Abstract

Objective: To determine the role of urinalysis in patients undergoing CT KUB (kidney, ureter, bladder) for acute renal pain.
Study Design: Descriptive cross sectional validation study.
Place and Duration of Study: Study was conducted at PAF hospital Islamabad, from Aug 2014 to Sep 2015.
Material and Methods: A total of 93 patients coming to the radiology department of Pakistan Air Force (PAF) hospital for assessment of acute flank pain underwent CT KUB (Kidneys, ureter and bladder) and urine routine examination (RE). Urinalysis was considered abnormal if it contained pus cells greater than five per high field or red blood cells, or both. Result of CT KUB was compared with urinalysis to find out if the latter could be used to predict presence or absence of urolithiasis. Frequency of abnormal urinalysis was calculated for site and size of
calculus detected on CT KUB for selection for CT while those with normal urinalysis could be evaluated by ultrasound only.
Results: Urinalysis was identified as an invalid indicator for renal tract calculi in patients with acute flank pain. Abnormal Urine RE was mostly associated with lower tract urinary calculi and with smaller calculi than larger ones.
Conclusion: Urinalysis was identified as an invalid indicator for urolithiaisis in patients having acute renal pain. In patient with urolithiasis, abnormal urinalysis was more frequently seen when the calculus was smaller and moreover was impacted in the lower urinary tract
