Filter by:Nearly 10% of the Belgian population suffer from kidney stone disease. Recent reviews reported that kidney stones represent an underestimated risk factor for further kidney function deterioration. Preventive measures are recommended in lithiases patients to prevent the formation of new stones. The individual effects of different medicated prosthetic interventions have been documented in clinical trials. However, there is little data on the effectiveness of combining these different preventive measures in routine clinical practice (real-world context). Patients with kidney stone disease require a complete metabolic assessment. The three main factors contributing to the stone's formation are the patient's metabolism, diet and lifestyle. Metabolic work-up is recommended by the American Urology Association to identify and correct the factors responsible for urinary stone formation such as hypercalciuria, hyperoxaluria, hyperuricuria, hypocitraturia or abnormalities of urinary pH. The metabolic work-up includes at minimum the 24h urine test, a blood test and spot urine test. Dietary habits and lifestyle are assessed by means of a questionnaire. The CHU Brugmann Hospital has a specialized multidisciplinary clinic for renal lithiases and mineral metabolism. Preventive personalized and interdisciplinary care in CHU Brugmann consists of a full metabolic work-up allowing the identification of lithogenic risk factors by nephrologists, dietary assessment by specialized dieticians and specific treatment protocol associated with regular follow-up. The aim of this study is to evaluate, in the context of a retrospective single-center cohort study, the effect of preventive personalized and interdisciplinary care on the evolution of all urinary lithogenic risk factors and the recurrence of kidney stones (rate of renal colics, emergency room admissions, and urological interventions).
The purpose of this study is to compare Moses 2.0 pulse modulation technology and the standard high powered Holmium Laser lithotripsy and how it will affect time in the operating room, time using the laser, laser energy, and stone free rates. Currently Moses 2.0 laser technology is FDA approved and currently used in practice since 2021. No study to this date has compared Moses 2.0 without pulse modulation laser technology to Moses 2.0 with pulse modulation laser technology. The study will be including kidney and ureteral stones (a kidney stone located in the tube between the kidney and the bladder) that are 6mm and greater, but less than 20 mm in size undergoing ureteroscopic treatment. High powered lasers are used for "dusting". Dusting is when a laser is used to break a stone down into tiny fragments that are able to pass through the urine.
Rcompare high-energy versus low-energy laser settings in renal stone lithotripsy using low power machines) Holmium YAG 30 watts, examining their respective advantages, limitations, and overall efficacy.
The goal of this clinical trial study is to test if patients with idiopathic calcium oxalate kidney stones have an increased absorption of dietary oxalate, which would lead to increased urinary excretion of oxalate. The study will recruit adult patients with a history of calcium oxalate kidney stones and healthy volunteers without kidney stones. Participants will - ingest fixed diets containing low and moderately high amounts of oxalate for 5 days at a time - ingest a soluble form of oxalate and sugar preparations to test gut permeability - collect urine, blood, stool and breath sample during the fixed diets and the soluble oxalate test
The purpose of the study is to assess procedural completion, the post-operative stone clearance and the safety profile following robotic mini-Percutaneous Nephrolithotomy (PCNL) performed with the MONARCH Platform, Urology.
The goal of this trial is to test if colonization with the gut bacteria Oxalobacter formigenes leads to a reduction in urinary oxalate excretion in patients with calcium oxalate kidney stone disease. The study will recruit adult participants with a history of calcium oxalate kidney stones who are not colonized with Oxalobacter formigenes. Participants will - ingest fixed diets containing low and moderately high amounts of oxalate for 4 days at a time - collect urine, blood and stool samples during the fixed diets - ingest a preparation of live Oxalobacter formigenes to induce colonization with Oxalobacter formigenes
This study investigates if additional basket control in helpful during retrieval of kidney stones especially those that are difficult to reach for standard baskets.
This is a randomized controlled trial which aims to compare the efficacy and safety of Thulium fiber laser (TFL) and holmium:yttrium-aluminum-garnet (Ho:YAG) laser ablation during the treatment of upper urinary tract stone disease with flexible ureteroscopy, demonstrating clinical superiority of TFL.
Limited literature has focused on the use of totally tubeless mini-percutaneous nephrolithotomy (Mini-PCNL) for the treatment of large renal stones. This Randomized Controlled trial aims to compare complication and safety of Mini-PCNL between total tubeless and tubeless Mini-PCNL.
The purpose of this study is to clarify the fundamental processes underlying behavior change, maintenance, and adherence during and after a 3-month fluid intake intervention period.
