What does pyonephrosis mean?

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.

What are the differences between infected hydronephrosis and pyonephrosis?

Pyonephrosis is a suppurative infection of the upper urinary system which differs from infected hydronephrosis by the presence of frank pus. It is usually associated with parenchymal damage, chronic pyelonephritis and subsequent loss of kidney function [1].

How is pyonephrosis diagnosed?

The diagnosis of pyonephrosis is suspected when the clinical symptoms of fever and flank pain are combined with the radiologic evidence of obstruction to the urinary tract. Sonography gives a prompt diagnosis of hydronephrosis, and needle puncture of the kidney yields pus and establishes the presence of pyonephrosis.

What causes Hydroureter?

Hydroureter refers to dilation of the ureter(s) and is most often caused by obstruction of urine outflow due to blockage of the ureter(s) by calculi, chronic inflammation, luminal or intramural neoplasia, or accidental ligation during surgery.

Which condition is the abnormal enlargement of a ureter?

This distal enlargement of the ureter within the bladder is called a ureterocele. See a case history of ureterocele.

Is Pyonephrosis the same as pyelonephritis?

Pyonephrosis is characterized by accumulation of purulent debris and sediment in the renal pelvis and urinary collecting system. Children with pyonephrosis have symptoms similar to acute pyelonephritis but have additional structural obstructive hydronephrosis.

What causes pus in kidneys?

A renal abscess, also known as a perirenal or kidney abscess, is a pocket of pus that develops in the kidney tissue. It results from the migration of bacteria from another infection site on the body to the kidneys.

What is Hydroureter of kidney?

Hydronephrosis is defined as dilatation and distension of the renal collecting system of one or both kidneys due to obstruction of urine outflow distal to the renal pelvis (i.e., ureter, urinary bladder, and urethra). Dilation of the ureter due to obstruction of urine outflow is called hydroureter.

What kind of health care does urology do?

Urology is a part of health care that deals with diseases of the male and female urinary tract (kidneys, ureters, bladder and urethra). It also deals with the male organs that are able to make babies (penis, testes, scrotum, prostate, etc.).

How big is the scope of Urology in the US?

The scope of urology is big and the American Urological Association has named seven subspecialty parts: Who takes care of urology patients? If you have a problem with urologic health you might see a urologist.

What is the function of the bladder in the human body?

The bladder is a hollow organ in the pelvis with flexible, muscular walls. Its main function is to store urine before it leaves the body. Urine is made by the kidneys and is then carried to the bladder through tubes called ureters. When you urinate, the muscles in the bladder contract, and urine is forced out…
