Calyceal Obstruction

Understanding calyceal obstruction is vital for recognizing its symptoms, identifying its causes, and seeking appropriate treatment to maintain kidney health.

Pathophysiology

Structure of the Kidneys

The kidneys are bean-shaped organs located on either side of the spine. Each kidney contains calyces, which funnel urine into the renal pelvis before it moves to the bladder.

Blood Supply to the Kidneys

The kidneys receive blood from the renal arteries, which branch off the abdominal aorta. This blood supply is essential for filtering waste and producing urine.

Nerve Supply to the Kidneys

The kidneys are supplied by nerves from the autonomic nervous system, which regulates kidney function and blood flow.

Types of Calyceal Obstruction

Primary Obstruction

Primary obstruction occurs due to structural issues within the kidney, such as congenital malformations.

Secondary Obstruction

Secondary obstruction is caused by external factors, such as tumors or kidney stones that compress the calyces.

Causes of Calyceal Obstruction

1. Kidney Stones: Hard deposits of minerals that form in the kidneys.
2. Tumors: Abnormal growths that can block urine flow.
3. Congenital Anomalies: Structural problems present at birth.
