Brief Summary:

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.
