hydronephrosis
Học thuậtThân thiện
Definition
- Noun:
- A medical condition characterized by the swelling of a kidney due to a buildup of urine: This occurs because urine cannot drain properly from the kidney to the bladder, typically due to a blockage in the ureter (the tube that carries urine from the kidney to the bladder).
Usage
- As a medical diagnosis: The term is used to describe the specific pathological state of the kidney.
- The ultrasound revealed hydronephrosis in the patient's left kidney.
- Chronic hydronephrosis can lead to kidney damage if left untreated.
Advanced Usage
"Bilateral hydronephrosis": A condition where both kidneys are swollen due to urine accumulation, often indicating a more systemic obstruction.
- The newborn was diagnosed with bilateral hydronephrosis, requiring immediate evaluation.
"Obstructive hydronephrosis": Specifies that the swelling is directly caused by a physical blockage.
- The stone caused obstructive hydronephrosis, which was very painful.

Notes
- Hydronephrosis is not an idiom or a phrase with figurative meaning. It is a precise clinical term used in urology and nephrology.
- The condition itself is a sign of an underlying problem (like a kidney stone, tumor, or congenital defect) rather than a primary disease.
Noun
- accumulation of urine in the kidney because of an obstruction in the ureter
