The kidneys are vital organs responsible for filtering waste products from the blood and producing urine. Each kidney contains several structures, including the renal pelvis, major calyces, minor calyces, and nephrons.
These are small, cup-like structures within the kidney that collect urine produced by the nephrons. Multiple minor calyces drain into larger major calyces, which then funnel urine into the renal pelvis before it moves to the bladder.
Minor calyx disorders refer to any abnormal conditions or diseases that affect the minor calyces in the kidneys. These disorders can disrupt the normal flow of urine, cause pain, lead to infections, or impair kidney function.
Common minor calyx disorders include:
- Calyceal Diverticula: Pouches that form in the minor calyces.
- Calyceal Fistulas: Abnormal connections between the minor calyx and other structures.
- Calyceal Stones: Kidney stones that form or get lodged in the minor calyces.
- Calyceal Strictures: Narrowing of the minor calyces, impeding urine flow.
Pathophysiology
Structure
Understanding the structure of the minor calyx helps in comprehending how disorders affect them.
- Minor Calyx Structure: Each kidney has multiple minor calyces (typically 8-18 per kidney) that receive urine from the renal papillae. These minor calyces merge to form major calyces, which then drain into the renal pelvis.
Blood Supply
- Blood Vessels: The minor calyces receive blood through the renal arteries, which branch into smaller arterioles supplying the renal cortex and medulla. Proper blood flow is crucial for kidney function and the health of the calyces.
Nerve Supply
- Nervous System: The kidneys are innervated by sympathetic nerves that regulate blood flow and urine production. Sensory nerves in the minor calyces can transmit pain signals when disorders cause irritation or obstruction.
Types of Minor Calyx Disorders
- Calyceal Diverticula
- Calyceal Fistulas
- Calyceal Stones
- Calyceal Strictures
- Calyceal Hematomas
- Calyceal Infections (Pyelitis)
- Calyceal Tumors
- Calyceal Obstructions
- Calyceal Cysts
- Calyceal Inflammation
