Urologic Surgery Trials

For enrollment information involving the following trials, please contact one of the research staff members on the "Meet the Team" page.

Endoscopic Visualization & Outcomes (WATER vs. SALINE)

Perioperative Physical Activity (PEDOMETER)

Frailty Study

Tissue Bank


The effects of water versus saline on absorption rates and visualization during ureteroscopy.


• Adult patients meeting medical requirements to undergo ureteroscopy (diagnostic and/or treatment)
• Patient must be consentable or have a legal representative sign the ICF

Exclusion Criteria:

• None


The purpose of this study is to determine if the use of water or saline during ureteroscopy—a procedure where a small ureteroscope is used to guide through the ureter and renal (kidney) collecting system—has any clinical implications such as improved visualization, decreased operative time, and improved patient outcomes.

Principal Investigators: Dr. Kenneth Ogan, Dr. John Pattaras


Prospective randomized study of exercise in patients undergoing urologic surgery.


• Adult patients scheduled for operative procedure with an inpatient postoperative stay
• Willing and able to give blood samples, complete a questionnaire, and fill out the step log

Exclusion Criteria:

• None


Patients are given a pedometer and asked to record their daily steps in a log. The purpose of this study is to determine if we are able to increase patients’ physical activity in the perioperative period with the aide of pedometers.

Principal Investigators: Dr. Kenneth Ogan, Dr. Viraj Master, Dr. John Pattaras, Dr. Peter Nieh


This study investigates frailty as a predictor of outcomes in patients undergoing major surgical procedures. The purpose of this study is to understand and qualify the impact of frailty as a pre-operative risk criteria. This information would assist both surgeons and patients in optimizing management decisions in the future.


• Patients scheduled to undergo major surgical procedures (urologic, colorectal, intra-abdominal and/or vascular)
• Patients willing to do the study preoperative assessment tools

Exclusion Criteria:

• Cognitive disorders (dementia, CVA, etc.)
• Neurologic disorder with functional motor disorder (Parkinson's disease, multiple sclerosis, stroke, etc.)
• Depression treated with antidepressant medications
• Patients taking Carbidopa, Levodoa or Donepezil

Principal InvestigatorS: Dr. Kenneth Ogan, Dr. Viraj Master

Co-Investigators & Collaborators: Dr. John Pattaras, Dr. Peter Nieh, and four surgeons from the Department of Surgery: Dr. John Sweeney, Dr. David Kooby, Dr. Shishir Maithel, Dr. Shipra Arya


Urological tissue and specimen bank at Emory University and affiliated medical centers.


The study is open to all male and female patients undergoing evaluation for surgical treatment/removal of urologic organs and tissue. This includes:

• Men: kidneys, bladder, prostate, seminal vesicles, and lymph nodes
• Women: kidneys, bladder, uterus, ovaries, vaginal tissue, fallopian tubes and lymph nodes

Eligible Treatment Centers:

• Emory University Hospital
• The Emory Clinic
• Emory Saint Joseph's Hospital
• Emory Midtown Hospital
• Grady Memorial Hospital

Exclusion Criteria

• None

Other Information:

• Following surgical removal of the urologic organ, all tissue will be processed by the pathology department for routine standard histopathological examination. For the specimen bank, a small portion of the tissue will be used for research testing.
• Additional specimens such as blood, urine, and saliva may be collected for research purposes.
• Patient medical records and test results will be reviewed and compiled in a relational database for research analysis.

Principal Investigator: Dr. John Petros

Co-Investigators & Collaborators: Dr. Martin Sanda, Dr. Viraj Master, Dr. Adeboye Osunkoya (Department of Pathology and Laboratory Medicine), Dr. Joseph Shelton (Department of Radiation Oncology)
