Dexamethasone administration to improve patient recovery in ambulatory vaginal reconstructive surgery: a randomized prospective trial.

INTRODUCTION AND HYPOTHESIS: Dexamethasone is a potent glucocorticoid that may improve quality of recovery (QoR). We hypothesized that standard administration of dexamethasone at induction may improve QoR compared to placebo in subjects undergoing ambulatory vaginal reconstructive surgeries. METHODS: This was a randomized prospective clinical trial on subjects scheduled for ambulatory vaginal reconstructive surgery for prolapse and/or urinary incontinence. Intervention arm subjects were administered dexamethasone and the control group, a placebo (normal saline). Timing of administration, anesthesia medications, postoperative pain medications, and antiemetics were standardized. Primary outcome was difference in QoR (QoR-40) scores 24-48 h after surgery. Power analysis estimated that 27 subjects were required in each group to detect a difference in QoR-40 scores with 80% power and an alpha of 0.05. RESULTS: Fifty-one subjects were enrolled and randomized. 4 withdrew, 1 was excluded, and 46 were analyzed. For the primary outcome, there was no difference in the QoR-40 between the dexamethasone and placebo group (--13.5 vs -19.6, p=0.24). Postoperative nausea vomiting intensity scores were not different (8.33 vs 9.09, p=1). Pain scores were similar in the two groups (6.0 vs 4.7, p=0.12). Although not statistically significant, surgical satisfaction at 6 weeks was better with dexamethasone (23.5 vs 26.9, p=0.09). CONCLUSION: Based on this study, a single dose of dexamethasone at the time of induction prior to ambulatory vaginal reconstructive surgery was not associated with improved QoR. Standardized anesthesia protocols may play a role in postoperative nausea, pain control, and thereby QoR in patients undergoing ambulatory vaginal reconstructive surgeries.

FIGO recommendations: Use of midurethral slings for the treatment of stress urinary incontinence.

BACKGROUND: Stress urinary incontinence (SUI) is a global problem. It can significantly adversely impact a woman's quality of life. The use of synthetic mesh in vaginal surgery is controversial, especially when used for pelvic organ prolapse surgery. Although negative effects have been reported, the synthetic mesh midurethral sling (MUS) is considered to be safe and effective in the surgical treatment of SUI. OBJECTIVES: To provide evidence-based data and recommendations for the obstetrician/gynecologist who treats women with SUI and performs or plans to perform MUS procedures. METHODS: Academic searches of MEDLINE, the Cochrane Library, Embase, and Google Scholar articles published between 1987 and March 2020 were performed by a subgroup of the Urogynecology and Pelvic Floor Committee, International Federation of Gynecology and Obstetrics (FIGO). SELECTION CRITERIA: The obtained scientific data were associated with a level of evidence according to the Oxford University Centre for Evidence-Based Medicine and GRADE Working Group system. In the absence of concrete scientific evidence, the recommendations were made via professional consensus. RESULTS: The FIGO Urogynecology and Pelvic Floor Committee reviewed the literature and prepared this evidence-based recommendations document for the use of MUS for women with SUI. CONCLUSIONS: Despite the extensive literature, there is a lack of consensus in the optimal surgical treatment of SUI. These recommendations provide a direction for surgeons to make appropriate decisions regarding management of SUI. The MUS is considered safe and effective in the treatment of SUI, based on many high-quality scientific publications and professional society recommendations. Comprehensive long-term data and systemic reviews are still needed, and these data will become increasingly important as women live longer. These recommendations will be continuously updated through future literature reviews.

Comparison of Methods to Identify Stress Urinary Incontinence in Women With Pelvic Organ Prolapse.

OBJECTIVE: The aim of the study was to compare which test is most sensitive in identifying stress urinary incontinence (SUI) in women with pelvic organ prolapse using urodynamics (UDS) as the criterion standard: cough stress test (CST) or pyridium pad test. METHODS: This was a prospective study of women with pelvic organ prolapse stage II or greater who desired surgical management for prolapse. Each patient underwent preoperative urinary testing: UDS, CST, and a 24-hour pyridium pad test. RESULTS: A total of 84 patients were analyzed. Using UDS as the criterion standard, both the CST and the pyridium pad test showed a fair agreement with UDS outcomes (κ = 0.27 for both tests). There was no statistically significant difference between the CST and the pyridium pad test, with estimated sensitivities of 34.4% versus 40.6% (P = 0.791), specificities of 90.4% versus 84.6% (P = 0.508). The pyridium pad test was found to have a statistically significant difference in identifying the subjective complaint of SUI (38.6%, P = 0.003) compared with other tests. Patients with occult incontinence were identified 42.5%, 17.5%, and 10% of the time during UDS, CST, and pyridium pad testing, respectively. CONCLUSION: Our data suggest that the sensitivities of the CST and pyridium pad test for stress incontinence and occult stress incontinence in patients with pelvic organ prolapse are low when compared with UDS as the criterion standard. Urodynamics has an important role in preoperative identification of occult SUI.

Optimal timing of a second postoperative voiding trial in women with incomplete bladder emptying after vaginal reconstructive surgery: a randomized trial.

BACKGROUND: Rates of postoperative incomplete bladder emptying vary significantly after pelvic reconstructive surgery. With enhanced recovery protocols the paradigm is shifting towards same-day discharge and the rates of incomplete bladder emptying are expected to increase. The optimal length of time for postoperative catheter drainage has not been clearly established. There are no current studies that assess the optimal timing of a repeat voiding trial in women who have unsuccessful same day voiding trials. OBJECTIVE: This study aimed to compare the outcomes of a second voiding trial performed 2-4 days (earlier group) vs 7 days (later group) postoperatively in women with incomplete bladder emptying after vaginal prolapse surgery. Secondary aims included postoperative urinary tract infection rates, total days with a catheter, and patient-reported catheter bother between groups. STUDY DESIGN: Across 2 sites, women undergoing multicompartment vaginal repair were enrolled. Within 6 hours postoperatively, subjects had an active retrograde voiding trial. Those who passed this voiding trial exited the study; those who had persistent incomplete bladder emptying (postvoid residual >100 mL) had a transurethral indwelling catheter placed and were randomized to return for an earlier (postoperative day 2-4) vs later (postoperative day 7) follow-up office voiding trial. Subjects were followed for 6 weeks after surgery. The primary outcome was the rate of unsuccessful repeat office voiding trial. Secondary outcomes included rates of urinary tract infection, total days with a catheter, and subjective catheter bother. A power calculation based on a projected 31% difference, a power of 0.8, and an alpha of 0.05 revealed that 30 subjects were needed in each group. RESULTS: A total of 102 subjects were enrolled; 38 exited on postoperative day 0, leaving 64 subjects for randomization (4 of whom withdrew after randomization). A comparison of data revealed that randomization was effective, with no differences between the earlier and later groups in terms of demographic data or surgical procedures. Using an intention-to-treat analysis, women in the earlier group were more likely to be unsuccessful in their follow-up office voiding trial (23.3%) than the later group (3.3%), with a risk difference of 20% (95% confidence interval, 3.56-36.44) and a relative risk of 7.00 (95% confidence interval, 0.92-53.47; P=.02). A number-needed-to-treat calculation found that for every 5 patients using a catheter for 7 days postoperatively, 1 case of persistent postoperative incomplete bladder emptying was prevented. Rates of catheter bother did not differ between groups at the time of the follow-up office voiding trial or at 6 weeks (P=.09 and P=.20, respectively). Urinary tract infection rates were higher in the earlier group but did not reach statistical significance (23% vs 7%, P=.07). Regression analysis revealed that subjects who required additional pain medication refills were 9.6 times (95% confidence interval, 1.24-73.77) more likely to have persistent incomplete bladder emptying after the follow-up office voiding trial. CONCLUSION: Women with incomplete bladder emptying after multicompartment prolapse repair had a 7-fold higher risk of an unsuccessful repeat office voiding trial if performed within 4 days of surgery than when performed within 7 days of surgery. In addition, requiring additional prescriptions for analgesia increased the risk of an unsuccessful follow-up office voiding trial.

Anesthetics' role in postoperative urinary retention after pelvic organ prolapse surgery with concomitant midurethral slings: a randomized clinical trial.

INTRODUCTION AND HYPOTHESIS: Spinal anesthesia can be a potential risk factor for postoperative urinary retention (POUR). Our objective was to compare POUR rates for outpatient vaginal pelvic floor surgeries when using spinal versus general anesthesia. Our hypothesis was that spinal anesthesia would have higher POUR rates compared with general anesthesia. METHODS: This was a randomized clinical trial on subjects undergoing outpatient pelvic organ prolapse (POP) surgery with a concomitant midurethral sling (MUS). Subjects were discharged home the same day as surgery. Subjects were excluded if they had a preoperative post-void residual > 150 ml, they were < 40 years of age, surgery was < 1 h, or they had contraindications to spinal or general anesthesia. A standardized voiding trial was performed. The primary aim was to compare POUR rates between anesthesia groups. A power analysis estimated 28 subjects were required per group to detect a 37% difference with 80% power and an alpha of 0.05. RESULTS: The trial was registered at ClinicalTrials.gov on July 15, 2015. Sixty-one subjects were enrolled between June 22, 2015, and December 31, 2017. Three were excluded, leaving 29 in each group. Groups were similar in demographics. For the primary outcome, there was a 14.3% difference in POUR rates between spinal and general anesthesia, which did not reach statistical significance based on our power calculation (p = 0.2516). CONCLUSIONS: Based on this study, there is not an increased rate of POUR with the use of spinal anesthesia for POP surgery with MUS. However, since there was a trend toward higher rates of POUR in the spinal group, it is possible that a larger powered study design would be able to detect a statistically significant difference between the groups. Based on these findings, if surgical patients would benefit from spinal anesthesia, the risk of urinary retention should not be considered a reason to not utilize this form of anesthesia. CLINICAL TRIAL REGISTRATION: Does spinal anesthesia for prolapse surgery with concomitant sling lead to an increase in urinary retention compared to general anesthesia? https://clinicaltrials.gov/ct2/show/NCT02547155?term=laura+martin&rank=3 (NCT02547155).

Does spinal anesthesia lead to postoperative urinary retention in same-day urogynecology surgery? A retrospective review.

INTRODUCTION AND HYPOTHESIS: Spinal anesthesia has been reported to be a risk factor for postoperative urinary retention (POUR) in various surgical specialties. We hypothesized that spinal anesthesia was a risk factor for POUR after outpatient vaginal surgery for pelvic organ prolapse (POP). METHODS: This was a retrospective review of an urogynecology database for all outpatient POP vaginal surgeries performed in 2014 to evaluate the risk of POUR after general versus spinal anesthesia. A standardized voiding trial was performed by backfilling the bladder with 300 ml of saline. A successful trial was achieved if the patient voided two-thirds of the total volume instilled, confirmed by bladder ultrasound. Our primary outcome was to compare POUR requiring discharge with a Foley catheter between spinal and general anesthesia. Multivariate logistic regression was performed for variables with significance at p < 0.1 at the bivariate level. RESULTS: A total of 177 procedures were included, 126 with general and 51 with spinal anesthesia. The overall POUR rate was 48.9%. Type of anesthesia was not a risk factor for POUR. Multivariate logistic regression demonstrated that age < 55 years (adjusted odds ratio [OR] 3.73; 95% confidence interval [CI], 1.31-11.7), diabetes (adjusted OR 4.18, 95% CI 1.04-21.67), and having a cystocele ≥ stage 2 (adjusted OR 4.23, 95% CI 1.89-10) were risk factors for developing POUR. CONCLUSIONS: Acute urinary retention after outpatient vaginal pelvic floor surgery can vary by procedure, but overall is 48.9%. Spinal anesthesia does not contribute to POUR, but rates are higher in those women that are younger than 55 years of age, have a cystocele ≥ stage 2 preoperatively, and a history of diabetes.

Development and Validation of a Simulation Model for Laparoscopic Colpotomy.

OBJECTIVE: To develop a realistic simulation model for performance of laparoscopic colpotomy and evaluate its construct and face validity. METHODS: A simulation model was developed and constructed using polyvinyl chloride piping, a uterine manipulator, and synthetic vaginal tissue paired with a commercially available laparoscopic trainer. An observational study was conducted to validate the simulation model for use as a teaching tool. Construct validity was measured through performance evaluation of novice and expert surgeons using a standard and modified Global Operative Assessment of Laparoscopic Skills scale with possible score ranges of 5-25 and 5-40, respectively. Expert surgeons included attending surgeons across various gynecologic subspecialties who teach total laparoscopic hysterectomy to trainees and perform more than 50 total laparoscopic hysterectomies annually. Novice surgeons included residents who perform total laparoscopic hysterectomy as part of their training. Standards were set using a modified contrasting groups approach. Interrater reliability was calculated using Kendall's τ correlation coefficient. Participants were surveyed regarding the realism of the model and its utility as a teaching tool to assess face validity. RESULTS: Five expert and 15 novice surgeons volunteered to participate. Expert surgeons scored higher than novice surgeons on the Global Operative Assessment of Laparoscopic Skills scale (22.8±1.52 vs 13.53±2.69, respectively) with a mean difference of 9.27 (95% CI 7.12-11.4, P<.01) and on a modified Global Operative Assessment of Laparoscopic Skills scale (36.9±2.19 vs 22.6±3.95, respectively) with a mean difference of 14.30 (95% CI 11.2-17.4, P<.01). Suggested passing range was set at 30.5-32.5 out of 40 total points. Kendall's τ interrater reliability was 0.86 (95% CI 0.798-0.923) and 0.87 (95% CI 0.818-0.922), respectively. All participants agreed that the training model was useful for teaching and learning laparoscopic colpotomy and for assessing the learner's ability to perform colpotomy before live surgery. CONCLUSION: This validated simulation system offers novice surgeons an opportunity to practice the skill set necessary to perform laparoscopic colpotomy efficiently and may be used as an educational tool.

Pelvic floor muscle weakness: a risk factor for anterior vaginal wall prolapse recurrence.

INTRODUCTION AND HYPOTHESIS: Native tissue vaginal repairs are associated with relatively high levels of recurrence. Systematic reviews have noted that preoperative pelvic floor muscle strength was associated with increased risk of recurrence in the short term. METHODS: This is a retrospective review of patients who underwent a primary reconstructive surgery for anterior compartment vaginal prolapse between 2001 and 2015. Patients were divided into "absent," "weak" and "good" preoperative PFM strength (aPFM, wPFM and gPFM, respectively) based on a modified Oxford scale. Failure rates were determined by a composite of subjective and objective anatomic outcomes. Subjects who underwent re-operations or procedures for recurrent prolapse of the anterior compartment were considered failures. A p value < 0.05 was considered statistically significant. RESULTS: Two hundred ninety-nine patients were included. The aPFM (n = 36), wPFM (n = 115) and gPFM (n = 148) groups had similar descriptive statistics, except subjects in the aPFM and wPFM groups were significantly older than the gPFM group (p = 0.008). All groups underwent similar reconstructive surgeries. Average length of follow-up of 143.9 weeks (41 to 717 weeks) was similar among the three groups (p = 0.472). For the primary outcome of composite failure, aPFM had significantly more anterior vaginal wall recurrences than both the wPFM and gPFM groups, 13.89% vs. 3.48% and 4.05%, respectively (p = 0.033). CONCLUSIONS: Patients with preoperative absent pelvic floor muscle strength (nonfunctioning PFM) had a significantly higher anterior vaginal wall recurrence rate than those with weak or good pelvic floor muscle strength.

Advanced uterovaginal prolapse: is vaginal hysterectomy with McCall culdoplasty as effective as in lesser degrees of prolapse?

INTRODUCTION AND HYPOTHESIS: There is a paucity of data on the success of vaginal surgery for severe prolapse. The authors hypothesized that the success rates of total vaginal hysterectomy (TVH) with McCall culdoplasty in women with advanced pelvic organ prolapse (POP) and in women with less severe POP are similar. METHODS: This was a retrospective review of women undergoing TVH with McCall culdoplasty from 2005 to 2014. Advanced POP was defined as exteriorized uterovaginal prolapse with Pelvic Organ Prolapse Quantification (POP-Q) point C, Ba or Bp ≥50% of the total vaginal length. The primary aim was to compare surgical success of TVH with McCall culdoplasty for the repair of advanced POP and less severe POP at ≥1 year. RESULTS: A total of 311 women were included, 38 with advanced POP and 273 with less severe POP. Women with advanced POP were older (71.6 vs. 61.8 years, respectively; p < 0.0001), but there were no significant differences in the length of follow-up (102.5 vs. 117 weeks, p = 0.2378), success rates (76.3% vs. 68.5%, p = 0.3553) or reoperation rates (2.6% vs. 4%, p > 0.9999) between women with advanced POP and less severe POP, respectively. There was a higher failure rate in the anterior compartment in those with advanced POP (18.4% vs. 6.2%, p = 0.0168), but not in the apical or posterior compartment. CONCLUSIONS: TVH with McCall culdoplasty is equally effective for the treatment of advanced uterovaginal prolapse as for the treatment of less severe POP. Surgeons should consider this traditional surgery for their patients even if they have high-stage uterovaginal prolapse.

Transvaginal Repair of Complex Rectovaginal Fistulas Using the Porcine Urinary Bladder Matrix as an Augmenting Graft.

BACKGROUND: After the US Food and Drug Administration issued a safety warning concerning vaginal mesh implants in 2008, their use in correction of pelvic floor defects have decreased in the United States (http://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/ucm479732.htm). However, we are still treating patients who have had complications associated with their use, rectovaginal fistulas (RVFs) being one of them. Rectovaginal fistulas are considered complex if greater than 2.5 cm, recurrent, associated with inflammatory bowel disease, or if they are proximal in location. Various surgical techniques have been described for treating RVFs. Interposition grafts such as Martius, gracilis, omental J flaps, and rectus abdominis flaps have been used extensively in correcting RVFs (Am J Gastroenterol 2014;109(8):1141-1157). However, these techniques may increase morbidity or have poor cosmesis. Pelvic surgeons have chronicled the use of biologic grafts for fistula repair. Of the various biologic grafts in use, there have been no reports describing the use of porcine urinary bladder matrix (UBM) for fistula repair. We report on 2 cases of large, complex RVFs secondary to mesh erosion, which were effectively treated with transvaginal repair using the UBM. CASES: An 80-year-old woman was referred by the colorectal service to our urogynecology service with complaints of rectal bleeding and vaginal spotting secondary to mesh erosion. Surgical history included hysterectomy with mesh augmented posterior repair with synthetic midurethral sling placement in 2002. Examination revealed a 3-cm mesh exposure located in the middle third of the posterior vaginal wall. On rectovaginal examination, a 3-cm full-thickness RVF with through-and-through mesh erosion was noted between the rectum and vagina.A 65-year-old woman presented to our service with complaints of passage of fecal material through the vagina. Surgical history was significant for hysterectomy in 1988 and prolapse repair with anterior and posterior vaginal mesh in 2009. Subsequently in 2011, she had part of the mesh removed because of exposure. Vaginal examination revealed mesh exposure at the right sulcus of the anterior wall consistent with evidence of prior sling and another mesh exposure on the posterior vaginal wall. Rectovaginal examination revealed palpable mesh in the rectovaginal septum with a 3-cm large and complex fistula. Both of our patients underwent transvaginal excision of mesh, RVF repair, and posterior repair with augmentation with UBM. At 6- and 10-month follow-up, they reported complete resolution of their symptoms with no fistula noted on physical examination. CONCLUSIONS: Typically, traditional repair with use of muscular advancement flaps is performed for complex RVF closures. Recently, however, various biologic agents have been successfully used to augment RVF repair. In our cases, the use of UBM led to successful follow-up at 6 to 8 months. Despite existing literature, there remains a void in the depth of knowledge regarding the UBM grafts. Larger studies utilizing it for repair of RVFs are warranted to further understand the success and effectiveness of the UBM grafts for RVF repair.

Transobturator versus single incision slings: 1-year results of a randomized controlled trial.

INTRODUCTION AND HYPOTHESIS: To compare 1-year surgical outcomes following transobturator (TO) sling placement and single incision (SI) sling placement for the treatment of stress urinary incontinence (SUI). METHODS: We performed a randomized trial at a single institution. Patients with urodynamically proven SUI were offered participation and randomized to placement of a TO sling (Monarc™) or a SI sling (MiniArc™) between 2008 and 2011. The primary outcome measure was urinary leakage during standardized cough stress test (CST). Forty subjects in each group were required to achieve 80 % power to detect an effect size of 0.25. RESULTS: A total of 98 patients were randomized with 49 patients in the TO group and 49 patients in the SI group. Preoperative demographics were similar between the groups (Table 1). The TO group had a significantly longer sling operative time (10.7 ± 4.8 min vs. 7.8 ± 4.9 min, p < 0.001) and greater estimated blood loss (31.6 ± 26.6 mL vs. 22.9 ± 22.1 mL, p = 0.02). At the 1-year follow-up, there was no difference in the primary outcome with 9 TO patients (21 %) and 12 SI patients (29 %) having a positive CST (p = 0.5). A composite measurement of 'failure', defined as patient-reported SUI and a positive CST, showed no difference between the TO group (17 %) and the SI group (27 %; p = 0.3). CONCLUSIONS: The SI sling provides comparable objective efficacy to the TO sling at 1 year.

De novo stress urinary incontinence after pelvic organ prolapse surgery in women without occult incontinence.

INTRODUCTION AND HYPOTHESIS: There is a paucity of data evaluating the risk of de novo stress urinary incontinence (SUI) after surgery for pelvic organ prolapse (POP) in women with no preoperative occult SUI. We hypothesized that apical suspension procedures would have higher rates of de novo SUI. METHODS: This was a retrospective database review of women who had surgery for POP from 2003 to 2013 and developed de novo SUI at ≥6 months postoperatively. Preoperatively, all patients had a negative stress test and no evidence of occult SUI on prolapse reduction urodynamics. The primary objective was to establish the incidence of de novo SUI in women with no objective evidence of preoperative occult SUI after POP surgeries at ≥6 months. RESULTS: A total number of 274 patients underwent POP surgery. The overall incidence of de novo SUI was 9.9 % [95 % confidence interval (CI) 0.07-0.14]. However, the incidence of de novo SUI in those with no baseline complaint of SUI was 4.4 % (95 % CI 0.03-0.1). There was no difference in de novo SUI rates between apical [9.7 % (n = 57)] and nonapical [10.5 %, (n = 217] procedures (p = 0.8482). Multivariate logistic regression identified sacrocolpopexy [adjusted odds ratio (OR) 4.54, 95 % CI 1.2-14.7] and those with a baseline complaint of SUI (adjusted OR 5.1; 95 % CI 2.2-12) as risk factors for de novo SUI. CONCLUSIONS: The incidence of de novo SUI after surgery for POP without occult SUI was 9.9 %. We recommend counseling patients about the risk of de novo SUI and offering a staged procedure.

Are suburethral slings less successful in the elderly?

INTRODUCTION AND HYPOTHESIS: We aimed to evaluate the success of suburethral slings in women ≥70 years of age. METHODS: This was a retrospective cohort study of women who underwent suburethral sling placement. Subjects were separated into three groups: ≤50 years of age (group 1), 51 to 69 years of age (group 2), and ≥70 years of age (group 3). The primary aim was to evaluate success as defined by ≥ improved on a validated patient improvement satisfaction score and a negative postoperative standardized stress test. RESULTS: There were 1,464 subjects. Mean age was 44.51 ± 4.25 (n = 296) for group 1, 60.5 ± 5.28 (n = 680) for group 2, and 77.68 ± 5.41 (n = 488) for group 3. The median follow-up was 26 (6-498) weeks, 45 (6-498) weeks, and 42 (6-543) weeks, for groups 1, 2, and 3 respectively. Multiple logistic regression analysis demonstrated no difference in sling success according to age stratification. Lower success was associated with having had a previous sling (adjusted OR 0.25, 95 % CI 0.12-0.5), having detrusor overactivity (adjusted OR 0.44, 95 % CI 0.28-0.69), and having a history of urge urinary incontinence (UUI) for ≥ 4 years (adjusted OR 0.54, 95 % CI 0.31-0.95). CONCLUSIONS: There is no difference in sling success between the elderly and younger populations. However, those with previous sling surgery or a long standing history of UUI may be at a higher risk of failure.

Resolution of Rectal Prolapse by Vaginal Reconstruction.

BACKGROUND: Rectal prolapse is a disorder of the pelvic floor in which the layers of the rectal mucosa protrude outward through the anus. Surgical repair is the mainstay of treatment. Options include intra-abdominal procedures such as rectopexy and perineal procedures such as the Delorme and Altemeier perineal rectosigmoidectomy. Rectal and vaginal prolapse can often coexist. However, to our knowledge, there are no reported cases of rectal prolapse resolved by the repair of a compressive enterocele abutting the anterior rectal wall through a vaginal approach alone. We present a novel case of rectal prolapse that resolved by correction of the vaginal defect. CASE: A 53-year-old female with prior history of abdominal hysterectomy, presented to the urogynecology clinic with complaints of vaginal bulge, urge urinary incontinence, and rectal bulge on straining with no fecal incontinence for several years. On physical examination, she was found to have stage 2 anterior, posterior, and apical vaginal prolapse and reducible rectal prolapse. Colorectal surgery (CRS) evaluation was requested, which revealed minimal anterior mucosal prolapse on Valsalva with no full-thickness prolapse. Magnetic resonance imaging (MRI) defecogram was performed, which demonstrated a large rectocele, enterocele, and small bowel prolapsing between the rectum and vagina during the evacuation phase, with no rectal prolapse. The decision to proceed with vaginal prolapse surgery without concomitant rectal prolapse repair was made, as the patient had no fecal incontinence, and the degree of rectal prolapse was minimal. On the day of surgery, which was 2 months later, she presented with a 2-cm anterior rectal prolapse with no incontinence. Colorectal surgery was consulted again, but unavailable. After counseling, the patient wished to proceed with her planned surgery. It was felt that correcting the anterior rectocele and enterocele, thereby eliminating the descent of the bowel on the anterior rectal wall, might cause resolution of the rectal prolapse. She then underwent a sacrospinous ligament fixation with mesh through an anterior vaginal approach, enterocele repair, Moschcowitz culdoplasty, and posterior colporraphy. She had an uneventful postoperative course and noted resolution of both vaginal and rectal prolapse. At 54 weeks, she continues without any complaints of rectal prolapse, which was confirmed on physical examination. CONCLUSIONS: Usually, the choice of surgical approach is tailored to each individual based on anatomy, age, comorbidity, and patient factors. Correcting both vaginal and rectal prolapse at the same time with a minimally invasive approach is an advantage to the patient. Restoring the apical, anterior, and posterior vaginal wall anatomy and an enterocele repair through the vaginal route caused resolution of the rectal prolapse. Further research is required as to whether rectal prolapse caused by anterior rectal compression needs an additional procedure or repair of the vaginal prolapse and enterocele alone will suffice.

Dynamic assessment of sling function on transperineal ultrasound: does it correlate with outcomes 1 year following surgery?

INTRODUCTION AND HYPOTHESIS: To correlate dynamic assessment of sling function using 2D and 3D transperineal ultrasound with outcomes following transobturator sling surgery. METHODS: This is an unmatched case-control study of 100 patients who underwent transobturator sling surgery at our center between 2009 and 2012. Group A (n = 50) patients had successful outcomes and group B (n = 50) patients had suboptimal outcomes 1 year following surgery. The patients underwent 2D dynamic and 3D transperineal ultrasound. The two groups were compared with regard to the deformability of the sling on Valsalva, the concordance of urethral movement with the sling, and location of the sling. RESULTS: When compared with group B, group A had a significantly greater number of patients in whom the sling deformed at Valsalva (flat at rest, curving into a c-shape at Valsalva), the urethral movement was concordant with the sling and the sling had a midurethral location (p < 0.0001). In all 17 patients in group B in whom the urethra moved in a concordant manner with the sling (34%), the sling did not deform on Valsalva maneuver and was located proximally. In all 15 patients in group A in whom the sling remained either flat or curved (30%), the urethra moved concordant with the sling and the sling was in midurethral location. CONCLUSIONS: On 2D and 3D transperineal ultrasound, the best outcomes following transobturator sling surgery are associated with concordance of urethral movement with the sling, midurethral location, and deformability of the sling on dynamic assessment.

Intraoperative Cystoscopic Evaluation of Ureteral Patency: A Randomized Controlled Trial.

OBJECTIVE: To compare different modalities to aid in the evaluation of intraoperative ureteral patency on cystoscopy in the postindigo carmine era. METHODS: In a randomized controlled trial, participants undergoing pelvic surgery were randomized into one of four groups: saline distention (control), 10% dextrose distention, oral phenazopyridine, or intravenous sodium fluorescein. Our primary outcome was visibility of the ureteral jets. Secondary outcomes included surgeon satisfaction; adverse reactions including allergies, urinary tract infections, urinary retention, cystoscopy times, and ureteral obstruction; and delayed diagnosis. Participants were followed for 6 weeks. A sample size of 176 participants was planned to demonstrate a 30% difference in the visibility scale. All analyses were performed in an intention-to-treat fashion. RESULTS: From February 25, 2015, through August 2015, 176 participants were enrolled; 174 completed the trial, and two did not undergo intervention. Forty-four participants were included in the phenazopyridine, dextrose, saline, and sodium fluorescein groups. Sodium fluorescein and 10% dextrose resulted in significantly improved visibility and satisfaction when compared with the control group (P<.001 and P=.004, respectively). Dextrose provided the highest satisfaction and phenazopyridine provided lowest, but visibility was not statistically different between the two groups (P=.101). Three ureteral obstructions were identified intraoperatively and none in the postoperative period. Mean total cystoscopy time varied between 4.0 and 4.8 minutes and postoperative urinary retention rate was 50% across all groups. Overall urinary tract infection rate was 24.1%, which was similar between interventions. There were no related adverse events. CONCLUSION: Compared with the control, 10% dextrose and sodium fluorescein resulted in improved visibility and provided significantly more satisfaction in the evaluation for ureteral patency with no considerable increase in operative time or morbidity.

Indications and Complications Associated with the Removal of 506 Pieces of Vaginal Mesh Used in Pelvic Floor Reconstruction: A Multicenter Study.

STUDY OBJECTIVE: Synthetic mesh utilized to treat stress urinary incontinence (SUI) and pelvic organ prolapse (POP) can often result in postoperative complications. The objectives of this study were to determine: 1) the most common indications for mesh removal; 2) the incidences of the removal of specific mesh procedures (such as suburethral sling [SUS], transvaginal mesh [TVM], or sacrocolpopexy); and 3) the idences and types of surgical complications associated with mesh removal. DESIGN: This was a retrospective study. Design Classification: Canadian Task Force II-3. SETTING: Three tertiary referral centers in the United States. PATIENTS: We examined data from all patients at the three centers who underwent surgical removal of synthetic materials from previous SUS, TVM, and sacrocolpopexy procedures for mesh-related complications from 2011 to 2013. INTERVENTION: Patients underwent vaginal, intra-abdominal, and inguinal mesh revisions by cutting, partial removal, or total removal of the mesh for mesh-related complications. MEASUREMENTS AND RESULTS: Overall, 445 patients with complications underwent mesh removal laparoscopically, via groin dissection and/or transvaginally. There were a total of 506 mesh products removed. Of these, 56.5% were slings and 43.5% were for pelvic organ prolapse (POP). Synthetic mesh removed from patients included: transvaginal mesh (TVM) anterior for anterior vaginal prolapse, TVM posterior for posterior vaginal prolapse, sacrocolpopexy mesh, and suburethral slings (SUS) for stress urinary incontinence. Synthetic SUS removed included: retropubic (RPS), transobturator (TOT), and single-incision slings (SIS). TOT was the most common type of sling removed. Patients with a sling who only complained of vaginal pain with or without intercourse underwent a vaginal approach for surgical revision/removal of the sling (86.6%). Patients with an RPS with lower abdominal/suprapubic pain and vaginal pain underwent a vaginal and laparoscopic approach for sling removal (18.4%). Patients with a TOT sling who complained of vaginal and groin pain underwent a vaginal and inguinal approach for sling removal (4.3%). In patients who had POP mesh removal, 42.3% had an anterior TVM, 30.6% had a posterior TVM, 14% had both anterior and posterior TVMs, and 13.1% underwent sacrocolpopexy mesh removal. Complications encountered during mesh revision/removal surgery were: two blood transfusions from complete RPS removal (vaginal and laparoscopic approach), three urethral injuries during TOT sling removal (vaginal approach), two ureteral injuries during anterior vaginal wall mesh removal, and two rectal injuries during posterior vaginal wall mesh removal. All injuries were repaired at the time of mesh removal without recurrence. CONCLUSION: In our study, the most common indication for mesh removal was pain with or without intercourse. The most common mesh procedure resulting in removal was the TOT sling. Use of a vaginal approach only for sling removal had the lowest incidence of intraoperative complications. Laparoscopic RPS removal had the highest incidence of required blood transfusions, anterior TVM had the highest incidence of ureteral injury, and posterior TVM had the highest incidence of rectal injury. Overall, sling, TVM, and sacrocolpopexy mesh removal are safe procedures when performed by experienced surgeons.

Apical sling: an approach to posthysterectomy vault prolapse.

INTRODUCTION AND HYPOTHESIS: This video demonstrates a transvaginal technique for vaginal vault suspension using an apical sling suspended from the sacrospinous ligaments. METHODS: This was a retrospective review of apical sling procedures performed from July 2013 to November 2014. The technique is started by marking the vaginal apex. A posterior dissection is performed and the sacrospinous ligaments are identified after dissection into the pararectal space. A 10-cm piece of monofilament, inelastic polypropylene tape is attached to the underside of the vaginal apex. Polypropylene sutures are placed into the sacrospinous ligament and threaded though the lateral edges of the apical sling and tied down, restoring apical support. Finally, the vaginal epithelium is closed. RESULTS: A total of 67 women underwent an apical sling procedure with 70 % (47/67) completing 6 months follow-up. The subjective cure rate ("cured" or "greatly improved") was 78.7 % and the objective cure rate (anatomical success, defined as apical prolapse stage ≤1) was 100 % (47 patients). CONCLUSIONS: Our apical sling sacrospinous ligament fixation approach is a unique, minimal mesh approach using a tape commonly used for midurethral slings to suspend the vaginal apex. We achieved high anatomical success and patient satisfaction.

The IUGA/ICS classification of synthetic mesh complications in female pelvic floor reconstructive surgery: a multicenter study.

INTRODUCTION AND HYPOTHESIS: The objective was to report patterns of sling and transvaginal mesh-related complications using the IUGA/ICS classification of prosthesis-related complications. METHODS: This was a retrospective chart review of all patients who underwent surgical removal of sling, transvaginal mesh, and sacrocolpopexy for mesh-related complications from 2011 to 2013 at three tertiary referral centers. The International Urogynecological Association (IUGA)/International Continence Society (ICS) classification system was utilized. RESULTS: We identified 445 patients with mesh complications, 506 pieces of synthetic mesh were removed, and 587 prostheses-related complications were classified. 3.7 % of patients had viscus organ penetration or vaginal exposure as their presenting chief complaint and 59.7 % were classified as not having any vaginal epithelial separation or category 1. The most common category was spontaneous pain (1Be: 32.5 %) followed by dyspareunia (1Bc: 14.7 %). The sling group was 20 % more likely to have pain compared with the pelvic organ prolapse (POP) mesh group (OR 1.2, 95 % CI 0.8-1.6). The most commonly affected site (S2) was away from the suture line (49 %). Compared with the sling group, the POP group had a higher rate of mesh exposure, which mostly occurred at the suture line area. The majority of patients presented with mesh-related complications more than 1 year post-insertion (T4; average 3.68 ± 2.47 years). CONCLUSION: Surgeons should be aware that patients with vaginal mesh complications routinely exhibit complications more than 1 year after the implantation with pain as the most common presenting symptom.
