Abstract
To assess the yield of both urinalysis and abdominal ultrasound in diagnosing renal colic and abdominal pain at King Hassein Medical Centre in Amman, Capital city of Jordan. Methods: Eight hundred and forty three successive patients presented to the emergency room at King Hussein Medical Centre Hospital between August 2004-March 2005 with abdominal pain and flank pain mimicking renal colic. All patients gave complete medical history, and underwent physical examination and urine analysis invesgation for pyuria, hematuria and/or crystalluria. Then they had abdominal ultrasound and 51 patients had plain abdominal radiograph. Urine analysis and abdominal ultrasound examinations were evaluated using 2 x 2 contingency table for sensitivity, specificity, positive and negative predictive values. (Mean age (±SD) was found to be 33.2 ± 11.66 years; (range 15-60). Male: Female ratio was (1.4:1).) There were 72 (8%) abnormal urinalysis (pyurea, hematuria) and 222 (26.3%) abnormal abdominal U/S. Sixty-nine (24.5%) cases were related to urinary tract and prostate. Nephrolithiasis dominated the ultrasonic findings (44.9%) followed by hydronephrosis (33.3%), small kidneys in 5.8%, prostate pathology, 4.3%, double kidneys, nephrectomy and renal cyst in 2.9% each. Adult polycystic kidney disease and horseshoe kidneys constituted (1.5%). Non-renal ultrasonic findings included gall bladder stones found in two patients, epigastric mass, intrapelvic mass in one female nd hepatosplenomegaly in one patient. Combined urine analysis and ultrasound had a sensitivity of 12% (95% CI: 4-19) and specificity of 92% (95% CI: 89-96). Positive predictive value was 33% (95% CI: 14-52). While combined ultrasound and kidney, urinary bladder had a sensitivity of 83% (95% CI: 62-104) and a specificity of 60% (95% 17-103). The predictive value for positive results was 83% (95% CI: 62-104) and the predictive value for negative results was 60% (95% CI: 17-103). Nephrolithiasis and hydronephrosis constutute the major causes of renal colic in Amman/Jordan.
