Left hydronephrosis with ureteral dilatation how to return a responsibility

Left hydronephrosis with ureteral dilatation may be caused by urinary calculi, tuberculosis, kidney cancer and other reasons.

1. Urinary

calculi may block the urethra, causing urethral obstruction, causing urine to remain in the kidney causing left hydronephrosis, and urine will accumulate in a certain segment of the ureter, causing ureteral dilatation.

2. Tuberculosis

may cause ureteral stricture, causing urine to accumulate in a certain segment of the ureter, causing ureteral dilatation, and may continue upward, causing left hydronephrosis to form.

3. Renal

cancer may oppress the urethra, causing obstruction, causing some urine to flow back to the left kidney, forming left hydronephrosis, and some urine to accumulate in the ureter, so it will be accompanied by ureteral dilatation.
