Case log trends of urogynecology and reconstructive pelvic surgery fellows: A comparison of urology- and gynecology-based fellowship programs.

AIMS: Urogynecology and Reconstructive Pelvic Surgery (URPS) fellowship can be pursued after completion of either a urology (URO) or obstetrics and gynecology (GYN) residency. Our aim is to determine differences in graduating fellow cohort (GFC) case logs between URO- and GYN-based URPS programs. METHODS: Accreditation Council for Graduate Medical Education case logs for URPS GFCs in both GYN- and URO-based programs were analyzed for the 2019-2023 academic years (AY). Unpaired t-tests with Welch's correction were used to compare annual mean logged cases between URO- versus GYN-based GFCs for select surgical categories and the top 11 most logged index cases. RESULTS: GYN-based GFCs logged more cases for all pelvic organ prolapse (POP) categories including surgery on apical POP, anterior wall POP, and posterior wall POP (all p < 0.01), while URO-based GFCs logged more cases for surgery on the urinary system (p = 0.03). For the top 11 logged procedures, URO-based GFCs logged more sacral neuromodulation cases (p = 0.02), whereas GYN-based GFCs logged more slings, vaginal hysterectomies, minimally-invasive hysterectomies, vaginal apical POP, vaginal posterior POP, vaginal anterior POP, and minimally-invasive apical POP cases (all p < 0.01). There was no difference between URO- and GYN-based GFCs for complex urodynamics, cystoscopy with botox injection, or periurethral injection cases. CONCLUSIONS: URO-based URPS fellows tend to graduate with more surgery on the urinary system and sacral neuromodulation cases, while GYN-based fellows perform more slings, hysterectomies, and POP surgery. These findings may help fellowships better understand potential differences in training among graduates from URO- and GYN-based programs and encourage collaboration to lessen these discrepancies.

Female pelvic medicine and reconstructive surgery fellows' case logs remained stable during the COVID-19 pandemic.

INTRODUCTION: During the COVID-19 pandemic and subsequent staffing shortages there was concern about the case volume, and thus competency, of graduating trainees due to reduced surgical volumes. Elective procedures were particularly affected, which includes Female Pelvic Medicine and Reconstructive Surgery (FPMRS) cases. To understand whether FPMRS fellows were affected, we assessed their case logs for changes during the pandemic. METHODS: The nationally aggregated case logs of graduating FPMRS fellows, both urology and obstetrics and gynecology (OBGYN), were obtained from the Accreditation Council for Graduate Medical Education. The available academic years (AYs) included 2018-2019, 2019-2020, and 2020-2021. Standard deviation for each index category was derived from the average and 90th percentile data. One-way analysis of variance was used to compare differences in case volumes for tracked index categories between AYs. RESULTS: Graduating fellows logged an average of 517.4 (standard deviation [SD] 28.6) and 818.0 (SD 37.9) cases, for urology and OBGYN respectively, over their fellowship training during the examined period. No significant differences in total surgical procedures were found for either specialty between pre-COVID AY 2018-2019 and COVID-affected AYs 2019-2020 and 2020-2021. For urology fellows, gastrointestinal (GI) procedures was the only index case category with a significant difference, and it was a decrease between the two COVID-affected AYs: 2020-2021 compared to 2019-2020 (8.9 vs. 4.2, p = 0.04). For both urology and OBGYN fellows, there was a statistically significant decrease in graft/mesh augmentation procedures from COVID-affected AY 2019-2020 to AY 2020-2021. This may be attributed to the reclassification of mesh removal cases from graft/mesh augmentation procedures to genital procedures in 2020-2021. There was not a significant decrease in these procedures from pre-COVID AY 2018-2019 to the COVID-affected AYs. There were no other statistically significant differences between AYs for OBGYN fellows. CONCLUSIONS: Surgical case volumes for FPMRS urology and OBGYN fellows who trained during the COVID-19 pandemic were comparable to those of their pre-pandemic peers. No significant differences between pre-COVID and COVID-affected years were found for either total surgical procedures or index case categories. Despite disruptions in health care nationwide, FPMRS trainee case volumes were largely unaffected.

Are high-risk prostate cancer patients being treated equally? The impact of PSA.

BACKGROUND: Patients with high-risk (HR) prostate cancer (PCa) represent a heterogeneous group, however, current treatment guidelines do not consider their specific features. The objective of this study was to evaluate treatment trends and outcomes in HR patients defined by PSA alone and otherwise low-risk features. METHODS: Using the National Cancer Database, we identified patients diagnosed with HR PCa between 2010 and 2016. A study group of patients defined by PSA >20 ng/ml alone and otherwise low-risk features, was compared to a group of HR patients defined by Gleason score or stage. We compared treatment rates over time, the use of concomitant androgen deprivation therapy (ADT), and overall survival (OS). Examination of treatment trends was done using a Z-test analysis. A Kaplan-Meier survival analysis was used to determine 5-year OS with the Log-rank test for comparison. Statistical analyses were completed using R Version 3.5.2. RESULTS: We identified 5,652 patients in the study group and 71,922 in the comparison group. Only 6.8% of the study group had disease ≥cT2, compared to 43.7% in the comparison group. In the study group, 12.5% (709), underwent active surveillance (AS), 36.4% (2,055) radiation therapy (EBRT) and 51.1% (2,888) radical prostatectomy (RP), while the rate of AS, EBRT, and RP in the comparison group were 0.3% (191), 43.0% (30,928), and 56.7% (40,803), respectively. Over the study period, adoption of AS increased from 6.2% in 2010 to 25.0% in 2016 in the study group (P< 0.001), but not in the comparison group. In patients undergoing EBRT, ADT treatment increased from 2010 to 2016 in both groups, though by 2016 only 45.3% of patients in the study group and 86.3% in the comparison group received ADT. The 5-year OS was 93.7% (95% CI 92.8-94.6) in the study group and 89.7% (95% CI 89.2-90.1) in the comparison group (P< 0.001). CONCLUSIONS: Men with HR PCa defined by PSA with otherwise low risk features present at an earlier stage and receive less aggressive therapy than other HR patients. Despite increased rates of AS and decreased use of ADT, these patients appear to have improved survival when compared to other HR patients. These findings suggest that not all HR patients will benefit from aggressive definitive treatment.

Impact of COVID-19 on Society of Urologic Oncology fellowship operative volumes.

PURPOSE: The COVID-19 pandemic impacted all aspects of healthcare including surgical training. Our objective was to assess the impact of the pandemic on surgical case volumes of graduating Society of Urologic Oncology (SUO) fellows during the academic years 2019 to 2020 and 2020 to 2021. MATERIALS AND METHODS: Deidentified case logs for graduating SUO fellows from 2017 to 2021 were obtained from the SUO Education Committee. Cases are stratified by category and minimally invasive surgery (MIS) or open approach. Graduates of 2017, 2018, and 2019 were combined into a pre-COVID cohort and compared to COVID-affected 2020 and 2021 cohorts. Total case volumes, case category volumes, and surgical approach type were compared with Kruskal-Wallis test. RESULTS: A total of 173 graduating SUO fellow case logs were analyzed with 100, 38, and 35 in the pre-COVID and COVID-affected 2020 and 2021 cohorts, respectively. All fellow logs were obtained for 2017 to 2020 graduates while 5 of 40 were missing for the 2021 cohort. There was no statistical difference in median total cases across cohorts (P = 0.52). For the first COVID-affected cohort of 2020, they reported significantly fewer total MIS cases in 2020 compared to pre-COVID fellows (median 92.5 vs. 135 pre-COVID, P = 0.002). However, there were no significant differences among the tracked oncologic MIS categories except a statistically significant increase in MIS retroperitoneal lymph node dissection between 2020 and 2021 COVID-affected cohorts (0 vs. 2, P = 0.033) CONCLUSIONS: The oncologic case volumes of the initial SUO fellows graduating during COVID pandemic were minimally affected. This national deidentified data is reassuring that oncologic training has not been impacted by widespread decreases in case volume. However, impacts on individuals, programs or geographic regions may have varied.

Robotic Ureteral Reconstruction.

It is generally accepted that robotic ureteral reconstruction provides equivalent results to open and laparoscopic approaches while decreasing pain and length of stay. There is a rapid expansion of robotic ureteral reconstructive techniques, platforms, and adjunctive technologies, enabling more efficient, safer, and novel surgical approaches that could not be done in the past. For instance, indocyanine green use allows rapid, precise location of ureteral stenosis and determination of tissue perfusion. Multi-image display allows the surgeon to integrate the robotic field and ureteroscopic images. Novel robotic surgical techniques, such as buccal mucosa ureteroplasty, are changing the treatment algorithm for ureteral strictures.

Effect of COVID-19 on Graduating Urology Resident Case Logs: Analysis of the Accreditation Council of Graduate Medical Education National Data Reports.

OBJECTIVE: To assess the national case logs of the first graduating urologic resident cohorts to have trained during the COVID-19 pandemic for effects on surgical volumes. METHODS: The nationally aggregated Accreditation Council for Graduate Medical Education urology resident case logs were obtained for graduates of academic years (AYs) 2015-2016 through 2020-2021. Case volume differences for tracked index categories were compared between AYs with a 1-way analysis of variance. Data were then combined into pre-COVID and COVID-affected resident cohorts and differences in average cases logged were analyzed with 2-tailed student's t-tests. RESULTS: Graduating urology residents logged an average of 1322 (SD 24.8) cases over their residency during the examined period. Total cases had multiple statistical differences between AYs but the only index category with a statistically significant decrease for a COVID-affected AY compared to pre-COVID AY was pediatric majors: AY 2020-2021 logged fewer cases than AY 2015-2016 (53.9 vs 63.0, P = .004) and AY 2018-2019 (53.9 vs 61.2, P = .04). When aggregated into pre- and COVID-affected cohorts, both pediatric minor (123.4 vs 117.5, P = .049) and pediatric major (61.4 vs 56.8, P = .003) case averages decreased for the COVID-affected cohort of residents, but no adult index category decreased. CONCLUSION: National graduating urology resident surgical volume for adult index categories was maintained through the pandemic. Pediatric cases saw a statistical decrease in volume of questionable clinical significance. This does not eliminate concern that individuals may have experienced a detrimental impact on their resident education.

Incidentally found focal xanthogranulomatous pyelonephritis with extensive venous thrombus.

A 71-year-old woman with history of asthma presented with 2 months history of shortness of breath; on imaging an incidental left renal mass was noted. Subsequent renal protocol CT was obtained that showed a 4.5 cm left upper pole exophytic mass with renal vein thrombus extending into the inferior vena cava to the level of the caudate lobe concerning for renal cell carcinoma. She underwent an open left radical nephrectomy and IVC thrombectomy with subsequent postoperative pathology demonstrating xanthogranulomatous pyelonephritis without renal cell carcinoma.

Opioid-Limiting Pain Control After Transurethral Resection of the Prostate: A Randomized Controlled Trial.

OBJECTIVE: To assess whether a multimodal opioid-limiting protocol and patient education intervention can reduce postoperative opioid use following transurethral resection of the prostate. METHODS: This prospective, non-blinded, single-institution, randomized controlled trial (NCT04102566) assigned 50 patients undergoing a transurethral resection of the prostate to either a standard of care control (SOC) or multimodal experimental group (MMG). The intervention included adding ibuprofen to the postoperative pain regimen, promoting appropriate opioid use while hospitalized, an educational intervention, and discharging without opioid prescription. Data regarding demographics, operative data, opioid use, pain scores, and patient satisfaction were compared. RESULTS: A total of 47 patients were included, n = 23 (MMG) and n = 24 (SOC). Demographic and operative findings were similar. Statistical analysis for noninferiority demonstrated non-inferior inpatient pain control (mean pain score 2.5 MMG vs 2.4 SOC, P = 0.0003). The multimodal group used significantly fewer morphine milligram equivalents after discharge (0 vs 4.1, P = 0.04). Inpatient use was reduced but did not reach statistical significance (6.0 vs 9.8, P = 0.2). Mean satisfaction scores with pain control were similar (9.6 MMG vs 9.2 SOC, P = 0.32). No opioid prescriptions were requested after discharge. Adverse events and medication side effects were infrequent and largely similar between groups. CONCLUSION: Implementation of an opioid-limiting postoperative pain protocol and patient education resulted in no outpatient opioid use while maintaining patient satisfaction with pain control. Eliminating opioids following a common urologic procedure will decrease risk of opioid-related adverse events and have a positive downstream impact.

Factors associated with urinary incontinence in a community sample of young nulligravid women.

AIMS: The aim of this study is to identify factors associated with urinary incontinence (UI) in a community sample of young nulligravid women. METHODS: This was a secondary analysis from a cross-sectional survey-based study of cisgender women aged 18 to 25 years recruited through a national registry of research volunteers. Participants completed validated questionnaires assessing toileting behaviors, lower urinary tract symptoms (LUTS), and bowel symptoms. Women were excluded from analysis if currently pregnant, any prior pregnancy, cystectomy, or any neurologic disease including spinal cord injury, stroke, or multiple sclerosis. Analyses determined the prevalence of symptoms and evaluated candidate risk factors for UI. RESULTS: Final analyses included 964 women (mean age, 22.6 ± 2.0). Monthly UI was identified in 295 (30.6%) subjects, with mixed UI being the most common (56.9%; n = 168). Seventy-two women (7.4%) reported fecal incontinence (FI) and 24 (3.5%) women reported both UI and FI. After multivariable regression modeling, UI was associated with an intermittent urine stream and the delayed voiding toileting behavior subscale. CONCLUSIONS: UI in this cohort of young nulliparous women was highly prevalent and warrants further study as to the cause. Therapeutic guidelines to prevent UI and LUTS may need to be adjusted by targeting populations earlier than traditionally considered.

Women With Overactive Bladder Exhibit More Unhealthy Toileting Behaviors: A Cross-sectional Study.

OBJECTIVE: To determine whether women overactive bladder symptoms would report more frequent unhealthy toileting behaviors. METHODS: A community-based sample of adult women was electronically recruited to complete the Toileting Behavior Scale and the International Consultation on Incontinence Questionnaire - Overactive Bladder module, as well as clinical and demographic questionnaires. The associations between overactive bladder and toileting behavior subscales were assessed as continuous variables using Spearman's rank correlation and as dichotomous variables with multivariable logistic regression. RESULTS: Of the 6562 adult women included in the analytic sample, 1059 (16.1%) were classified as having overactive bladder. Of the toileting behavior subscales, convenience voiding had the highest, positive association with overactive bladder score (r = 0.301, P < .0001). On multivariable logistic regression, women with overactive bladder (OAB) were more likely to report behaviors of convenience voiding (odds ratio [OR] 1.13, confidence intervals [CI] 1.11-1.15), delayed voiding (OR 1.05, CI 1.02-1.08), straining to void (OR 1.05, CI 1.03-1.07), and position preference (OR 1.13, CI 1.08-1.18). CONCLUSION: OAB symptoms were associated with specific toileting behaviors of convenience voiding, delayed voiding, straining to void, and position preference. Further investigation is needed to determine if toileting behaviors are a risk factor for OAB or a compensatory adaptation to mitigate symptoms.

Toileting Behaviors of Women-What is Healthy?

PURPOSE: The objective of this study was to assess toileting behaviors in community dwelling women. MATERIALS AND METHODS: Women 18 years old or older were recruited through a national registry of research volunteers. They were asked to complete validated questionnaires assessing urinary symptoms and toileting behaviors, specifically place preference for voiding, convenience voiding, delayed voiding, straining during voiding and position preference for voiding. The PPBC (patient perception of bladder condition) was administered to assess the participant impression of bladder health. Analyses were done to determine the prevalence of each toileting behavior reported to occur sometimes or more often as well as differences in toileting behaviors in women with vs without self-perceived bladder problems based on the PPBC response. RESULTS: The 6,695 women who completed the questionnaires were 18 to 89 years old (mean ± SD age 41.4 ± 15). Of the women 79.9% identified as white and 71.0% were college educated. Of the women 6,613 (98.8%) reported a place preference for voiding. The 3,552 women (53.1%) who reported a bladder problem were more likely to report convenience voiding, delayed voiding and strained voiding behaviors. While 6,657 women (99.4%) reported sitting to void at home only 5,108 (76.2%) reported sitting when using public toilets. CONCLUSIONS: Certain toileting behaviors, of which some may be considered unhealthy, were common in this sample of women and most were associated with a perception of bladder problems. Voiding positions other than sitting were frequently used when away from home. These data have important implications for defining bladder health and implementing behavior based interventions for women with lower urinary tract symptoms.

Intelligent recognitive systems in nanomedicine.

There is a bright future in the development and utilization of nanoscale systems based on intelligent materials that can respond to external input providing a beneficial function. Specific functional groups can be incorporated into polymers to make them responsive to environmental stimuli such as pH, temperature, or varying concentrations of biomolecules. The fusion of such "intelligent" biomaterials with nanotechnology has led to the development of powerful therapeutic and diagnostic platforms. For example, targeted release of proteins and chemotherapeutic drugs has been achieved using pH-responsive nanocarriers while biosensors with ultra-trace detection limits are being made using nanoscale, molecularly imprinted polymers. The efficacy of therapeutics and the sensitivity of diagnostic platforms will continue to progress as unique combinations of responsive polymers and nanomaterials emerge.

Therapeutic applications of hydrogels in oral drug delivery.

INTRODUCTION: Oral delivery of therapeutics, particularly protein-based pharmaceutics, is of great interest for safe and controlled drug delivery for patients. Hydrogels offer excellent potential as oral therapeutic systems due to inherent biocompatibility, diversity of both natural and synthetic material options and tunable properties. In particular, stimuli-responsive hydrogels exploit physiological changes along the intestinal tract to achieve site-specific, controlled release of protein, peptide and chemotherapeutic molecules for both local and systemic treatment applications. AREAS COVERED: This review provides a wide perspective on the therapeutic use of hydrogels in oral delivery systems. General features and advantages of hydrogels are addressed, with more considerable focus on stimuli-responsive systems that respond to pH or enzymatic changes in the gastrointestinal environment to achieve controlled drug release. Specific examples of therapeutics are given. Last, in vitro and in vivo methods to evaluate hydrogel performance are discussed. EXPERT OPINION: Hydrogels are excellent candidates for oral drug delivery, due to the number of adaptable parameters that enable controlled delivery of diverse therapeutic molecules. However, further work is required to more accurately simulate physiological conditions and enhance performance, which is important to achieve improved bioavailability and increase commercial interest.
