Implementation of a Urologic Surgery Skills Fair for Medical Students

To increase the proportion of applicants to urology residencies, we created a surgical skills fair to introduced urology early in undergraduate medical education. Funded by the Department of Urology, the fair was designed to have student rotations through 12 hands-on practice stations supervised by faculty and an advanced care practitioner or resident physicians. At conclusion, medical students completed a voluntary survey about their experience. Surgical skills fairs were organized at Yale School of Medicine (New Haven, CT) in 2022 and 2023. The fair was designed to encourage interaction between medical students, urology residents, and urology faculty by highlighting common urologic procedures and skills. The fair was well received by medical students at all levels of training. Over 2 years, 155 medical students attended, including 67 (43%) first-year and 60 (39%) second-year medical students. Eighty-two medical students completed the survey. An average of 19 attendings, advanced care practitioners and residents attended each event. Of the survey respondents, 42.7% reported prior interest in a surgical specialty but had not considered urology. Students reported increased interest in urology and greater confidence in urologic skills after the event (p < 0.001). We demonstrate that creating a surgical fair in urology is feasible and enhances early exposure and interest in urology. For students who do not pursue urology, the fair provides knowledge of urological pathologies and valuable skills for all physicians.

Implementing Change Through an Outpatient Antibiotic Stewardship Program.

We sought to implement a multi-pronged behavioral intervention to reduce and tailor antibiotic use for two common urologic outpatient procedures. This study was a non-blinded intervention study that consisted of a pre-intervention phase (11/2018-1/2019), an intervention phase (1/2020-12/2020) in which a multi-pronged behavioral intervention was implemented, and a post-intervention phase (1/2021-3/2021). We examined antibiotic use for cystoscopy and transrectal prostate biopsy at three separate urologic outpatient clinics. A multi-pronged behavioral intervention consisted of formal physician education, modification of the electronic health order sets, clinic staff education, literature review, development and introduction of patient questionnaires, and individual audit feedback. The primary outcome was 30-day infections. Secondary outcomes were adherence to the recommended antibiotic protocols, questionnaire completion, and Escherichia coli outpatient antibiograms. A total of 2374 patients underwent 3047 cystoscopies and 547 patients underwent 559 prostate biopsies. The proportions of cystoscopy patients receiving antibiotic prophylaxis and prostate biopsy patients receiving augmented antibiotic prophylaxis decreased 33% and 35%, respectively. The odds of post-cystoscopy infection were not different between the pre-intervention and intervention phases and were lower in the post-intervention phase. The odds of post-biopsy infection were not changed between the pre-intervention and intervention or between the pre-intervention and post-intervention phases. Implementing a multi-pronged behavioral intervention reduced and tailored antibiotic use without an increase in 30-day infections. These findings suggest that outpatient antibiotic stewardship and facilitating rapid adoption of guidelines can be accomplished via this approach.

Practices of Informed Written Consent for Elective Urological Procedures at a Tertiary Care Hospital in Sudan.

Objective This study aimed to assess informed consent practices in elective urological surgeries at a tertiary care facility. Materials and methods A retrospective cross-sectional survey was carried out between March 1, 2023and April 1, 2023, at the Department of Urology, Omdurman Military Hospital, Sudan. We included all patients who had undergone elective urological procedures under local, spinal, or general anesthesia. The medical records were accessed to analyze the consent forms' standards. A total of 42 consent forms were included and analyzed. We use the General Medical Council's (GMC) Guidance on Professional Standards and Ethics for Doctors: Decision Making and Consent, and the Royal College of Surgeons (RCS) of England's Consent: Supported Decision-Makingas the standard for our study. The GMC and the RCS of England have provided comprehensive and standardized guidelines for obtaining informed written consent, including indications, benefits, risks involved, and alternatives in addition to demographics, patient details, responsible consultant, diagnosis, and title of the surgery, intended benefits, probable risks, type of anesthesia, consenting doctor's name, designation, and signature, and the patient's signature and name. Results A total of 42 consent forms were included. The diagnosis and the intended surgical procedure were mentioned in all consents. The potential benefits and risks were discussed in 36 (85.7%) and 18 (42.9%) cases, respectively. The type of anesthesia was discussed in 39 (92.9%) of cases. The likely result of not having the procedure and the alternative treatment: Recorded completion rates of 10 (23.8%) and 12 (28.6%), respectively. Patient demographics were completely documented in 41 (97.6%) forms. Senior doctors were only involved in 14 (33.3%) of the consents. Details of the consenting doctor, including name, title, and signature, were present in 30 cases (71.4%), and the date of signing the consent was documented in 38 cases (90.5%). The completeness of the consent form correlated with the level of the doctor obtaining it, with consultants achieving the highest completion rates (100%), followed by registrars (66.7%) and medical officers (35.7%). Conclusion The current practices of informed consent were found to be substandard. Handwritten consent forms do not adhere to the recommended guidelines for informed consent in elective urological procedures. It is preferable to utilize a pre-designed consent form, allowing for personalized additions based on the patient's specifics. Our recommendation is to organize an educational session for junior doctors to emphasize proper consent procedures, and deepen their knowledge of common urological elective procedures, and associated risks. This approach promotes adherence to best clinical practices and minimizes the risk of legal challenges.

Accuracy and Readability of Artificial Intelligence Chatbot Responses to Vasectomy-Related Questions: Public Beware.

Purpose Artificial intelligence (AI) has rapidly gained popularity with the growth of ChatGPT (OpenAI, San Francisco, USA) and other large-language model chatbots, and these programs have tremendous potential to impact medicine. One important area of consequence in medicine and public health is that patients may use these programs in search of answers to medical questions. Despite the increased utilization of AI chatbots by the public, there is little research to assess the reliability of ChatGPT and alternative programs when queried for medical information. This study seeks to elucidate the accuracy and readability of AI chatbots in answering patient questions regarding urology. As vasectomy is one of the most common urologic procedures, this study investigates AI-generated responses to frequently asked vasectomy-related questions. For this study, five popular and free-to-access AI platforms were utilized to undertake this investigation. Methods Fifteen vasectomy-related questions were individually queried to five AI chatbots from November-December 2023: ChatGPT (OpenAI, San Francisco, USA), Bard (Google Inc., Mountainview, USA) Bing (Microsoft, Redmond, USA) Perplexity (Perplexity AI Inc., San Francisco, USA), and Claude (Anthropic, San Francisco, USA). Responses from each platform were graded by two attending urologists, two urology research faculty, and one urological resident physician using a Likert (1-6) scale: (1-completely inaccurate, 6-completely accurate) based on comparison to existing American Urological Association guidelines. Flesch-Kincaid Grade levels (FKGL) and Flesch Reading Ease scores (FRES) (1-100) were calculated for each response. To assess differences in Likert, FRES, and FKGL, Kruskal-Wallis tests were performed using GraphPad Prism V10.1.0 (GraphPad,San Diego,USA) with Alpha set at 0.05. Results Analysis shows that ChatGPT provided the most accurate responses across the five AI chatbots with an average score of 5.04 on the Likert scale. Subsequently, Microsoft Bing (4.91), Anthropic Claude (4.65), Google Bard (4.43), and Perplexity (4.41) followed. All five chatbots were found to score, on average, higher than 4.41 corresponding to a score of at least "somewhat accurate." Google Bard received the highest Flesch Reading Ease score (49.67) and lowest Grade level (10.1) when compared to the other chatbots. Anthropic Claude scored 46.7 on the FRES and 10.55 on the FKGL. Microsoft Bing scored 45.57 on the FRES and 11.56 on the FKGL. Perplexity scored 36.4 on the FRES and 13.29 on the FKGL. ChatGPT had the lowest FRES of 30.4 and highest FKGL of 14.2. Conclusion This study investigates the use of AI in medicine, specifically urology, and it helps to determine whether large-language model chatbots can be reliable sources of freely available medical information. All five AI chatbots on average were able to achieve at least "somewhat accurate" on a 6-point Likert scale. In terms of readability, all five AI chatbots on average had Flesch Reading Ease scores of less than 50 and were higher than a 10th-grade level. In this small-scale study, there were several significant differences identified between the readability scores of each AI chatbot. However, there were no significant differences found among their accuracies. Thus, our study suggests that major AI chatbots may perform similarly in their ability to be correct but differ in their ease of being comprehended by the general public.

Can AI chatbots accurately answer patient questions regarding vasectomies?

Artificial Intelligence (AI) has revolutionized the healthcare industry. There have been limited studies assessing AI model efficacy and accuracy in urology. To our knowledge, there is a lack in research looking at one of the most common urological procedures: the vasectomy. Ten frequently asked questions regarding vasectomies were individually entered into three different AI sources (ChatGPT, Bard & Bing) using free interfaces available to consumers. The responses were critically analyzed by three urologists and graded on a scale of 1 to 4 for clarity, accuracy, and evidence-based information, with 1 being the best and 4 being the worst. ChatGPT had the best average rating per question at 1.367, followed by Bard at 2.167 and Bing at 1.800(p = 0.000083). ChatGPT was found to provide significantly more satisfactory answers than both Bard (p = 0.00005) and Bing (p = 0.03988). The difference between Bard and Bing however was found to be insignificant (p = 0.09651). Overall, our study shows that AI Chatbots may provide mostly accurate information on frequently asked questions regarding vasectomies and is a reasonable resource for patients interested in the procedure to use. ChatGPT is the most accurate and concise of the chatbots assessed.

Endovascular Treatment for Renal Vein Embolism by a Renal Calculus After Percutaneous Nephrolithotomy.

This report presents the endovascular strategies adopted to treat a kidney calculus venous embolism after percutaneous nephrolithotomy and the versatility of endovascular techniques to manage even the most unexpected renovascular complications after urological intervention. According to the literature available in PubMed, Cochrane, SciELO, and Science.gov repositories, this is the first case to our knowledge of renal vein calculus embolism as a complication of percutaneous treatment of kidney stones. A 62-year-old woman underwent percutaneous nephrolithotomy to treat a left kidney 2.8-cm staghorn calculi. The stone cracked, leaving a residual fragment in the ureteropelvic junction. Abdominal computed tomography revealed a 0.9-mm extrarenal calculus located inside the left retroaortic renal vein. Calculus was captured using a basket catheter system through a 6F 45-cm sheath positioned in the left common femoral vein (CFV) and accessed by dissection to safely conclude the calculus extraction by venous cut down. The patient was asymptomatically discharged 48 hours after the endovascular procedure, under a rivaroxaban anticoagulation regimen, with no symptoms or renal function impairment until the 6 months of follow-up. The endovascular strategy proposed in this case was effective for calculus rescue and venous flow restoration. This case reinforces the adaptability of endovascular therapy in an unexpected scenario. A potentially life-threatening extremely rare adverse event following a common urological procedure could be treated with minimally invasive hybrid treatment, preserving renal function and maintaining venous vascular patency. This report may add a discussion of procedures to manage similar events and bring to the literature a possible strategy to solve the problem.

Graduating resident and fellow readiness for general urologic practice during the COVID-19 pandemic A survey-based assessment of trainees and program directors.

Our goal was to compare the perceived readiness of graduating urologic residents and fellows to program directors (PDs) in U.S.-based postgraduate training programs. Additionally, we set out to assess the impact of COVID-19 on postgraduation plans to pursue fellowship training. Graduating residents, fellows, and PDs of accredited residency/fellowship programs in the U.S. were surveyed. The ranked preparedness of trainees to perform common urologic procedures was measured using a Likert scale from 1 (not comfortable) to 5 (fully proficient). The impact of COVID-19 was measured using a three-point Likert scale. Chi-squared and Kruskal-Wallis analyses were used to compare the groups. From 93 responders, 21 were residents, 19 were fellows, 24 were residency PDs, and 29 were fellowship PDs. The median levels of comfort for trans-urethral resection of the prostate, hydrocelectomy, vasectomy, and urethral sling were at or above (≥3) moderate for both PDs and trainees. PDs were more likely to report underperformance for hypospadias repair (60% vs. 39%), penile prosthesis implantation (39% vs. 26%), and orthotopic neobladder formation (57% vs. 18%) than the trainees. Fifty-three (57.0%) of the surveyors felt that COVID-19 did not impact the trainees' comfort in performing general urologic procedures. COVID-19 influenced trainees' decision to pursue a fellowship or opt to practice as general urologists (p=0.002). Our study suggests there may be a self-reported discrepancy between graduating trainees and their PDs regarding trainees' comfort levels performing general urologic procedures.

(376) High Capability of ChatGPT to Answer Common Patient Questions on Vasectomy Reviewed by Sexual Medicine Specialists

Abstract Introduction Novel technologies utilizing artificial intelligence (AI) have shown their potential to reduce provider workload and improve task efficiency in certain clinical settings. ChatGPT is an AI-powered chatbot which utilizes natural language processing (NLP) technology to provide human-like responses to open-ended questions posed by users. Recent studies have shown ChatGPT’s ability to provide diabetes counseling in lieu of trained educators, and effectively communicate technical research papers in layman’s terms to patients. Vasectomy is a common urologic clinic procedure that can be a source of anxiety for patients, many of whom desire the opportunity for further pre-operative counseling. Objective The objective of this preliminary study was to evaluate the ability of ChatGPT to respond to common patient questions on vasectomy encountered by sexual medicine specialists. Methods We composed a list of 20 questions commonly asked by patients pertaining to vasectomy. The questions were submitted to ChatGPT Plus with the prompt: “Answer the following questions in 50 words or less”. 3 fellowship-trained sexual medicine specialists then rated the accuracy of ChatGPT’s responses on a scale from 1-5 (1 representing a completely inaccurate response and 5 representing a response in line with what they would recommend to patients). Scores were tabulated and summarized (Table 1). Descriptive statistics were performed. Weighted Cohen’s kappa was calculated to assess for interrater reliability. Results Median score across all 20 responses from 3 raters was 4.1 (IQR 1.3). The most common rating was 5, indicating a high level of agreement between ChatGPT’s responses and those of sexual medicine specialists. The lowest score assigned was 2 (indicating poor accuracy), and was received by 6 responses. Weighted Cohen’s kappa was 0.49, implying moderate agreement amongst raters. Overall, ChatGPT was able to provide relatively accurate and concise responses to these common questions. Conclusions Our results demonstrate the capability of using ChatGPT as a potentially reliable source of information for patients desiring vasectomy counseling. Given the high clinical volume faced by many vasectomy providers, ChatGPT could possibly improve patient satisfaction and reduce provider burden. Further collection of real-world data is needed to better assess the accuracy and reliability of ChatGPT’s responses. Sexual medicine specialists should be aware of the strengths and limitations of emerging AI technologies as a medium for providing accurate health information to patients.

Comparative study between radiation exposure in common urological procedures

BackgroundFluoroscopy has become essential to urological surgery since advancement of endourology. Fluoroscopy use has increased, placing urologists as well as staff members at risk for occupational radiation exposure and related dangers. This study compared radiation exposure for staff personnel in percutaneous nephrolithotomy (PCNL), ureteroscopy (URS) and extracorporeal shock wave lithotripsy (ESWL). Then, study determined the maximum number of PCNL, URS and ESWL cases that staff members can handle safely each year.ResultsRadiation exposure in PCNL group was higher than URS and ESWL especially for surgeon. Dose of radiation exposure in ESWL for surgeon, assistant and nurse was 2.4 microsievert (μSv), 0.9 μSv and 0.8 μSv, respectively. Dose of radiation exposure in URS for surgeon, assistant and nurse was 18.5 μSv, 14.3 μSv and 13.1 μSv, respectively. Dose of radiation exposure in PCNL for surgeon, assistant and nurse was 73 μSv, 51.3 μSv and 47.6 μSv, respectively.ConclusionIncreased stone size and increased fluoroscopy time were associated with high radiation exposure. PCNL procedure was 8.8 times more likely to exhibit high-dose exposure than other procedures. Urologists can perform: 274 PCNL case, 1081 URS case and 8333 ESWL case per year within safe radiation exposure limits advised by International Commission on Radiation Protection (ICRP).

An analysis of flexible cystoscopic findings among patients visiting Urology outpatient services at a tertiary cancer center in Nepal

Introduction: Cystoscopy is a common urological procedure done for diagnosis and surveillance of patients with urological ailments. With various lower urinary tract symptoms, flexible cystoscopy can be performed with a minimal discomfort to the patient and in a outpatient setting under local anesthesia. Materials and Methods: We retrospectively analyzed 468 patients undergoing flexible cystoscopy from January 2022 to July 2022 over a period of six months in the outpatient services of B.P. Koirala Memorial Cancer Hospital. Results: Majority of the patients (56.2%) had some pathology of the lower urinary tract among which urinary bladder mass or malignancy was the predominant findings with 35%. Conclusion: Flexible cystoscopy is an important tool in urology with high diagnostic yield.

Rural For-Profit Hospitals Are Associated With Higher Commercial Prices for 3 Common Urological Procedures.

Rural patients lack access to urological services, and high local prices may dissuade underinsured patients from surgery. We sought to describe commercially insured prices for 3 urological procedures at rural vs metropolitan and for-profit vs nonprofit hospitals. A cross-sectional analysis of commercially insured prices from the Turquoise Health Transparency data set was performed for ureteroscopy with laser lithotripsy, transurethral resection of bladder tumor, and transurethral resection of prostate. Hospital characteristics were linked using the Centers for Medicare and Medicaid Services Healthcare Cost Reporting Information System. Linear modeling analyzed median hospital price and its association with hospital characteristics. Overall, 1,532 hospitals reported urological prices in Turquoise. Median prices for each procedure were higher at rural for-profits (ureteroscopy $16,522, transurethral resection of bladder tumor $5,393, transurethral resection of prostate $9,999) vs rural nonprofits (ureteroscopy $4,512, transurethral resection of bladder tumor $2,788, transurethral resection of prostate $3,881) and metropolitan for-profits (ureteroscopy $5,411, transurethral resection of bladder tumor $3,420, transurethral resection of prostate $4,874). Rural for-profit status was independently associated with 160% higher price for ureteroscopy (relative cost ratio 2.60, P < .001), 50% higher for transurethral resection of bladder tumor (relative cost ratio 1.50, P = .002), and 113% higher for transurethral resection of prostate (relative cost ratio 2.13, P < .001). Prices are higher for 3 common urological surgeries at rural for-profit hospitals. Differential pricing may contribute to disparities for underinsured rural residents who lack access to nonprofit facilities. Interventions that facilitate transportation and price shopping may improve access to affordable urological care.

Aquablation Treatment for Benign Prostatic Obstruction

Aquablation Treatment for Benign Prostatic Obstruction Abstract: The surgical BPH treatment is one of the most common urological procedures. With our reference methods: transurethral resection of the prostate (TUR-P), open surgical adenomenucleation over a transabdominal access, and also modern laser procedures. Various effective surgical options are available. However, the quality of the surgical outcome is highly dependent on the surgeons' experience. At the same time, all of the above-mentioned reference methods are associated with a high rate of sexual dysfunction, especially postoperative anejaculation, a symptom complex which is relevant for men, regardless of age [1]. Robotic Aquablation® was developed with the goal to reduce the dependency of the surgical outcome on the expertise of the surgeon, but at the same time achieving a comparable outcome and reduced morbidity. After the "first in human treatment" by Peter Gilling in 2013, the Aquabeam® robot has been used in its current form in clinical studies since 2015 (Water, Water II and Open Water Study) and finally was introduced in clinical routine in August 2017 by Thorsten Bach in Hamburg. The safety and effectiveness of Aquablation® therapy has been proven in various studies and in everyday clinical practice.

Unplanned 120-Day ED Visits and Readmission Rates Following Common Stone Procedures

ObjectiveTo quantify emergency department (ED) visits and hospital admissions (HA) after common urologic stone procedures including ureteroscopy (URS), shockwave lithotripsy (SWL), and percutaneous nephrolithotomy (PCL) which are a concern of payors, providers, and patients. Materials and MethodsThis is a retrospective cohort study using claims data from the IBM MarketScan Commercial and Medicare Supplement databases. Adults with a urologic stone diagnosis and no history of stone procedure in prior 12 months who underwent stone procedures between 2012 and 2017 were included. All-cause ED visits and HA were evaluated during 30, 60, 90, and 120-day periods following the index urologic stone procedure. ResultsA total of 166,287 patients were included in the analytic cohort. For inpatient-indexed procedures, cumulative ED visits rates following stone procedure at 120 days was 18.8% for URS, 19.2% for SWL, and 23.6% for PCL. A similar trend was observed with ED visit rates, following outpatient indexed procedures at 120 days with a cumulative rate of 14.2% of SWL patients, 14.9% of URS patients, and 17.3% of PCL. A similar trend was found when examining HA. ED and HA rates increased steadily through the 120-day time period. ConclusionRates of ED visits and HA following common stone procedures continue to rise at least up to 120 days following the index procedure whether in the outpatient or inpatient settings. While rates of unplanned care are similar for URS and SWL, patients undergoing PCL return to the hospital at higher rates.

Creating an Extraordinary Experience for Women Undergoing Cystoscopy: A Patient-Centered Approach to Process Improvement

ObjectiveTo re-examine and improve the cystoscopy process for women based on patient input. While cystoscopy is a common urological procedure, women perceive it as invasive, personal, and fear-inducing. Patients want to be treated as individuals and not just another “procedure.” MethodsWomen's perspectives on cystoscopy were collected using experience-based design. Observations and timings, emotion word lists, debrief forms, patient surveys, simulation, and interviews were used. A structured 2-day quality improvement event included both in-person and virtual patient participation to gain a deeper understanding of patients’ perspectives. Ideas for process improvements were generated using brainstorming, creativity exercises, and prioritization. These changes were implemented and refined using an iterative process based on feedback. ResultsPatients who reported feeling grateful for the positive impact of their care tended to minimize procedure-associated wait times, inconvenience, and discomfort. Women in the evaluation phase of their treatment and those who were unhappy with their symptoms tended to magnify the negative emotions associated with their procedure. Patient feedback and areas for improvement specific to women's needs were identified. Actionable changes were implemented including engaging clinic staff, updating the cystoscopy workflow, and physical changes to enhance patient privacy. ConclusionIdentifying and addressing the needs of women undergoing cystoscopy improves satisfaction as their emotional, physical, and knowledge-based needs are addressed. Active participation in the health care process empowers patients to have a voice in their care. An extraordinary experience with cystoscopy may decrease anxiety of the unknown and help patients have control over the experience.

Impact of preexisting opioid dependence on morbidity, length of stay, and inpatient cost of urological oncological surgery.

To determine the incidence of preexisting opioid dependence in patients undergoing elective urological oncological surgery. In addition, to quantify the impact of preexisting opioid dependence on outcomes and cost of common urologic oncological procedures at a national level in the USA. We used the National Inpatient Sample (NIS) to study 1,609,948 admissions for elective partial/radical nephrectomy, radical prostatectomy, and cystectomy procedures. Trends of preexisting opioid dependence were studied over 2003-2014. We use multivariable-adjusted analysis to compare opioid-dependent patients to those without opioid dependence (reference group) in terms of outcomes, namely major complications, length of stay (LOS), and total cost. The incidence of opioid dependence steadily increased from 0.6 per 1000 patients in 2003 to 2 per 1000 in 2014. Opioid-dependent patients had a significantly higher rate of major complications (18 vs 10%; p < 0.001) and longer LOS (4days (IQR 2-7) vs 2days (IQR 1-4); p < 0.001), when compared to the non-opioid-dependent counterparts. Opioid dependence also increased the overall cost by 48% (adjusted median cost $18,290 [IQR 12,549-27,715] vs. $12,383 [IQR 9225-17,494] in non-opioid-dependent, p < 0.001). Multivariable analysis confirmed the independent association of preexisting opioid dependence with major complications, length of stay in 4th quartile, and total cost in 4th quartile. The incidence of preexisting opioid dependence before elective urological oncology is increasing and is associated with adverse outcomes after surgery. There is a need to further understand the challenges associated with opioid dependence before surgery and identify and optimize these patients to improve outcomes.

Cost-effectiveness of routine type and screens in select urological surgeries.

To evaluate the cost-effectiveness of obtaining a preoperative type and screen (T/S) for common urologic procedures. A decision tree model was constructed to track surgical patients undergoing two preoperative blood ordering strategies as follows: obtaining a preoperative T/S versus not doing so. The model was applied to the National (Nationwide) Inpatient Sample (NIS) data, from January 1, 2006 to September 30, 2015. Cost estimates for the model were created from combined patient-level data with published costs of a T/S, type and crossmatch (T/C), a unit of pRBC, and one unit of emergency-release transfusion (ERT). The primary outcome was the incremental cost per ERT prevented, expressed as an incremental cost-effectiveness ratio (ICER) between the two preoperative blood ordering strategies. A cost-effectiveness analysis determined the ICER of obtaining preoperative T/S to prevent an emergency-release transfusion (ERT), with a willingness-to-pay threshold of $1,500.00. A total of 4,113,144 surgical admissions from 2006 to 2015 were reviewed. The overall transfusion rate was 10.54% (95% CI, 10.17-10.91) for all procedures. The ICER of preoperative T/S was $1500.00 per ERT prevented. One-way sensitivity analysis demonstrated that the risk of transfusion should exceed 4.12% to justify preoperative T/S. Routine preoperative T/S for radical prostatectomy (rate = 3.88%) and penile implants (rate = .91%) does not represent a cost-effective practice for these surgeries. It is important for urologists to review their institution T/S policy to reduce inefficiencies within the preoperative setting.

Large Variations in the Prices of Urologic Procedures at Academic Medical Centers 1 Year After Implementation of the Price Transparency Final Rule

Patients with urologic diseases often experience financial toxicity, defined as high levels of financial burden and concern, after receiving care. The Price Transparency Final Rule, which requires hospitals to disclose both the commercial and cash prices for at least 300 services, was implemented to facilitate price shopping, decrease price dispersion, and lower health care costs. To evaluate compliance with the Price Transparency Final Rule and to quantify variations in the price of urologic procedures among academic hospitals and by insurance class. This was a cross-sectional study that determined the prices of 5 common urologic procedures among academic medical centers and by insurance class. Prices were obtained from the Turquoise Health Database on March 24, 2022. Academic hospitals were identified from the Association of American Medical Colleges website. The 5 most common urologic procedures were cystourethroscopy, prostate biopsy, laparoscopic radical prostatectomy, transurethral resection of the prostate, and ureteroscopy with laser lithotripsy. Using the corresponding Current Procedural Terminology codes, the Turquoise Health Database was queried to identify the cash price, Medicare price, Medicaid price, and commercial insurance price for these procedures. The Price Transparency Final Rule, which went into effect January 1, 2021. Variability in procedure price among academic medical centers and by insurance class (Medicare, Medicaid, commercial, and cash price). Of 153 hospitals, only 20 (13%) listed a commercial price for all 5 procedures. The commercial price was reported most often for cystourethroscopy (86 hospitals [56%]) and least often for laparoscopic radical prostatectomy (45 hospitals [29%]). The cash price was lower than the Medicare, Medicaid, and commercial price at 24 hospitals (16%). Prices varied substantially across hospitals for all 5 procedures. There were significant variations in the prices of cystoscopy (χ23 = 85.9; P = .001), prostate biopsy (χ23 = 64.6; P = .001), prostatectomy (χ23 = 24.4; P = .001), transurethral resection of the prostate (χ23 = 51.3; P = .001), and ureteroscopy with laser lithotripsy (χ23 = 63.0; P = .001) by insurance type. These findings suggest that, more than 1 year after the implementation of the Price Transparency Final Rule, there are still large variations in the prices of urologic procedures among academic hospitals and by insurance class. Currently, in certain situations, health care costs could be reduced if patients paid out of pocket. The Centers for Medicare & Medicaid Services may improve price transparency by better enforcing penalties for noncompliance, increasing penalties, and ensuring that hospitals report prices in a way that is easy for patients to access and understand.

Renocolic Fistula after Extracorporeal Lithotripsy: Case Report and Literature Review of a Rare Complication of a Common Procedure

Extracorporeal lithotripsy (ESWL) is one of the most common urological procedures. Among its possible complications, renal parenchymal lesions are rare (approximately 7%). This is a case report of a renocolic fistula after ESWL. It is a very rare complication and without descriptions in the literature of association with ESWL. Because it is a rare lesion, there is no standardized treatment or data that makes it possible to determine the best conduct. The present case required a surgical approach to correct the fistula. It was possible to preserve the affected kidney, which is even rarer in the medical literature.

Post-procedural Antibiotic Use and Associated Outcomes After Common Urologic Procedures Across a National Healthcare System

ObjectiveTo quantify the benefits and harms of post-procedural antibiotic use after common urologic procedures. Materials and MethodsThis retrospective cohort study included patients who underwent an endoscopic urologic procedure (transurethral resection of bladder tumor, transurethral resection of prostate, or ureteroscopy) within the Veterans Health Administration between January 1, 2017 and June 30, 2021. A post-procedural antibiotic was any qualifying antibiotic prescribed for administration on the day after the procedure. Guidelines generally do not recommend post-procedural antibiotics for surgical prophylaxis. Outcomes included unplanned return visits and Clostridioides difficile infection within 30 days. Log-binomial models with risk-adjustment were used to measure the association between post-procedural antibiotic use and outcomes. Hospital-level observed-to-expected (O:E) ratios were constructed to compare post-procedural antibiotic use. ResultsThere were 74,629 qualifying procedures across 105 hospitals; 27,422 (36.7%) received post-procedural antibiotics (median 3 days, IQR 3-6). An unplanned return visit occurred in 20.2% of patients who received post-procedural antibiotics vs 17.2% who did not (adjusted RR 1.032, 95% CI 0.999-1.066). C. difficile infection was diagnosed in 0.27% vs 0.10% in those who received and did not receive post-procedural antibiotics (adjusted RR 1.67, 95% CI 1.13-2.45). The O:E ratio for post-procedural antibiotic use ranged from 0.46 among hospitals in the lowest-use quartile to 1.93 in the highest-use quartile. ConclusionPost-procedural antibiotics were frequently prescribed after urologic procedures with large inter-facility variability even after adjusting for case-mix differences. Post-procedural antibiotic use was associated with increased risk for C. difficile infection but not fewer unplanned return visits. Efforts to reduce guideline-discordant use of post-procedural antibiotics are needed.
