Primary Retroperitoneal Mucinous Cystadenocarcinoma: A Case Report.

Mucinous neoplasms are commonly seen in the ovaries and pancreas. Their occurrence in the retroperitoneum is uncommon. We present a case of a retroperitoneal mucinous cystadenocarcinoma in a 54-year-old female who presented with right flank pain.

National Implementation and Evaluation of a Virtual Subinternship in Urology.

Objective: To conduct a nationwide evaluation of student and program director (PD) perspectives of virtual subinternships that took place during the COVID-19 pandemic.

Materials And Methods: In December 2020, we distributed anonymous surveys to all 534 urology residency applicants and 161 urology PDs at academic medical centers across the United States to evaluate virtual subinternships. Surveys assessed curriculum composition, goals, satisfaction, barriers, and future reusability.

Feasibility and Utility of Mobile Applications for the Evaluation of Urology Residents' Surgical Competence.

Objective: To provide real-time assessment and feedback on the competency of urology residents' surgical skill via mobile applications and examine their feasibility and utility.

Materials And Methods: Two mobile application-based systems (SIMPL and myTIPreport) were sequentially implemented for the case-by-case assessment of residents' performance of surgical skills at a single institution. Data was collected regarding residents' perception of their feedback pre- and post-implementation of the applications.

Laser scanner for 3D reconstruction of a wound's edge and topology.

Purpose: Robotic systems have the potential to overcome inherent limitations of humans and offer substantial advantages to patients including reduction in surgery time. Our group has undertaken the challenge of developing autonomous wound closure system. One of the initial steps is to allow accurate assessment of wound skin topology and wound edge location.

Can preoperative renal mass biopsy change clinical practice and reduce surgical intervention for small renal masses?

Introduction: The role of renal biopsy prior to surgical intervention for a renal mass remains controversial despite the fact that for all other urological organs except the testicle, biopsy inevitably precedes treatment as is true for all other specialties dealing with solid masses (e.g. thyroid, breast, colon, liver, etc.

Patient Safety in the Operating Room During Urologic Surgery: The OR Black Box Experience.

Purpose: To mitigate intraoperative adverse events, it is important to understand the context in which these errors occur. The purpose of this study is to characterize the IAEs and potential distractions that occur in minimally invasive urologic procedures.

Methods: We conducted a prospective cohort study in patients undergoing laparoscopic urologic surgery at an academic health center.

Changing the Status Quo: Developing a Virtual Sub-Internship in the Era of COVID-19.

Problem: Subinternships are integral to medical education as tools for teaching and assessing fourth-year medical students. Social distancing due to COVID-19 has precluded the ability to offer in-person subinternships - negatively impacting medical education and creating uncertainty surrounding the residency match. With no precedent for the development and implementation of virtual subinternships, the Society of Academic Urologists (SAU) developed an innovative and standardized curriculum for the Virtual Subinternship in Urology (vSIU).

Prognostic Molecular Signatures for Metastatic Potential in Clinically Low-Risk Stage I and II Clear Cell Renal Cell Carcinomas.

For patients with localized node-negative (Stage I and II) clear cell renal cell carcinomas (ccRCC), current clinicopathological staging has limited predictive capability because of their low risk. Analyzing molecular signatures at the time of nephrectomy can aid in understanding future metastatic potential. Develop a molecular signature that can stratify patients who have clinically low risk ccRCC, but have high risk genetic changes driving an aggressive metastatic phenotype.

Laparoscopic Partial Nephrectomy.

Renal cell carcinoma has historically been managed by radical nephrectomy, but as knowledge of the disease has advanced, nephron sparing surgery has become the norm in appropriately selected tumors. Laparoscopic partial nephrectomy (LPN) has been shown to have comparable oncologic outcomes and a shorter convalescence period compared to the traditional open partial nephrectomy. Dissemination of techniques has led to significantly increased use of minimally invasive nephron sparing surgery, and LPN remains a cost-effective and efficacious method for approaching small renal masses.

Primary renal Ewing Sarcoma masquerading as Wilms in an adolescent female.

Primary renal Ewing's sarcoma (ES) of the kidney represents a rare oncologic entity belonging to the collection of small round cell tumors, which typically feature osseous presentations. Renal ES is an aggressive disease entity with high metastatic potential, either at time of presentation or following initial extirpative therapy. Herein, we report the case of a 14-year-old female who initially presented with intermittent gross painless hematuria and a large left renal mass identified on ultrasound and confirmed on follow up MRI.

Weighted Gleason Grade Group (WGGG): A new prostate cancer biopsy reporting system with prognostic potential.

Introduction: Presently, prostate biopsy (PBx) results report the highest Gleason Grade Group (GGG) as a single metric that gauges the overall clinical aggressiveness of cancer and dictates treatment. We hypothesized a PBx showing multiple cores of cancer with more volume cancer per core would represent more aggressive disease. We propose the Weighted Gleason Grade Group (WGGG), a novel scoring system that synthesizes all histopathologic data and cancer volume into a single numeric value representing the entire PBx, allowing for improved prediction of adverse pathology and risk of biochemical recurrence (BCR) following radical prostatectomy (RP).

Best Practice Statement on Urologic Procedures and Antimicrobial Prophylaxis.

Purpose: The primary rationale for antimicrobial prophylaxis (AP) is to decrease the incidence of surgical site infection (SSI) and other preventable periprocedural infections, with the secondary goal of reducing antibiotic overuse. This Best Practice Statement (BPS) updates the prior American Urological Association (AUA) BPS and creates a comprehensive and user-friendly reference for clinicians caring for adult patients who are undergoing urologic procedures.

Materials And Methods: Recommendations are based on a review of English language peer-reviewed literature from 2006 through October 2018 and were made by consensus by a multidisciplinary panel.

Multi-institutional Evaluation of Producing and Testing a Novel 3D-Printed Laparoscopic Trainer.

Objective: To create, distribute, and evaluate the efficacy of a portable, cost-effective 3D-printed laparoscopic trainer for surgical skills development.

Methods: The UCI Trainer (UCiT) laparoscopic simulator was developed via computer-aided designs (CAD), which were used to 3D-print the UCiT. Once assembled, a tablet computer with a rear-facing camera was attached for video and optics.

Laparoscopic Completion Nephrectomy for Local Surgical Bed Recurrence After Partial Nephrectomy: An Analysis of Procedural Complexity and Feasibility.

Objectives: To study the feasibility and perioperative outcomes associated with a laparoscopic approach to completion nephrectomy in patients with locoregional disease recurrence after partial nephrectomy (PN) for renal cell carcinoma.

Patients And Methods: We performed a retrospective review of patients who underwent PN between 2006 and 2016 and developed locoregional recurrence, defined by the presence of new disease within the original surgical bed. Those undergoing planned laparoscopic completion nephrectomy constituted the study cohort.

Implementation of multiparametric magnetic resonance imaging technology for evaluation of patients with suspicion for prostate cancer in the clinical practice setting.

Objectives: To investigate the impact of implementing magnetic resonance imaging (MRI) and ultrasonography fusion technology on biopsy and prostate cancer (PCa) detection rates in men presenting with clinical suspicion for PCa in the clinical practice setting.

Patients And Methods: We performed a review of 1 808 consecutive men referred for elevated prostate-specific antigen (PSA) level between 2011 and 2014. The study population was divided into two groups based on whether MRI was used as a risk stratification tool.
