Renal pelvis obstruction occurs when there’s a blockage in the renal pelvis, the area where urine collects before it flows into the ureter and then to the bladder. This obstruction can lead to kidney damage and a range of complications if not addressed.
Pathophysiology
Structure
- Renal Pelvis: A funnel-shaped structure located at the top of the ureter. It collects urine from the kidneys.
- Kidneys: Organs that filter blood and produce urine.
- Ureter: The tube that carries urine from the kidneys to the bladder.
Blood Supply
- The renal pelvis receives blood from the renal arteries, which branch off from the abdominal aorta. Proper blood flow is essential for kidney function.
Nerve Supply
- The renal pelvis is innervated by nerves from the renal plexus, which helps control the muscles in the area.
Types of Renal Pelvis Obstruction
- Congenital Obstruction: Present at birth.
- Acquired Obstruction: Develops later in life due to various factors.
- Partial Obstruction: Only some urine flow is blocked.
- Complete Obstruction: No urine can pass through.
Causes of Renal Pelvis Obstruction
- Kidney Stones: Hard deposits that form in the kidneys.
- Tumors: Abnormal growths that can press on the renal pelvis.
- Scar Tissue: Can form from previous surgeries or injuries.
- Congenital Abnormalities: Conditions present at birth.
- Infections: Urinary tract infections can lead to inflammation.
