Why is urinary obstruction at the urethra more dangerous than at the ureter?
What will be an ideal response?
Urinary obstruction at the urethra is more dangerous than urinary obstruction in the ureter because urine would be prevented from exiting the body and would build up in the urinary bladder, leading to rupture of the urinary bladder. Obstruction of a ureter would interfere with the flow of urine between the kidney and the urinary bladder. Obstruction of only one of the two ureters is less hazardous than obstruction of two urethrae because the kidney could still excrete wastes that could be voided.
