How long can ureteral calculi enter the bladder at the third stricture

There is no precise clinical indication of how long it takes for a ureteral stone to enter the bladder at the third stricture, which can take days, months, or longer.

The third stricture is usually at the end of the ureter, where the ureter enters the bladder wall. If the stone is small and the ureter is unobstructed, the stone can pass smoothly through the ureter, and it can usually enter the bladder in days. If the stone is large or there is a stricture or obstruction in the ureter, the stone may not pass smoothly through the ureter into the bladder, and it may take months or longer to enter the bladder through the ureter.
