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.

National Adherence to Guidelines for Antimicrobial Prophylaxis for Patients Undergoing Radical Cystectomy.

PURPOSE: The sentinel reference for antibiotic prophylaxis for radical cystectomy with ileal conduit in the AUA Guidelines reports data from 2003-2013 and has not been updated in the interim. Here, we assess adherence to antibiotic prophylaxis guidelines among patients undergoing radical cystectomy with ileal conduit for bladder cancer using a large national database. As a secondary objective, we assess the association between antimicrobial use and postoperative infection during the index admission following cystectomy. MATERIALS AND METHODS: The Premier Healthcare Database was queried for all patients undergoing cystectomy with ileal conduit with diagnosis of bladder cancer between 2015 and 2020. Antibiotics used and the duration of use was determined by charge codes and grouped as guidelines-based or not according to 2019 AUA Guidelines. Association with infectious complications was assessed by logistic mixed effects regression models. RESULTS: Among 6,708 patients undergoing cystectomy with ileal conduit, only 28% (1,843/6,708) were given prophylaxis according to AUA guidelines; 1.8% (121/6,708) of patients received an antifungal and 37% (2,482/6,708) received extended duration prophylaxis beyond postoperative day 1. Patients who received guidelines-based prophylaxis were less likely to be diagnosed with a urinary tract infection (21% vs 24%, P = .04), pyelonephritis (5.1% vs 7.7%, P < .001), bacterial infection (24% vs 27%, P = .03), or pneumonia (12% vs 17%, P < .001). There was no statistically significant difference in clostridium difficile infection between guidelines-based and nonguidelines-based prophylaxis (3.2% vs 3.7%, P = .32). In a multivariable logistic regression adjusting for age, race, insurance, and hospital and provider characteristics, nonguideline antibiotic prophylaxis (OR 1.27 [1.12, 1.43], P < .001) was associated with an increased odds of infectious events, whereas a robotic approach (OR 0.82 [0.73, 0.92], P < .001) was associated with lower odds. CONCLUSIONS: Seventy-three percent of patients fail to receive guideline-based antibiotic prophylaxis when undergoing radical cystectomy with conduit, which was largely driven by extended duration antibiotic use. Despite the shorter duration of antibiotics, we found that guideline-based prophylaxis was associated with a 25% decrease in the odds of infectious complications. While residual confounding is possible, these data support current AUA guidelines and suggest a need for outreach to improve guideline adherence.

Modern surgical treatment of azoospermia.

PURPOSE OF REVIEW: To review noteworthy research from the last 2 years on surgical management of azoospermia. RECENT FINDINGS: The recommended treatments for nonobstructive and obstructive azoospermia have not appreciably changed. However, recent level-1 evidence has reinforced superiority of micro-dissection testicular sperm extraction over sperm aspiration in men with nonobstructive azoospermia, and several studies have identified genetic and other clinical factors that may aid in selecting candidates for testicular sperm extraction. Machine learning technology has shown promise as a decision support system for patient selection prior to sperm retrieval as well a tool to aid in sperm identification from testis tissue. SUMMARY: Most men with obstructive azoospermia who desire fertility can be offered either surgical reconstruction or sperm retrieval. For men with nonobstructive azoospermia, sperm retrieval with microdissection testicular sperm extraction remains the gold standard treatment. Uncovering more genetic causes of nonobstructive azoospermia may aid in properly counseling and selecting patients for microdissection testicular sperm extraction. Neural networks and deep learning may have a future role in patient selection for surgical sperm retrieval and postprocedural sperm identification.

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.

Trends over 20 years of antimicrobial prophylaxis for artificial urinary sphincter surgery.

INTRODUCTION AND OBJECTIVE: Perioperative antimicrobial prophylaxis is crucial for prevention of prosthesis and patient morbidity after artificial urinary sphincter (AUS) placement. While antibiotic guidelines exist for many urologic procedures, adoption patterns for AUS surgery are unclear. We aimed to assess trends in antibiotic prophylaxis for AUS and outcomes relative to American Urological Association (AUA) Best Practice guidelines. METHODS: The Premier Healthcare Database was queried from 2000 to 2020. Encounters involving AUS insertion, revision/removal, and associated complications were identified via ICD and CPT codes. Premier charge codes were used to identify antibiotics used during the insertion encounter. AUS-related complication events were found using patient hospital identifiers. Univariable analysis between hospital/patient characteristics and use of guideline-adherent antibiotics was done via chi-squared and Kruskal-Wallis tests. A multivariable logistic mixed effects model was used to assess factors related to the odds of complication, specifically the use of guideline-adherent versus nonadherent regimens. RESULTS: Of 9775 patients with primary AUS surgery, 4310 (44.1%) received guideline-adherent antibiotics. The odds of guideline-adherent regimen use increased 7.7% per year with 53.0% (830/1565) receiving guideline-adherent antibiotics by the end of the study period. Patients with guideline-adherent regimens had a decreased risk of any complication (odds ratio [OR]: 0.83, 95% confidence interval [CI]: 0.74-0.93) and surgical revision (OR: 0.85, 95% CI: 0.74-0.96) within 3 months; however, no significant difference in infection within was noted (OR: 0.89, 95% CI: 0.68-1.17) within 3 months. CONCLUSIONS: Adherence to AUA antimicrobial guidelines for AUS surgery appears to have increased over the last two decades. While guideline-adherent regimens were associated with decreased risk of any complication and surgical intervention, no significant association was found with risk of infection. Surgeons appear to be increasingly following AUA recommendations for antimicrobial prophylaxis for AUS surgery, however, further level 1 evidence should be obtained to demonstrate conclusive benefit of these regimens.

Effects of Chemo- and Radiation Therapy on Microsurgical Testicular Sperm Extraction for Men with Nonobstructive Azoospermia.

PURPOSE: Men who survive cancer as children or young adults may have severe spermatogenic impairment with azoospermia requiring surgical sperm retrieval and assisted reproductive technologies. We assessed treatment outcomes from a large series of cancer patients with prior radiation and/or chemotherapy. MATERIALS AND METHODS: Men with nonobstructive azoospermia who underwent initial microsurgical testicular sperm extraction from 1995-2020 from a high-volume surgeon at a single institution were identified. Those with a history of malignancy treated by radiation therapy and/or chemotherapy were included. The primary outcome was successful sperm retrieval. RESULTS: A total of 106 men were evaluated, of whom 57 received chemotherapy and radiation, 44 received only chemotherapy and 5 received only radiation. Sperm retrieval was successful in 39 of 106 (37%) men, with higher likelihood of retrieval in men who received only chemotherapy compared to men who received chemotherapy and radiation (61% vs 18%, p <0.001). None of the 18 patients who received chemotherapy with radiation to the pelvis had successful sperm retrieval, compared to 26% of patients who received chemotherapy with extra-pelvic radiation (p=0.02). CONCLUSIONS: Chemotherapy and radiation for cancer may result in nonobstructive azoospermia that can be treated to allow fertility. However, pelvic radiation therapy is associated with the worst prognosis for successful treatment with microsurgical sperm retrieval and in vitro fertilization; we observed no cases of successful retrieval in men who received pelvic radiation therapy. These data are useful for pretreatment counseling, suggesting that men with prior radiation therapy may not be candidates for surgical sperm retrieval.

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.

Findings from an international survey of urology trainee experience with prostate biopsy.

OBJECTIVE: To assess urology trainees' exposure to transperineal prostate biopsy (TP-Bx) and intent to use TP-Bx in practice. SUBJECTS AND METHODS: A 34-question survey about prostate biopsy was distributed to urology trainees in the United States and Europe. Primary outcomes were exposure to TP-Bx in training and intent to use TP-Bx post training. Exposure to transrectal prostate biopsy (TR-Bx) and magnetic resonance imaging-targeted biopsy (MRI-Bx) was also assessed. Survey answers were compared between groups as categorical variables using Fisher's exact test. Multivariable logistic regression was used to identify factors associated with intent of performing TP-Bx post training. RESULTS: A total of 658 trainees from 19 countries completed the survey. Of these, 313 trainees (48%) reported exposure to TP-Bx, 370 (56%) reported exposure to MRI-Bx, and 572 (87%) reported exposure to TR-Bx. There was significant heterogeneity in TP-Bx exposure among countries (P < 0.001), with the highest prevalence in Italy (72%) and the lowest prevalence in Greece (4%). Intent to perform TP-Bx post training was higher in those exposed to TP-Bx during training (89% vs 58%; P < 0.001) and did not differ between trainees in postgraduate year (PGY) 1-3 vs those in PGY ≥4 (73% vs 72%; P = 0.7). On multivariable regression, exposure to TP-Bx in training was independently associated with increased intent to perform TP-Bx post training (odds ratio 5.09, 95% confidence interval 3.29-8.03; P < 0.001). CONCLUSIONS: Fewer than half of 658 surveyed urology trainees reported exposure to TP-Bx, with significant heterogeneity among countries. Greater experience with TP-Bx in training was associated with greater intent to perform TP-Bx post training. A minimum requirement of TP-Bx cases during urological training may increase resident familiarity and adoption of this guideline-endorsed prostate biopsy approach.

Real-world comparative effectiveness of shockwave lithotripsy versus ureterorenoscopy for the treatment of urinary stones.

PURPOSE: To identify clinical and non-clinical predictors of treatment failure and perioperative complications following ureterorenoscopy versus shockwave lithotripsy. METHODS: The New York State Department of Health Statewide Planning and Research Cooperative System (SPARCS) database was used to identify 226,331 patients who underwent index ureteroscopy or shockwave lithotripsy for renal stones from 2000 to 2016. Propensity-matched generalized linear-mixed modeling was utilized to compare failure and complication rates between the two procedure groups. RESULTS: 219,383 individuals meeting inclusion criteria who underwent either ureterorenoscopy (n = 124,342) or shockwave lithotripsy (n = 95,041) in New York State between 2000 and 2016 were included in our analysis. After propensity score matching, patients undergoing shockwave lithotripsy were found to have decreased odds of experiencing any type of 30-day complication (P < 0.001 for all) but increased odds of treatment failure at both 90 (OR 1.70, 95% CI 1.64-1.77) and 180 (OR 1.83, 95% CI 1.76-1.89) days (P < 0.001 for both). CONCLUSION: Patients undergoing shockwave lithotripsy experienced significantly higher odds of treatment failure, although this undesirable outcome appears to be partially offset by lower 30-day complication rates.

Prognostic implications of prostatic urethral involvement in non-muscle-invasive bladder cancer.

PURPOSE: Non-muscle-invasive bladder cancer involving the prostatic urethra is associated with pathologic upstaging and shorter survival. We investigated the survival impact of prostatic urethral involvement in non-muscle-invasive patients who are not upstaged at cystectomy. METHODS: From 2000 to 2016, 177 male patients underwent cystectomy for high-risk non-muscle-invasive bladder cancer and remained pT1, pTis, or pTa, and N0 on final pathology; 63 (35.6%) patients had prostatic urethral involvement and 114 (64.4%) did not. Prostatic involvement was non-invasive (Ta or Tis) in 56 (88.9%) patients and superficially invasive (T1) in 7 (11.1%) patients. No patient had stromal invasion. Log-rank and Cox regression analyses were used to evaluate survival. RESULTS: Compared to patients without prostatic urethral involvement, patients with involvement were more likely to have received intravesical therapy (84.6% vs. 64.4%, p < 0.01), have multifocal tumor (90.8% vs. 51.7%, p < 0.01), and have positive urethral margins (7.7% vs. 0%, p < 0.01) and ureteral margins (18.5% vs. 5.1%, p < 0.01). Log-rank comparison showed inferior recurrence-free, cancer-specific, and overall survival in patients with prostatic involvement (p = 0.01, p = 0.03, p < 0.01). Patients with prostatic urethral involvement were more likely to experience recurrence in the urinary tract (p < 0.01). On Cox regression, prostatic urethral involvement was an independent predictor of overall mortality (HR = 2.08, p < 0.01). CONCLUSIONS: Prostatic urethral involvement is associated with inferior survival in patients who undergo cystectomy for non-muscle-invasive bladder cancer and remain pT1, pTis, or pTa on final pathology. Prostatic urethral involvement is thus an adverse pathologic feature independent of its association with upstaging.

Digital next-generation sequencing identifies low-abundance mutations in pancreatic juice samples collected from the duodenum of patients with pancreatic cancer and intraductal papillary mucinous neoplasms.

OBJECTIVE: Secretin-stimulated pancreatic juice contains DNA shed from cells lining the pancreatic ducts. Genetic analysis of this fluid may form a test to detect pancreatic ductal neoplasia. DESIGN: We employed digital next-generation sequencing ('digital NGS') to detect low-abundance mutations in secretin-stimulated juice samples collected from the duodenum of subjects enrolled in Cancer of the Pancreas Screening studies at Johns Hopkins Hospital. For each juice sample, digital NGS necessitated 96 NGS reactions sequencing nine genes. The study population included 115 subjects (53 discovery, 62 validation) (1) with pancreatic ductal adenocarcinoma (PDAC), (2) intraductal papillary mucinous neoplasm (IPMN), (3) controls with non-suspicious pancreata. RESULTS: Cases with PDAC and IPMN were more likely to have mutant DNA detected in pancreatic juice than controls (both p<0.0001); mutant DNA concentrations were higher in patients with PDAC than IPMN (p=0.003) or controls (p<0.001). TP53 and/or SMAD4 mutations were commonly detected in juice samples from patients with PDAC and were not detected in controls (p<0.0001); mutant TP53/SMAD4 concentrations could distinguish PDAC from IPMN cases with 32.4% sensitivity, 100% specificity (area under the curve, AUC 0.73, p=0.0002) and controls (AUC 0.82, p<0.0001). Two of four patients who developed pancreatic cancer despite close surveillance had SMAD4/TP53 mutations from their cancer detected in juice samples collected over 1 year prior to their pancreatic cancer diagnosis when no suspicious pancreatic lesions were detected by imaging. CONCLUSIONS: The detection in pancreatic juice of mutations important for the progression of low-grade dysplasia to high-grade dysplasia and invasive pancreatic cancer may improve the management of patients undergoing pancreatic screening and surveillance.

Duodenal Involvement is an Independent Prognostic Factor for Patients with Surgically Resected Pancreatic Ductal Adenocarcinoma.

BACKGROUND: The current staging system for pancreatic ductal adenocarcinoma (PDAC) includes information about size and local extension of the primary tumor (T stage). The value of incorporating any local tumor extension into pancreatic staging systems has been questioned because it often is difficult to evaluate tumor extension to the peri-pancreatic soft tissues and because most carcinomas of the head of the pancreas infiltrate the intra-pancreatic common bile duct. This study sought to evaluate the prognostic implications of having PDAC with local tumor extension. METHODS: A single-institution, prospectively collected database of 1128 patients who underwent surgical resection for PDAC was queried to examine the prognostic significance of extra-pancreatic tumor involvement ("no involvement," "duodenal involvement," and "extensive involvement"; e.g., gastric, colon or major vein involvement). RESULTS: The median overall survival for the patients without extra-pancreatic involvement was 26 months versus 19 months for the patients with duodenal involvement and 16 months for the patients with extensive involvement (p < 0.001). In the multivariable analysis, duodenal and extensive involvement independently predicted increased risk of death compared with no involvement (hazard ratio [HR] 1.30; 95% confidence interval [CI] 1.08-1.57 and 1.78; 95% CI 1.25-2.55, respectively). A multivariable model combining duodenal and extensive extra-pancreatic involvement, tumor grade, lymph node ratio, and other prognostic features had the highest c-index (0.67). CONCLUSIONS: Inclusion of duodenal involvement in the staging of PDAC adds independent prognostic information.

KRAS and guanine nucleotide-binding protein mutations in pancreatic juice collected from the duodenum of patients at high risk for neoplasia undergoing endoscopic ultrasound.

BACKGROUND & AIMS: Pancreatic imaging can identify neoplastic cysts but not microscopic neoplasms. Mutation analysis of pancreatic fluid after secretin stimulation might identify microscopic neoplasias in the pancreatic duct system. We determined the prevalence of mutations in KRAS and guanine nucleotide-binding protein α-stimulating genes in pancreatic juice from subjects undergoing endoscopic ultrasound for suspected pancreatic intraepithelial neoplasia, intraductal papillary mucinous neoplasms, or pancreatic adenocarcinoma. METHODS: Secretin-stimulated juice samples were collected from the duodenum of 272 subjects enrolled in Cancer of the Pancreas Screening studies; 194 subjects were screened because of a family history of, or genetic predisposition to, pancreatic cancer, and 78 subjects were evaluated for pancreatic cancer (n = 30) or other disorders (controls: pancreatic cysts, pancreatitis, or normal pancreata, n = 48). Mutations were detected by digital high-resolution melt-curve analysis and pyrosequencing. The number of replicates containing a mutation determined the mutation score. RESULTS: KRAS mutations were detected in pancreatic juice from larger percentages of subjects with pancreatic cancer (73%) or undergoing cancer screening (50%) than controls (19%) (P = .0005). A greater proportion of patients with pancreatic cancer had at least 1 KRAS mutation detected 3 or more times (47%) than screened subjects (21%) or controls (6%, P = .002). Among screened subjects, mutations in KRAS (but not guanine nucleotide-binding protein α-stimulating) were found in similar percentages of patients with or without pancreatic cysts. However, a greater proportion of patients older than age 50 years had KRAS mutations (54.6%) than younger patients (36.3%) (P = .032); the older subjects also had more mutations in KRAS (P = .02). CONCLUSIONS: Mutations in KRAS are detected in pancreatic juice from the duodenum of 73% of patients with pancreatic cancer, and 50% of asymptomatic individuals with a high risk for pancreatic cancer. However, KRAS mutations were detected in pancreatic juice from 19% of controls. Mutations detected in individuals without pancreatic abnormalities, based on imaging analyses, likely arise from small pancreatic intraepithelial neoplasia lesions. ClinicalTrials.gov no: NCT00438906 and NCT00714701.

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.

Microdissection Testicular Sperm Extraction.

Nonobstructive azoospermia (NOA) is among the most common causes of male infertility. For men with NOA seeking fertility treatment, microdissection testicular sperm extraction (microTESE) is the best option for retrieving sperm, which can be used with in vitro fertilization-intracytoplasmic sperm injection to achieve pregnancy in their partner. With the aid of the operating microscope, microTESE allows for thorough evaluation of the testis tissue and selection of seminiferous tubules that appear most capable of sperm production. Rates of success with microTESE vary depending on the underlying cause of NOA and the center at which the procedure is performed. Not all patients are candidates for microTESE, and those who are candidates should be counseled on the likelihood of sperm retrieval and the potential for changes in postoperative testis function.

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.
