Antibiotic Use in Hospital Urinary Tract Infections After FDA Regulation.

BACKGROUND: The FDA issued a "black box" warning regarding risks of fluoroquinolones in 2008 with updates in 2011, 2013, and 2016. OBJECTIVE: To examine antimicrobial use in hospital-treated UTIs from 2000 to 2020. DESIGN: Cross-sectional study with interrupted time series analysis. PARTICIPANTS: Patient encounters with a diagnosis of UTI from January 2000 to March 2020, excluding diagnoses of renal abscess, chronic cystitis, and infection of the gastrointestinal tract, lungs, or prostate. MAIN MEASURES: Monthly use of fluoroquinolone and non-fluoroquinolone antibiotics were assessed. Fluoroquinolone resistance was assessed in available cultures. Interrupted time series analysis examined level and trend changes of antimicrobial use with each FDA label change. KEY RESULTS: A total of 9,950,790 patient encounters were included. From July 2008 to March 2020, fluoroquinolone use declined from 61.7% to 11.7%, with similar negative trends observed in inpatients and outpatients, age ≥ 60 and < 60 years, males and females, patients with and without pyelonephritis, and across physician specialties. Ceftriaxone use increased from 26.4% encounters in July 2008 to 63.6% of encounters in March 2020. Among encounters with available culture data, fluoroquinolone resistance declined by 28.9% from 2009 to 2020. On interrupted time series analysis, the July 2008 FDA warning was associated with a trend change (-0.32%, < 0.001) and level change (-5.02%, p < 0.001) in monthly fluoroquinolone use. CONCLUSIONS: During this era of "black box" warnings, there was a decline in fluoroquinolone use for hospital-treated UTI with a concomitant decline in fluoroquinolone resistance and rise in ceftriaxone use. Efforts to restrict use of a medication class may lead to compensatory increases in use of a single alternative agent with changes in antimicrobial resistance profiles.

Prostate cancer genetic alterations in Hispanic men.

BACKGROUND: Differences in DNA alterations in prostate cancer among White, Black, and Asian men have been widely described. This is the first description of the frequency of DNA alterations in primary and metastatic prostate cancer samples of self-reported Hispanic men. METHODS: We utilized targeted next-generation sequencing tumor genomic profiles from prostate cancer tissues that underwent clinical sequencing at academic centers (GENIE 11th). We decided to restrict our analysis to the samples from Memorial Sloan Kettering Cancer Center as it was by far the main contributor of Hispanic samples. The numbers of men by self-reported ethnicity and racial categories were analyzed via Fisher's exact test between Hispanic-White versus non-Hispanic White. RESULTS AND LIMITATIONS: Our cohort consisted of 1412 primary and 818 metastatic adenocarcinomas. In primary adenocarcinomas, TMPRSS2 and ERG gene alterations were less common in non-Hispanic White men than Hispanic White (31.86% vs. 51.28%, p = 0.0007, odds ratio [OR] = 0.44 [0.27-0.72] and 25.34% vs. 42.31%, p = 0.002, OR = 0.46 [0.28-0.76]). In metastatic tumors, KRAS and CCNE1 alterations were less prevalent in non-Hispanic White men (1.03% vs. 7.50%, p = 0.014, OR = 0.13 [0.03, 0.78] and 1.29% vs. 10.00%, p = 0.003, OR = 0.12 [0.03, 0.54]). No significant differences were found in actionable alterations and androgen receptor mutations between the groups. Due to the lack of clinical characteristics and genetic ancestry in this dataset, correlation with these could not be explored. CONCLUSION: DNA alteration frequencies in primary and metastatic prostate cancer tumors differ among Hispanic-White and non-Hispanic White men. Notably, we found no significant differences in the prevalence of actionable genetic alterations between the groups, suggesting that a significant number of Hispanic men could benefit from the development of targeted therapies.

Variability of Prostate MRI Charges Among U.S. Hospital-Based Facilities.

The Premier Healthcare Database was used to assess charge variation for prostate MRI examinations in U.S. hospitals from January 2010 to March 2020. In 552 facilities performing 37,073 examinations, the median charge per examination was $4419 with 26-fold variation between the lowest ($593) and highest ($15,150) median facility charges. In multilevel linear regression analysis, interfacility variation explained 63.9% of charge variation. Patients may be charged vastly different prices for prostate MRI depending on the facility.

Incidence of Kidney Stones in the United States: The Continuous National Health and Nutrition Examination Survey.

PURPOSE: The incidence of kidney stones in the United States is currently unknown. Here, we assessed the incidence of kidney stones using recent, nationally representative data. MATERIALS AND METHODS: We used the National Health and Nutrition Examination Survey (NHANES) from 2015 to 2018. During this time participants were asked, "Have you ever had a kidney stone?" and "In the past 12 months, have you passed a kidney stone?" Demographics analyzed include age, race, gender, body mass index, history of smoking, diabetes, hypertension, hypercholesterolemia and gout. Multivariable models were used to assess the independent impact of subject characteristics on kidney stone prevalence and incidence. RESULTS: Data were available on 10,521 participants older than age 20. The prevalence of kidney stones was 11.0% (95% CI 10.1-12.0). The 12-month incidence of kidney stones was 2.1% (95% CI 1.5-2.7), or 2,054 stones per 100,000 adults. We identified significant relationships between stone incidence and subject age, body mass index, race and history of hypertension. CONCLUSIONS: Here we find a substantially higher 12-month incidence of kidney stones than previous reports. We also validate known risk factors for stone prevalence as associated with incidence. The remarkable incidence and prevalence of stones is concerning and has implications for disease prevention and allocation of medical resources.

Impact of Left-Digit Age Bias in the Treatment of Localized Prostate Cancer.

PURPOSE: Left-digit bias is a phenomenon in which the leftmost digit of a number disproportionately influences decision making. We measured the effect of left-digit age bias on treatment recommendations for localized prostate cancer. MATERIALS AND METHODS: We included men with clinically localized prostate adenocarcinoma in Surveillance, Epidemiology, and End Results from 2004 to 2018 and the National Cancer Database from 2004 to 2016. Primary outcomes were recommendations for radiation therapy and radical prostatectomy. Regression discontinuity was used to assess whether age increase from 69 to 70 years was associated with disproportionate changes in treatment recommendations. RESULTS: In Surveillance, Epidemiology, and End Results, discontinuities were found in the proportion of patients recommended for radiation among the entire cohort (effect size 2.2%, P < .01) and among patients with Gleason 6 (1.6%, P < .01), Gleason 7 (2.5%, P < .01), and Gleason ≥8 (2.1%, P < .01) cancer, while the proportion recommended for prostatectomy decreased in the entire cohort (-1.4%, P < .01) and in patients with Gleason 7 cancer (-2.4%, P < .01). In the National Cancer Database, discontinuity from age 69 to 70 was found in recommendations for radiation in the entire cohort (effect size: 3.1%, P < .01) and in patients with Gleason 6 (2.2%, P < .01), Gleason 7 (4.0%, P < .01), and Gleason ≥8 (2.3%, P < .02) cancer, while the proportion recommended for prostatectomy decreased at this cutoff in the entire cohort (effect size: -2.7%, P < .01) and patients with Gleason 6 (-2.2%, P < .01) and Gleason 7 (-3.7%, P < .01) cancer. CONCLUSIONS: In patients with localized prostate cancer, left-digit age change from 69 to 70 was associated with disproportionately increased recommendations for radiation and decreased recommendations for prostatectomy.

Developments in optimizing transperineal prostate biopsy.

PURPOSE OF REVIEW: Prostate biopsy is a very commonly performed office procedure leading to the diagnosis of the most prevalent solid-organ malignancy in American men. Although the transrectal technique for prostate biopsy remains the gold standard, there is increasing interest in the transperineal approach as it offers a clean, percutaneous approach that significantly decreases the risk for infection. In this review, we discuss emerging developments in transperineal prostate biopsy that may optimize the way biopsies are performed in clinical practice. RECENT FINDINGS: Similarly, to transrectal biopsy, the transperineal approach also allows for the performance of systematic and MRI-targeted biopsy cores. As transperineal biopsy obviates the translocation of rectal bacteria to the prostate or bloodstream, in contrast to transrectal biopsy, it is feasible to forgo peri-procedural antibiotics in accordance with professional guidelines. This may attenuate antimicrobial resistance that may be associated with augmented prophylaxis. In addition, although transperineal biopsy may be traditionally performed under general anesthesia using a template grid, it may also be performed freehand under local anesthesia or sedation. Avoiding prophylactic antibiotics and general anesthesia as well as reducing infections/hospitalizations for transperineal biopsy scaled nationally will likely result in significant healthcare savings. SUMMARY: Transperineal biopsy with combined systematic and MRI-targeted cores, offers several advantages over conventional transrectal biopsy. Transperineal biopsy under local anesthesia and without periprocedural antibiotic is emerging as a promising method for prostate cancer diagnosis and surveillance.

Face morphogenesis is promoted by Pbx-dependent EMT via regulation of Snail1 during frontonasal prominence fusion.

Human cleft lip with or without cleft palate (CL/P) is a common craniofacial abnormality caused by impaired fusion of the facial prominences. We have previously reported that, in the mouse embryo, epithelial apoptosis mediates fusion at the seam where the prominences coalesce. Here, we show that apoptosis alone is not sufficient to remove the epithelial layers. We observed morphological changes in the seam epithelia, intermingling of cells of epithelial descent into the mesenchyme and molecular signatures of epithelial-mesenchymal transition (EMT). Utilizing mouse lines with cephalic epithelium-specific Pbx loss exhibiting CL/P, we demonstrate that these cellular behaviors are Pbx dependent, as is the transcriptional regulation of the EMT driver Snail1. Furthermore, in the embryo, the majority of epithelial cells expressing high levels of Snail1 do not undergo apoptosis. Pbx1 loss- and gain-of-function in a tractable epithelial culture system revealed that Pbx1 is both necessary and sufficient for EMT induction. This study establishes that Pbx-dependent EMT programs mediate murine upper lip/primary palate morphogenesis and fusion via regulation of Snail1. Of note, the EMT signatures observed in the embryo are mirrored in the epithelial culture system.

Practice patterns of vasal reconstruction in a large United States cohort.

We aimed to characterise diverse practice patterns for vasal reconstruction and to determine whether surgeon volume is associated with vasoepididymostomy performance at the time of reconstruction. We identified adult men who underwent vasal reconstruction from 2000 to 2020 in Premier Healthcare Database and determined patient, surgeon, cost and hospital characteristics for each procedure. We identified 3,494 men who underwent either vasovasostomy-alone (N = 2,595, 74.3%) or any-vasoepididymostomy (N = 899, 25.7%). The majority of providers (N = 487, 88.1%) performed only-vasovasostomy, 10 (1.8%) providers performed only-vasoepididymostomy and 56 (10.1%) providers performed both. Median total hospital charge of vasoepididymostomy was significantly higher than vasovasostomy ($39,163, interquartile range [IQR]$11,854-53,614 and $17,201, IQR$10,904-29,986, respectively). On multivariable regression, men who underwent procedures at nonacademic centres (OR 2.71, 95% CI 2.12-3.49) with higher volume surgeons (OR 11.60, 95% CI 8.65-16.00) were more likely to undergo vasoepididymostomy. Furthermore, men who underwent vasoepididymostomy were more likely to self-pay (OR 2.35, 95% CI 1.83-3.04, p < .001) and more likely had procedures in the Midwest or West region (OR 2.22, 95% CI 1.66-2.96 and OR 2.11, 95% CI 1.61-2.76, respectively; p < .001). High-volume providers have increased odds of performing vasoepididymostomy at the time of reconstruction but at a significantly higher cost. These data suggest possibly centralising reconstructive procedures among high-volume providers.

Urinary pH and the risk of recurrence in patients with non-muscle invasive bladder cancer.

INTRODUCTION: To evaluate the effect of urine pH on tumor recurrence rates in patients undergoing surveillance after initial diagnosis of non-muscle invasive bladder cancer (NMIBC). MATERIALS AND METHODS: All patients diagnosed with NMIBC at a tertiary referral center from January 2004 to March 2015 were reviewed. Our primary outcome was time to first recurrence after transurethral resection of bladder tumor (TURBT). Patients were analyzed according to the average urine pH of all urinalysis data over the surveillance period from TURBT to first recurrence. Kaplan-Meier survival analysis was used to determine differences in median time to recurrence. Cox proportional hazards regression was used to assess independent predictors of cancer recurrence. RESULTS: A total of 252 patients were included, of which 155 patients had average pH ≤ 6 (median pH 5.5) and 97 patients had average pH > 6 (median pH 6.8), p < 0.001. There was no significant difference in median time to recurrence between low/acidic pH (≤ 6) and high/basic pH (> 6) groups (28 months versus 17 months, respectively, p = 0.3444). Similarly, urine pH did not affect the risk of recurrence in a subgroup analysis stratified by smoking status. On multivariable Cox regression analysis, there was no association between average pH and recurrence among high grade tumors (HR = 1.33, 95% CI = 0.76 to 2.34, p = 0.3186), or low grade tumors (HR = 1.013, 95% CI = 1.01 to 1.58, p = 0.96). CONCLUSIONS: There was no association between urine pH and risk of tumor recurrence, regardless of smoking status. These findings suggest that modification of urine pH is unlikely to decrease the frequency of tumor recurrence in patients with NMIBC.

Prognostic Significance of a Negative Prostate Biopsy: An Analysis of Subjects Enrolled in a Prostate Cancer Screening Trial.

PURPOSE: To our knowledge the optimal treatment of patients following a negative prostate biopsy is unknown. Consequently, resources are increasingly being directed toward risk stratification in this cohort. However, the risk of prostate cancer mortality in this group before the introduction of supplemental biomarkers and imaging techniques is unclear. MATERIALS AND METHODS: The PLCO (Prostate, Lung, Colorectal and Ovarian Cancer) Screening Trial provides survival data prior to the implementation of new diagnostic interventions. We divided men with an initial positive screen and a subsequent prostate biopsy into cohorts based on positive or negative results. Prostate cancer specific mortality was then compared to that in the trial control arm to estimate the prognostic significance of biopsy results relative to the general population. RESULTS: A total of 36,525 and 36,560 patients comprised the screening and control arms, respectively. Of 4,064 subjects with a positive first screen 1,233 underwent a linked biopsy, of which 473 were positive and 760 were negative. At a median followup of 12.9 years, 1.1% of men in the negative biopsy cohort had died of prostate cancer. The difference in mortality rates between the negative biopsy and control arms was 0.734 deaths per 1,000 person-years. The proportional subhazard ratios of prostate cancer specific mortality for negative biopsy and positive biopsy relative to the control arm were 2.93 (95% CI 1.44-5.99) and 18.77 (95% CI 12.62-27.93), respectively. CONCLUSIONS: After a negative prostate biopsy, men face a relatively low risk of death from prostate cancer when followed with traditional markers and biopsy techniques. This suggests limited potential for new diagnostic interventions to improve survival in this group.

Robot-assisted partial cystectomy: perioperative outcomes and early oncological efficacy.

OBJECTIVE: To report on patients undergoing robot-assisted partial cystectomy (RAPC), focusing on perioperative outcomes over a range of clinical, anatomical and pathological variables, as well as the overall oncological efficacy of this approach. PATIENTS AND METHODS: We retrospectively reviewed all patients who underwent RAPC by a single surgeon between 2005 and 2015. We identified 29 patients who underwent surgery for definitive management of a primary bladder tumour. Clinicopathological data and perioperative variables were recorded. Continuous variables were compared using the Student's t-test. Prediction of perioperative outcomes for those undergoing RAPC for intra-diverticular neoplasms was done using univariate logistic regression. Survival was estimated using the Kaplan-Meier method. RESULTS: The median (interquartile range) patient age was 75 (65-81) years, 18 patients (62.1%) had an American Society of Anesthesiologists classification of ≥3, and 10 patients (34.5%) had a history of prior abdominal surgery. The median estimated blood loss (EBL) was 50 mL and the median length of stay (LOS) was 1 day. Two patients (6.9%) had a perioperative complication and five (17.9%) a post-discharge complication at ≤90 days, all of which were minor. The positive surgical margin rate was 3.6% and in those with muscle-invasive disease a median of 12 lymph nodes were removed. Neither the size of diverticulum nor the need for ureteric re-implantation was predictive of LOS, EBL, or complication (P > 0.05). We did not encounter any wound, port site, or unusual recurrence patterns to suggest the technical factors of a robotic approach influenced oncological outcomes. The 5-year overall and recurrence-free survival rates were 79% and 68%, respectively. CONCLUSION: RAPC confers the ability to achieve favourable outcomes with low morbidity and reduced hospital stays. Oncological efficacy compares favourably with the published literature. For experienced surgeons, this may represent the optimal surgical approach for organ-preserving bladder surgery.

Prostate size, nocturia and the digital rectal examination: a cohort study of 30 500 men.

OBJECTIVES: To evaluate the utility of the digital rectal examination (DRE) in estimating prostate size and the association of DRE with nocturia in a population-based cohort. SUBJECTS AND METHODS: We identified all men randomized to the screening arm of the Prostate, Lung, Colorectal, and Ovarian Cancer Screening (PLCO) trial for whom DRE results were available. Men were excluded if they had a history of prostate surgery or incident prostate cancer. Prostate posterior surface area was derived from DRE sagittal and transverse estimates. Relationships between prostate posterior surface area, transrectal ultrasonography (TRUS), prostate-specific antigen (PSA) and nocturia were analysed using intraclass correlation coefficients (ICCs), Spearman's rank correlation and multivariable logistic regression. RESULTS: A total of 30 500 men met the inclusion criteria, with 103 275 screening visits containing paired DRE and PSA data. Digital rectal examination posterior surface area estimates had an ICC of 0.547 (95% CI 0.541-0.554) and were significantly yet modestly correlated with elevated PSA level (rs = 0.18, P < 0.001) and TRUS prostate volume (rs = 0.32, P < 0.001). Prostate posterior surface area was significantly associated with nocturia on multivariable analysis, but was not significant in stratified analysis of men with cardiovascular risk factors (hypertension, diabetes, high body mass index, stroke). In men without these risk factors, the highest quintile of DRE posterior surface area had 22% greater odds of nocturia than the lowest quintile (odds ratio 1.216, 95% CI 1.036-1.427). CONCLUSIONS: Digital rectal examination is a modestly accurate tool for measuring prostate volume. While DRE posterior surface area represents a statistically significant predictor of nocturia, the magnitude of effect suggests it has limited clinical utility for assessing this condition, particularly in the presence of cardiovascular risk factors.

The impact of socioeconomic status on perioperative complications and oncologic outcomes in patients undergoing radical cystectomy.

PURPOSE: To examine if patients of lower socioeconomic status (SES) are at higher risk of perioperative complications and experience different oncologic outcomes after radical cystectomy (RC). METHODS: Retrospective review was performed on 383 consecutive non-metastatic patients who underwent definitive RC at a tertiary referral center. Along with clinical and pathologic parameters traditionally utilized for risk stratification, potential social determinants of health were estimated using US Census data. Zip code-derived proxies of SES included median annual household income and percentage of residents completing high school education. Patients were grouped based on SES parameters, and potential differences were assessed. Multivariable logistic regression was then performed to identify predictors of complication within 90 days of RC. Survival outcomes were plotted using Kaplan-Meier survival curves. RESULTS: Overall, 167 (46.2%) patients suffered any complication within 90 days of RC. On multivariable analysis, length of stay (p ≤ 0.001), lower income grouping (p = 0.03), and lowest education tertile (p = 0.007) were significant predictors of any complication. Income (p = 0.04) and education (p = 0.008) groupings remained significant predictors in a subset analysis looking specifically at post-discharge complications. No significant differences in recurrence-free or overall survival estimates were observed among education (log-rank test: p > 0.9 and p = 0.6, respectively) or income (log-rank test: p = 0.2 and p = 0.09, respectively) groupings. CONCLUSION: Patients of lower socioeconomic status who undergo RC for bladder cancer are at increased risk of perioperative complications. Further studies are needed to clarify this relationship, and to explore interventions aimed to improve outcomes.

Factors Impacting the Occurrence of Local, Distant and Atypical Recurrences after Robot-Assisted Radical Cystectomy: A Detailed Analysis of 310 Patients.

PURPOSE: Peritoneal carcinomatosis and extrapelvic lymph node metastases can be seen following robot-assisted radical cystectomy. In an attempt to identify predictors of these atypical metastases we report a detailed analysis of patients treated with robot-assisted radical cystectomy in whom recurrences developed. MATERIALS AND METHODS: A total of 310 patients underwent robot-assisted radical cystectomy for bladder cancer from 2001 to 2015. Descriptive statistics were used to compare baseline variables between patients without recurrence and those with local, distant or atypical recurrence. Univariate and multivariable regression models were used to assess the effect of variables on oncologic outcomes including recurrence location. RESULTS: At a median followup of 24 months (IQR 14-51) 81 patients had recurrence. On multivariable analysis tumor classification, lymphovascular invasion, estimated glomerular filtration rate less than 60 ml/minute/1.73 m2 and perioperative blood transfusion were significantly associated with any recurrence. Specific analyses showed that tumor and nodal classification, lymphovascular invasion and positive surgical margins were associated with all 3 recurrence locations (all p <0.05). Previous abdominal surgery was protective against atypical recurrences (HR 0.36, 95% CI 0.13-0.95, p = 0.04). Estimated glomerular filtration rate less than 60 ml/minute/1.73 m2 and perioperative blood transfusion conferred a higher risk of distant or atypical recurrence but not of local recurrence (all p <0.05). Operative time and previous pelvic radiotherapy were not associated with any recurrence locations. CONCLUSIONS: Predictors of distant recurrences, peritoneal carcinomatosis and extrapelvic lymph node metastases after robot-assisted radical cystectomy did not significantly differ and were mainly dictated by pathological tumor characteristics. Results suggest that the risk of atypical recurrence is chiefly influenced by tumor biology rather than surgical aspects.

Trends in hospital price transparency after implementation of the CMS Final Rule.

OBJECTIVE: To assess trends in hospital price disclosures after the Centers for Medicare & Medicaid Services (CMS) Final Rule went into effect. DATA SOURCES AND STUDY SETTING: The Turquoise Health Price Transparency Dataset was used to identify all US hospitals that publicly displayed pricing from 2021 to 2023. STUDY DESIGN: Price-disclosing versus nondisclosing hospitals were compared using Pearson's Chi-squared and Wilcoxon rank sum tests. Bayesian structural time-series modeling was used to determine if enforcement of increased penalties for nondisclosure was associated with a change in the trend of hospital disclosures. DATA COLLECTION/EXTRACTION METHODS: Not applicable. PRINCIPAL FINDINGS: As of January 2023, 5162 of 6692 (77.1%) US hospitals disclosed pricing of their services, with the majority (2794 of 5162 [54.1%]) reporting their pricing within the first 6 months of the final rule going into effect in January 2021. An increase in hospital disclosures was observed after penalties for nondisclosure were enforced in January 2022 (relative effect size 20%, p = 0.002). Compared with nondisclosing hospitals, disclosing hospitals had higher annual revenue, bed number, and were more likely to be have nonprofit ownership, academic affiliation, provide emergency services, and be in highly concentrated markets (p < 0.001). CONCLUSIONS: Hospital pricing disclosures are continuously in flux and influenced by regulatory and market factors.

High variability in self-pay pricing for vasectomy and vasectomy reversal in the United States.

CONTEXT: In the United States (US) men who undergo vasectomy and/or vasectomy reversal (vasovasotomy) are likely to pay out-of-pocket for these procedures. We characterized the publicly disclosed pricing of both procedures with a focus on variability in self-pay prices. METHODS: We queried all US hospitals for publicly disclosed prices of vasectomy and vasovasotomy. We assessed interhospital variability in self-pay pricing and compared hospitals charging high (≥75th percentile) and low (≤25th percentile) self-pay prices for either procedure. We also examined trends in pricing after the 2022 US Supreme Court decision that allowed individual states to ban abortion. RESULTS: Of 6692 hospitals, 1375 (20.5%) and 281 (4.2%) disclosed self-pay prices for vasectomy and vasovasotomy, respectively. There was a 17-fold difference between the 10th and 90th percentile self-pay prices for vasectomy ($421-$7147) and a 39-fold difference for vasovasotomy ($446-$17,249). Compared with hospitals charging low (≤25th percentile) self-pay prices for vasectomy or vasovasotomy, hospitals charging high (≥75th percentile) prices were larger (median 150 vs. 59 beds, p < 0.001) and more likely to be for-profit (31.2% vs. 7.8%, p < 0.001), academic-affiliated (52.7% vs. 23.1%, p < 0.001), and located in an urban zip code (70.1% vs. 41.3%, p < 0.001). From October 2022 to April 2023, the median self-pay price of vasectomy increased by 10% (from $1667 to $1832) while the median self-pay price of vasovasotomy decreased by 16% (from $3309 to $2786). CONCLUSION: We found large variability in self-pay pricing for vasectomy and vasectomy reversal, which may serve as a barrier to the accessibility of male reproductive care.

Real-world practice in Peyronie's disease management: Results from a national survey of urologists.

BACKGROUND: Despite many available treatments for Peyronie's disease (PD), practice patterns of available therapeutics are not well characterized. OBJECTIVE: We conducted a national survey of urologists to characterize real-world practice patterns of PD management and to characterize the use of therapies discouraged by the American Urological Association guidelines on PD management. MATERIALS AND METHODS: A 34-item survey was distributed via RedCap to urologists who treat patients with PD in all American Urological Association sections. Questions elicited demographic information as well as practices in the diagnosis and treatment of PD. Comparisons were made with Pearson's chi-squared test. The primary outcome was reported use of therapies discouraged by the American Urological Association guidelines on PD. RESULTS: A total of 145 respondents completed the survey, of whom 19% were fellowship trained in andrology/sexual medicine, 36% practiced in an academic setting, and 50% had at least 20 years in practice. Only 60% of respondents reporting performing in-office curvature assessment prior to commencing intralesional injection or surgical treatment, with higher prevalence in andrology/sexual medicine fellowship-trained versus non-fellowship-trained urologists (85% vs. 54%, p = 0.003). The most popular treatment modalities were collagenase clostridium histolyticum (61% of respondents), phosphodiesterase-5 inhibitors (54%), and penile traction (53%). Twenty-one percent of respondents reported currently using a treatment that is explicitly discouraged by the American Urological Association guidelines (extracorporeal shockwave therapy for curvature, L-carnitine, omega-3 fatty acids, or vitamin E). DISCUSSION: Patients seeking PD treatment may be offered different therapies, some of which are not evidence-based, depending on the treating urologist. This study is limited by self-selection and response bias. Its strength is that it represents a cross-sectional overview of real-world practice patterns in PD management, which has not been previously described. CONCLUSIONS: A significant proportion of urologists reported PD management practices that are not evidence-based and not guideline-supported.
