Answer: False
Explanation:
Ureterectasis refers to the distention or dilation of the ureter, not the urethra. It is often caused by a blockage, such as a kidney stone or a congenital abnormality, leading to the buildup of urine in the ureter, also known as hydroureter. The urethra is a different part of the urinary system, and its distention would be referred to as urethrectasis or urethral dilation.
