The nurse is aware that there are three areas of the ureters that have a propensity for obstruction. Prompt management of renal calculi is most important when the stone is located in this area of the ureter:
A) Ureteropelvic junction
B) Ureteral segment near the sacroiliac junction
C) Ureterovesical junction
D) Urethra
Ans: A
Feedback: There are three narrowed areas of each ureter: the ureteropelvic junction, the ureteral segment near the sacroiliac junction, and the ureterovesical junction. These three areas of the ureters have a propensity for obstruction by renal calculi or stricture. Obstruction of the ureteropelvic junction is the most serious because of its close proximity to the kidney and the risk of associated kidney dysfunction.
