These terms "infected hydronephrosis and pionefrosis" indicate different stages of secondary kidney infection in the background of hydronephrosis.
Pionephrosis is a special form of acute and chronic pyelonephritis, associated with obstruction of the ureter with a stone or stricture. The most frequent place of obstruction is the tuberculosis-ureteric anastomosis.
