Pain from calculus at the ureterovesical junction typically radiates to which area?

Pain from a calculus at the ureterovesical junction typically radiates to the groin due to the nature of the nerve pathways involved and the anatomical locations. The ureterovesical junction, where the ureter connects to the bladder, is innervated by visceral nerves that traverse through the lower abdomen and into the groin.

When a calculus obstructs this junction, it causes intense pain that is often referred to the areas supplied by these nerves. This means that the pain can extend from the lower abdomen down to the groin, particularly on the side affected by the stone. The characteristic pattern of pain radiating to the groin is a classic symptom of renal colic caused by ureteral stones.

While other options describe areas where pain might be felt due to different conditions or types of pain, the specific referral pattern in the case of a calculus at the ureterovesical junction is best identified as radiating to the groin.
