Pyonephrosis is a medical condition characterized by the presence of pus in the kidney. This usually occurs due to an infection that leads to the buildup of pus and can result in severe complications if not treated promptly. Understanding pyonephrosis involves looking at its pathophysiology, causes, symptoms, diagnostics, treatments, and more.
Pathophysiology
1. Structure of the Kidney
The kidney is a vital organ responsible for filtering blood, removing waste, and regulating fluid balance. It consists of:
- Cortex: The outer layer that contains nephrons, the functional units of the kidney.
- Medulla: The inner region where urine is concentrated and transported to the renal pelvis.
- Renal Pelvis: The area where urine collects before moving to the ureter.
2. Blood Supply
The kidneys receive blood from the renal arteries, which branch from the abdominal aorta. Each kidney is supplied by one renal artery that divides into smaller arteries, providing oxygen and nutrients necessary for kidney function.
3. Nerve Supply
The renal nerves, which are part of the autonomic nervous system, control kidney function, including blood flow regulation and urine production.
Types of Pyonephrosis
Pyonephrosis can be classified into two main types:
- Acute Pyonephrosis: Rapid onset, often linked to severe infections that can lead to kidney failure if untreated.
- Chronic Pyonephrosis: A slower progression, often resulting from recurrent urinary tract infections (UTIs) or long-term obstruction.
Causes of Pyonephrosis
Here are 20 potential causes:
