Outcomes following treatment for pelvic floor mesh complications.

INTRODUCTION AND HYPOTHESIS: Our aim was to determine symptoms and degree of improvement in a cohort of women who presented following treatment for vaginal mesh complications. METHODS: This study was a follow-up to a multicenter, retrospective study of women who presented to four tertiary referral centers for management of vaginal-mesh-related complications. Study participants completed a one-time follow-up survey regarding any additional treatment, current symptoms, and degree of improvement from initial presentation. RESULTS: Two hundred and sixty women received surveys; we had a response rate of 41.1 % (107/260). Complete data were available for 101 respondents. Survey respondents were more likely to be postmenopausal (p = 0.006), but otherwise did not differ from nonrespondents. Fifty-one percent (52/101) of women underwent surgery as the primary intervention for their mesh complication; 8 % (4/52) underwent a second surgery; 34 % (17/52) required a second nonsurgical intervention. Three patients required three or more surgeries. Of the 30 % (30/101) of respondents who reported pelvic pain prior to intervention, 63 % (19/30) reported improvement, 30 % (9/30) were worse, and 7 % (2/30) reported no change. Of the 33 % (33/101) who reported voiding dysfunction prior to intervention, 61 % (20/33) reported being at least somewhat bothered by these symptoms. CONCLUSIONS: About 50 % of women with mesh complications in this study underwent surgical management as treatment, and <10 % required a second surgery. Most patients with pain preintervention reported significant improvement after treatment; however, almost a third reported worsening pain or no change after surgical management. Less than half of patients with voiding dysfunction improved after intervention.

Posterior pelvic floor prolapse and a review of the anatomy, preoperative testing and surgical management.

The vagina proper extends from the hymen to the cervix and uterus. The anterior wall of the rectum and the posterior vaginal wall are fused for approximately 3 to 4 cm into the vagina. Above this, a plane of dissection is easily created. Plastic repair of the posterior vagina that utilizes ''fascia'' are in fact using the split adventicia and fibromuscular walls of the vagina to support the anterior wall of the rectum. Evaluation of posterior vaginal wall defects requires not only an anatomical description of the prolapse, but also correlation of any functional derangements that may exist. Evaluation may include; defecography, bowel transit studies, manometry, endoluminal ultrasound and magnetic resonance imaging. Surgical correction of posterior vaginal wall prolapse includes vaginal, trans anal and abdominal approaches. Vaginal approaches include site specific repairs and traditional posterior colporrhaphy with levator ani placation. Graft augmentation has been described with both approaches in an effort to improve outcomes and decrease failure rates.

Sexual function following anti-incontinence surgery.

Stress urinary incontinence is a bothersome condition that may impact quality of life and lead to sexual disorders. However, while surgical repair significantly reduces incontinence, improvements in sexual symptoms are not guaranteed. Vaginal narrowing, diminished orgasm, pain, mesh erosion or decreased lubrication may occur following a small proportion of these interventions. It is important to counsel patients regarding their sexual function and expectations prior to and following any surgical procedure in order to mitigate any negative impact on their overall quality of life.

Randomised trial of laparoscopic Burch colposuspension versus tension-free vaginal tape: long-term follow up.

OBJECTIVE: To compare the long-term efficacy of laparoscopic Burch colposuspension with tension-free vaginal tape (TVT) for the treatment of urodynamic stress urinary incontinence (SUI). DESIGN: Long-term follow up from a prospective randomised trial. SETTING: Academic tertiary referral centre. SAMPLE: Seventy-two women with urodynamic SUI from two institutions. METHODS: Subjects were randomised to either laparoscopic Burch or TVT from August 1999 to August 2002. Follow-up evaluations occurred 6 months, 1 year, 2 years, and 4-8 years after surgery. MAIN OUTCOME MEASURES: Subjects completed the Incontinence Severity Index, Urogenital Distress Inventory 6 (UDI-6), Incontinence Impact Questionnaire (IIQ-7), and Patient Global Impression of Improvement (PGI-I) scales. RESULTS: Median follow-up duration was 65 months (range 12-88 months) with 92% completing at least one follow-up visit. Seventy-four percent of subjects had long-term (4-8 years) follow up. Fifty-eight percent of subjects receiving laparoscopic Burch compared with 48% of TVT subjects reported any urinary incontinence 4-8 years after surgery (Relative Risk (RR):1.19; 95% CI: 0.71-2.0) with no significant difference between groups. Bothersome SUI symptoms were seen in 11 and 8%, respectively, 4-8 years after surgery (P = 0.26). There was significant improvement in the postoperative UDI-6 and IIQ-7 scores in both groups at 1-2 years that were maintained throughout follow up with no significant differences between the groups. CONCLUSIONS: TVT has similar long-term efficacy to laparoscopic Burch for the treatment of SUI. A substantial proportion of subjects have some degree of urinary incontinence 4-8 years after surgery; however, the majority of incontinence is not bothersome.

A randomized trial of local anesthesia with intravenous sedation vs general anesthesia for the vaginal correction of pelvic organ prolapse.

The purpose of this study is to compare the feasibility of local anesthesia with IV sedation versus general anesthesia for vaginal correction of pelvic organ prolapse. Patients with pelvic organ prolapse who were scheduled for an anterior or posterior colporrhaphy, or an obliterative procedure, and who did not have a contraindication or preference to type of anesthesia were randomized to one of the two anesthesia groups. Nineteen patients were randomized to the general group and 21 patients were randomized to the local group. Mean operating room, anesthesia, and surgical time were similar in each group, and 10 patients in the local group bypassed the recovery room. Requests and doses of antiemetics, postoperative verbal numerical pain scores and length of hospital stay were similar between the two groups. Mean recovery room and total hospital costs were significantly lower in the local group. Local anesthesia with IV sedation is a feasible alternative for vaginal surgery to correct pelvic organ prolapse.

Anatomy and physiology of the pelvic floor.

Lower urinary tract function consists of a complex interplay of neural input consisting of both involuntary and voluntary controls interacting with specialized anatomical structures. Damage to anatomical support structures may lead to derangements in urethral and bladder function. In addition, disorders related to physiological and neurological function of the lower urinary tract can result in abnormalities in the storage and evacuation of urine. The ultimate goal in the evaluation and management of women with pelvic floor dysfunction is to correlate functional derangements with anatomical changes. The understanding of various pelvic support defects in the pelvic visceral supports also allows the physician to perform the correct surgery needed for successful outcomes.

High uterosacral vaginal vault suspension with fascial reconstruction for vaginal repair of enterocele and vaginal vault prolapse.

OBJECTIVE: The purpose of this study was to review retrospectively the functional and anatomic outcomes of women who underwent vaginal repair of enterocele and vault prolapse with the use of an intraperitoneal suspension of the vaginal vault to the uterosacral ligaments in conjunction with fascial reconstruction of the anterior and posterior vaginal wall. STUDY DESIGN: Two hundred two women with advanced symptomatic uterovaginal prolapse or posthysterectomy vault prolapse underwent a standard transvaginal procedure to correct their prolapse between January 1997 and June 2000. Anatomic results were assessed by standardized examination from 6 months to 3 years after the operation. Functional results were assessed subjectively and with standard quality of life questionnaires. The average age of the women was 60.3 years. Follow-up data were available for 168 of the 202 women. Fifty-three percent of the women had their uterus in place and underwent a vaginal hysterectomy. The prolapse repair was a primary procedure in 45.2% of the women and was performed for a recurrence or persistence in 54.8% of the women. Sixty percent and 78.6% of women underwent anterior and posterior repair, respectively. Thirty-five percent of the women underwent an anti-incontinence procedure. RESULTS: Eighty-nine percent of the women expressed satisfaction with the results of the procedure. Ten women (5.5%) underwent a repeat operation (by the authors) for recurrence of prolapse in one or more segments of the pelvic floor. Quality of life assessment revealed a significant reduction in all aspects of daily living, when the short forms of the incontinence impact questionnaire and urogenital distress inventory were evaluated before and after the operation. Major intraoperative complications included 5 cases (2.4%) of ureteral injury, 1 case of a small bowel injury, and 1 case of a pelvic abscess that required abdominal exploratory operation and diversion of the colon. CONCLUSION: High uterosacral ligament vaginal vault suspension with fascial reconstruction would seem to provide a durable anatomic repair with good functional improvement in patients with significant complex uterine or vaginal vault prolapse.

A randomized, double-blind placebo-controlled trial of the effects of the 5-hydroxytriptamine(4) agonist cisapride on the female urinary bladder.

OBJECTIVE: Anecdotal reports have proposed the use of the 5-hydroxytriptamine(4) agonist cisapride as a treatment for female voiding dysfunction on the basis of the known prokinetic actions of the medication. The purpose of our study is to assess the effects of this agent on the normal bladder in vivo. STUDY DESIGN: In this randomized, double-blind placebo-controlled trial, patients were randomized to receive either 20 mg cisapride or an identical placebo. They then underwent urodynamic evaluation that included uroflowmetry, multichannel filling cystometry, pressure-flow studies, and a urethral pressure profile. After a washout period of at least 7 days, subjects were then crossed over to the other arm and the tests were repeated. RESULTS: Twenty women without significant urinary incontinence agreed to participate. There was a decrease in the maximum cystometric capacity from 556 mL for placebo to 496 mL for cisapride (P <.001). There was no difference in the detrusor pressure at maximum flow, the maximum detrusor pressure, the flow rate, or the percentage of maximum cystometric capacity voided. CONCLUSIONS: In healthy women, cisapride caused a significant decrease in the maximum cystometric capacity, which could account for the higher reported rates of urinary frequency and urgency with this medicine. There was no evidence that this prokinetic agent improved voiding function.

Anatomic and functional outcome of vaginal paravaginal repair in the correction of anterior vaginal wall prolapse.

Over a 2-year period 45 patients with bilateral paravaginal support defects underwent vaginal paravaginal repair. Postoperative evaluations were conducted and anatomic outcome was determined by vaginal examination, with grading of vaginal wall support. Functional outcome was assessed by a standardized quality of life questionnaire, voiding dairy and standing stress test with a full bladder. Thirty-five patients had long-term follow-up with a mean of 1.6 years (range 1-85). The recurrence rates for displacement cystocele, enterocele and rectocele were 3% (1/35), 20% (7/35) and 14% (5/35), respectively. In no patients did vault prolapse develop or recur. Subjective or objective evidence of persistent stress urinary incontinence was found in 57% of patients (12/21). Vaginal paravaginal repair is a safe and effective technique for the surgical correction of anterior vaginal wall prolapse but has limited applicability in the surgical correction of genuine stress incontinence.

Vaginal configuration on MRI after abdominal sacrocolpopexy and sacrospinous ligament suspension.

An MRI study was conducted to compare the vaginal configuration of women who had undergone sacrospinous fixation with transvaginal needle suspension or abdominal sacrocolpopexy with retropubic colposuspension with that of normal controls. MRI examination demonstrated that in normal controls the lower vagina formed an acute angle (mean 53 degrees) with the pubococcygeal line and intersected the upper vagina at a mean angle of 145 degrees. In the abdominal repair group the lower vagina intersected the pubococcygeal line at a mean angle of 57 degrees and joined the upper segment at a mean angle of 137 degrees. In the vaginal repair group the lower vagina intersected the pubococcygeal line at a mean angle of 54 degrees and joined the upper segment at a mean angle of 220 degrees. Our study demonstrated that abdominal sacrocolpopexy with retropubic colposuspension more closely restored the vagina to its normal configuration, whereas sacrospinous fixation with transvaginal needle suspension creates an abnormal vaginal axis.

Suprapubic bladder drainage after extraperitoneal cystotomy.

OBJECTIVE: To observe the effects of cessation of continuous bladder drainage after short-term catheterization in women who had extraperitoneal cystotomies. METHODS: The study population included 84 women, 78 of whom had retropubic urethropexies and six of whom had retropubic paravaginal repairs. Intentional cystotomy was done intraoperatively to assure ureteral patency, bladder integrity, and no inadvertent suture penetration into the bladder. All cystotomies were closed in two layers with 3-0 chromic suture. Suprapubic catheters were placed intraoperatively in all cases. In all women except four with gross hematuria, continuous bladder drainage was stopped and voiding trials were started within 24 hours after surgery. Suprapubic catheters were removed when women spontaneously voided 80% of total bladder volume. RESULTS: Suprapubic catheters were discontinued on average 4.1 days after surgery (range 2.7-14.1 days). Average bladder volume at initial clamping of the suprapubic catheter was 382 mL (range 224-510 mL). At this volume the integrity of the cystotomy should have been challenged appropriately. The women were observed for a minimum of 3 months with no immediate or long-term complications. CONCLUSION: Extraperitoneal cystotomy in a nondependent portion of the bladder does not require continuous bladder drainage for more than 24 hours. This information should allow pelvic surgeons to be more liberal with intraoperative cystotomies if bladder integrity or ureteral patency needs to be confirmed.

Periurethral collagen injection for stress incontinence with and without urethral hypermobility.

OBJECTIVE: To compare the use of periurethral collagen injection in the treatment of female stress urinary incontinence due to intrinsic sphincter deficiency in women with and without urethral hypermobility. METHODS: A retrospective review was performed of 60 periurethral collagen injections performed on 40 consecutive women from January 1996 to December 1997. A review of the office chart and operative notes was performed to obtain demographic, urodynamic, and procedural data. Outcome data were obtained by personal or telephone interview, using patients' subjective assessments including an analog satisfaction scale. RESULTS: Nine of 40 patients (23%) had urethral hypermobility. Compared with patients without hypermobility, patients with hypermobility required a similar number of procedures (a mean of 1.9 compared with 1.4, P = .13) and required similar amounts of collagen on the first injection (5.6 mL compared with 5.3 mL, P = .69). Preoperative urodynamic parameters were similar in both groups. Rates of subjective dryness were equivalent in patients with and without hypermobility at 1 month (76% and 46%, P = .24) and at 6 months (71% and 32%, P = .09) following initial injection. A post hoc power analysis was performed to evaluate the primary study measures of continence at 1 and 6 months, and number of collagen injections. This revealed that a sample size of 40 patients would be sufficient to detect a 2.5-fold difference in number of injections and a 3-fold difference in subjective dryness. CONCLUSION: Coexisting urethral hypermobility should not preclude the use of collagen injections in women with stress urinary incontinence.

The anatomic and functional outcomes of defect-specific rectocele repairs.

OBJECTIVE: This study was undertaken to evaluate the anatomic, functional, and quality-of-life effects of site-specific posterior colporrhaphy in the surgical management of rectocele. STUDY DESIGN: In a retrospective observational study 125 patients were studied who had undergone site-specific posterior colporrhaphy between 1995 and 1996, either alone or in conjunction with other pelvic procedures. Physical examination was performed >/=6 months after the operation to assess the anatomic success of the repair. Standardized questionnaires were used to assess quality of life, sexual function, and bowel function. RESULTS: Surgical correction was found at follow-up examination to have been achieved in 82% of eligible patients (73/89). All daily aspects of living improved significantly (P <.05), including ability to do housework (56% improvement or cure), travel (58% improvement or cure), and social activities (60% improvement or cure). Emotional well-being also significantly improved after the operation, as measured by thoughts of embarrassment (57% improvement or cure) or frustration (71% improvement or cure). Sexual function was not affected; however, reports of dyspareunia significantly (P <.04) improved or were cured after the operation in 73% of patients (19/26), worsened in 19% of patients (5/26), and arose de novo in 3 patients. Results showed no other significant differences in vaginal dryness, orgasm ability, sexual desire, sexual frequency, or sexual satisfaction. Bowel symptoms were assessed subjectively and were noted to have significantly improved (P <.008) after the operation. The following improvement or cure rates were obtained: stooling difficulties, 55%; pelvic pain or pressure, 73%; vaginal mass, 74%; and splinting, 65%. CONCLUSION: This study indicates that defect-specific posterior colporrhaphy is equal to or superior to traditional posterior colporrhaphy. This type of repair provides durable anatomic support and is successful in restoring bowel function. It does not detrimentally affect sexual function, may aid in the resumption of sexual activity, and significantly improves quality of life and social aspects of daily living.

A retrospective comparison of abdominal sacrocolpopexy with Burch colposuspension versus sacrospinous fixation with transvaginal needle suspension for the management of vaginal vault prolapse and coexisting stress incontinence.

The objective of this study was to compare the surgical outcome of abdominal sacrocolpopexy and Burch colposuspension with sacrospinous fixation and transvaginal needle suspension in the management of vaginal vault prolapse and coexisting stress incontinence. One hundred and seventeen women with vaginal vault prolapse and coexisting stress incontinence were surgically managed over a 7-year period. The first 61 consecutive women who underwent sacrospinous fixation and transvaginal needle suspension comprised the vaginal group, and the following 56 consecutive women who underwent abdominal sacrocolpopexy and Burch colposuspension comprised the abdominal group. Office records were reviewed to assess the presence of recurrent prolapse and urinary incontinence during postoperative follow-up. Objective follow-up was available for 101 women. Mean duration of follow-up was 24.0 +/- 15 months for the vaginal group, and 23.1 +/- 12.6 months for the abdominal group. The incidence of recurrent prolapse to or beyond the hymen (33% vs. 19%, P=0.0505) and lower urinary tract symptoms (26% vs. 13%, P = 0.0506) were significantly higher in the vaginal group than in the abdominal group. Our data suggest that the combined abdominal approach has a lower incidence of recurrent prolapse and lower urinary tract symptoms than the combined vaginal approach in managing vaginal vault prolapse and coexisting stress incontinence.

Pharmacologic causes of female incontinence.

The etiology of female urinary incontinence is complex and multifactorial. Many medications have adverse effects on the lower urinary tract, including the promotion of incontinence in certain women. Medications may cause incontinence through three main mechanisms: decreased intraurethral pressure, increased intravesical pressure, and indirect effects on the lower urinary tract. Careful adjustments of a patient's medications based on a knowledge of pharmacologic mechanisms of action may restore continence in some women.
