two. The main indications for removal of the 13 posterior intravaginal slings were intractable mesh infection in three and pain syndrome and dyspareunia in 10 women. Removal of the slings was performed after a median time of 24 months post-slingplasty. At follow-up between 6 weeks and 6 months, in all women genital pain, chronic vaginal discharge and bleeding, voiding, and defecation difficulties had been markedly alleviated (5) or they had ceased (14). Twelve of 17 sexually active women (71%) resumed sexual intercourse without difficulties. Ten women required subsequent surgery for stress incontinence and pelvic organ prolapse. CONCLUSION: Surgeons should be aware of the potential complications of synthetic meshes. Until data on the safety and efficacy of the intravaginal slingplasties are available, these procedures cannot be recommended.

Pubovaginal sling versus transurethral Macroplastique for stress urinary incontinence and intrinsic sphincter deficiency: a prospective randomised controlled trial.

OBJECTIVE: To compare the pubovaginal sling and transurethral Macroplastique in the treatment of female stress urinary incontinence (SUI) and intrinsic sphincter deficiency (ISD). DESIGN: A prospective randomised controlled trial comparing two surgical treatments for SUI and ISD. SETTING: Tertiary referral urogynaecology unit in Australia. POPULATION: Women with SUI and ISD who were suitable for either surgical technique. METHODS: Forty-five women with SUI and ISD were randomly allocated the pubovaginal sling (n = 22) or transurethral Macroplastique (n = 23). Subjective and objective success rates, patient satisfaction and cost measurements at six months and one year following surgery were the primary outcome measures. A telephone questionnaire survey was performed at a mean follow up period of 62 months (43-71). MAIN OUTCOME MEASURE: Comparison of success rates, complications and costs. RESULTS: The symptomatic and patient satisfaction success rates were similar following the sling and Macroplastique with the objective success rate being significantly greater (P < 0.001) following the sling (81%vs 9%). Macroplastique had significantly lower morbidity but was more expensive than the sling (P < 0.001). Response rate at 62 months follow up was 60% in both groups with the sling group reporting better continence success (69%vs 21%) and satisfaction rates (69%vs 29%, P = 0.057). CONCLUSIONS: The pubovaginal sling was more effective and economical than transurethral Macroplastique for the treatment of SUI and ISD. However, transurethral Macroplastique remains an appropriate treatment in selected cases of SUI and ISD.

Abdominal sacral colpopexy or vaginal sacrospinous colpopexy for vaginal vault prolapse: a prospective randomized study.

OBJECTIVE: The purpose of this study was to compare the abdominal sacral colpopexy and vaginal sacrospinous colpopexy in the treatment of vaginal vault prolapse. STUDY DESIGN: Ninety-five women with vaginal vault prolapse were allocated randomly to sacral colpopexy (47 women) or sacrospinous colpopexy (48 women). Primary outcome measurements include subjective, objective, and patient-determined success rates. Secondary outcomes include the impact on bowel, bladder, and sexual function, cost, and quality of life. RESULTS: Two years after the operation (range, 6-60 months), the subjective success rate was 94% in the abdominal and 91% in the vaginal group (P=.19). The objective success rate was 76% in the abdominal group and 69% in the vaginal group (P=.48). The abdominal approach was associated with a longer operating time, a slower return to activities of daily living, and a greater cost than the sacrospinous colpopexy (P<.01). Both surgeries significantly improved the patient's quality of life (P<.05). CONCLUSION: Abdominal sacral colpopexy and vaginal sacrospinous colpopexy are both highly effective in the treatment of vaginal vault prolapse.

Midline rectovaginal fascial plication for repair of rectocele and obstructed defecation.

OBJECTIVE: To estimate the efficacy of midline fascial plication of the posterior vaginal wall in women with rectoceles and obstructed defecation. METHODS: Prospective evaluation of 38 consecutive women with symptomatic rectoceles (stage II or greater) and obstructed defecation included pre- and postoperative standardized pelvic floor questions, pelvic organ prolapse quantification measurements, validated bowel function questionnaires, defecating proctogram, and patient satisfaction. Reviews were conducted by nonsurgical coauthors. RESULTS: The median follow-up was 12.5 months (range 2.5-26 months). The subjective success rates were 97% (95% confidence interval [CI] 0.83-1.00%) at 12 months and 89% (95% CI 0.55-0.98%) at 24 months. The objective success rates were 87% (95% CI 0.64-0.96%) at 12 months and 79% (95% CI 0.51-0.92%) at 24 months. The average points, Ap and Bp, were significantly reduced from -0.1 (range -2 to 3) and 1.1 (range -1 to 8), preoperatively, to -2.6 (range -3 to -1) and -2.5 (range -3 to 0), postoperatively, respectively (P <.001). Depth of rectocele also reduced postoperatively on defecating fluoroscopy (P <.001). The correction of the anatomical defect was associated with improved functional outcome, with 33 women (87%) no longer experiencing obstructed defecation, and there was a significant reduction in postoperative straining to defecate, hard stools, and dyspareunia (P =.001). The improved anatomical and functional outcomes were reflected in the fact that 97% of the women reported very high patient satisfaction. CONCLUSION: Midline fascial plication is effective in correcting anatomical and functional outcomes associated with symptomatic rectoceles and obstructed defecation. LEVEL OF EVIDENCE: III
