Pyonephrosis

Pyonephrosis, also called pus kidney, is a very severe pyogenic renal infection with widespread destruction forming a pus-filled sac and loss of function.

Common Symptoms

Chills; weakness; vomiting; night sweats; low fever; weight loss

Causes

Most common is obstruction from upper urinary stones with secondary infection; next is infected hydronephrosis from renal/ureteral malformation; it may also follow pyelonephritis. E. coli is commonest. When an obstructed hydronephrotic kidney becomes infected and purulent, pus collects; acute pyelonephritis plus acute obstruction causes sudden fever, chills and flank pain, often rapidly progressing to sepsis; without timely treatment the kidney is destroyed.

Treatment

Drainage, surgery, antibiotics

Prevention

Treat urinary stones and obstruction promptly to prevent infection and pyonephrosis.
