Obesity is associated with many significant physiological changes. These considerations are important to surgery, especially in urological procedures. Obese patients often undergo surgical procedures and are at higher risk of complications. This investigation reviews physiological and anaesthesia considerations for obese and morbidly obese patients. In addition, urological surgeries and procedures should be considered for these higher risk patients. Clinical anaesthesiologists must use detailed assessment and, when appropriate, consultation in developing safe anaesthesia plans for these patients. Newer technologies have improved safety related to airway management, advanced airway devices, and regional anaesthesia with ultrasound-guided nerve blocks, which can reduce the need …

Silent Arterio-Ureteral Fistula: Diagnosis And Endovascular Management, Ahmed Awad, Bader Abou Shaar, Rodrick C Zvavanjanja

Faculty, Staff and Student Publications

We report a patient with history of recurrent invasive rectal adenocarcinoma complicated by obstructive uropathy requiring nephro-ureteral catheter placement. Two years later during a regular catheter exchange, the patient developed unusually bloody urine raising suspicion for possible vascular injury. CT angiogram and conventional angiogram were negative. However, an antegrade nephrostogram revealed a fistulous communication between the right ureter and the right internal iliac artery. Subsequently, the artery was sacrificed using detachable coils. We discuss the rare encounter of a silent arterio-ureteral fistula, the value of antegrade nephrostogram as a diagnostic tool, and the management options in such scenario.

Lower urinary tract symptoms (LUTS) are highly prevalent in individuals with multiple sclerosis (MS). However, assessment of these symptoms is often hindered by vague definitions or absence of screening in asymptomatic patients. It is crucial to exercise caution when applying the non-neurogenic definition of urinary retention in this population. For men with MS experiencing persistent and treatment-resistant LUTS, urodynamic studies should be used to identify the underlying causes of symptoms. Although numerous therapies are presently accessible for managing LUTS in MS, there is a need for further investigation into emerging treatments such as percutaneous tibial nerve, and noninvasive brain stimulation.

Piezo1 Regulates Meningeal Lymphatic Vessel Drainage And Alleviates Excessive Csf Accumulation, Dongwon Choi, Eunkyung Park, Joshua Choi, Renhao Lu, Jin Suh Yu, Chiyoon Kim, Luping Zhao, James Yu, Brandon Nakashima, Sunju Lee, Dhruv Singhal, Joshua P Scallan, Bin Zhou, Chester J Koh, Esak Lee, Young-Kwon Hong

Piezo1 regulates multiple aspects of the vascular system by converting mechanical signals generated by fluid flow into biological processes. Here, we find that Piezo1 is necessary for the proper development and function of meningeal lymphatic vessels and that activating Piezo1 through transgenic overexpression or treatment with the chemical agonist Yoda1 is sufficient to increase cerebrospinal fluid (CSF) outflow by improving lymphatic absorption and transport. The abnormal accumulation of CSF, which often leads to hydrocephalus and ventriculomegaly, currently lacks effective treatments. We discovered that meningeal lymphatics in mouse models of Down syndrome were incompletely developed and abnormally formed. Selective overexpression of …

Effect Of Continuous Renal Replacement Therapy On Serum Levels Of Inflammatory Cytokines/Interleukin-17 In Severe Acute Pancreatitis, Diana Iosif, Adrian Paul Suceveanu, Marius Prazaru, Iulia Cindea, Viorel Gherghina, Anca Mihaela Pantea Stoian, Laura Mazilu, Dragos Serban, Alina Nicoara, Andra Iulia Suceveanu

Despite continuous investigations in the diagnosis and treatment of severe acute pancreatitis (SAP), this disease still remains a critical condition with a mortality rate of up to 35%. The pathophysiology of SAP involves an important inflammatory reaction of the pancreas (mediated by inflammatory cytokines and immune system activation), causing severe local tissue damage as well as important systemic imbalances. IL-17 is an inflammatory mediator that have a pivotal role in SAP evolution, generating multiple interactions between inflammatory cytokines and significantly influencing the immune system response. Consequently, continuous renal replacement therapy/CRRT was added to the conventional therapy, leading to improved treatment …

Department of Radiology Faculty Papers

Objectives

The objective of this study is to validate a hypothesis that a non-invasive optical imaging assay targeting genomic VPAC receptors on malignant cells shed in voided urine will represent either benign prostatic hyperplasia (BPH) or prostatic cancer (PCa). Risk for BPH in men 50–70 years old is 50–70% and PCa is 17%. BPH and PCa can coexist in 20% of men with BPH. Most commonly practiced methods to diagnose BPH do not distinguish BPH from PCa.

Males with BPH (N = 97, 60.8 ± 6.3 years, prostate-specific antigen 0.7 ± 0.4 ng/mL) and …

Parp-Ish: Gaps In Molecular Understanding And Clinical Trials Targeting Parp Exacerbate Racial Disparities In Prostate Cancer, Moriah L. Cunningham, Matthew J. Schiewer

Department of Urology Faculty Papers

PARP is a nuclear enzyme with a major function in the DNA damage response. PARP inhibitors (PARPi) have been developed for treating tumors harboring homologous recombination repair (HRR) defects that lead to a dependency on PARP. There are currently three PARPi approved for use in advanced prostate cancer (PCa), and several others are in clinical trials for this disease. Recent clinical trial results have reported differential efficacy based on the specific PARPi utilized as well as patient race. There is a racial disparity in PCa, where African American (AA) males are twice as likely to develop and die from the …

School of Medicine Faculty Publications

Background: African ancestry is a known factor associated with the presentation and aggressiveness of prostate cancer (PC). Hispanic/Latino populations exhibit varying degrees of genetic admixture across Latin American countries, leading to diverse levels of African ancestry. However, it remains unclear whether genetic ancestry plays a role in the aggressiveness of PC in Hispanic/Latino patients. We explored the associations between genetic ancestry and the clinicopathological data in Hispanic/Latino PC patients from Colombia. Patients and methods: We estimated the European, Indigenous and African genetic ancestry, of 230 Colombian patients with localized/regionally advanced PC through a validated panel for genotypification of 106 Ancestry …

Objective Assessment Of Rupture Parameters In Intact And Acute Post-Cystorrhaphy Cadaveric Bladders, Geoffrey D. Towers, Dani G. Zoorob, Rose A. Maxwell, Ashley N. Reid, Jerome L. Yaklic, Jason C. Massengill

Obstetrics and Gynecology Faculty Publications

Background: Certain procedures, particularly those used to treat symptoms of bladder pain syndrome/interstitial cystitis (BPS/IC), involve filling the bladder to or over its capacity for visualization and/or relief of symptoms. Rarely, if excessive pressure or volume is used, bladders may rupture causing significant harm to the patient. The purpose of this study was to identify baseline data for pressure and volume when hydrodistention is attempted in explanted cadaveric bladders, as well as determine bladder rupture pressure changes in the acute post-cystorrhaphy state. Methods: Eight explanted cadaveric bladders were filled using a systematic digital pump system. Intravesical pressure and volume were …

Faculty, Staff and Student Publications

INTRODUCTION: Gender inequality has been prevalent in the history of medicine, specifically within surgical specialties. Though there have been advances, urology has remained overwhelmingly male-dominant, with slow growth in female recruitment. This survey study evaluated whether gender-related differences in the perception of urology are present among future applicants that could account for gender disparity seen in recruitment.

METHODS: An anonymized, online survey was distributed to medical students enrolled at the Max Rady College of Medicine during the 2022-2023 semester. Attracting and deterring survey statements were created using current literature to guide topics of interest. Participants rated each statement using a …

Department of Urology Faculty Papers

Background and objective

Radiation therapy has increasingly been used in the management of pelvic malignancies. However, the use of radiation continues to pose a risk of a secondary malignancy to its recipients. This study investigates the risk of secondary malignancy development following radiation for primary pelvic malignancies.

Methods

A retrospective cohort review of the Surveillance, Epidemiology, and End Results database from 1975 to 2016 was performed. Primary pelvic malignancies were subdivided based on the receipt of radiation, and secondary malignancies were stratified as pelvic or nonpelvic to investigate the local effect of radiation.

Recent technological advances have created new opportunities for performing biomarker studies within the National Cancer Institute’s (NCI’s) National Clinical Trials Network (NCTN) clinical trials. These new platforms yield more robust measurements when tissue and blood handling is optimized. At the same time, there is a strong interest in banking tissue and derivatives, such as DNA and RNA, for future biomarker studies using novel platforms that may emerge during the intervening time to trial completion. The NCI recently hosted a Clinical Trials Planning Meeting focused on two trial concepts for bladder preservation in patients with high-risk non-muscle invasive bladder cancer (NMIBC) …

PURPOSE: Germline genetic testing (GT) is important for prostate cancer (PCA) management, clinical trial eligibility, and hereditary cancer risk. However, GT is underutilized and there is a shortage of genetic counselors. To address these gaps, a patient-driven, pretest genetic education webtool was designed and studied compared with traditional genetic counseling (GC) to inform strategies for expanding access to genetic services.

METHODS: Technology-enhanced acceleration of germline evaluation for therapy (TARGET) was a multicenter, noninferiority, randomized trial (ClinicalTrials.gov identifier: NCT04447703) comparing a nine-module patient-driven genetic education webtool versus pretest GC. Participants completed surveys measuring decisional conflict, satisfaction, and attitudes toward GT at …
