A stone located in the portion of the ureter within the bladder is likely to cause what symptoms?

When a stone is located where the ureter enters the bladder, it can obstruct the ureter or irritate the bladder wall. This typically leads to urinary symptoms such as increased frequency of urination, urgency (a sudden, strong need to urinate), and dysuria (painful urination). These symptoms arise due to the bladder's irritation from the stone as it attempts to pass or settle in that area.

Increased thirst and fatigue are more associated with systemic conditions or other types of urinary stones but are not specific indicators of a stone in this anatomical location. Nausea and vomiting are usually symptoms that arise from renal colic or obstruction higher up in the urinary tract, rather than in the bladder itself. Similarly, back pain and fever may suggest complications from a kidney infection or pyelonephritis that can occur due to obstruction higher in the urinary tract, rather than a stone in the bladder area specifically. Thus, the cluster of urinary symptoms described is characteristic of a stone impacting the bladder's normal function.
