What does right kidney mild hydrops mean

Mild hydronephrosis is a swelling of the right kidney, which is the organ of the urinary system that produces urine. Each kidney has two functions: one is to filter blood and remove waste and excess salt and water; the other is to collect urine. The part that collects urine when hydronephrosis occurs is called the renal pelvis, which accumulates excess urine and swells. This is when hydronephrosis occurs. The main cause of hydronephrosis is the obstruction of the urinary system, resulting in the expansion of the renal pelvis and renal calyces. Because the accumulation of urine in the kidney, the increase in pressure makes the renal pelvis and renal calyces expand and the atrophy of renal parenchyma.
