Filter by:This is a randomized controlled clinical study evaluating the use of next-generation sequencing (NGS) to improve antibiotic prescribing before ureteroscopy or percutaneous nephrolithotomy.
Obstructing urolithiasis can be life-threatening in the setting of urinary tract infection. The purpose of this study is to identify and validate risk factors and markers for the presence of infection and development of sepsis among patients with obstructing urolithiasis.
The goals of this study are to improve the ability of pediatric patients and their caregivers to select surgical treatment options for kidney stones and to enable urologists to use techniques that result in the best outcomes for these surgeries.
Within the CHU Brugmann hospital, a multidisciplinary Renal Lithiasis and Mineral Metabolism clinic has been inaugurated in 2017. During the first months of 2018, the activities of the clinic have been focalized on the pre-analytical and analytical aspects of metabolic work-up. 15 patients are followed on average per week. The clinic is recognized as one of the 24 core centers of the European Nephrolithiasis Network and it is the only clinic included in this network in Belgium. The actual practice of the clinic has been published in a survey regarding current practice patterns of stone centers across Europe. Following this publication, the members of the board of the European Nephrolithiasis Network have put as common effort to standardize the care of kidney stone formers and obtained endorsement to perform a second survey in each core center. The aim of this initiative is to share information from real patients in aggregate form. Each core center practice will be evaluated by the second survey by an analysis of the robustness of clinical, biological, urological and radiological data. The main aim of this project consists in the constitution of a clinical, biological, urological and radiological database of followed patients. This database could be shared in aggregate form by using a specialized coding system for the patients. The database will enable the investigators to: - describe the epidemiological and clinico-biological characteristics of the CHU Brugmann patient population - gather information about the kidney function outcome - analyze and classify identified prolithogenics factors - characterize related metabolic disorders (diabetes mellitus, metabolic syndrome, arterial hypertension, chronic kidney diseases, osteoporosis...) - identify the patients that could participate in the international trials on kidney stone disease - identify the patients that will need a specialized genetic testing. - evaluate the impact of the clinic activity and metabolic work-up on the rate of recurrence of kidney stones in the patient population. The obtained data will be compared with the global data from the European Nephrolithiasis Network.
Randomized treatment trial of baking soda or LithoLyte to determine if baking soda and Litholyte are effective in raising 24 hour urine citrate and pH.
A comparison on the outcomes of patients undergoing shockwave lithotripsy using the Storz machine versus the Dornier machine.
Patients undergoing retrograde intrarenal surgery for kidney stones from November 2017 to May 2018 were prospectively recruited to participate in the study. In each case after the beginning of general anesthesia with mechanical ventilation surgeons were asked to assess the mobility of the operative field and conditions for laser lithotripsy according to the developed questionnaire scale. The questionnaire consisted of 5 degrees of assessment of kidney mobility and each question was scored from 1 to 5, 1 being very mobile (extremely poor conditions for dusting) and 5 completely immobile (Ideal conditions for dusting). After this assessment modified technique of general anesthesia was applied called combined respiratory support which consisted of reduction of tidal volume to 250-300 ml and respiratory rate to 4-5 per minute with transcatheter high frequency jet ventilation through endotracheal tube with a respiratory cycle frequency of 300 per minute and maintained during retrograde intrarenal surgery. At the beginning of combined respiratory approach, surgeons were once again asked to assess the mobility of the operative field and the conditions for laser lithotripsy. Main ventilation parameters were recorded and compared in both regimens.
The purpose of this research study is to compare how well two medications work to control post-operative pain.
Pain associated with renal stone disease is typically caused by an obstructing stone that obstructs the flow of urine, which results in renal collecting system dilatation. Non-obstructing renal calculi that do not cause renal collecting system dilatation are thought to be painless. The objective of this study is to prospectively determine if the removal of non-obstructing renal calculi can reduce or eliminate participant's pain and/or improve their quality of life.
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.
