Anatomy of the sigmoid colon, rectum, and the rectovaginal pouch in women with enterocele and anterior rectal wall procidentia.

This study describes the anatomy of the rectovaginal pouch, the sigmoid colon, and rectum in women with posterior enterocele and anterior rectal wall procidentia. The anatomy of rectovaginal pouch, sigmoid colon, and rectum was described in 36 women with an enterocele (group A) and compared with those of 43 women (group B) without pelvic organ prolapse. Women with previous incontinence or prolapse surgery were excluded. The mean age in group A was 58 years (40-75) and in group B 35 years (19-64; P < 0.001). There were 15 nulliparas in group B. Nine women in group A had an internal anterior rectal wall procidentia, and one woman had an external anterior rectal wall procidentia. In group A, the rectovaginal pouch was significantly deeper, the sigmoid mesocolon at S1 shorter and showed more often a straight course (P < 0.05). These characteristics (termed "grande fosse pelvienne") were present in 23 women (64%) in group A and in 6 (14%) in group B, three of the latter were young nulliparas (P < 0.001). Age, parity, menopausal status, body mass index, constipation, and varicose veins were not associated with a grande fosse pelvienne. The typical anatomy in women with an enterocele and anterior rectal wall procidentia was a sigmoid colon with a straight course and a short mesentery at S1 and a rectovaginal pouch that covered more than half of the vaginal length. It may be a congenital condition and important in the development of an enterocele and rectal wall procidentia.

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.

Surgical management of anterior vaginal wall prolapse: an evidencebased literature review.

The aim of this review is to summarize the available literature on surgical management of anterior vaginal wall prolapse. A Medline search from 1966 to 2004 and a hand-search of conference proceedings of the International Continence Society and International Urogynecological Association from 2001 to 2004 were performed. The success rates for the anterior colporrhaphy vary widely between 37 and 100%. Augmentation with absorbable mesh (polyglactin) significantly increases the success rate for anterior vaginal wall prolapse. Abdominal sacrocolpopexy combined with paravaginal repair significantly reduced the risk for further cystocele surgery compared to anterior colporrhaphy and sacrospinous colpopexy. The abdominal and vaginal paravaginal repair have success rates between 76 and 100%, however, no randomized trials have been performed. There is currently no evidence to recommend the routine use of any graft in primary repairs, and possible improved anatomical out-comes have to be tempered againstcomplications including mesh erosions, infections and dyspareunia.

Surgical management of posterior vaginal wall prolapse: an evidence-based literature review.

The aim of this review is to summarize the available literature on gynecological management of posterior vaginal wall prolapse. A MEDLINE search and a hand search of conference proceedings of the International Continence Society and International Urogynecological Association was performed. Two randomized trials demonstrated that the transvaginal approach to rectocele is superior to the transanal repair in terms of recurrent prolapse. The traditional posterior colporrhaphy with levator ani plication was largely superceded by fascial repairs with similar anatomic success rates but favorable functional outcome. The midline fascial plication may offer a superior anatomic and functional outcome compared to the discrete site-specific fascial repair. Controlled studies are necessary to evaluate whether a sacrocolpopexy combined with posterior mesh interposition is an effective alternative to the transvaginal repair. There is currently no evidence to recommend the routine use of any graft and complications such as mesh erosion, infection, and rejection have to be considered.

Sacrocolpopexy for vault prolapse and rectocele: do concomitant Burch colposuspension and perineal mesh detachment affect the outcome?

OBJECTIVE: This study compares the effect of abdominal sacrocolpopexy with posterior Teflon mesh interposition with and without concomitant Burch colposuspension on the posterior compartment. STUDY DESIGN: This retrospective review includes 49 consecutive women who underwent sacrocolpopexy for vault or uterine prolapse stage 2 or higher and rectocele; 25 of them had a concomitant Burch colposuspension for urodynamic stress incontinence. Postoperative bladder, bowel and sexual function and recurrent pelvic organ prolapse was assessed at > or =12 months. RESULTS: There was no recurrent vault prolapse. Rectoceles (stage 2) recurred in 5 women (21%) without and in 8 women (36%) with Burch colposuspension ( P > .05). The mesh became detached by >2 cm from its perineal position in 30% of the cases, which was associated with excessive defecation straining ( P = .04). Rectocele stages significantly correlated with mesh detachment ( P > .001) but not with obstructed defecation ( P > .05). CONCLUSION: Sacrocolpopexy was effective if the mesh did not become detached from its perineal position. Concomitant Burch colposuspension did not seem to affect the posterior compartment adversely in this small case series.

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.

Effects of voluntary pelvic floor contraction and relaxation on the urethral closure pressure.

The aim of this study was to assess the effects of voluntary pelvic floor contraction and voluntary pelvic floor relaxation on the urethral closure pressure at rest. In 104 consecutive women, three urethral pressure profiles were performed: standard profile at rest, with voluntary pelvic floor contraction and with voluntary pelvic floor relaxation. A low-pressure urethra was defined as a maximum urethral closure pressure of < or =20 cmH(2)O. The age ranged between 24 and 82 years. The maximum urethral closure pressure at rest was significantly augmented during pelvic floor contraction (mean: 18 cmH(2)O). Compared with the first profile, it decreased significantly with pelvic floor relaxation (mean decrement: 8 cmH(2)O). A low-pressure urethra was detected in 5 women during the first profile and in a further 11 during pelvic floor relaxation. Because of the significant influence of pelvic floor activity on the urethral closure pressure at rest, the scientific and clinical credibility of urethral pressure measurements remain questionable.

Does Burch colposuspension cure coital incontinence?

OBJECTIVE: The purpose of this study was to evaluate the effect of Burch colposuspension for stress urinary incontinence on concomitant coital incontinence. STUDY DESIGN: The urogynecology database was searched for sexually active women, who experienced coital incontinence on vaginal penetration, orgasm, or both and who had subsequently undergone Burch colposuspension for urodynamic stress incontinence. The women were interviewed or sent a questionnaire on postoperative bladder and sexual function after a minimum follow-up time of 6 months. RESULTS: Thirty of 43 women answered the questionnaire. Preoperatively, 22 women (73%) experienced urinary leakage during penetration, 3 (10%) during orgasm and 5 (17%) at both. Stress incontinence symptoms were successfully treated in 23 (77%). Coital incontinence was cured in 21 of 30 (70%) and improved in 2. CONCLUSION: The results of this small series suggest that coital incontinence is likely to be cured or improved when stress incontinence has been successfully treated by Burch colposuspension.

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

Childbirth-induced trauma to the urethral continence mechanism: review and recommendations.

To summarize the literature on immediate pelvic floor damage from childbirth and episiotomy, a MEDLINE search of English language articles published from 1983 to 2001 was performed. Vaginal delivery causes varying degrees of muscular, neuromuscular, and connective tissue damage. This damage may result in urinary and/or fecal incontinence. Routine midline episiotomy increases the risk of third- and fourth-degree perineal lacerations, which may lead to fecal incontinence. Routine use of mediolateral episiotomy does not prevent urinary incontinence (UI) or severe perineal tears. It is possible to reduce the rate of mediolateral episiotomy to as low as 20% in primiparas without increasing the risk of anal sphincter damage. Control of obesity before delivery, as well as pelvic floor exercises and regular physical exercise both before and after delivery, seem to reduce the risk of postpartum UI.

Pharmacologic treatment of stress urinary incontinence: expectations for outcome.

Several classes of drugs have been investigated for their efficacy in treating stress urinary incontinence (SUI). Despite targeting the mechanisms known to be involved in maintaining continence, few have provided the desired benefits without causing significant adverse effects. Duloxetine, the newest drug to be extensively evaluated for SUI treatment, appears to be both safe and effective. None of the drugs tested thus far has proved to be curative, however. Treatment strategies therefore are aimed at improving the quality of life of patients and should take into account their individual needs and preferences.

Bulking agents for stress urinary incontinence: short-term results and complications in a randomized comparison of periurethral and transurethral injections.

The purpose of our study was to compare the two standard routes of urethral bulking injection in a prospective randomized trial. Forty women with genuine stress incontinence (n = 36), or mixed incontinence with a minor and controlled urge component (n = 4), participated in a urethral bulking agent trial. All patients had a standardized preoperative evaluation which included history, physical examination, assignment of incontinence status on a Stamey grading scale, postvoid residual (PVR) determination, Valsalva leak-point pressure, maximal urethral closure pressure, functional urethral length, Q-tip excursion angle, quantitative pad test, and completion of a quality of life questionnaire. On the day of injection they were randomly assigned to a periurethral or transurethral route of injection based on a computer-generated block randomization scheme. An ultrasound-determined PVR was obtained on all patients after injection. If self-catheterization was necessary, and the PVR was > 200 ml, urinary retention was diagnosed. Postoperative assessment included a patient interview, subjective assessment of improvement, PVR, voiding diary, and assignment of incontinence grade. At the screening visit there were no significant differences between the groups for any variables except type of stress incontinence. With short-term follow-up both transurethral and periurethral routes of injection seem to be equally efficacious. In the periurethral injection group there was a higher rate of postoperative retention; this group had a significantly higher volume of injectable agent used. There was no significant difference in risk of urinary tract infections between the two groups. We conclude that both periurethral and transurethral methods of bulking agent injection for stress urinary incontinence are equally efficacious, with minimal morbidity.
