What condition would be indicated by a urinalysis for symptoms of renal colic?

The presence of kidney stones, or nephrolithiasis, is directly associated with renal colic, which is characterized by severe pain in the flank and lower abdomen. A urinalysis in patients experiencing renal colic often reveals hematuria (blood in the urine), crystals, or signs of obstruction due to stones. These findings can help in confirming the diagnosis of kidney stones.

Other conditions listed do not specifically align with symptoms associated with renal colic. For example, an ectopic pregnancy typically presents with pelvic pain and may show signs of internal bleeding, but it would not characteristically lead to the findings expected on a urinalysis for renal colic. Similarly, pancreatitis generally causes abdominal pain, but this pain is related to the pancreas and does not align with urinary findings. A urinary tract infection (UTI) can also present with abdominal pain and might show abnormalities on urinalysis, but the pain associated with a UTI is more often related to bladder irritation than the significant flank pain characteristic of renal colic due to kidney stones.

Thus, based on the presentation of renal colic and the expected urinalysis findings, kidney stones are the condition most accurately indicated.
