Program Directors' Perspectives on Residency Applications in the Post‒United States Medical Licensing Examination Step 1 Era: A Case for Standardized Letters of Recommendation?

INTRODUCTION: The United States Medical Licensing Examination (USMLE) Step 1 test evolved into a key metric utilized by program directors (PDs) in assessing candidates for residency. The transition to a USMLE Step 1 binary pass/fail scoring system has resulted in a loss of an important objective assessment. With national movements toward pass/fail systems for clerkship grading and trends toward abandonment of class ranking, assessing residency applications has become increasingly challenging. METHODS: The Society of Academic Urologists convened a task force to, in part, assess the perspectives of urology PDs regarding the importance of various aspects of a residency application for predicting clinical performance. An anonymous survey was disseminated to all urology PDs in the US. Perspectives on 11 potential application predictors of clinical performance and demographics were recorded. Descriptive statistics characterized PD responses. Friedman test and pairwise Wilcoxon tests were used to evaluate the relative ranks assigned to application elements by PDs. RESULTS: There was a 60.5% response rate (89/147). Letters of recommendation (LORs) were ranked as the most important predictor, with a mean rank of 2.39, median of 2 (IQR 1-3). Clerkship grades and USMLE Step 1 were comparable and ranked second. Medical school reputation ranked the lowest. There was significant subjective heterogeneity among categories; however, this was less so for LORs, which predominated as the most important factor among application elements (P < .001). CONCLUSIONS: To our knowledge, this is the largest sample size assessing PD perspectives on application factors that predict clinical performance. The second (clerkship grades) and third (USLME Step 1) most important factors moving toward binary pass/fail systems create an opportunity for actionable change to improve assessment objectivity. Our data demonstrate LORs to be the most important factor of residency applications, making a compelling argument for moving toward a standardized LOR to maximize this tool, mitigate bias, and improve interreviewer reliability.

Urinary Metabolic Disturbances During Topiramate Use and their Reversibility Following Drug Cessation.

OBJECTIVE: To understand the metabolic disturbances of stone formers currently taking topiramate and to examine the reversibility of these disturbances with cessation of the medication. MATERIALS AND METHODS: All progress notes written by 5 endourologists from a single academic center were retrospectively reviewed from January 2010 to July 2020 containing the words "topiramate" or "topamax." Inclusion criteria were age >18 and presence of either a 24-hour urine sample or stone analysis while on topiramate. In addition, a subgroup of 18 patients with 24-hour urine samples before and after stopping topiramate were identified. RESULTS: A total of 93 patients were identified and included for final analysis. Twenty-four hour urine samples were available in 67 patients and showed mean citrate excretion of 331 ± 322 mg/d, mean pH of 6.6 ± 0.5, and mean calcium phosphate supersaturation of 1.9 ± 1.1. In the subgroup analysis urinary citrate excretion increased from 225 mg/d to 614 mg/d (P <.01) and pH decreased from 6.59 ± 0.54 to 6.33 ± 0.47 (P = .06) after stopping topiramate. In addition, 114 stone events occurred in 73 distinct patients, with 50% of stones either pure or majority (≥50%) calcium phosphate by composition. CONCLUSION: Hypocitraturia and elevated pH is seen during topiramate use with resultant higher rate of calcium phosphate stone formation compared to the general population. Stopping topiramate leads to significant increase in citrate excretion and normalization of pH. These metabolic disturbances appear to be reversible with medication cessation.

Resolution of Hydronephrosis and Pain to Predict Stone Passage for Patients With Acute Renal Colic.

OBJECTIVE: To study patients who presented to the Emergency Department with acute renal colic to determine if resolution of hydronephrosis and pain accurately predicts stone passage on follow-up CT. MATERIALS AND METHODS: This is a secondary analysis of a multicenter prospective randomized clinical trial of patients diagnosed by computed tomography (CT) scan with a symptomatic ureteral stone < 9 mm in diameter. Participants were followed after randomization to evaluate for analgesic use and to assess stone passage and hydronephrosis on a repeat CT scan obtained at 29-36 days. RESULTS: Four-hundred-three patients were randomized in the original study and patients were included in this analysis if they did not have surgery for stone removal and had a CT scan and information on pain medication at follow-up (N = 220). Hydronephrosis was detected in 181 (82%) on initial CT. At follow-up CT, 43 (20%) participants had a persistent ureteral stone. Of these patients, 36 (84%) had no pain, 26 (60%) did not have hydronephrosis, and 23 (53%) had neither pain nor hydronephrosis. Resolution of hydronephrosis was associated with stone passage (RR 4.6, 95% CI 1.9, 11.0), while resolution of pain was not (RR 1.1, 95% CI 0.9, 1.4). CONCLUSION: In patients with urinary stone disease, stone passage is associated with resolution of hydronephrosis but not resolution of pain. In patients with persistent ureteral stones, neither pain nor hydronephrosis are consistently present. These findings have important implications on follow-up imaging of patients with urinary stone disease.

Resident Duty Hour Compliance and Sleep after Transitioning to a Night Float System: A Prospective Observational Study in an Academic Urology Program.

INTRODUCTION: Our urology residency program transitioned to a night float system, where dedicated residents cover nights and are off duty during the day. Junior residents previously covered 5 hospitals every 5 to 7 nights and worked the following day (home call). This prospective observational study compared the 2 systems before and after the transition. METHODS: A validated survey was administered to residents and faculty to evaluate patient care, communication, quality of life, resident education, and duty hour violations. A separate survey was administered to nurses evaluating the on-call resident. Sleep was measured using actigraphy. RESULTS: Survey response rates were 80% to 100%. Junior residents rated night float as equivalent to home call for surgical case volume and superior in all other respects (p <0.05). Senior residents rated night float as superior for continuity of care, compassion, safety, efficiency for the day team, communication with nurses, quality of life, and time for reading and research (p <0.05). Faculty rated night float as superior for efficiency for the day team, handoffs, quality of life, and time for research (p <0.05). Nurses rated night float higher for availability, knowledge of plan for patient, respectfulness, communication, and ability to identify the resident on call (p <0.05). Mean duration of sleep was 2.5 and 7.1 hours for home call and night float, respectively (p <0.001). Junior residents reported fewer violations of the 80-hour and 8-hour-off rules with night float (p <0.001). CONCLUSIONS: Physicians and nurses perceived night float to improve multiple domains. Residents slept more and had fewer duty hour violations on night float.

Analgesic and Opioid Use for Patients Discharged from the Emergency Department with Ureteral Stones.

Objective: The aim of this study was to describe and characterize the analgesic and opioid use for patients discharged from the emergency department (ED) with renal colic due to ureteral stone. Methods: This is a secondary analysis of a multicenter prospective trial of ED patients diagnosed by CT scan as having a symptomatic ureteral stone <9 mm in diameter. Participants were contacted after randomization on days 2, 7, 15, 20, and 29 and reported opioid and nonopioid analgesic use and stone passage. CT scan was repeated on day 29 to 36 to confirm passage. Results: Of 403 participants, 314 (77.9%) took an analgesic after discharge and 199 (49.4%) took opioids. Opioids were more commonly used by younger patients (p = 0.04) and those with a family history of stones (p = 0.003). Stone size and tamsulosin use were not associated with analgesic utilization. Shorter time to passage and more distal stone location were associated with less analgesic and opioid use. For those who did not expel a stone, 55.0% took opioids at any time, and for those who did expel a stone, 31.9% took opioids before the stone was expelled and 15.7% took opioids at any time after the stone was expelled. Conclusions: Factors associated with increased use of analgesics in patients discharged from the ED include a longer time to stone passage, no spontaneous passage, and proximal position of the stone in the ureter. Some patients continued to use analgesics after the stone had passed, but most stopped using analgesics by day 29. The study has been registered at https://clinicaltrials.gov (NCT00382265).

Accuracy of Patient Reported Stone Passage for Patients With Acute Renal Colic Treated in the Emergency Department.

OBJECTIVE: To study patients who initially presented to the Emergency Department with acute renal colic to determine if patient-reported stone passage detects stone expulsion as accurately as follow-up computed tomography (CT) scan. METHODS: This is a secondary analysis of a multi-center prospective trial of patients diagnosed by a CT scan with a symptomatic ureteral stone <9 mm in diameter. Patient-reported stone passage, defined as capture or visualization of the stone, was compared to CT scan-confirmed passage performed 29-36 days after initial presentation. RESULTS: Four-hundred-three patients were randomized in the original study and 21 were excluded from this analysis because they were lost to follow-up or received ureteroscopic surgery. Of the 382 remaining evaluable patients, 237 (62.0%) underwent a follow-up CT scan. The mean (standard deviation) diameter of the symptomatic kidney stone was 3.8 mm (1.4). In those who reported stone passage, 93.8% (91/97) demonstrated passage of the symptomatic ureteral stone on follow-up CT. Of patients who did not report stone passage, 72.1% (101/140) demonstrated passage of their stone on follow-up CT. CONCLUSIONS: For patients who report capture or visualization of a ureteral stone, a follow-up CT scan may not be needed to verify stone passage. For patients who do not capture their stone or visualize stone passage, imaging should be considered to confirm passage.

Effect of Tamsulosin on Passage of Symptomatic Ureteral Stones: A Randomized Clinical Trial.

Importance: Urinary stone disease is a common presentation in the emergency department, and α-adrenergic receptor blockers, such as tamsulosin, are commonly used to facilitate stone passage. Objective: To determine if tamsulosin promotes the passage of urinary stones within 28 days among emergency department patients. Design, Setting, and Participants: We conducted a double-blind, placebo-controlled clinical trial from 2008 to 2009 (first phase) and then from 2012 to 2016 (second phase). Participants were followed for 90 days. The first phase was conducted at a single US emergency department; the second phase was conducted at 6 US emergency departments. Adult patients were eligible to participate if they presented with a symptomatic urinary stone in the ureter less than 9 mm in diameter, as demonstrated on computed tomography. Interventions: Participants were randomized to treatment with either tamsulosin, 0.4 mg, or matching placebo daily for 28 days. Main Outcomes and Measures: The primary outcome was stone passage based on visualization or capture by the study participant by day 28. Secondary outcomes included crossover to open-label tamsulosin, time to stone passage, return to work, use of analgesic medication, hospitalization, surgical intervention, and repeated emergency department visit for urinary stones. Results: The mean age of 512 participants randomized to tamsulosin or placebo was 40.6 years (range, 18-74 years), 139 (27.1%) were female, and 110 (22.8%) were nonwhite. The mean (SD) diameter of the urinary stones was 3.8 (1.4) mm. Four hundred ninety-seven patients were evaluated for the primary outcome. Stone passage rates were 50% in the tamsulosin group and 47% in the placebo group (relative risk, 1.05; 95.8% CI, 0.87-1.27; P = .60), a nonsignificant difference. None of the secondary outcomes were significantly different. All analyses were performed according to the intention-to-treat principle, although patients lost to follow-up before stone passage were excluded from the analysis of final outcome. Conclusions and Relevance: Tamsulosin did not significantly increase the stone passage rate compared with placebo. Our findings do not support the use of tamsulosin for symptomatic urinary stones smaller than 9 mm. Guidelines for medical expulsive therapy for urinary stones may need to be revised. Trial Registration: ClinicalTrials.gov Identifier: NCT00382265.

The Efficacy of Tadalafil Daily vs on Demand in the Treatment of Erectile Dysfunction: A Systematic Review and Meta-analysis.

We present a review comparing the use of tadalafil daily vs on-demand for erectile dysfunction. We examined randomized controlled trials and observational studies that examined the use of tadalafil for at least 8 weeks of follow-up with the primary outcome of International Index for Erectile Dysfunction-Erectile Function domain. Eight studies that examined the desired dosing regimens were identified. Of these, 6 studies included the primary end point of 12 weeks. Those patients taking tadalafil daily for 12 weeks scored on average 1.82 points higher in International Index for Erectile Dysfunction-Erectile Function domain scores, although the difference may not be clinically significant (Fig. 1).

Appearance of Pyelitis Emphysematosa on Computed Tomography.

Pyelitis emphysematosa is a gas-forming infection characterized by gas located within the wall of the collecting system and renal pelvis. There are only 2 reported cases of pyelitis emphysematosa in the literature, neither of which occurred in the era of cross-sectional imaging. Here we present a case of pyelitis emphysematosa occurring in an elderly female with congenital left renal atrophy and chronic right hydronephrosis secondary to ureteropelvic junction obstruction.

Survey of Applicant Experience and Cost in the Urology Match: Opportunities for Reform.

PURPOSE: The urology match is highly competitive but there is a paucity of published data regarding the costs and barriers that applicants face. We gathered data on contributors to cost in the 2014 urology residency match. MATERIALS AND METHODS: A survey was sent to all applicants offered an interview at each of 18 participating institutions. Information on demographics, interview related costs, access to financial aid, frequency of away rotations and second look invitations was collected. RESULTS: A total of 173 respondents spent a median of $7,000 on the urology match. Applicants attended a mean of 14 interviews with an average per interview cost of $500. Overall 95% of respondents did at least 1 away rotation and 79% reported being asked to return for a second look interview at least once. Of the respondents 66% did not receive any financial aid for interviews and only 28% believed their financial aid departments provided adequate financial planning. Of those surveyed 20% indicated that their financial situation limited the number of interviews they attended. CONCLUSIONS: We estimate that $3,122,000 was spent by applicants on the 2014 urology match. One in 5 applicants reported limiting the number of interviews they attended due to financial concerns. Adequate financial planning resources were not widely available. Nearly all applicants went on an away rotation and encouragement to return for second look interviews was common. These factors may contribute to financial and regional bias in the match process, and are potential targets for reform.

De novo Angiosarcoma of a Renal Allograft.

Prolonged exposure to immunosuppressive medication is a known risk factor for the development of post-transplant malignancies. De novo angiosarcoma in the post-transplant population is extremely rare. We present an 81-year-old female who developed an angiosarcoma at the site of a functioning renal allograft and review contemporary treatment strategies for this devastating disease. The report underscores the importance of periodic surveillance for the development of malignancy in the immunosuppressed population.

Segmental testicular infarction due to minocycline-induced antineutrophil cytoplasmic antibody--positive vasculitis.

Segmental testicular infarction is an uncommon clinical entity marked by acute scrotal pain and swelling. Classically, these appear as wedge-shaped, avascular, hypoechoic lesions on a testicular ultrasound. We present a unique case of testicular infarct caused by an antineutrophil cytoplasmic antibody-positive vasculitis secondary to the use of the antibiotic minocycline. The patient's symptoms resolved with cessation of minocycline. We suggest that patients who present with otherwise unexplained testicular infarction undergo a careful review of medications to uncover a potential cause.

The impact of obesity on urine composition and nephrolithiasis management.

BACKGROUND AND PURPOSE: Several studies have reported that obese patients have a higher risk of nephrolithiasis. The purpose of this study is to investigate the effect of overweight (OW) and obesity on stone composition, type of treatment, and urine composition. METHODS: With Institutional Review Board approval, charts of adult patients who attended our dedicated stone clinic over a 5-year period starting January 2006 were reviewed. Patients were categorized into normal (body mass index 18.5-24.9), OW (25-29.9), and obese (≥30). We excluded those who did not have at least one 24-hour urine analysis. RESULTS: OW and obese patients were more likely to have previous stones, more chance to have uric acid stones, and to be treated with shockwave lithotripsy in the community, and with ureteroscopy or percutaneous nephrolithotripsy in our center. They needed more thiazide diuretics, allopurinol, and dietitian counseling. They had statistically significant (P<0.05) higher urine calcium, citrate, supersaturation calcium phosphate, uric acid, supersaturation uric acid, sodium, potassium, magnesium, phosphorus, chloride, sulfate, urine urea nitrogen, protein catabolic rate, and creatinine compared with those with normal weight. CONCLUSION: OW and obese patients have different stone composition with increased excretion of stone promoters in the urine. Stone prevention measures should be introduced during metabolic syndrome evaluation.

Predictors of immediate postoperative outcome of single-tract percutaneous nephrolithotomy.

OBJECTIVE: To evaluate the efficacy of single tract percutaneous nephrolithotomy (sPCNL) and investigate the preoperative predictive factors associated with stone clearance after sPCNL. METHODS: A retrospective review of 351 cases of sPCNL performed at a single institution by 1 of 2 endourologists between January 2000 and March 2010 was performed. The primary outcome evaluated was stone-free rate (SFR) as assessed immediately after either an initial procedure or a second-look nephroscopy performed on postoperative day 2. Preoperative patient and stone factors, including age, sex, body mass index (BMI), preoperative hematocrit and creatinine, previous surgeries, comorbidities, renal anomalies, stone size, shape, location, and history of any previous treatment to the active stone burden were included in the univariate analysis. Significant or clinically relevant factors on univariate analysis were included in a logistic regression the multivariate analysis. RESULTS: SFR after either an initial procedure or a second-look nephroscopy was 76%. On univariate analysis, rising preoperative creatinine, hypertension, increasing stone diameter, complete staghorn stone, presence of stones in the upper pole and absence of prior SWL were associated with lower SFR. Stone size, presence of stones in the upper pole, and prior SWL for the active burden were independent predictors of SFR on multivariate analysis. CONCLUSION: sPCNL is an efficient procedure to clear renal stones, especially when used in conjunction with routine second-look nephroscopy. Increasing stone size and upper pole stones are associated with lower rates of stone clearance, whereas SWL performed before percutaneous nephrolithotomy (PCNL) is associated with improved stone clearance. The role of SWL before PCNL warrants further prospective investigation.
