Abstract Introduction: Women, underrepresented minorities, and international medical graduates are underrepresented in urology. We sought to compare demographics of leaders in academic urology to urology faculty and academic medical faculty.
Materials and methods: The Association of American Medical Colleges provided academic medical faculty demographics. Women, underrepresented minorities, and international medical graduates in leadership roles (department/division chair or full professor) were identified. Fisher’s exact tests were performed to compare proportions of those groups in urology leadership to academic urology, academic medicine leadership, and academic medicine.
Results: In 2019, there were 179,105 faculty in academic medicine with 41,766 in leadership and… More >

Abstract Introduction: The use of alvimopan at the time of cystectomy has been associated with improved perioperative outcomes. Naloxegol is a less costly alternative that has been used in some centers. This study aims to compare the perioperative outcomes of patients undergoing cystectomy with urinary diversion who receive the mu-opioid antagonist alvimopan versus naloxegol.
Materials and methods: This was a retrospective review that included all patients who underwent cystectomy with urinary diversion at our institution between 2007-2020. Comparisons were made between patients who received perioperative alvimopan, naloxegol and no mu-opioid antagonist (controls).
Results: In 715 patients who underwent cystectomy,… More >

Abstract Introduction: The BD PureWick System (PureWick) allows for non-invasive management of urinary incontinence (UI) by using a low-pressure suction to wick urine from an external catheter into a collection canister. The purpose of this study was to assess satisfaction of using PureWick for management of UI in the outpatient setting based on patient and caregiver feedback.
Materials and methods: Patients and caregivers utilizing PureWick completed an online questionnaire between August and October 2020. Factors evaluated included demographics, satisfaction, recommendations, and claims using multiple choice questions, checklists, 6-point Likert Scale, and open-ended questions. Patient and caregiver responses were… More >

Abstract Prostate-specific antigen (PSA) screening remains the mainstay for early detection of prostate cancer. Although PSA is a nonspecific prostate cancer biomarker, its specificity for high grade prostate cancer can be enhanced by pre-biopsy liquid biomarkers including the Exosome Dx Prostate IntelliScore (EPI) test.
EPI is a stand-alone urine genomic test that measures 3 exosome-derived gene expression signatures without the need for digital rectal examination (DRE) or inclusion of standard of care parameters in the test algorithm. EPI has broad clinical utility as a risk stratification tool for clinically significant high grade prostate cancer in men More >

Abstract Introduction: Ureteral stent-related symptoms are common after stent placement. Various characteristics of stent design have been previously investigated to mitigate this issue. Our review summarizes available literature on stent design parameters (diameter, material, position, length, distal loop modifications) and their effect on stent-related symptoms, including pain.
Materials and methods: We identified articles from PubMed, Medline, EMBASE, Web of Science, and Grey Literature using a search strategy employing MESH search headings (i.e., ureteral stent diameter, length, composition, material, durometer, and stent-related pain).
Results: Out of 2,970 identified studies, 26 met eligibility criteria. Most diameter studies found patients with >… More >

Abstract Introduction: To uncover factors associated with an increased likelihood of a postoperative triage phone call from caregivers after pediatric ambulatory urologic surgery with a focus on social determinants of health.
Materials and methods: This was a retrospective cohort study from July 2014-January 2020. Patients undergoing ambulatory urologic surgery by three different pediatric urologists were included. The primary outcome was the number of patient families that called within 30 days after surgery. Univariable tests and multivariable logistic regression analysis were used to identify factors associated with the increased likelihood of a postoperative phone call.
Results: The families of 460… More >

Abstract Introduction: Despite widespread usage, research on the relationship of marijuana use to disease is sorely lacking. We sought to test the relationship of LUTS/BPH treatment and endocannabinoid agonist usage, as well as alcohol usage and depression, with treatment for LUTS/BPH in our health system.
Materials and methods: We queried our hospital system database of nearly three million patients in a marijuana-legalized region for data from the electronic medical record between January 2011 and October 2018. Men over the age of 45 on medical therapy for LUTS (selective alpha blockade and/or finasteride) were included. Exclusions were diagnosis of… More >

Abstract Introduction: Peyronie’s disease (PD) is a fibrous transformation of the tunica albuginea within the corpora cavernosa causing curvature of the penis while erect. This cannot only be painful but can also cause narrowing, shortening, an hourglass deformity and problems with penetrative intercourse.
There are many means of management of Peyronie’s disease at the time of penile implant. Modeling is a commonly used approach but leaves the penis without increased length. Multi-incisional techniques enhance length restoration, but risk significant vascular and neurologic compromise. Herein, we present our experience with a novel algorithm to approach Peyronie’s disease with… More >

Abstract Scrotal lymphangiomas represent an extremely rare cause of scrotal swelling. We report a case of scrotal lymphangioma in an 18-year-old male who presented with painful scrotal swelling. Scrotal ultrasound revealed a complex multicystic structure in the left hemiscrotum. The patient underwent successful surgical excision of the mass. Postoperatively, he developed a hydrocele which eventually spontaneously regressed. Histopathology confirmed the diagnosis. We outline the unusual presentation, characteristic imaging and histology findings, and surgical management of scrotal lymphangiomas. With this information, urologists may exercise a heightened level of awareness for this rare cause of scrotal swelling. More >

Abstract We present the case of a 73-year-old male patient who presented with obstructive urinary symptoms, pelvic pressure, and hematuria. CT imaging revealed a heterogenous prostate enlargement, and MRI demonstrated the mass to be arising from the seminal vesicle. Prostate biopsies showed benign tissue. Surgical excision was completed and pathology revealed it to be an epithelioid smooth muscle neoplasm of uncertain biologic potential. This is only the second known case of such a seminal vesicle tumour. As soft tissue sarcomas of the seminal vesicle emerge in the literature, we may develop a better understanding of their More >
