Hydronephrosis is the swelling of one or both kidneys due to a build-up of urine caused by a blockage or obstruction preventing urine from draining normally from the kidney to the bladder. Pyonephrosis occurs when hydronephrosis is further complicated by a kidney infection, resulting in pus collecting in the swollen kidney. Treatment options for hydronephrosis include minimally invasive procedures like percutaneous nephrostomy tubes, ureteral stents, and nephrolithotripsy, as well as open surgical operations to bypass or remove the obstruction.

8. Hydronephrosis
•Hydronephrosis is the swelling of a
kidney due to a build-up of urine.
• It happens when urine cannot drain out from the
kidney to the bladder from a blockage or
obstruction. Hydronephrosis can occur in one or
both kidneys. The main function of the urinary tract
is to remove wastes and fluid from the body.

11. Pyonephrosis
• pus in the renal pelvis—results from urinary tract
obstruction in the presence of pyelonephritis.
• Purulent exudate (inflammatory cells, infectious
organisms, and necrotic, sloughed urothelium)
collects in the hydronephrotic collecting system
("pus under pressure") and forms an abscess.
