Calyceal Diseases

Pathophysiology

1. Structure of the Calyces:

• The calyces are part of the kidney’s drainage system. Each kidney has several minor calyces that converge to form major calyces, which then lead to the renal pelvis.

2. Blood Supply:

• The blood supply to the calyces comes from the renal arteries, which branch into smaller arteries that ensure adequate oxygen and nutrients reach the kidney tissues.

3. Nerve Supply:

• The renal nerves, which are part of the autonomic nervous system, control the function of the kidneys, including the calyces.

Types of Calyceal Diseases

1. Calyceal Calculi (Kidney Stones)
2. Calyceal Cysts
3. Calyceal Infections (Pyelonephritis)
4. Calyceal Obstruction
5. Calyceal Tumors (Benign or Malignant)
6. Calyceal Hypoplasia
7. Calyceal Dilation
8. Congenital Anomalies of the Calyces
