the obstruction progresses, more proximal structures like the renal collecting system (renal pelvis and calyces) becomes dilated, termed hydronephrosis.
What is the term for dilation expansion of the ureter?
Analogously, hydroureter is defined as a dilation of the ureter. The presence of hydronephrosis or hydroureter can be physiologic or pathologic. It may be acute or chronic, unilateral or bilateral. It can be secondary to obstruction of the urinary tract, but it can also be present even without obstruction
What is an obstruction of the urethra called?
Obstructive uropathy is when your urine can't flow (either partially or completely) through your ureter, bladder, or urethra due to some type of obstruction. Instead of flowing from your kidneys to your bladder, urine flows backward, or refluxes, into your kidneys.
