The Use of Acellular Tissue Matrices in Gender-Affirming Surgery: Review of the Literature and Institutional Experience.

Wound healing complications are not uncommon after genital gender-affirming surgery and can pose significant challenges for the reconstructive surgeon. Acellular tissue matrices are products that contain extracellular matrix compounds without living cells and are used to expedite and improve wound healing. Some of these products have been described for a variety of different indications in gender-affirming surgery.  In this paper, the authors present a review of the current literature on the use of acellular tissue matrices in gender-affirming surgery as well as the authors' institutional experience in using these products.

Oral phenazopyridine vs intravesical lidocaine for bladder onabotulinumtoxinA analgesia: a randomized controlled trial.

BACKGROUND: The efficacy of intradetrusor onabotulinumtoxinA injections for the management of idiopathic overactive bladder has been well-established. The injections are typically performed in the office setting using local analgesia, most commonly a 20 to 30-minute intravesical instillation of lidocaine. There are limited data evaluating alternative bladder analgesics. OBJECTIVE: To compare pain scores with preprocedure oral phenazopyridine vs intravesical lidocaine in women undergoing intradetrusor onabotulinumtoxinA injections for idiopathic overactive bladder. STUDY DESIGN: Nonpregnant adult females with idiopathic overactive bladder, scheduled for office injection of 100 units of intradetrusor onabotulinumtoxinA were randomized to either 200 mg of oral phenazopyridine taken 1 to 2 hours preprocedure or a 20-minute preprocedure intravesical instillation of 50 mL of 2% lidocaine. We excluded participants with neurogenic bladders, and those who had received intradetrusor onabotulinumtoxinA injections in the previous 12 months. The primary outcome was pain measured by a 100-mm visual analog scale. Demographic characteristics and overall satisfaction with the procedure were also recorded. Providers answered questions about cystoscopic visualization, ease of procedure, and perception of participant comfort. Prespecified noninferiority margin was set to equal the anticipated minimum clinically important difference of 14 mm. A planned sample of 100 participants, 50 in each treatment arm, provided 80% power to detect noninferiority at a significance level of.05. We performed a modified intention-to-treat analysis and compared variables with the t test or the Fisher exact test. RESULTS: A total of 111 participants were enrolled, and complete data were obtained for 100 participants; 47 participants were randomized to phenazopyridine and 53 to lidocaine. Baseline characteristics did not differ between groups. There were 19.6% and 20.8% of participants in the phenazopyridine and lidocaine groups, respectively, who previously underwent intradetrusor onabotulinumtoxinA injections. The mean postprocedure pain was 2.7 mm lower in the phenazopyridine group than in the lidocaine group (95% confidence interval, -11.3 to 10.7), demonstrating noninferiority. More than 90% of participants in both groups stated that the pain was tolerable. Slightly more participants reported being "very satisfied" in the lidocaine group, although this was not statistically significant (50.0% vs 40.4%; P=.34). Providers reported clear visualization in 89.4% of participants in the phenazopyridine group and in 100% of participants in the lidocaine group (P=.02). Provider perception of participant comfort and overall ease of procedure were not different between groups. Length of time in the exam room was significantly shorter in the phenazopyridine than in the lidocaine group (44.4 vs 57.5 minutes; P=.0003). CONCLUSION: In women receiving intradetrusor onabotulinumtoxinA injections for idiopathic overactive bladder, oral phenazopyridine was noninferior to intravesical lidocaine for procedural pain control. Phenazopyridine is well-tolerated by participants, allows for the procedure to be performed with similar ease, and is associated with shorter appointment times.

Forming Consensus To Advance Urobiome Research.

Urobiome research has the potential to advance the understanding of a wide range of diseases, including lower urinary tract symptoms and kidney disease. Many scientific areas have benefited from early research method consensus to facilitate the greater, common good. This consensus document, developed by a group of expert investigators currently engaged in urobiome research (UROBIOME 2020 conference participants), aims to promote standardization and advances in this field by the adoption of common core research practices. We propose a standardized nomenclature as well as considerations for specimen collection, preservation, storage, and processing. Best practices for urobiome study design include our proposal for standard metadata elements as part of core metadata collection. Although it is impractical to follow fixed analytical procedures when analyzing urobiome data, we propose guidelines to document and report data originating from urobiome studies. We offer this first consensus document with every expectation of subsequent revision as our field progresses.

Patient Preferences and Knowledge Regarding Hysterectomy: A Study from the Fellows' Pelvic Research Network (FPRN)®.

OBJECTIVE: The purpose of this study was to describe preference for and knowledge of hysterectomy routes in women presenting to urogynecology/gynecology clinics throughout the United States and to determine association with health literacy. Our primary aim was preference for hysterectomy route, and secondary aims were knowledge of basic pelvic structures and function, knowledge of various hysterectomy routes, and baseline health literacy level. METHODS: This multicenter, cross-sectional study was conducted through the Fellows' Pelvic Research Network. Patients' preference and knowledge for hysterectomy routes were assessed at initial presentation to the urogynecology/gynecology clinic with an anonymous, voluntary, self-administered questionnaire along with a validated health literacy test (Medical Term Recognition Test). RESULTS: Two hundred four women participated. Forty-five percent of patients were unsure which hysterectomy modality they would choose. Of patients who selected a preferred modality, 50% selected laparoscopic and 33% selected vaginal. Patients indicated that safety was considered highest priority when selecting route. The mean score for "knowledge about gynecology/hysterectomy" was 68%, with the high literacy group scoring higher compared with the low health literacy group (70% vs 60.1%, P = 0.01). More than 50% of patients incorrectly answered knowledge questions related to vaginal hysterectomy. Majority of the respondents had high health literacy (79.4%). CONCLUSIONS: Patients prefer laparoscopic hysterectomy approach, although have limited understanding of vaginal hysterectomy. Higher health literacy levels are associated with increased knowledge of gynecology and hysterectomy routes, but were not found to influence patient preference for hysterectomy route. Overall, patients have limited knowledge of vaginal hysterectomy.

It Takes a Village: The First 100 Patients Seen in a Multidisciplinary Pelvic Floor Clinic.

OBJECTIVE: This study aimed to assess the characteristics of patients assessed and treated at a multidisciplinary pelvic floor program that includes representatives from multiple specialties. Our goal is to describe the process from triaging patients to the actual collaborative delivery of care. This study examines the factors contributing to the success of our multidisciplinary clinic as evidenced by its ongoing viability. METHODS: This is a descriptive study retrospectively analyzing a prospectively maintained database that included the first 100 patients seen in the Program for Abdominal and Pelvic Health clinic between December 2017 and October 2018. We examined patient demographics, their concerns, and care plan including diagnostic tests, findings, treatments, referrals, and return visits. RESULTS: The clinic met twice monthly, and the first 100 patients were seen over the course of 10 months. The most common primary symptoms were pelvic pain (45), constipation (30), bladder incontinence (27), bowel incontinence (23), high tone pelvic floor dysfunction (23), and abdominal pain (23); most patients had more than one presenting symptom (76). The most common specialties seen at the first visit to the clinic included gastroenterology (56%), followed by physical medicine and rehabilitation (45%), physical therapy (31%), female pelvic medicine and reconstructive surgery (25%), behavioral health (19%), urology (18%), and colorectal surgery (13%). Eleven patients were entirely new to our hospital system. Most patients had diagnostic tests ordered and performed. CONCLUSIONS: A multidisciplinary clinic for abdominal and pelvic health proves a sustainable model for comprehensive treatment for patients with pelvic floor dysfunction, including difficulties with defecation, urination, sexual dysfunction, and pain.

Cultivable Bacteria in Urine of Women With Interstitial Cystitis: (Not) What We Expected.

OBJECTIVE: Multiple studies show cultivatable bacteria in urine of most women. The existence of these bacteria challenges interstitial cystitis (IC)/painful bladder syndrome (PBS) diagnosis, which presumes a sterile bladder. The aims of this study were (1) to compare the female bladder microbiomes in women with IC/PBS and unaffected controls and (2) to correlate baseline bladder microbiome composition with symptoms. METHODS: This cross-sectional study enrolled 49 IC/PBS and 40 controls. All provided catheterized urine samples and completed validated questionnaires. A subset of the IC/PBS cohort provided voided and catheterized urine samples. All samples from both cohorts were assessed by the expanded quantitative urine culture (EQUC) protocol; a subset was assessed by 16S rRNA gene sequencing. RESULTS: Of the IC/PBS cohort, 49.0% (24/49) were EQUC positive; in these EQUC-positive samples, the most common urotypes were Lactobacillus (45.8%) and Streptococcus (33.3%). Of the controls, 40.0% were EQUC positive; of these EQUC-positive samples, the most common urotype was Lactobacillus (50.0%). The urotype distribution was significantly different (P < 0.05), as 16% of the IC/PBS cohort, but 0% of controls, were Streptococcus urotype (P < 0.01). Symptom-free IC/PBS participants were less likely to be EQUC positive (12.5%) than IC/PBS participants with moderate or severe symptoms (68.8% and 46.2%) and the control cohort (60%; P < 0.05). CONCLUSION: Lactobacillus was the most common urotype. However, the presence of Lactobacillus did not differ between cohorts, and it did not impact IC/PBS symptom severity. Bacteria were not isolated from most participants with active IC/PBS symptoms. These findings suggest that bacteria may not be an etiology for IC/PBS.

Historic transvaginal meshes and procedures: what did my patient have done?

PURPOSE OF REVIEW: Transvaginal mesh kits were widely used to treat pelvic organ prolapse for over a 10-year period in the early 2000s. Due to safety concerns and FDA regulations, these mesh kits are no longer available for use. Thus, current Obstetricians and Gynecologists are likely to encounter these meshes, but may have no previous experience or exposure to the devices making it difficult to adequately monitor, counsel, and care for patients that underwent these types of procedures. This review highlights the most commonly used transvaginal mesh kit types, provides insight into signs and symptoms related to transvaginal mesh complications, and provides guidance for management of mesh complications. RECENT FINDINGS: Not all transvaginal mesh will give rise to a complication. If complications do occur, treatment options range from conservative observation to total mesh excision. Management must be customized to an individual patient's needs and goals. SUMMARY: Transvaginal mesh kits promised increased durability of surgical repair for pelvic organ prolapse. Safety concerns over time caused these kits to no longer be available for use. Practicing Obstetricians and Gynecologists should be aware of the history of transvaginal mesh and the signs and symptoms of mesh complications.

Microorganisms Identified in the Maternal Bladder: Discovery of the Maternal Bladder Microbiota.

Objective The objective of this study was to characterize the bladder microbiota in pregnancy. Methods A prospective observational study of 51 pregnant women, admitted to a tertiary care hospital, who underwent straight catheterization urine collection or transurethral Foley catheter placement. 16S rRNA gene sequencing and enhanced quantitative urine culture assessed the maternal bladder microbiota with comparisons made to standard urine culture results. Results Enhanced quantitative urine culture and 16S rRNA gene sequencing detected bacteria in the majority of participants. Lactobacillus and Gardnerella were the most commonly detected microbes. In contrast, standard urine culture had a 100% false-negative rate and failed to detect several known or emerging urinary pathogens. Conclusion There are live bacteria in the bladders of most pregnant women. This challenges the definition of asymptomatic bacteriuria.

Outcomes in 450 Women After Minimally Invasive Abdominal Sacrocolpopexy for Pelvic Organ Prolapse.

OBJECTIVE: To report outcomes and complications in approximately 450 women who underwent isolated minimally invasive abdominal sacrocolpopexy (ASC) for the management of pelvic organ prolapse (POP). MATERIAL AND METHODS: We retrospectively reviewed the electronic medical records of women who underwent minimally invasive ASC (laparoscopic ASC [LASC] or robotic ASC [RASC]) for symptomatic POP at Loyola University Chicago Medical Center from 2007 to 2012. Polypropylene mesh was used and the decision to reperitonealize the mesh was left to surgeon discretion. Data collected included demographics, Pelvic Floor Distress Inventory questionnaire, intraoperative and postoperative details, and POP quantification. RESULTS: Four hundred twenty-eight women underwent minimally invasive ASC-232 LASC and 226 RASC. Most women (86%) did not undergo reperitonealization of the mesh. Median follow-up was 13 weeks (range, 2-268 weeks) for complications and 13 weeks (range, 2-104 weeks) for anatomic outcomes.Postoperatively, 88.6% of women had stage 0/I, 10.7% had stage II, and 2 women had stage III POP. Twelve (2.6%) underwent reoperation, 6 for POP (3 posterior repairs, 2 repeat ASC, 1 perineorrhaphy) and 6 for bowel complications. Fourteen women had postoperative bowel complications; half of which resolved with conservative treatment. There were no differences between anatomic and functional outcomes or bowel complications between LASC and RASC. Reoperation rates for bowel complications in women who underwent reperitonealization of the mesh were similar to those who did not (1.5% vs 1.0%, P = 0.86). CONCLUSIONS: Minimally invasive ASC without concomitant vaginal repair is an effective and safe procedure for the surgical management of POP with low rates of reoperation and complications.

Perceptions of posthysterectomy cystoscopy training in obstetrics and gynecology residency programs.

OBJECTIVE: The objective of this study was to characterize the training practices of obstetrics and gynecology (OG) residency programs regarding posthysterectomy cystoscopy. METHODS: Two separate electronic surveys were sent to program directors and residents at American Council of Graduate Medical Education-accredited OG programs. Measures included the type of cystoscopy training available, estimates on indications and how often posthysterectomy cystoscopy is performed, and exposure to female pelvic medicine and reconstructive surgery (FPMRS). RESULTS: Sixty-one (26%) of 235 program directors and 394 (29.7%) of 1325 residents completed the survey. The majority of residents (95%) who received training reported having experience with cystoscopy in the operating room. Residents with FPMRS fellowships were more likely to perform routine cystoscopy after hysterectomy during their training compared with residents without fellowships (39% vs 27%, P = 0.01). Residents graduating from programs with FMPRS fellowships reported they planned to always perform routine cystoscopy more often than did those without a fellowship program (30.3% vs 17%, P = 0.01).Program directors most frequently defined competency as direct observation of the procedure (95%), followed by the number performed (53%) and a competency checklist (45%). No significant differences were noted in the reported use of routine cystoscopy by program directors after hysterectomy, with or without a fellowship program (62% vs 48%, P = 0.38). CONCLUSIONS: Residents in OG programs are receiving cystoscopy training, most commonly in the operating room, less often with simulation. Nineteen percent reported receiving no training. Graduating residents exposed to FPMRS fellowships more frequently reported planning to always perform cystoscopy after hysterectomy than did those without fellowship exposure.
