OBJECTIVE Understanding the long-term comparative effectiveness of competing surgical repairs is essential as failures after primary interventions for stress urinary incontinence (SUI) may result in a third of women requiring repeat surgery. STUDY DESIGN We conducted a systematic review including English-language randomized controlled trials from 1990 through April 2013 with a minimum 12 months of follow-up comparing a sling procedure for SUI to another sling or Burch urethropexy. When at least 3 randomized controlled trials compared the same surgeries for the same outcome, we performed random effects model metaanalyses to estimate pooled odds ratios (ORs). RESULTS For midurethral slings (MUS) vs Burch, metaanalysis of objective cure showed no significant difference (OR, 1.18; 95% confidence interval [CI], 0.73-1.89). Therefore, we suggest either intervention; the decision should balance potential adverse events (AEs) and concomitant surgeries. For women considering pubovaginal sling vs Burch, the evidence favored slings for both subjective and objective cure. We recommend pubovaginal sling to maximize cure outcomes. For pubovaginal slings vs MUS, metaanalysis of subjective cure favored MUS (OR, 0.40; 95% CI, 0.18-0.85). Therefore, we recommend MUS. For obturator slings vs retropubic MUS, metaanalyses for both objective (OR, 1.16; 95% CI, 0.93-1.45) and subjective cure (OR, 1.17; 95% CI, 0.91-1.51) favored retropubic slings but were not significant. Metaanalysis of satisfaction outcomes favored obturator slings but was not significant (OR, 0.77; 95% CI, 0.52-1.13). AEs were variable between slings; metaanalysis showed overactive bladder symptoms were more common following retropubic slings (OR, 1.413; 95% CI, 1.01-1.98, P = .046). We recommend either retropubic or obturator slings for cure outcomes; the decision should balance AEs. For minislings vs full-length MUS, metaanalyses of objective (OR, 4.16; 95% CI, 2.15-8.05) and subjective (OR, 2.65; 95% CI, 1.36-5.17) cure both significantly favored full-length slings. Therefore, we recommend a full-length MUS. CONCLUSION Surgical procedures for SUI differ for success rates and complications, and both should be incorporated into surgical decision-making. Low- to high-quality evidence permitted mostly level-1 recommendations when guidelines were possible.

Case Report: Robot-Assisted Laparoscopic Boari Flap Ureteral Reimplantation

Megan O. Schimpf; Joseph R. Wagner

Creation of a Boari flap is an option for ureteral reimplantation with high transection or stricture of the ureter. The benefits of laparoscopic surgery include decreased blood loss, quicker recovery time, and improved cosmesis. Robot-assisted surgery offers intraoperative advantages, including three-dimensional visualization with magnification and wristed movements with additional degrees of freedom. A 75-year-old woman with a persistent ureteral stricture opted for robot-assisted surgery for definitive management. To optimize the repair with least tension, creation of a Boari flap was chosen intraoperatively. Surgery and recovery were uncomplicated. Robot-assisted laparoscopic surgery can be safely used for Boari flap ureteral reimplantation.

Universal ureteral stent placement at hysterectomy to identify ureteral injury: a decision analysis

Megan O. Schimpf; Ee Gottenger; Jr Wagner

Objective  Iatrogenic ureteral injury during gynaecological surgery is associated with increased morbidity when not diagnosed during the initial surgery. Preoperative insertion of ureteral catheters may enhance intraoperative recognition of injury and repair, but it is controversial. We sought to analyse the costs of this approach.

Pyogenic spondylodiscitis associated with sacral colpopexy and rectopexy: report of two cases and evaluation of the literature

Katie Propst; Elena Tunitsky-Bitton; Megan O. Schimpf; Beri Ridgeway

Pyogenic spondylodiscitis includes a spectrum of spinal infections such as discitis, osteomyelitis, epidural abscess, meningitis, subdural empyema, and spinal cord abscess. This is a rare complication of sacral colpopexy, but can lead to devastating consequences for the patient. We present two cases of pyogenic spondylodiscitis following sacral colpopexy. In addition, we discuss 26 cases of pyogenic spondylodiscitis reported in the literature from 1957 to 2012. Techniques to decrease rates of infection include proper identification of the S1 vertebra, awareness of the suture placement depth at the level of the sacrum and at the vagina, and early treatment of post-operative urinary tract and vaginal infections. Awareness of symptoms, timely diagnosis and multidisciplinary approach to management is essential in preventing long-term complications.

Difference in quality of life in women with urge urinary incontinence compared to women with stress urinary incontinence

Megan O. Schimpf; Minita Patel; David M. O’Sullivan; Paul K. Tulikangas

IntroductionWe evaluated whether women with urge urinary incontinence (UUI) have lower quality of life (QOL) than women with other forms of urinary incontinence.MethodsPatients completed three validated questionnaires when presenting for evaluation at a urogynecology practice and were divided into four groups based on their responses: those with symptoms of stress urinary incontinence (SUI), UUI, both SUI and UUI (mixed UI), and neither SUI nor UUI (controls).ResultsA total of 465 women were included: 53 women with UUI (11.4%), 101 with SUI (21.7%), 200 with mixed UI (43%), and 111 controls (23.9%). Overall, there was a significant difference (p < 0.001) in PFIQ bladder scale scores as a function of UI group, with individual mean PFIQ scores of 17.1 for controls, 22.3 for SUI, 32.7 for UUI, and 36.8 for mixed UI. Individually, all seven questions in the PFIQ bladder domain were significantly different by group (p ≤ 0.001).ConclusionsWomen with UUI and mixed UI have lower QOL scores than women without incontinence or with only SUI.

Occurrence of postoperative hematomas after prolapse repair using a mesh augmentation system

Christine A. LaSala; Megan O. Schimpf

BACKGROUND: Mesh-augmented repair kits are increasingly being used for anterior compartment defect repair and can be associated with complications. CASES: Two cases are presented of postoperative pelvic hematomas confirmed on computerized tomography scan after anterior repair with a mesh-augmented anterior vaginal prolapse repair system. Both resolved without requiring drainage, although one patient did require a blood transfusion, and the other required intravenous antibiotics to treat an infected hematoma. CONCLUSION: Significant complications may arise from this new technology. Further studies are needed to determine whether the benefits of this technology outweigh its risk of use.

Objective Given recent government investigations and media coverage of the controversy regarding mesh surgery, we sought to define patients’ knowledge and perceptions of vaginal mesh surgery. Study Design An anonymous survey was distributed to a convenience sample of new patients at urogynecology and female urology clinics at a single medical center during April to June 2012. The survey assessed patients’ demographics, information sources, and beliefs and concerns regarding mesh surgery. The Fisher’s exact test was used to identify predictors of patients’ beliefs regarding mesh. Logistic and linear regressions were used to identify predictors of aversion to surgery and higher concern regarding future surgery. Results One hundred sixty-four women completed the survey; 62.2% (102/164) indicated knowledge of mesh surgery for prolapse and/or incontinence and were included in subsequent analyses. The mean ± SD age was 58.0 ± 12.5 years, and 24.5% reported prior mesh surgery. The most common information source was television commercials (57.8%); only 23.5% of the women reported receiving information from a medical professional. Participants indicated the following regarding vaginal mesh: class-action lawsuit in progress (55/102 [54.0%]), causes pain (47/102 [47.1%]), possibility of rejection (35/102 [34.3%]), can cause bleeding and become exposed vaginally (30/102 [29.4%]), and should be removed owing to recall (28/102 [27.5%]). Of these women, 22.1% (19/86) indicated they would not consider mesh surgery. On multivariable logistic regression, level of concern, information from friends/family, and knowledge of class-action lawsuit predicted aversion to mesh surgery. Conclusion Nearly two thirds of new patients had knowledge of vaginal mesh surgery. We identified considerable misinformation and aversion to future mesh surgery among these women.

Anterior vaginal wall prolapse and voiding dysfunction in urogynecology patients

Megan O. Schimpf; David M. O’Sullivan; Christine A. LaSala; Paul K. Tulikangas

We investigated whether women with and without anterior vaginal wall prolapse have voiding differences. Women (n = 109) who presented to a urogynecology practice were categorized into two groups based on anterior vaginal wall prolapse: stages 0 and 1 and stages 2, 3, and 4. Women with prolapse were older than the women without prolapse but the groups were otherwise similar demographically. There was a higher rate of activity-related urine loss and use of wetness protection amongst women without prolapse. There was no significant difference for urgency symptoms or urge incontinence. Urodynamic testing found no significant differences for maximal flow rate or maximal urethral closing pressures. Postvoid residual volume and detrusor overactivity were not different but approached significance. Anterior vaginal wall prolapse of stage 2 or greater was not associated with urge incontinence or voiding function in this population. Women without prolapse were more likely to report stress incontinence.

OBJECTIVE: To update clinical practice guidelines on graft and mesh use in transvaginal pelvic organ prolapse repair based on systematic review. DATA SOURCES: Eligible studies, published through April 2015, were retrieved through ClinicalTrials.gov, MEDLINE, and Cochrane databases and bibliography searches. METHODS OF STUDY SELECTION: We included studies of transvaginal prolapse repair that compared graft or mesh use with either native tissue repair or use of a different graft or mesh with anatomic and symptomatic outcomes with a minimum of 12 months of follow-up. TABULATION, INTEGRATION, AND RESULTS: Study data were extracted by one reviewer and confirmed by a second reviewer. Studies were classified by vaginal compartment (anterior, posterior, apical, or multiple), graft type (biologic, synthetic absorbable, synthetic nonabsorbable), and outcome (anatomic, symptomatic, sexual function, mesh complications, and return to the operating room). We found 66 comparative studies reported in 70 articles, including 38 randomized trials; quality of the literature has improved over time, but some outcomes still show heterogeneity and limited power. In the anterior vaginal compartment, synthetic nonabsorbable mesh consistently showed improved anatomic and bulge symptom outcomes compared with native tissue repairs based on meta-analyses. Other subjective outcomes, including urinary incontinence or dyspareunia, generally did not differ. Biologic graft or synthetic absorbable mesh use did not provide an advantage in any compartment. Synthetic mesh use in the posterior or apical compartments did not improve success. Mesh erosion rates ranged from 1.4–19% at the anterior vaginal wall, but 3–36% when mesh was placed in multiple compartments. Operative mesh revision rates ranged from 3–8%. CONCLUSION: Synthetic mesh augmentation of anterior wall prolapse repair improves anatomic outcomes and bulge symptoms compared with native tissue repair. Biologic grafts do not improve prolapse repair outcomes in any compartment. Mesh erosion occurred in up to 36% of patients, but reoperation rates were low.
