What is the meaning expanded renal pelvis?

Answer 1

An expanded renal pelvis refers to an enlargement of the renal pelvis, which is the funnel-shaped structure in the kidney that collects urine before it moves to the ureter. This condition can be caused by various factors, including obstruction of urine flow, kidney stones, or congenital abnormalities. An expanded renal pelvis can lead to hydronephrosis, where fluid accumulates in the kidney, potentially causing damage if left untreated. Diagnosis is typically made through imaging studies like ultrasound or CT scans.
