Abstract This is a single Institute, prospective cohort study. We collected twenty- two postmenopausal women with pelvic organ prolapse planning to undergo vaginal hysterectomy with transvaginal pelvic reconstructive surgery, with or without a concomitant anti-incontinence procedure. Vaginal swabs and urine samples were longitudinally collected at five time points: preoperative consult visit (T1), day of surgery prior to surgical scrub (T2), immediately postoperative (T3), day of hospital discharge (T4), and at the postoperative exam visit (T5). Women experiencing urinary tract infection symptoms provided a sample set prior to antibiotic administration (T6). Microbiome analysis on vaginal and urinary specimens at each time point. Region V3-V5 of the 16S ribosomal RNA gene was amplified and sequenced. Sample DNA was analyzed with visit T1, T2, T5 and T6. Six (27.3%) participants developed postoperative urinary tract infection whose vaginal sample at first clinical visit (T1) revealed beta-diversity analysis with significant differences in microbiome structure and composition. Women diagnosed with a postoperative urinary tract infection had a vaginal microbiome characterized by low abundance of Lactobacillus and high prevalence of Prevotella and Gardnerella species. In our cohort, preoperative vaginal swabs can predict who will develop a urinary tract infection following transvaginal surgery for pelvic organ prolapse.

A wide variety of fistulae occur in the female pelvis, most of which cause significant morbidity. Diagnosis, characterization, and treatment planning may be difficult using traditional imaging modalities such as fluoroscopy and computed tomography. To date, there is no comprehensive literature review of the radiologic findings associated with various types of female pelvic fistulae, and furthermore, none dedicated to magnetic resonance imaging (MRI). In this article, we seek to provide a broad overview of the MRI characteristics of female pelvic fistulizing disease in combination with epidemiologic and clinical characteristics. MRI is often considered the imaging modality of choice for evaluation of fistulae owing to its superior soft‐tissue contrast and ability to provide surgeons with the highest quality information derived from just one study, including anatomic location of fistulae and associated pelvic pathology. In other instances, MRI can be complementary to the more traditional imaging techniques. This review will describe the etiology, anatomy, MRI findings, and treatment pearls for several of the more common pelvic fistulae found in female patients, including anovaginal, rectovaginal, colovaginal, vesicovaginal, colovesical, and other complex fistulae.Level of Evidence: 5Technical Efficacy: Stage 3J.

INTRODUCTION: The number of applicants to Obstetrics and Gynecology subspecialty fellowships is projected to increase; however, it is known that the interview process is taxing for both applicants and the programs they attend. Concerns include excessive time away from work, cost, lack of coordination for regional travel, and overlapping interview dates. Little is known about applicant preferences for interviewing. METHODS: An e-mail link to a survey designed using web-based tool SurveyMonkey was sent to all residency directors for distribution to fourth year residents at ACGME-accredited Obstetrics and Gynecology programs in the United States. RESULTS: A total of 190 residents responded, 138 of whom applied to fellowship in 2016. Applicants were predominantly female (73.6%), Caucasian (78.3%), married (76.7%), and without children (74.4%). Most (81.3%) were from an academic program. Applicants attended a mean of 10.9 interviews; the most common reason to cancel was conflict with another interview (72.3%). Saturday was the most preferred interview day (46.7%). The majority of applicants preferred half-day interviews (93.2%), and 61.0% preferred an 0800 start to earlier or later times. A pre-interview dinner was favored (64.4%) with work restraints being the largest barrier to attendance. Personal days granted for interviews varied by program from zero (16.1%) to greater than 11 (25.0%). Vacation and unpaid leave were utilized by 56.5% and 9.0% respectively. CONCLUSION: Interviewing for fellowship is a burdensome process, but it could be improved by implementing regional coordination, shorter interview days and weekend interview dates. Gathering information from applicants and fellowship directors can help further streamline the process.

Objectives Rectovaginal fistulae (RVF) often represent surgical challenges, and treatment must be individualized. We describe outcomes after primary surgical repair stratified by fistula etiology and surgical approach. Methods This retrospective cohort study included women who underwent surgical management of RVF at a tertiary care center between July 1, 2001 and December 31, 2013. Cases were stratified according to the following etiology: cancer (RVF-C), inflammatory bowel disease or infectious (RVF-I), and other (RVF-O). Patients with prior surgical treatment of RVF were excluded. Surgical approaches included local (seton, plug), transvaginal or endorectal, abdominal, diversion alone, or definitive (completion proctocolectomy with permanent colostomy or pelvic exenteration). Recurrence-free survival was estimated using the Kaplan-Meier method, and comparisons between subgroups were evaluated based on fitting Cox proportional hazards models. Censoring occurred at last relevant clinical follow-up. Factors contributing to recurrence-free survival were evaluated including age, body mass index, smoking status, fistula etiology, ileostomy, and surgical approach. Results During the study period, 107 women underwent surgical repair of RVF. The most common fistula etiology was RVF-I (54.2%), followed by RVF-O (23.4%), and RVF-C (22.4%). Ninety-four women underwent fistula repair by the local (29.9%), transvaginal/endorectal (25.2%), abdominal approach (19.6%), or diversion alone (13.1%), whereas 13 underwent definitive surgery (12.2%). Recurrence-free survival was significantly different depending on surgical approach ( P < 0.001), but not etiology ( P = 0.71). Recurrence-free survival (95% confidence interval) at 1 year after surgery was 35.2% (21.8%–56.9%) for the local approach, 55.6% (37.0%–83.3%) for the transvaginal or endorectal approach, 95% (85.9%–100%) for the abdominal approach, and 33.3% (15%–74.2%) for those with diversion only. Conclusions Recurrence rates after RVF repair are high and did not differ by fistula etiology. Abdominal repair of RVF had significantly fewer recurrences.
