pyel

Pyel refers to the renal pelvis, which is the funnel-shaped structure that collects urine from the nephrons in the kidney and channels it into the ureter. It is an essential part of the urinary system, acting as a conduit for urine flow. The renal pelvis is located within the hilum of the kidney, the indented area where blood vessels and nerves also enter and exit. Its inner lining is composed of transitional epithelium, which can expand to accommodate the flow of urine.

Diseases or conditions affecting the pyel can disrupt normal kidney function. Pyelonephritis, for instance, is a serious infection that often begins in the lower urinary tract and ascends to involve the renal pelvis and kidney tissue itself. Inflammation of the renal pelvis can also occur due to kidney stones that obstruct the flow of urine, leading to pain and potential kidney damage. Medical imaging techniques such as ultrasound, CT scans, and intravenous pyelography are commonly used to visualize the pyel and diagnose related abnormalities. Treatment for pyel-related issues varies depending on the underlying cause and may include antibiotics for infection, surgical intervention for stones, or other therapies to restore proper urine drainage.
