Filter by: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.
In this prospective randomized controlled study, it is aimed to investigate the effects of guidewire advanced through a previously placed double j stent on postoperative complications, operation time and efficacy.
Nephrolithiasis is a disease caused by the formation of kidney stones in the urinary tract which can then partially or completely obstruct the latter causing an extremely sharp pain called renal colic. In industrialized countries, it affects 10 to 20% of the population, and is the most common kidney disease.The primary objective of this study is to identify the clinical, biological, genetic, molecular and environmental determinants predictive of recurrence of renal lithiasis. The study follow-up visit schedule corresponds to the visits usually scheduled as part of patient care: 1 year from the inclusion visit (A1), 3 years (A3) then 5 years (A5). Samples for research (additional volume of blood, urine) will be taken by a registered nurse along with the routine check-up samples.Samples intended for research will be sent by staff to the Biobanque de Picardie (CHU Amiens-Picardie) for processing and conservation.
This study aims to determine the daily rate of endogenous synthesis of oxalate using carbon 13 oxalate isotope tracer technique and a low-oxalate controlled diet.
Objectives: This study aims to determine if the device provides an advantage over traditional free hand puncture by comparing the number of attempts required to obtain access, time to achieve access, radiation exposure to patient and surgeon; and complications.
In this prospective randomised controlled study, investigators aims to evaluate the effect of 80 mg gentamicin added to 3 liters of irrigation fluid on stone free rate, intraoperative and postoperative complications during RIRS for kidney stones.
To obtain postmarket safety and efficacy data on Boston Scientific LithoVue™ Elite System.
The investigators will assess the use of Transcutaneous Neurostimulation (TENS), a pharmacological alternative, for treatment of ureteral stent pain post-ureteroscopy. The primary aim for the investigators is to determine if use of a TENS unit will reduce post-operative pain and nausea associated with the ureteral stent. Secondary aim will be to assess if it can help minimize narcotic use.
