Calyceal Disorders

Calyceal disorders refer to problems affecting the calyces of the kidneys, which are small cup-like structures that collect urine from the kidney’s collecting ducts. Understanding these disorders is crucial for maintaining kidney health.

Pathophysiology

Structure

• Calyces: The kidney has several calyces (major and minor) that funnel urine into the renal pelvis, leading to the ureter.

Blood Supply

• Renal Arteries: These arteries supply blood to the kidneys, branching off the abdominal aorta.

Nerve Supply

• Autonomic Nervous System: The kidneys receive nerve signals from the sympathetic and parasympathetic nervous systems, regulating kidney function.

Types of Calyceal Disorders

1. Calyceal Stones: Hard deposits formed in the calyces.
2. Calyceal Obstruction: Blockage preventing urine flow.
3. Calyceal Infection: Infections affecting the calyces.
4. Calyceal Tumors: Abnormal growths in the calyces.
5. Calyceal Cysts: Fluid-filled sacs in the calyces.
6. Hydronephrosis: Swelling of the kidney due to urine buildup.
7. Calyceal Rupture: Tear in the calyx.
8. Congenital Anomalies: Birth defects affecting calyceal structure.
9. Calyceal Diverticulum: Outpouching of the calyx.
10. Calyceal Papillary Necrosis: Death of tissue in the calyx.

Diagnostic Tests

1. Urinalysis: Examining urine for signs of infection or stones.
2. Blood tests: Checking kidney function and electrolytes.

11. Retrograde pyelography: Imaging using contrast dye.
12. 24-hour urine collection: Analyzing urine composition.
13. Intravenous pyelogram (IVP): Imaging with contrast.
14. Kidney scan: Assessing blood flow to kidneys.
15. Serum creatinine: Measuring kidney function.
16. Electrolyte panel: Checking mineral levels.
17. pH test: Analyzing urine acidity.
18. Glomerular filtration rate (GFR): Estimating kidney function.
19. Cultures: Testing for bacteria or infections.
20. Imaging-guided biopsy: Targeting abnormal areas for testing.

Non-Pharmacological Treatments
