Filter by:Several studies evaluated the benefit of a short-term external ureteral catheter (UC) compared to double-J (DJ) ureteral stent after flexible ureteroscopy (URS); the results were controversial. These studies had combined analyses of ureteral and renal stones with a high risk of selection bias. Studies comparing external UC and DJ stent after flexible URS for isolated renal stones are lacking. In the present study, the investigators will compare the outcomes of using a one-day external UC versus a DJ internal ureteral stent for ureteral drainage after retrograde flexible URS (retrograde intrarenal surgery "RIRS") for renal stones. The investigators aim to identify the best ureteral drainage method after RIRS regarding stone clearance, complications, and stent-related symptoms.
The goal of this clinical trial is to test the Break Wave™ system in patients with upper urinary tract stones. The main question it aims to answer is whether the device is safe and effective in fragmenting (breaking) stones. Participants will a) undergo the Break Wave™ procedure, b) have a telehealth visit at 2 weeks, and c) return for an imaging study at approximately 10 weeks post-procedure.
This research study is to determine how well the Erector Spinae Plane Block (ESPB) works for kidney stone pain and any possible side effects.
This study aims to compare the efficacy and safety of both types of lasers, Holmium MOSES and TFL, in management of kidney stones requiring treatment.
This is a prospective controlled study to compare the efficacy and safety of two methods of flexible urethroscopy in patients with urolithiasis, as well as the effect of surgery on quality of life.
To define the effect of crystal light, potassium citrate, or both on urinary stone risk factors in patients with a history of stone and hypocitraturia/low pH
perform a comparative randomized trial comparing the efficacy and safety of percutaneous nephrolithotomy (PCNL) in the prone and modified supine positions in management of complex renal stones
This study aims to learn more about how oxalate, a compound found in many foods, may affect a person's chances of forming kidney stones. Active participation in this study will last for around one week. For the first two days, subjects will be asked to eat a special diet at home. From Days 3-5, they will eat special meals delivered to their home from a research clinic at the University of Chicago. They will also collect 24-hour urine samples at home on Days 4 and 5. On Day 6, they will come in to the research clinic at the University of Chicago in Hyde Park, where they will spend most of the day. They will receive a special liquid that contains oxalate, and we will have them eat a specially prepared breakfast that is low in oxalate and citrate.
The purpose of this study is to implement and assess a standard way of prescribing opioid pain medication following PCNL (a kidney stone removal surgery) to ensure patients are being discharged with an appropriate quantity of pain management medication.
This is a single-center study that aims to earn more about how two different compounds found in food, oxalate and citrate, may affect a person's chances of forming kidney stones.
