An observational study in Urolithiasis, Stone, Kidney and Stone Ureter, sponsored by Marmara University. Enrolling by invitation at 1 site in Turkey (Türkiye). Per ClinicalTrials.gov, last updated 2025-08-20.
Sponsored by Marmara University · Observational
The purpose of this registry is to collect data on patients who have undergone minimally invasive treatments for urinary system stone disease, including percutaneous nephrolithotomy (PCNL), shock wave lithotripsy (SWL), semi-rigid ureterorenoscopy (URS), and flexible ureterorenoscopy (F-URS).
In this project, the Minimally Invasive Urology Association urolithiasis study group aimed to collect the data of adult and pediatric urinary system stone patients treated with PCNL, SWL, URS, and F-URS in a non-randomized, observational, and prospective manner. The registry was to be conducted multi-center in Turkey.
In this project, Excel files were created and shared via Google Drive with the responsible physicians at the centers to be included in the study. Each parameter was prepared in an explanatory manner and can be readily filled out by physicians familiar with these methods. The ability to examine and modify existing data will be restricted to the worker and the database administrator. Patients' identities will not be revealed in the registry.
The collected data are summarized in three sections under the major headings below;
A separate application to the ethics committee will be submitted for each study on the subject that will be created in the future from the multi-center, prospectively recorded data pool and on the subject that will be investigated.
509 studies on the registry are indexed under Kidney Calculi; 146 are open to participants now.
This study's planned enrollment of 10,000 is above the median of 160 across 96 observational studies indexed under Kidney Calculi.
