Renal Crest Obstruction

Pathophysiology

Structure of the Kidneys?

The kidneys are bean-shaped organs located on either side of the spine. They filter blood to remove waste, balance fluids, and regulate electrolytes. The renal crest is part of the renal pelvis?, which is the area where urine collects before moving to the ureter?.

Blood Supply

The kidneys receive blood from the renal arteries?, which branch off from the abdominal aorta?. This rich blood supply is essential for filtering waste and maintaining the body’s fluid balance.

Nerve Supply

The kidneys are innervated by the autonomic nervous system, which regulates involuntary bodily functions. This nerve supply helps control kidney functions such as blood flow and urine formation.

Types of Renal Crest Obstruction

1. Partial Obstruction: Some urine can still pass, but at a reduced rate.
2. Complete Obstruction: No urine can pass, leading to severe? complications.
3. Unilateral? Obstruction: Affects one kidney.
4. Bilateral? Obstruction: Affects both kidneys.

Causes of Renal Crest Obstruction
