Robotic Vaginal Hernia Repair for Recurrent Vaginal Prolapse Status Post-Radical Cystectomy with an Indiana Pouch.

INTRODUCTION AND HYPOTHESIS: Pelvic organ prolapse following a radical cystectomy is challenging to treat and recurrence of prolapse after primary repair is common owing to compromised pelvic floor support and tissue quality. Vaginal prolapse repairs are often preferred because of concern for patients' complex intraabdominal pathological conditions. However, for those with recurrent prolapse following colpocleisis, limited definitive treatment options exist. METHODS: This surgical video presents a 64-year-old G4P4 with a history of radical cystectomy with an Indiana Pouch for invasive urothelial carcinoma who presented with recurrent stage IV vaginal prolapse two years following colpocleisis. Owing to thin vaginal tissue, a sacrocolpopexy with vaginal mesh could not be performed, thus, the patient underwent robotic-assisted vaginal hernia repair with a polypropylene-reinforced ovine tissue matrix attached to Cooper's ligament and the levator ani muscles. RESULTS: The surgery was free from complications and her postoperative Pelvic Organ Prolapse Quantification examination revealed a leading vaginal tissue remnant at the level of the hymen. The patient reported overall improved health and quality of life following surgery and recovery on postoperative validated questionnaires. CONCLUSIONS: Vaginal and pelvic floor hernia repair with a polypropylene-reinforced tissue matrix is a feasible definitive surgical treatment for patients with prior radical cystectomy in whom colpocleisis has failed.

Proximity of percutaneous tibial nerve stimulation needle insertion to surrounding anatomic structures: a cadaveric study.

BACKGROUND: Percutaneous tibial nerve stimulation is a third-line treatment for overactive bladder and urgency urinary incontinence. During the procedure, a needle is inserted cephalad to the medial malleolus and posterior to the tibia. In recent years, permanent implants and leads have been developed for insertion into the medial ankle via a small incision. There are many important structures present in the medial compartment of the ankle, including the great saphenous vein, saphenous nerve, tibial nerve, posterior tibial vessels, and tendons of the posterior compartment leg muscles. OBJECTIVE: The primary objective of this study was to identify the proximity of the percutaneous tibial nerve stimulation needle placed per Food and Drug Administration-approved device instructions to nearby important anatomic structures. The secondary objectives were to identify the proximity of the tibial nerve to the needle site, identify clinically relevant ankle anatomic structures, and confirm the tibial nerve and posterior tibial vasculature by histologic analysis. STUDY DESIGN: Detailed medial ankle dissections were performed bilaterally on 10 female lightly embalmed anatomic donors (cadavers) obtained from the Willed Body Program at the University of Louisville. A pin was inserted at the percutaneous tibial nerve stimulation needle site, and the medial ankle was minimally dissected so the surrounding anatomic structures were visible but not disrupted. The shortest distance from the pin to the selected structures of the medial ankle region was measured. On completion of each dissection and set of measurements, tissue was harvested for histologic examination. The distances between the pin and each structure were assessed using means and standard deviations. A paired t test was used to assess the difference in the locations between the left and right ankles. Statistical analysis was performed on left-sided, right-sided, and combined measurements. An 80% prediction interval was found to represent the expected range of values for the measurement of a new cadaver or patient, and the 95% confidence interval of the mean was computed to characterize the average distance across all cadavers or patients. RESULTS: The medial ankle of 10 adult female lightly embalmed cadavers were examined bilaterally. Dissections were completed from October 2021 to July 2022. Of note, 80% prediction intervals for the tibial nerve, the posterior tibial artery or vein, and the flexor digitorum longus tendon had a lower range of 0.0 mm from the pin and extending to 12.1, 9.5, and 13.9 mm, respectively. Moreover, 2 of the structures were found to be asymmetrical between the right and left ankles. The great saphenous vein was further from the pin on the left (20.5 mm [standard deviation of 6.4 mm] on the left vs 18.1 mm [standard deviation of 5.3 mm] on the right; P=.04). The calcaneal (Achilles) tendon was further from the pin on the right side (13.2 mm [standard deviation of 6.8 mm] vs 7.9 mm [standard deviation of 6.7 mm]; P=.04). Tibial neurovascular structures were confirmed with microscopic analysis. CONCLUSION: The anatomic structures within the medial ankle lie unexpectedly close to the percutaneous tibial nerve stimulation needle site as noted per Food and Drug Administration-approved device instructions. There is a possibility that some medial ankle structures are not symmetrical. It is crucial that practitioners understand medial ankle anatomy when performing percutaneous tibial nerve stimulation or permanent device insertion.

General anesthesia versus regional anesthesia in patients undergoing obliterative vaginal procedures for pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: The objective was to compare outcomes in patients receiving general versus regional anesthesia when undergoing obliterative vaginal surgery for pelvic organ prolapse. METHODS: Obliterative vaginal procedures performed from 2010 to 2020 were identified in the American College of Surgeons National Surgical Quality Improvement Program database using Current Procedural Terminology codes. Surgeries were categorized into general anesthesia (GA) or regional anesthesia (RA). Rates of reoperation, readmission, operative time, and length of stay were determined. A composite adverse outcome was calculated including any of the following: nonserious or serious adverse events, 30-day readmission, or reoperation. Propensity score-weighted analysis of perioperative outcomes was performed. RESULTS: The cohort included 6,951 patients, of whom 6,537 (94%) underwent obliterative vaginal surgery under GA and 414 (6%) received RA. When comparing outcomes under the propensity score-weighted analysis, operative times were shorter (median 96 vs 104 min, p<0.01) in the RA group versus GA. There were no significant differences between composite adverse outcomes (10% vs 12%, p=0.06), or readmission (5% vs 5%, p=0.83) and reoperation rates (1% vs 2%, p=0.12) between the RA and GA groups. Length of stay was shorter in patients receiving GA than in those receiving RA, especially when undergoing concomitant hysterectomy (67% discharged within 1 day in GA vs 45% in RA, p<0.01). CONCLUSIONS: Composite adverse outcomes, reoperation rates, and readmission rates were similar in patients who received RA for obliterative vaginal procedures compared with GA. Operative times were shorter in patients receiving RA than in those receiving GA, and length of stay was shorter in patients receiving GA than in those receiving RA.

Video Playback as an Educational Tool for Improving Resident Laparoscopic Performance: A Randomized Controlled Trial.

STUDY OBJECTIVE: In this single-masked randomized controlled study, we evaluate whether watching video recordings of oneself performing Fundamentals of Laparoscopic Skills (FLS) exercises results in an improvement on the 30-point Global Operative Assessment of Laparoscopic Skills (GOALS) assessment among Obstetrics and Gynecology (Ob/Gyn) residents. DESIGN: Twenty-three Ob/Gyn residents in the 2020-2021 academic year completed the FLS exercises while being timed, video recorded, and receiving real-time feedback from an Ob/Gyn faculty member. Baseline GOALS assessment was completed by participants and faculty. After the intervention, all participants then repeated the FLS exercises while being timed and were again scored using the GOALS assessment. Each participant completed the study in a single session. In addition, all participants completed a pre- and post-test survey. SETTING: University of Louisville Laparoscopic Skills Labortaory. PARTICIPANTS: University of Louisville Ob/Gyn residents in the 2020-2021 academic year. INTERVENTION: Twelve participants were randomized to the intervention and were allowed to watch their video recording in addition to receiving verbal feedback whereas the remaining 11 received verbal feedback only. MEASUREMENTS AND MAIN RESULTS: There were significant improvements in faculty (p <.01) and self-reported GOALS scores (p <.01) when comparing both the intervention and control group with baseline scores. The intervention group improved by 3.2 points more than that of the control group based on masked faculty evaluation (95% confidence interval, 1.4-5.0 points; p <.01). The difference was not significant in resident self-scores. Overall time improved for all participants (15:54 ± 0.21 minutes before and 13:13 ± 0.14 minutes after), but this difference was not significant between the 2 groups. Higher postgraduate year (PGY) residents reported significantly more comfort performing laparoscopic tasks, earned higher GOALS score (faculty and self-scores), and completed the first set of exercises in less time. A significant interaction between PGY and intervention was detected with improvement in GOALS score most strongly associated with PGY4 residents (p <.01). CONCLUSION: Although all learners objectively benefit from watching recordings of themselves performing surgical tasks, advanced learners may benefit the most when video recordings are used as an educational tool.

Robotic sacrohysteropexy: an instructional video for uterovaginal prolapse repair in patients with desired uterine preservation.

INTRODUCTION: Minimally invasive sacrohysteropexy is a feasible and safe option for the treatment of uterovaginal prolapse in patients with prior sacrorectopexy. This video demonstrates an approach to robotic sacrohysteropexy while also adapting for a patient's prior sacrorectopexy. Sacrohysteropexy has been shown to be a viable option in women undergoing pelvic reconstructive surgery for the repair of uterovaginal prolapse. METHODS: This video demonstrates key steps in performing a robotic sacrohysteropexy without compromising the integrity of the patient's prior sacrorectopexy. First, incision and dissection of the anterior and posterior peritoneum overlying the cervical stroma is carried out. Tunnels are made through the avascular plane of the broad ligament lateral to the uterine vessels, so as not to compromise uterine blood supply. The anterior and posterior arms of the mesh are attached with interrupted sutures to the cervical stroma. The presacral space is entered and dissected such that the anterior longitudinal ligament is exposed. Care is taken not to disrupt the sutures from the prior sacrorectopexy as the sacral arm of the mesh is secured with two interrupted stitches. CONCLUSION: At completion of the procedure the patient had a well-supported apical compartment.

Shifts in Vaginal Bacterial Community Composition Are Associated With Vaginal Mesh Exposure.

OBJECTIVE: The objective of this study was to evaluate the relationship between vaginal mesh exposure and vaginal bacterial community composition. METHODS: Vaginal swab samples were collected from 13 women undergoing excision of vaginal mesh with vaginal mesh exposure. Samples were collected at the midvagina, site of exposure, and underneath the vaginal epithelium at the exposure. Control samples were collected vaginally during 15 new patient examinations. For all samples, we extracted genomic DNA and polymerase chain reaction amplified and sequenced the 16S rRNA gene V4 region. We tested for differences in the microbiota among control and exposure samples with PERMANOVA tests of beta diversity measures (Morisita-Horn dissimilarity) and Wilcoxon rank sum tests of Lactobacillus distribution. RESULTS: Vaginal bacterial communities in both control and case groups were divided into 2 primary community types, one characterized by Lactobacillus dominance (>50% of community) and the other by low Lactobacillus and a high diversity of vaginal anaerobes. In 10 of 13 case women, bacterial communities were highly similar between the 3 vaginal sites (adonis R2 = 0.86, P = 0.0099). In the 3 women with community divergence, all 3 were characterized by decreased Lactobacillus abundance at the exposure site. Overall, Lactobacillus abundance was lower at the site of mesh exposure and under the epithelium than in the experimental control (W = 137, P = 0.072, r = 0.41; W = 146, P = 0.025, r = 0.50). Common putative pathogenic mesh colonizing bacteria were common (in 51 of 54 samples), but generally not abundant (median relative abundance = 0.014%). CONCLUSIONS: In vaginal mesh exposure cases, a woman is more likely to have a diverse, non-Lactobacillus-dominant community.

Bladder Instillations With Triamcinolone Acetonide for Interstitial Cystitis-Bladder Pain Syndrome: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the utility of adding triamcinolone acetonide to a standard bladder instillation solution for treatment of interstitial cystitis-bladder pain syndrome. METHODS: This was a single-center, randomized, double-blind trial that compared symptom response in women with interstitial cystitis-bladder pain syndrome who underwent six bladder instillations with triamcinolone acetonide or six instillations without. All instillation solutions contained heparin, viscous lidocaine, sodium bicarbonate, and bupivacaine. The primary outcome was the change in interstitial cystitis-bladder pain syndrome symptoms from the first to sixth bladder instillation between groups based on the total OLS (O'Leary-Sant Questionnaire) score. Assuming a 4.03-point or larger difference in the mean total OLS score from the first to sixth bladder instillation as compared between the groups, 64 participants were needed to show a significant difference with 80% power at the 0.05 significance level. RESULTS: From January 2019 to October 2020, 90 women were enrolled-45 per group; 71 (79%) completed all six bladder instillations. Randomization resulted in groups with similar characteristics. There was no difference between groups in the primary outcome (bladder instillation with triamcinolone acetonide: mean OLS change -6.7 points, 95% CI 4.6-8.8 and bladder instillation without triamcinolone acetonide: mean OLS change -5.8 points, 95% CI 3.4-8.1; P=.31). Women in both groups had improvement in their interstitial cystitis-bladder pain syndrome symptoms as indicated by a decrease in the total OLS score from the first to sixth bladder instillation. CONCLUSION: The addition of triamcinolone acetonide to a standard bladder instillation solution does not improve symptoms associated with interstitial cystitis-bladder pain syndrome. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT03463915.

Comparative analyses of attitude, knowledge, and recollection of preoperative counseling regarding pelvic mesh among women with or without a mesh-related complication.

PURPOSE: Our objective was to compare the recollection of preoperative counseling regarding mesh for pelvic organ prolapse (POP) and/or stress urinary incontinence (SUI) among women with or without a mesh-related complication (MRC). We hypothesized that the patients who had MRC would better recollect counseling regarding complications associated with mesh. METHODS: We conducted a retrospective cohort study among women who had prior implantation of synthetic, non-absorbable mesh for POP and/or SUI at least 3 months prior who presented with or without a MRC. The primary outcome was the proportion of women who recalled being counseled preoperatively about the risk of mesh exposure. RESULTS: Ninety-six women were included in the final analysis (50 MRC; 46 no MRC). MRC women presented further in time from the index surgery [median 69 months [IQR 26-115] vs 12 months (IQR 6-64), p < 0.01]. After adjustment for time since surgery and age, MRC women were significantly less likely to recall being counseled about the possibility of any MRC [19/50 (38%) vs 32/44 (73%), aOR 0.29, 95% CI 0.11-0.79, p = 0.01]. They were also less likely to report they would undergo the same surgery again 5-point Likert scale [median 3 (IQR 1-4) vs 5 (IQR 3-5), 5-point Likert scale, p < 0.01], less satisfied with their mesh surgery [median 1 (IQR 1-3) vs 5 (IQR 3-5), 5-point Likert scale, p < 0.01] and recommended improved preoperative counseling [27/50 (54%) vs 6/46 (13%), p < 0.01]. CONCLUSION: Women who experienced MRC were less likely to recall being counseled about the possibility of MRC and report more unmet needs regarding perioperative counseling than women without MRC.

Learner Satisfaction and Experience With a High-definition Telescopic Camera During Vaginal Procedures: A Randomized Controlled Trial.

OBJECTIVE: The aim of this study was to compare learner satisfaction and experience with a table-mounted, projecting, high-definition telescopic camera system (VITOM) versus traditional learner observation during vaginal surgery. METHODS: Medical student and resident learners were randomized to vaginal surgery observation with or without the use of VITOM. We collected data on learner characteristics and their experience with vaginal surgery. After the surgery, learners completed the faculty/preceptor and working environment domains of the Veterans Affairs Learner's Perceptions Survey (VA LPS). The primary outcome was learners who were "very satisfied" on the VA LPS faculty/preceptor domain. We queried their ability to observe the surgery and satisfaction with learning in the operating room using a 100-mm visual analog scale. RESULTS: Ninety-two learners completed the study (n = 44 VITOM, n = 48 no VITOM). There was no significant difference between groups in the proportion of learners "very satisfied" on the VA LPS faculty/preceptor domain (93.2% VITOM vs 91.5% no VITOM; odds ratio, 1.27; 95% confidence interval, 0.20-9.19; P = 0.99). Learners in the VITOM group were more likely to report ability to see what the main surgeon was doing (93.2% VITOM vs 62.5% no VITOM; odds ratio, 8.02; 95% confidence interval, 2.07-46.32; P < 0.01). Using the visual analog scale, learners in the VITOM group reported higher satisfaction with learning in the operating room (median, 96 [interquartile range, 89-100] VITOM vs median, 80 [interquartile range, 57-98] no VITOM; P < 0.01). CONCLUSION: The use of a table-mounted, projecting, telescopic camera system during vaginal surgery showed no difference in learner satisfaction on validated questionnaires but resulted in improved experience and visualization.

"Landmark" Articles in Female Pelvic Medicine and Reconstructive Surgery: Do We Read What We Cite?

OBJECTIVE: The aim of the study was to describe the provision of a "landmark" article reading list to trainees by their Female Pelvic Medicine & Reconstructive Surgery (FPMRS) fellowship programs. METHODS: In this cross-sectional study, a web-based survey was sent to program coordinators of accredited FPMRS programs. Available reading lists were collected, and a master list compiled. Nonparametric tests were used to investigate the association between the number of faculty members and presence of a reading list. RESULTS: We received a response from 46 (92%) of the 50 Accreditation Council for Graduate Medical Education programs contacted. Half the programs (23/46, 50%) reported that they do not offer a recommended reading list, 5 programs were unsure and over more than 60% with a list (12/18, 67%) shared their list with the investigators. Programs had between 2 and 14 core faculty members with a median (interquartile range) of 4 (3-6). Programs with a reading list had significantly fewer faculty members (3.5, 3-5 vs 5, 3-6, P = 0.03). There were 323 unique articles across the 12 lists, with a median of 25 articles per list. Thirty-four articles were on 4 or more lists; 9 of these (9/34, 26%) have previously been identified as citation classics. CONCLUSIONS: At least 50% of the Accreditation Council for Graduate Medical Education accredited programs do not provide their fellows with a recommended reading list, and fewer core faculty members are associated with the presence of such a list. Although some commonalities are found between reading lists, a universal reading list of "landmark" articles could improve the consistency of FPMRS fellowship education.

Proper assembly of a self-retaining, vaginal Magrina-Bookwalter retractor and demonstration of its use during a vaginal hysterectomy.

INTRODUCTION/AIM OF THE VIDEO: Vaginal surgery often presents challenges of access. To gain adequate visualization of relevant structures, surgical assistants often assume awkward positioning with inadequate stability of handheld retractors. Additionally, the lead surgeon is typically the only member of the surgical team who can adequately visualize the procedure being performed. To that end, devices have been manufactured with aims of optimizing both visualization and workspace while reducing the need of handheld retractors during vaginal surgery. This video presents one of those retractors: a reusable, self-retaining, vaginal Magrina-Bookwalter, with details to help achieve the optimal visualization and workspace with its use. METHODS: A narrated video provides a brief history, components and proper assembly of the retractor with stepwise application of components demonstrated during a vaginal hysterectomy. CONCLUSION: The self-retaining, vaginal Magrina-Bookwalter retractor is a helpful tool to optimize the visualization and workspace while reducing the need for handheld retractors during vaginal procedures deeper into the pelvis.

Association of Patient Race With Type of Pelvic Organ Prolapse Surgery Performed and Adverse Events.

OBJECTIVES: This study aimed to determine if there are differences in (1) surgical procedures performed for pelvic organ prolapse (POP) and (2) rates of adverse events between racial groups. METHODS: We conducted a retrospective cohort study of women 18 years and older who underwent POP surgery using the 2005-2015 American College of Surgeons National Surgical Quality Improvement Program database. Race was categorized as Black, White, Hispanic, and other minority. Pelvic organ prolapse procedures were organized into 4 groups: (1) hysterectomy without concurrent POP procedures, (2) vaginal wall repair(s) only without apical suspension, (3) apical suspension with or without vaginal wall repair(s), and (4) obliterative procedures. Patient characteristics and rates of adverse events were noted. A multivariable logistic regression model was used to assess the association between patient race and surgical procedures performed for POP. RESULTS: We identified 48,005 women who met the inclusion criteria. Most women who underwent POP surgery were White (79.6% [n = 38,191]). Although only contributing to 4.7% (2,299) of the cohort, Black women experienced higher complication rates compared with White women (10.7% [246] for Black vs 8.9% [3,417] for White women, P < 0.01). Hispanic and other minority women were less likely to undergo an apical suspension than White women (adjusted odds ratios [aORs], 0.79 [0.75-0.84] for Hispanic women and 0.78 [0.71-0.86] for other minority women; P < 0.001 for both). Obliterative procedures were more likely to be performed in Black, in Hispanic, and especially in other minority women (aORs, 1.53 [1.20-1.92] for Black, 1.33 [1.12-1.58] for Hispanic, and 3.67 [3.04-4.42] for other minority women; P < 0.001 for all). CONCLUSIONS: Racial differences exist among women who undergo POP surgery.

Candy Cane Compared With Boot Stirrups in Vaginal Surgery: A Randomized Controlled Trial.

OBJECTIVE: To evaluate differences in physical function at 6 weeks after vaginal surgery among women positioned in candy cane and boot stirrups. METHODS: We conducted a single-masked, randomized controlled trial of women undergoing vaginal surgery with either candy cane or boot stirrup use. The primary outcome was a change in the PROMIS (Patient-Reported Outcomes Measurement Information System) physical function short form-20a from baseline to 6 weeks after surgery. To achieve 80% power to detect a moderate Cohen effect (d=0.5), we required 64 participants in each group. RESULTS: From March 2018 to October 2019, 141 women were randomized, and 138 women (72 in the candy cane group and 66 in the boot stirrup group) were included in the final analysis. There were no baseline differences in participant characteristics including age, body mass index, comorbidities, or preoperative history of joint replacements. There were no between-group differences in surgery type, duration of surgery, estimated blood loss, or adverse events at 6 weeks postoperation. Participants in the candy cane group demonstrated worse physical function at 6 weeks compares with the improvement seen in those in the boot stirrup group; this was significantly different between groups (-1.9±7.9 candy cane vs 1.9±7.0 boot, P<.01). CONCLUSION: Women undergoing vaginal surgery positioned in boot stirrups have significantly better physical function at 6 weeks after surgery when compared with women positioned in candy cane stirrups. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT03446950.

The Impact of Fluoroscopy During Percutaneous Nerve Evaluation on Subsequent Implantation of a Sacral Neuromodulator Among Women With Pelvic Floor Disorders: A Randomized, Noninferiority Trial.

OBJECTIVES: To evaluate whether percutaneous nerve evaluation (PNE) without fluoroscopy is inferior to fluoroscopy use in women undergoing trials of sacral neuromodulation (SNM) for pelvic floor disorders (PFDs). MATERIALS AND METHODS: In an unblinded noninferiority trial, women undergoing PNE were randomized to fluoroscopy or no fluoroscopy. The primary outcome was "success" and defined as implantation of the permanent SNM device within three months of PNE. At an expected 40% success and a 30% noninferiority threshold, 33 participants in each group were needed for 80% power (α = 0.05). Univariate analyses and a logistic regression model adjusting for univariate variables associated with the primary outcome were performed. RESULTS: From April 2016 to December 2018, 74 participants underwent PNE of which 36 underwent PNE with fluoroscopy and 38 without. The fluoroscopy group had less baseline mean daily voids compared to the no fluoroscopy group (10.79 ± 6.48 vs. 16.21 ± 10.05, p = 0.01). PNE performed without fluoroscopy had similar success (18/38, 47.4%) compared to fluoroscopy (21/36, 58.3%), meeting our noninferiority definition (difference 10.9%, 90% CI -8% to 30%, p = 0.049). In a logistic regression model adjusting for age, Charlson comorbidity index, stage of prolapse, and number of baseline voids per day, trial success was still similar between the two groups (adjOR 1.82, 95% CI 0.52 to 6.94, p = 0.36). CONCLUSIONS: PNE performed without fluoroscopy is noninferior to PNE with fluoroscopy use for the outcome of SNM device implantation within three months among women undergoing therapy for PFDs.

Development of a safety zone for rectus abdominis fascia graft harvest based on dissections of the ilioinguinal and iliohypogastric nerves.

BACKGROUND: As a result of the vaginal mesh controversy, surgeons are performing more nonmesh, autologous fascia pubovaginal slings to treat stress urinary incontinence in women. The rectus abdominis fascia is the most commonly harvested site for autologous pubovaginal slings, so it is crucial that surgeons are familiar with the relationship between this graft harvest site and the ilioinguinal and iliohypogastric nerves, which can be injured during this procedure. OBJECTIVE: The aims of this study were as follows: (1) to estimate the safest area between the bilateral courses of the ilioinguinal and iliohypogastric nerves in which a rectus abdominis fascia graft could be harvested with minimal risk of injury to these nerves and (2) to determine the location and dimensions of a graft harvest site that maximized graft length while remaining close to the pubic symphysis. STUDY DESIGN: The ilioinguinal and iliohypogastric nerves were dissected bilaterally in 12 unembalmed female anatomical donors. The distances of these nerves to a 10 × 2 cm rectus abdominis fascia graft site located 4 cm above the pubic symphysis were measured. Nerve courses inferior to the graft site were determined for each donor by linearly extrapolating measurement points; analysis was performed with and without extrapolation. Average nerve trajectories were estimated assuming a linear regression function to predict the horizontal measurement as a quadratic function of the vertical distance; 95% confidence bands were also estimated. An estimated safety zone was determined to be the region between all credible nerve bounds. RESULTS: The largest safety zone that was closest to the pubic symphysis was located at 5.4 cm superior to the pubic symphysis. At this location, the inferior border of the graft could measure 9.4 cm in length (4.7 cm bilaterally from the midline). Extrapolated nerve courses below the study graft site yielded a smaller safety zone located 2.7 cm superior to the pubic symphysis, allowing for the inferior border of the graft to be 4.8 cm (2.4 cm bilaterally from the midline). CONCLUSION: A rectus abdominis fascia graft harvested 5.4 cm superior to the pubic symphysis with the inferior border of the graft measuring 9.4 cm in length should minimize injury to the ilioinguinal and iliohypogastric nerves. These dimensions allow for the longest graft while remaining relatively close to the pubic symphysis. The closer a graft is harvested to the pubic symphysis, the smaller in length the graft must be to avoid injury to the ilioinguinal and iliohypogastric nerves.

Cadaveric surgical demonstration of middle to distal ureteral injury repairs in urologic and gynecologic surgeries.

INTRODUCTION AND HYPOTHESIS: Iatrogenic ureteral injuries can occur during any surgery but are more likely to occur during urologic and gynecologic procedures. The middle and distal ureter are especially at risk of injury during these surgeries. METHODS: The objective of this surgical educational video was to demonstrate how to repair middle to distal ureteral injuries with the following techniques: direct ureteroureterostomy, ureteroneocystotomy, vesico-psoas hitch, and Boari-Ockerblad bladder flap. RESULTS: A female cadaver was used to show how to surgically repair injuries to the middle and distal ureter. CONCLUSIONS: Middle to distal ureteral injuries occurring during urologic and gynecologic surgeries can be repaired by the techniques demonstrated in this video manuscript.

Citation classics: the 100 most cited articles in Urogynecology.

INTRODUCTION AND HYPOTHESIS: The objective of this study was to utilize objective citation analyses to describe the 100 most cited articles in the field of Female Pelvic Medicine & Reconstructive Surgery (FPMRS) and to review their characteristics. METHODS: We searched the Thomas Reuters Web of Science database for the most cited articles within all journals classified as Obstetrics and Gynecology (Ob/Gyn), Urology (Uro), Colorectal Surgery (CRS), and vital General Medicine (GM) journals (New England Journal of Medicine; Journal of the American Medical Association; Lancet; The BMJ). We reviewed search results for FPMRS content and compiled a list of the top 100 most cited articles relevant to FPMRS. RESULTS: We screened 34,934 articles yielded by the initial search and compiled the 100 most cited articles relevant to FPMRS. Of these 100 titles, 40% (42 out of 105) were published in Ob/Gyn, 46.7% (49 out of 105) in Uro, 1.9% (2 out of 105) in CRS, and 11.4% (12 out of 105) in GM journals. The most cited FPMRS article was "The standardisation of terminology of lower urinary tract function: report from the Standardisation Sub-committee of the International Continence Society" (3,810 total and 242 citations per year). Over half the articles were observational in nature and the majority (58%) of them were related to urinary incontinence in women. CONCLUSIONS: Highly cited FPMRS articles come from a variety of journals, and nearly 50% of the 100 most cited FPMRS articles are from the urology literature. The most cited articles were largely observational rather than interventional studies and mostly related to female urinary incontinence.
