The study of individual anatomical variations of the urinary tract is an important aspect in planning of surgical treatment for urolithiasis. Multislice computed tomography (MSCT) is used as the standard imaging technique for nephrolithiasis, allowing determining the morphometric parameters of the renal collecting system, the characteristics of stones and their spatial relationships at the preoperative stage. However, there is a lack of systematic information in the literature regarding the impact of structural variations in the renal cavity based on MSCT data on the success of minimally invasive procedures for nephrolithiasis treatment. Currently, there is no widely accepted standardized anatomical or radiological classification system for the calyceal-pelvic complex. This review discusses various types of renal cavity systems, demonstrates the impact of their anatomical parameters on the success of minimally invasive treatments and a reduction in the risk of complications.
Keywords: urolithiasis, MSCT of the kidneys, anatomy of the pelvicalyceal system, minimally invasive stone treatments, extracorporeal shock wave lithotripsy, percutaneous nephrolithotomy, retrograde intrarenal surgery.
