Abstract
The calyx diverticulum is a cavity lined with urothelium that communicates through a narrow canal with the renal calyx-pelvis system. Most calyx diverticula are 0.5 to 2.0 cm in diameter and require surgical treatment exclusively for clinical manifestations of associated diseases. The most common complications of this nosology include urolithiasis and recurrent urinary tract infections. This article presents a rare case of a large diverticulum of the middle group of the calyces of the left kidney. The dimensions of the cavity filled with urine were 10 cm, which resulted in recurrent pyelonephritis, paranephritis and urosepsis.
