Filter by:This is a double-blind, study to evaluate the performance of NV-VPAC1 PCa Urine Diagnostic Test in three distinct populations being treated at the Intermountain Urology Clinic. The first population (positive control) is comprised of men with biopsy-confirmed PCa who are scheduled for prostatectomy. The second population (negative control) is comprised of men with benign prostatic hypertrophy (BPH) who are scheduled for transurethral resection of the prostate (TURP). The third population (negative control) is comprised of men or women with bladder/kidney stones who are scheduled for a cystoscopy.
This study tests moving kidney stones using focused ultrasound (referred to as ultrasonic propulsion). The study includes multiple population groups to investigate the ability of our technology to: a) move stone fragments to a location within the kidney to improve their chances of passage, and thus reduce the occurrence of additional symptomatic events and retreatment or b) move a symptomatic stone to relieve symptoms and pain.
A total of 20 subjects presenting with urinary stone(s) in the kidney or ureter will be treated with an extracorporeal shockwave lithotripsy device to fragment the stones. Subjects will be followed for 14 days. If at the 14 day follow-up visit the subject continues to present with a stone size 4 mm or greater will have an option of retreatment or other intervention. If the subject consents to be retreated at this time, this subject will be followed up for another 14 days.
Purpose: The purpose of the Stone Centre Serum and Urine Bank is to provide researchers with large numbers of serum and urine samples from kidney stone patients and controls for study of stone disease detection and treatment, and will take into account different genetic backgrounds, ages, and other patient factors to provide a broad sample size for the study of stone disease The Serum and Urine Bank will undoubtedly be an invaluable tool in the quest to understanding urinary stone disease. Objective: The objective of this research is to identify protein species or other compounds responsible for or contributing to kidney stone initiation and propagation.
