Minimally invasive treatment of multiple stones of the diverticulum of the calyx of the right kidney

A clinical case of a combination of urolithiasis with an abnormal development of the kidney in a 25-year-old patient is described. Computed tomography revealed a diverticulum of the middle calyx of the right kidney and a non-uniform stone 15ґ20 mm in size located in it. Multiple small stones of the middle calyx of the right kidney were visualized with the help of percutaneous mini-nephroscopy. When performing the manipulation, 40 small stones were removed from the diverticulum. After 3 months, at the control examination, no stones were found in the diverticulum of the calyx of the kidney, almost complete regression of retention changes was determined.
