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 …


Case Report: Pigtail Suprapubic Catheter Placement In A Patient With Acute Urinary Retention And Abdominal Mesh, Clara Keum, Zamran Masih, James Espinosa, Alan Lucerna May 2025

Case Report: Pigtail Suprapubic Catheter Placement In A Patient With Acute Urinary Retention And Abdominal Mesh, Clara Keum, Zamran Masih, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Acute urinary retention (AUR) is a urological emergency that requires immediate bladder decompression and management of the underlying condition to prevent further complications such as urinary tract infection and renal failure. When standard urethral catheterization is not feasible, a suprapubic catheter can be used to achieve adequate bladder drainage. However, in patients with structural or anatomical challenges, such as the presence of surgical mesh, suprapubic catheter placement can be difficult. This case report presents the successful placement of an 8.5 French pigtail catheter and urinary drainage in an 86-year-old male with abdominal mesh who presented with AUR.

BACKGROUND: Bladder and urinary tract cancers account for approximately 21,000 new diagnoses and 5,000 deaths annually in the UK. Approximately 90% are transitional cell carcinomas where advanced disease is treated with platinum based chemotherapy and PD-1/PD-L1 directed immunotherapy. Urinary tract squamous cell carcinoma (UTSCC) accounts for about 5% of urinary tract cancers overall making this a rare disease. We have yet to establish definitive systemic treatment options for advanced UTSCC. Preliminary translational data, from UTSCC patient tumour samples, indicate high PD-L1 expression and tumour infiltrating lymphocytes in a proportion of cases. Both of these features are associated with differential gene …


Purple Urine Bag Syndrome (Pubs) In A Patient With A Chronic Indwelling Foley, Kelsey Murray, Kishan B. Patel May 2023

Purple Urine Bag Syndrome (Pubs) In A Patient With A Chronic Indwelling Foley, Kelsey Murray, Kishan B. Patel

Rowan-Virtua Research Day

Purple urine bag syndrome (PUBS) is a rare medical condition characterized by the appearance of purple discoloration in the urine collection bag of patients who use catheters for urinary drainage. PUBS is primarily seen in elderly, female, and institutionalized patients who have chronic indwelling catheters. The discoloration occurs due to the presence of certain bacteria that produce pigments, which react with the plastic materials of the catheter and urine collection bag, leading to the formation of a purple color. In addition to the aesthetic concerns, PUBS may also indicate an underlying urinary tract infection or other medical conditions that require …

Ureteral fistulas are a rare occurrence that can arise from iatrogenic trauma, radiation, malignancy, and inflammation. Treatment options of urinary tract fistulas are handled on a case-by-case basis and can necessitate a surgical approach. We present the case of an 85-year-old patient with a ureterocutaneous fistula where conservative management with PCN is a viable alternative to surgical intervention.


Pathophysiology, Presentation, And Management Of Interstitial Cystitis In The Acute Setting, David Koziel May 2023

Pathophysiology, Presentation, And Management Of Interstitial Cystitis In The Acute Setting, David Koziel

Rowan-Virtua Research Day

Interstitial cystitis (IC) also known as bladder pain syndrome (BPS) and more infrequently by other monikers represents a debilitating disease with a poorly understood pathophysiology. According to the Centers for Disease Control the incidence of IC ranges from 1 to 5.1 cases per 100,000 individuals. While a relatively rare condition, it is common enough that the provider in the acute setting recognizes the pathophysiology and is familiar with the management of this condition. It is a disease that is more prevalent in women, however men can also be affected. Due to the significant overlap with more common conditions, it is …

Case Report: Segmental Testicular Infarction, Nicholas Coan, Ronald Clearie, Amanda Maciag, Joseph Pagano, James Espinosa, Alan Lucerna, Neelesh Parikh

Rowan-Virtua Research Day

We report a case of a 45-year-old male who presented to the Emergency Department with acute onset left testicular pain and was diagnosed with left sided segmental testicular infarction. The differential diagnosis of acute onset testicular/scrotal pain can include critical urological diagnoses such as testicular torsion and testicular tumors. In the absence of global flow disruption on ultrasound Doppler, emergent surgical intervention is not needed. While ultrasound aids in the Emergency Department’s management of acute testicular pain, it does not rule out the need for an additional outpatient work-up or imaging. Conservative management with pain control, outpatient scrotal MRI, and …

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 May 2022

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 …

Department of Pathology and Laboratory Medicine

Background: The gold standard screening method of hyperoxaluria in children is using 24-hour urine collection. Urine collection may be cumbersome and challenging for children. Reference intervals (RI) of oxalate for the Pakistani population are not readily available. Therefore we aimed to determine the oxalate to creatinine ratio (Ox: Cr) for Pakistani children <6 years of age.
Materials and methods: A cross-sectional study was conducted at Aga Khan University from June 2018 to October 2019. Random urine samples from apparently healthy children < 6 years were collected and stored at -30°C until analysis after adding 6M HCl. Oxalate was measured on Micro lab 300 using a kit based on oxalate oxidase principle, while creatinine was measured by kinetic Jaffe reaction. Data was analyzed by EP evaluator and SPSS 23. Ox: Cr ratio was calculated and reported with 90% confidence interval (CI) and interquartile range (IQR).
Results: The mean age of study subjects (n=120) was 29 ±22.3 months with an M: F ratio of 1:1. Children of various ethnicities …

METHODS: ICD-10 symptom codes (e.g., dysuria) alone or in addition to UTI diagnosis codes plus prescription of a UTI-relevant antibiotic were used to identify outpatient UTI visits. Chart review (gold standard) was performed by two reviewers to confirm diagnosis of UTI. The positive predictive value (PPV) that the visit was for UTI (based on chart review) was calculated for three different ICD-10 code algorithms using (1) …


Chronic Renal Failure, But Why? A Case Report., Palak Patel, Michael Rothberg May 2019

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 …

Marshall Journal of Medicine

Autonomic dysreflexia (AD) is a life threatening condition affecting patients with spinal cord lesions T6 level and above. A 51 year old male with a history of paraplegia due to a C6 spinal cord injury (30 years prior) presented with recurrent debilitating episodic diaphoresis, hypertension, low body temperature, and bradycardia. Previous hospitalizations presumed sepsis from UTI to be the etiology, however on further evaluation his symptoms were consistent with undiagnosed AD. This article describes a unique case presentation and reviews AD in depth, including the etiology, pathophysiology and management.


Characterization Of Bacterial Pathogens Involved In Aerobic Vaginitis: Prevalence, Strain Characterization And Sequelae, Leslie A. Lafferty May 2016

Characterization Of Bacterial Pathogens Involved In Aerobic Vaginitis: Prevalence, Strain Characterization And Sequelae, Leslie A. Lafferty

Graduate School of Biomedical Sciences Theses and Dissertations

Aerobic vaginitis (AV) is a more recently defined infection that involves aerobic pathogenic bacteria that replace the normal flora of the vaginal tract. It is commonly mistaken for other vaginal infections, such as bacterial vaginosis (BV), because they share many common symptoms. AV leads to complications during pregnancy, such as premature delivery and amnion infection, and is diagnosed by indications that range from vaginal discharge to inflammation. Because this infection is difficult to diagnose differentially from other vaginal infections, it is important to determine what pathogens are involved in AV so that we may have the ability to detect them. …
