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.
The aim of the present study to perform a full cost analysis for the complete clearance of calyceal stones by retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) for the treatment of lower calyceal stones between 1 and 2 centimeters (cm) in size.
The purpose of this research study is to compare how well two treatments work for removing kidney stones. The two study groups include ureteroscopy with long/short pulse lithotripsy to remove kidney stones. Both of these options are considered standard of care and are used currently in surgery.
Advancements in technology and endourological armamentarium provides multiple surgical options for complicated stone patients. To avoid multiple operations and shorten the total operation durations, bilateral synchronous simultaneous stone surgery (BSSSS) has been popularized in recent years. Our aim is to evaluate the preliminary outcomes of BSSSS in patients undergoing supine percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS).
There are two options for postoperative pain management: opioid and non-opioid analgesia. Pain outcomes will be compared in patients undergoing ureteroscopy and percutaneous nephrolithotomy by randomly administering opioid and non-opioid analgesia.
Background: The exit strategy after ureteroscopy for stone treatment remains a topic for discussion. Current EAU guidelines on urolithiasis state that postoperative stenting is indicated in patients at increased risk of postoperative complications. Stenting is not considered necessary in all other cases, and after uncomplicated procedures. Objective: To analyse the postoperative ureteral stenting strategy in clinical practice looking at the indication, type of stents used and the duration of stenting after ureteroscopy for stone treatment. Furthermore, the investigators will examine in what setting the stents are being removed postoperatively. Study design: This study is a prospective, observational, international, multicentre registry study executed by uCARE. Study population: All patients >18 years with a ureter or renal stone who are planned for ureteroscopic treatment by semi-rigid and/or flexible ureteroscopy are eligible for this study.
Adult patients with kidney stones undergoing surgical intervention with ureteroscopy with laser lithotripsy will be randomized to receive one of two different regimens of oral medications administered prior to induction of general anesthesia. Postoperatively, patients will receive automated daily text messages to assess pain and opioid consumption and subsequently determine which which treatment regimen is superior.
The investigators aimed to evaluate whether these parameters could be guides for us in the selection of RIRS or Mini-PNL procedures in kidney stones that are smaller than 2 cm. The patients that have kidney stones smaller than two cm and be planned to undergo surgery were randomized into 2 groups prospectively. RIRS was performed in the RIRS group using a 7.5-F fiberoptic flexible ureterorenoscope while Mini-PCNL group was dilated up to 16.5F and mini-PCNL was performed with 12F nephroscopy. Preoperative characteristics, operative and postoperative results were compared in two groups. Thereafter, intra and intergroup comparisons were made to determine the effects of HU value, indicating the stone density, higher or less than 677 and the stone location on stone-free rates.
This is a randomized trial to determine the effectiveness of a clinical decision support tool on image ordering for patients with suspected nephrolithiasis. Patients who present with acute unilateral flank or abdominal pain in whom emergency department providers suspect nephrolithiasis will receive either the clinical decision support tool or no tool (usual care).
Percutaneous nephrolithotomy (PCNL) is a minimally- invasive procedure for removing kidney stones. The small incision of PCNL is performed medially from the posterior axillary line according to stones location. Despite the small skin incision patients suffer from postoperative pain due to visceral pain and intercostal nerve injury. The aim of this study is to evaluate the perioperative analgesic effect of subcostal transversus abdominis plane (TAP) block performed prior to PCNL procedure. Primary outcome of our study was Morphine consumption at 48th hour after the surgery. Secondary outcomes were perioperative fentanyl consumption; postoperative Verbal Analog Scale and additional analgesic drug requirement.
