Association Of Perioperative Factors With Lymph Node Positivity In Bladder Cancer Following Radical Cystectomy, Alyssa Laguerta, Kimberly Toumazos, Virgil Kevin Demario, Vaishnavi Patel, Balaji Reddy, Mark Quiring, Evan Jones, Young Son, Ronald Clearie, Thomas Mueller

Rowan-Virtua Research Day

Introduction and objectives: The treatment of bladder carcinoma relies on a multimodal approach, including chemotherapy, radical cystectomy, and lymph node dissection, but clear guidelines for the optimal strategy remain ambiguous. Radical cystectomy is complex, with high morbidity and mortality, yet limited research has focused on its short-term implications for lymph node-positive bladder cancer. This study aims to address these gaps by identifying perioperative factors linked to lymph node positivity and comparing outcomes between lymph node-positive and negative patients.

Methods: We conducted a retrospective analysis of 4382 bladder cancer patients who underwent radical cystectomy, collecting comprehensive clinical and surgical data. Clinical …

Ultrasonographic Appearance Of Suspected Zinner Syndrome, Wen Hao Luo, Jared Garfinkle, Jack Hennen, Robert Martin, Kathleen Deiling

Rowan-Virtua Research Day

Zinner syndrome (ZS) is a rare congenital condition characterized by the triad of unilateral renal agenesis, ipsilateral seminal vesicle cyst, and ipsilateral ejaculatory duct obstruction. ZS is suspected to be caused by the malformation of the mesonephric duct during embryogenesis. The incomplete migration of the ureteric bud results in ipsilateral renal agenesis and ejaculatory duct obstruction. The remaining gonad develops with inadequate seminal fluid drainage, leading to the formation of seminal vesicle cysts. ZS is often asymptomatic, leading to challenges in diagnosis, particularly in adolescents. Symptoms can include pain, dysuria, pollakisuria, perineal pain, epididymitis, and pain after ejaculation. Imaging plays …

Hydralazine-Induced Vasculitis Resulting In Large Pleural Effusion And Progressive Renal Dysfunction, Michael A. Acevedo, Hammad Choudhry

Rowan-Virtua Research Day

Hydralazine is a vasodilator commonly used to treat high blood pressure. Even with the safety profile of Hydralazine, it is necessary to know that it may lead to Hydralazine-Induced Vasculitis. Here, we discuss how this rare side effect can present in an 80-year-old female with a past medical history of hypertension who presented to the emergency department with complaints of progressive shortness of breath on exertion and while lying supine. Further evaluation revealed a large right-sided pleural effusion with consolidation at the right lower lobe. The patient’s dyspnea worsened, and the surgical team placed a chest tube. The patient also …

Impact Of Fluid Composition On Mortality And Kidney Injury In Sepsis: A Literature Review, Kush C. Patel, Simran Gandhi, Harmann Singh, Abdullah Noory, Akash M. Patel

Rowan-Virtua Research Day

Background

Fluid resuscitation is a cornerstone of early sepsis management. While normal saline (NS) has been widely used, emerging evidence suggests that balanced crystalloids such as lactated Ringer’s and Plasma-Lyte may offer improved renal outcomes and reduced mortality by avoiding hyperchloremic metabolic acidosis.

Hypothesis

In adult patients with sepsis, initial resuscitation with balanced crystalloids reduces mortality and the incidence of acute kidney injury (AKI) compared to normal saline.

Methods

A literature review was conducted using PubMed and MEDLINE databases focusing on randomized controlled trials and meta-analyses published from 2010–2024. Key studies included the SMART, SALT-ED, BaSICS, and PLUS trials. The …

The Repercussions Of Race-Based Egfr On The Morbidity & Mortality Of Black Children With Renal Disease, Angelina Siino

Rowan-Virtua Research Day

This study investigates the implications of race-based adjustments in estimated glomerular filtration rate (eGFR) calculations on the health outcomes of Black children with renal disease. Historically, a race coefficient has been added to eGFR calculations for patients identified as Black, resulting in an artificial inflation of kidney function by approximately 16%. This inflation can delay the classification of chronic kidney disease (CKD), postpone eligibility for essential interventions like preemptive kidney transplantation, and prolong reliance on maintenance dialysis. Through a comprehensive literature review of peer-reviewed U.S. medical journal articles published between 2000 and 2023, this work explores how these clinical delays …

A Systematic Review On Cinacalcet’S Effect In Reducing Pth Serum Levels In Peritoneal Dialysis Patients, Akhil Gumidyala, Youssef Daoud, Mark Hanna, Han Jie Liu, Rikita Doshi

Rowan-Virtua Research Day

Background: Patients with Chronic Kidney Disease (CKD) have low calcium levels. Low blood calcium triggers the parathyroid gland to constantly secrete parathyroid hormone (PTH) in an attempt to raise blood calcium levels back to normal. One way PTH tries to do this is by removing calcium from bone. Chronically high PTH levels leads to increased bone resorption and increases the risk for bone fractures and mortality risk. This phenomenon is called secondary hyperparathyroidism (SHPT). Calcimimetics, like cinacalcet (sensipar), act similarly to calcium by binding allosterically to Calcium-Sensing Receptors (CaSR) on the parathyroid gland, thereby reducing PTH levels. The effect of …

We report the case of a 26-year-old male with a significant psychiatric and substance use history who came to the emergency department (ED) with deep partial second degree burns to his back subsequent to using a heating pad for unknown periods of time prior to presentation. Rhabdomyolysis and acute kidney injury that occurred in this patient due to his burns. It is important to understand that although beneficial, if heating pads are misused or overused, they can cause injury.

Case Report: Herba Epimedium (Horny Goat Weed) Toxicity With Severe Muscle Spasms And Elevated Creatine Kinase And Creatinine, Tucker A. Ledo, Dhara Patel, Wayne Tamaska, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Here we present the case of a 33-year-old male who presented to the emergency department (ED) with a complaint of severe muscle spasms of a ten-hour duration. He noted that he took a supplement which he purchased over the internet called Epimedium, also known as Horny Goat Weed, for the purpose of improving his mood and sense of energy and reducing his sense of anxiety. He noted that he started this supplement one month prior to ED presentation, coincident with the first episodes of muscle cramps. In the ED, he had elevations of his CK and creatinine and required hospital …

A Rare Case Of Diffuse Alveolar Hemorrhage In The Setting Of Iga Nephropathy, Vasculitis And Atypical Hemolytic Uremic Syndrome In A Previously Healthy Young Adult, Karl Schlicht, Nancy Kaura

Rowan-Virtua Research Day

IgA Nephropathy, also known as Berger disease, can precipitate acute renal failure in patients. IgA Nephropathy (IgAN) is deposition of protein from IgA into the renal tissue with subsequent renal dysfunction. IgA vasculitis (IgAV) is another condition where similarly the protein of IgA is deposited into the vessels. There are some cases of co-existing atypical hemolytic uremic syndrome (aHUS) with IgAN. However, rare combinations seen with all three IgAN, IgAV, and aHUS without any pre-existing conditions nor medical history. Patients that develop any one of these conditions are looking at life long changes with hemodialysis (HD) and organ transplants being …

Brash Syndrome Case Report And Brief Review, Kelly Schuitema

Rowan-Virtua Research Day

BRASH syndrome is an acronym that stands for bradycardia, renal failure, AV node blocker, shock and hyperkalemia. The syndrome is precipitated by synergism from AV nodal blocking agents and hyperkalemia. The combination of the AV nodal blockade and renal failure leads to a cycle of severe bradycardia and hyperkalemia. We will discuss a case of BRASH syndrome with a 68 year old female who presented with generalized weakness and was found to be hypotensive, bradycardia, in acute renal failure with hyperkalemia likely related to metoprolol and amlodipine use.

Factors Associated With Unplanned Conversion To Open In Nephrectomy For Kidney Cancer, Young Son, Benjamin A. Fink, Justine Garfinkel, Lance Earnshaw, Brian Thomas, Thomas Mueller, David Sussman

Rowan-Virtua Research Day

Minimally invasive surgery (MIS) has been adopted as an approach in kidney surgery. Laparoscopic kidney surgery has been introduced in the 1990s with robotics emerging a decade after. The minimally invasive approach has been technically feasible and has been shown to be noninferior with preserved oncology standards to open surgery. The ubiquitous use of MIS for kidney cancer has been standard of practice; however, unplanned conversion to open kidney surgery has been characterized at 4.9% for laparoscopic radical nephrectomy compared to 6.0% in robotic radical nephrectomy. Another analysis of 54,246 patients undergoing partial nephrectomy for kidney cancer observed an unplanned …

Digoxin Toxicity And Acute Renal Failure In A 75 Year-Old Female, Daniel Zaayenga, Andrew Caravello, Nicholas Tomasello

Rowan-Virtua Research Day

Digoxin toxicity can present with varying manifestations. While pathognomonic symptoms such as xanthopsia (object appearing yellow) are a board favorite it is not a required finding and is in fact not seen with most patients. Rather digoxin toxicity presents with more non-specific symptoms such as GI distress (anorexia, N/V) neurological distress (lethargy, fatigue, delirium, confusion, disorientation, weakness. EKG findings are varied and include premature ventricular contractions, bradycardia, atrial tachyarrhythmias with AV block, ventricular bigeminy, junctional rhythms, various degrees of AV nodal blockade, ventricular tachycardia, and ventricular fibrillation. Although rarely seen, digoxin is one of the only causes of bidirectional ventricular …

A Hidden Cause For Electrolyte Derangement In The Ed: Gitelman Syndrome, Alexis Dunn, James Espinosa, Alan Lucerna, Kevin Dwyer

Rowan-Virtua Research Day

Electrolyte derangements are a common finding in the emergency department, whether incidental or the cause for presenting symptoms. Gitelman syndrome (GS) can be the cause for recurrent hypokalemia and hypomagnesemia. While often diagnosed when the patient is young, a clinician should keep this on the differential when seeing repeated visits with electrolyte deficiencies and treating them. Here we discuss a case of how Gitelman syndrome has presented in the ED and what to learn from it.

Case Study Of Metformin-Induced Lactic Acidosis, Kajel Patel, Kishan B. Patel

Rowan-Virtua Research Day

Metformin induced lactic acidosis is when high levels of metformin cause dangerously high levels of lactic acid. Here is a case report of a 72-year-old female who came in for nausea, vomiting, and diarrhea found to have a high suspicion for metformin induced lactic acidosis. She stabilized in the emergency department, nephrology and ICU was contacted, and she went for emergent dialysis. For many patients the prognosis of metformin induced lactic acidosis is poor. This patient was made comfort care by her family.

Incidental Finding Of Unusually Large Renal Cyst During Point Of Care Ultrasound, David Ho, Jeffrey Gardecki

Rowan-Virtua Research Day

Renal cysts are common, and their frequency and size increase as patients age. Renal cysts are derived primarily from tubules and can occur anywhere between Bowman’s capsule to the renal papilla. The cysts are composed of abnormally differentiated epithelial cells encapsulating a cavity of fluid. These abnormally differentiated cells are due to defects in the structure and function of cilia, the structures responsible for detecting urine flow as well as the epithelial composition of the epithelial architecture and repair. According to Campbell Urology, there are three processes in which renal cysts increase in their size – proliferation of epithelial cells …

Long-Term Lithium Use In The Younger Population: Do The Benefits Outweigh The Risks? - A Case Report, Seema Shekar, Alexander Garcia, Rachel Shmuts

Rowan-Virtua Research Day

For decades lithium has been the mainstay treatment for bipolar disorder. While its side effect profile is extensive and varied its most notable adverse effect, and one most feared by treating clinicians, is nephrotoxicity/ end-stage renal disease (ESRD). While the link between long-term lithium use and ESRD has been accepted by the medical community at large for many years, more recent scientific studies call the association into question. In fact, newer studies on the association between Li use and ESRD have shown a negative/inconclusive correlation. Despite this controversy the consensus still remains that ESRD secondary to long-term Li use is …

Retrospective Analysis Of Post-Operative Sepsis Rates, Stone Composition, And Ureteral Stent Duration After Ureteroscopy And Laser Lithotripsy During Covid-19, Young Son, Julia T. Scali, Ian Madison, Paul Chialastri, Thomas Mueller

Rowan-Virtua Research Day

Ureteroscopy with laser lithotripsy is routinely used to remove stones but results in manipulation of the genitourinary mucosa and has a well-established relationship with post-operative sepsis under certain conditions. Postoperative sepsis represents a significant morbidity and mortality cost to patients and the healthcare system. Several studies to determine risk factors for sepsis after ureteroscopy have been completed. Such risk factors include positive preoperative urine cultures, female gender, prolonged preoperative stent time > 1 month, and patients with sepsis at the time of initial stenting. To improve sepsis rates, procedural alterations such as the use of disposable ureteroscopes have been introduced, as …

Case Report: Holmium Laser Removal Of Antegrade Ureteral Stent Suture Via Ureteroscopy, Paul Chialastri, Jerome Pietras, Thomas Mueller

Rowan-Virtua Research Day

Antegrade placement of ureteral stents is common after nephrostomy tube placement for obstruction in the septic patient and when retrograde placement fails. Ureteral stents have a nylon retaining suture attached to aid in placement. If left in place accidentally, these will not degrade and will become embedded in the renal parenchyma preventing stent removal and potentially leading to infection and stone formation. Ureteroscopic holmium ablation of the residual suture at the level of the parenchyma allows for stent removal and no urothelial defect was noted on repeat ureteroscopy 3 weeks later. Ureteroscopy with holmium lasering of retained suture appears safe …

Postoperative Cholecystitis From Nathanson Liver Retractor During Robotic-Assisted Laparoscopic Partial Nephrectomy, Lauren D. Gleich, Mihir G. Thaker, Gordon A. Brown

Rowan-Virtua Research Day

Proper visualization of the surgical field during any procedure is one of the most imperative elements of surgery. The tools used to obtain this goal come with their own set of risks. This report describes a patient who developed postoperative acalculous cholecystitis (PAC) after use of a Nathan liver retractor. PAC is a rare complication of urologic surgery and is often more severe than acalculous cholecystitis (AC), leading to significant morbidity.

Chronic Renal Failure, But Why? A Case Report., Palak Patel, Michael Rothberg

Rowan-Virtua Research Day

Renal failure, both acute and chronic, can present from many different etiologies and if diagnosed with diabetes mellitus, it is commonly assumed to be due to diabetic nephropathy. Monoclonal gammopathy of renal significance (MGRS) is a disorder that combines monoclonal gammopathy of undetermined significance with end stage renal disease. Monoclonal immunoglobulins are secreted by B or plasma cells leading to deposition in the kidney causing end organ damage. Several different subtypes fall under this category of renal diseases including, but not limited to, amyloidosis, C3 glomeruopathy, and light chain proximal tubulopathy, or better known as Fanconi syndrome1. Fanconi syndrome, which …

A Case Of Atraumatic Posterior Thigh Compartment Syndrome, Nailah Mubin, Brian Katt

Rowan-Virtua Research Day

Compartment syndrome(CS) occurs when intra-compartmental pressures exceeds to a point where arterial, venous and lymphatic circulation of local tissues, muscles and nerves is compromised. CS is most common after a traumatic injury and usually occurs in the leg or forearm and less commonly in the thigh. Thigh compartment syndrome is rare due to its larger size and more compliant borders. We present a case of nontraumatic compartment syndrome in the posterior thigh associated with rhabdomyolysis and a sciatic nerve palsy which then required emergent fasciotomy. The patient's course was further complicated by acute renal failure due to the rhabdomyolysis and …
