To address the limitations in existing urinary stone recurrence (USR) models, including failure to account for changes in 24-hour urine (24U) parameters over time and ignoring multiplicity of stone recurrences, we presented a novel statistical method to jointly model temporal trends in 24U parameters and multiple recurrent stone events. The MSTONE database spanning May 2001 to April 2015 was analyzed. A joint recurrent model was employed, combining a linear mixed-effects model for longitudinal 24U parameters and a recurrent event model with a dynamic first-order Autoregressive (AR(1)) structure.
View Article and Find Full Text PDFFungal pathogens within the urine, specifically Candida species, are a common finding amongst hospitalized patients. Risk factors for the development of candiduria involve patients with indwelling urinary drainage devices, surgical patients, patients undergoing urologic instrumentation, and diabetic patients. Candiduria often presents with an asymptomatic course but can also be a severe life-threatening process.

Continued refinements in predicting the pre-biopsy probability of CSC are essential for optimal patient counseling. We investigated potential factors related to improved cancer detection rates (CDR) of CSC in patients with PI-RADS ≥ 3 lesions.
View Article and Find Full Text PDFBackground: We aimed to evaluate whether large prostate size, small lesion volume, or long lesion distance from the ultrasound probe tip would decrease cancer detection in transrectal magnetic resonance imaging (MRI)-targeted biopsies.
Materials And Methods: Patients who underwent MRI-targeted biopsy at our institution between May 2017 and August 2019 were enrolled in a prospective database. Three to 5 cores were obtained from ≥2 prostate imaging reporting and data system v2 lesions.
No previous works have analyzed whether the order in which surgical teams see patients on morning rounds affects discharge efficiency at teaching hospitals. We obtained perioperative urologic surgery timing data at our academic institution from 2014 to 2019. We limited the analysis to routine postoperative day 1 discharges.
View Article and Find Full Text PDFObjective: To assess the extent of formal point-of-care ultrasound (POCUS) training, current utilization of POCUS, and contemporary perceptions of POCUS amongst urologists.
Methods: A survey including questions regarding demographics, prior ultrasound education, current ultrasound utilization in practice/training, perceived optimal POCUS utilization, and the perception of formal ultrasound training was developed. The survey was disseminated to residency program directors (PDs) via the SAU and members of AUA subsection organizations.
Background: Robotic retroperitoneal partial nephrectomy (rRPN) has numerous advantages over transperitoneal surgery, including direct access to the renal hilum and posterior tumors, and avoidance of the peritoneal cavity in patients with a hostile abdomen. Although the use of the retroperitoneal approach has increased over the last decade, there is little literature on robotic retroperitoneal radical nephrectomy (rRRN), which has similar benefits over the transperitoneal approach. The aim of this study was to describe our technique for robotic retroperitoneal nephrectomy (rRN) and assess its feasibility and outcomes at a high-volume center.
View Article and Find Full Text PDFBackground: Bladder recurrence after radical nephroureterectomy (RNU) is common and randomized data supports utilization of prophylactic intravesical mitomycin to reduce recurrence. Recently, gemcitabine has been shown to be safe and effective at reducing recurrence following transurethral resection of bladder tumors. We sought to evaluate the safety and efficacy of a single, intraoperative gemcitabine instillation immediately following bladder cuff closure during RNU, and to compare outcomes with non-gemcitabine intravesical chemotherapy agents.
View Article and Find Full Text PDFObjective: To evaluate interviewer and interviewee perceptions of semiblinded interviews performed during 2021-2022 and 2022-2023 urology matches at our institution. Traditional interviews, where interviewers have access to the entire application, are open to significant bias. Blinded interviews are common in industry but under explored in resident selection.
View Article and Find Full Text PDFT3a renal masses include a diverse group of tumors that invade the perirenal and/or sinus fat, pelvicaliceal system, or renal vein. The majority of cT3a renal masses represent renal cell carcinoma (RCC) and have historically been treated with radical nephrectomy (RN) given their aggressive nature. With the adoption of minimally invasive approaches to renal surgery, the combination of improved observation, pneumoperitoneum, and robotic articulation has allowed urologists to consider partial nephrectomy (PN) for more complex tumors.
View Article and Find Full Text PDFObjectives: To assess the difference in cranio-caudal renal position in both the supine and prone position, as well as the effect of arm position on renal location, using magnetic resonance imaging in subjects with BMI <30.
Methods: In a prospective IRB approved trial, healthy subjects underwent magnetic resonance imaging in the supine, prone position with arms at the side, and prone position with arms up using vertically placed towel bolsters. Images were obtained with end expiration breath holds.
Objective: To examine the Urology residency application process, particularly the interview. Historically, the residency interview has been vulnerable to bias and not determined to be a predictor of future residency performance. Our goal is to determine the relationship between pre-interview metrics and post-interview ranking using best practices for Urology resident selection including holistic review, blinded interviews, and structured behaviorally anchored questions.
View Article and Find Full Text PDFPurpose Of Review: Urology program directors are faced with increasing numbers of applications annually, making holistic review of each candidate progressively more difficult. Efforts to streamline evaluation using traditional cognitive metrics have fallen short as these do not predict overall resident performance. Situational judgment tests (SJTs) and personality assessment tools (PATs) have been used in business and industry for decades to evaluate candidates and measure non-cognitive attributes that better predict subsequent performance.
View Article and Find Full Text PDFPurpose Of Review: Objective measures of residency applicants do not correlate to success within residency. While industry and business utilize standardized interviews with blinding and structured questions, residency programs have yet to uniformly incorporate these techniques. This review focuses on an in-depth evaluation of these practices and how they impact interview formatting and resident selection.
View Article and Find Full Text PDFWe wanted to evaluate two new treatment phases within our practice, including a nonopioid pathway, to determine the effect on opioid usage, health care utilization, and pain following ureteroscopy. Patients undergoing ureteroscopic lithotripsy were enrolled in a study utilizing text messaging to evaluate postoperative pain and opioid usage. Our historical postoperative pain regimen included #30 oxycodone.
View Article and Find Full Text PDFPurpose: The cohort of patients with locally advanced prostate cancer (PC) and positive surgical margin(s) at radical prostatectomy (RP) who would benefit from salvage or adjuvant treatment is unclear. This study examines the risk of prostate-specific antigen (PSA) relapse in a large population of men with PC after margin-positive RP.
Methods And Materials: Using a multi-institutional database, patients with clinically localized PC who underwent RP between 2002 and 2010 with recorded follow-up PSA were retrospectively selected.
Unlabelled: INTRODUCTION Androgen deprivation therapy (ADT) is often used in the treatment of prostate cancer. Specific factors affecting testosterone recovery after cessation of ADT have not been well-characterized in existing literature.
Materials And Methods: We retrospectively reviewed patients at our institution who received ADT between 1999 and 2018.
