INTRODUCTION: Renal cell carcinoma (RCC) is the most common renal malignancy-bone metastases (BM) are indicative of aggressive disease with a poor prognosis. We aim to evaluate the overall mortality of patients with RCC with and without BM, and to elucidate the effects of bone-remodeling therapy on mortality, incidence of skeletal-related events, and opioid usage patterns in patients with BM.

METHODS: A retrospective cohort study was conducted using TriNetX, a large, collaborative network sourced from electronic medical records of over 110 million patients from over 100 healthcare organizations. All adult patients with RCC and RCC with BM were queried.

RESULTS: There …

Low Utilization Of Intracavernosal Injection And Penile Doppler Ultrasound In The Evaluation Of Erectile Dysfunction And Peyronie's Disease, Joon Yau Leong, Tyler Gaines, Zachary J. Prebay, David Ebbott, Paul H. Chung

Department of Urology Faculty Papers

INTRODUCTION: Despite the diagnostic value of intracavernosal injections (ICI) and penile Doppler ultrasound (PDUS), there remain barriers to widespread clinical adaptation of these methods. The study aimed to evaluate the practice patterns of utilization of ICI and PDUS in the assessment of erectile dysfunction (ED) and Peyronie's disease (PD).

METHODS: Using the TriNetX database (Cambridge, MA, USA), adult (≥18 years) male patients with a diagnosis of ED on oral phosphodiesterase-5 (PDE5) inhibitors were identified. Current Procedural Terminology codes were utilized to identify patients who underwent further evaluation with ICI or PDUS, as well as penile prosthesis placement after PDUS. A …

Faculty, Staff and Students Publications

Hypogonadism is understudied in men requiring solid organ transplants, particularly among lung transplant recipients. Improvement in serum testosterone levels has been reported in kidney and liver transplantation. Using the TriNetX Research Network, we performed a retrospective cohort study to evaluate the incidence of peri-transplant hypogonadism and the natural course of serum testosterone following successful lung transplantation. Men aged ≥ 18 with a lung transplant and total testosterone drawn within one year pre- and post-transplant were included. Men with receipt of testosterone therapy were excluded. A low testosterone (< 300 ng/dL) and normal testosterone (≥300 ng/dL) cohort was created before employing descriptive and analytic statistics to investigate the incidence of peri-transplant hypogonadism and the change in serum testosterone levels following lung transplantation. In our entire cohort, lung transplantation was not associated with a significant increase in post-transplant serum testosterone (329.86 ± 162.56 ng/dL pre-transplant and 355.13 ± 216.11 ng/dL post-transplant, p = 0.483). The number of men with low testosterone decreased by 9.8% following lung transplantation but was not significant, p = 0.404. In this pilot study, no significant change in the number of hypogonadal men nor serum testosterone levels was observed among men undergoing lung transplantation.

Background: Testosterone deficiency results from insufficient testosterone production. Testosterone therapy may require dose titration to reach eugonadal serum testosterone concentrations.

Objective: The primary objective was the efficacy of oral testosterone undecanoate (TLANDO; Antares Pharma Inc.) in male patients with documented hypogonadism. Secondary objectives included a comparison of oral testosterone undecanoate safety and quality-of-life assessments to 1.62% topical testosterone gel (AndroGel 1.62%; AbbVie).

Materials and methods: In this phase 3 study, 315 patients were randomized 2:1 to oral testosterone undecanoate or 1.62% topical testosterone gel (NCT02081300). Patients received 225 mg oral testosterone undecanoate twice daily, and doses were adjusted …

Renal Mass Imaging Modalities: Does Body Mass Index (Bmi) Matter?, Young Son, Mark E. Quiring, Raeann M. Dalton, Brian Thomas, Noah Davidson, Dayna Devincentz, Collin Payne, Sahil H. Parikh, Benjamin A. Fink, Thomas Mueller, Gordon Brown

Jefferson Health - New Jersey Papers

PURPOSE: Accurate measurement of renal mass size is crucial in the management of renal cancer. With the burdensome cost of imaging yet its need for management, a better understanding of the variability among patients when determining mass size remains of urgent importance. Current guidelines on optimal imaging are limited, especially with respect to body mass index (BMI). The aim of this study is to discern which modalities accurately measure renal mass size and whether BMI influences such accuracy.

METHODS: A multi-institutional chart review was performed for adult patients undergoing partial or radical nephrectomy between 2018 and 2021, with 236 patients …

Specific Gravity Improves Identification Of Clinically Significant Quantitative Proteinuria From The Dipstick Urinalysis, Meredith C Mcadams, L Parker Gregg, Pin Xu, Song Zhang, Michael Li, Ella Carroll, Vaishnavi Kannan, Duwayne L Willett, S Susan Hedayati

Faculty, Staff and Students Publications

KEY POINTS: Urine albumin-to-creatinine ratio and urine protein-to-creatinine ratio are frequently obtained and represent possible tools for screening for proteinuria and thus early CKD. Adding specific gravity to dipstick proteinuria improves the ability to screen patients with clinically significant proteinuria and can be used to identify patients with early CKD.

BACKGROUND: CKD is often underdiagnosed during early stages when GFR is preserved because of underutilization of testing for quantitative urine albumin-to-creatinine ratio (UACR) or urine protein-to-creatinine ratio (UPCR). Semiquantitative dipstick proteinuria (DSP) on urinalysis is widely obtained but not accurate for identifying clinically significant proteinuria.

METHODS: We identified all patients …

Faculty, Staff and Student Publications

Objectives:

A number of neuro-urology imaging studies have mainly focused on investigating the brain activations during micturition in healthy and neuropathic patients. It is, however, also necessary to study brain functional connectivity (FC) within bladder-related regions in order to understand the brain organization during the execution of bladder function. This study aims to identify the altered brain network associated with bladder function in multiple sclerosis (MS) women with voiding dysfunction through comparisons with healthy subjects via concurrent urodynamics (UDS)/fMRI.

Materials and Methods:

Ten healthy adult women and nine adult ambulatory women with clinically stable MS for ≥ 6 months and …

The Significance Of Functional Renal Obstruction In Predicting Pathologic Stage Of Upper Tract Urothelial Carcinoma., Michael J. Amirian, Kushan Radadia, Hadley Narins, Kelly A. Healy, Scott G. Hubosky, Demetrius H. Bagley, Edouard J. Trabulsi, Costas D. Lallas

Department of Urology Faculty Papers

BACKGROUND AND PURPOSE: Assessing the severity of upper tract urothelial carcinoma (UTUC) has been difficult because of inadequate biopsy specimens. Additional predictive parameters of disease stage would be useful when deciding a treatment plan; it has been suggested that preoperative hydronephrosis can be a surrogate. We examined the relationship between preoperative ipsilateral renal obstruction identified by imaging with final pathologic stage after nephroureterectomy (NU) for UTUC. We then analyzed those patients with ipsilateral renal obstruction and examined if tumor location is associated with an advanced pathologic stage.

METHODS: Patients who underwent NU for UTUC between the years 2001 to 2013 …

Prevention Of Stone Migration With The Accordion During Endoscopic Ureteral Lithotripsy., Christopher J Pagnani, Magdy El Akkad, Demetrius H Bagley

Department of Urology Faculty Papers

BACKGROUND AND PURPOSE: Endoscopic lithotripsy is often prolonged secondary to the retrograde migration of calculous fragments. Various balloons, baskets, and other devices have been used to prevent this migration. Our purpose is to analyze the effect of the Accordion(®) on stone migration and overall efficiency during lithotripsy.

PATIENTS AND METHODS: We prospectively evaluated 21 patients with a total of 23 distal ureteral stones. Patients underwent lithotripsy using an endoscopic impact lithotriptor. The Accordion was randomly used in 11 of these 21 patients. Data were collected regarding stone migration, stone size, stone ablation, ureteral clearing, and lengths of time for various …

Collecting Duct Carcinoma Of The Kidney: An Immunohistochemical Study Of 11 Cases., Andrea Vecchione, Tommaso Prayer Galetti, Marina Gardiman, Hideshi Ishii, Enrico Giarnieri, Francesco Pagano, Leonard G Gomella, Carlo M Croce, Raffaele Baffa

Department of Urology Faculty Papers

BACKGROUND: Collecting duct carcinoma (CDC) is a rare but very aggressive variant of kidney carcinoma that arises from the epithelium of Bellini's ducts, in the distal portion of the nephron. In order to gain an insight into the biology of this tumor we evaluated the expression of five genes involved in the development of renal cancer (FEZ1/LZTS1, FHIT, TP53, P27kip1, and BCL2). METHODS: We studied eleven patients who underwent radical nephrectomy for primary CDC. All patients had an adequate clinical follow-up and none of them received any systemic therapy before surgery. The expression of the five markers for tumor initiation …
