Detailed explanation-1: -Hydronephrosis is defined as dilatation and distension of the renal collecting system of one or both kidneys due to obstruction of urine outflow distal to the renal pelvis (i.e., ureter, urinary bladder, and urethra). Dilation of the ureter due to obstruction of urine outflow is called hydroureter.
Detailed explanation-2: -Renal pelvic dilation refers to excessive dilation of the fetal intrarenal collecting system. Although a different terminology is used, pelviectasis or pyelectasis most often refers to mild dilation, and hydronephrosis is reserved for severe cases that are more likely to be clinically significant.
Detailed explanation-3: -Hydronephrosis, also known as urinary tract dilation, is when the area of the kidney where urine is collected is enlarged, or dilated. It can range from mild to severe, depending on the cause of the dilation.
Detailed explanation-4: -Hydronephrosis occurs when there is either a blockage of the outflow of urine, or reverse flow of urine already in the bladder (called reflux) that can cause the renal pelvis to become enlarged.
