Major Calyx Infection

The major calyces are cup-shaped structures in the kidneys that collect urine from the renal? papillae (tips of the renal pyramids) and channel it into the renal pelvis, which then drains into the ureter and bladder. Each kidney typically has two or three major calyces.

A Major Calyx Infection? occurs when bacteria invade the major calyces, leading to infection?, or irritation, often causing pain?, swelling?, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation? and infection. This condition is a type of urinary tract infection (UTI) that can ascend from the lower urinary tract or spread from the bloodstream. If untreated, it can escalate to more severe kidney infections or sepsis.

Pathophysiology

Structure

• Kidney Anatomy: Each kidney consists of an outer cortex and an inner medulla containing the renal? pyramids. The tips of these pyramids, called papillae, empty urine into minor calyces.
• Calyces: Minor calyces merge to form major calyces, which drain into the renal? pelvis and then into the ureters.

Blood Supply

• Renal? Arteries: Supply oxygenated blood to the kidneys.
• Peritubular Capillaries: Surround the nephron tubules, facilitating exchange between blood and urine.
• Vasa Recta: Specialized capillaries in the medulla that help maintain the kidney’s concentration gradient.

Nerve Supply

• Sympathetic Nerves: Control blood flow and filtration rate.
• Parasympathetic Nerves: Play a minimal role in kidney function.
• Sensory Nerves: Detect pain? and other sensations from the kidneys.
