Accuracy of Uitra Sound in Diagnosis of Renal Stones Thesis

Abstract

To illucidate the diagnostic accuracy of U/S in the detection of renal stones we performed a blind comparative study of ultra sonography and I.V urography. In 160 kidneys with 130 stones about 50 stones smaller than 6mm were over looked by U/S. Whereas all stones 6mm or larger were correctly detected. In one case of uric acid stone disease I.V urography was inconclusive in determining the true nature of a renal pelvic filling defect, whereas us correctly diagnosed a stone. We conclude that ultra sonography gas a place in diagnosis and control of renal stones. Through this study I collect 160 cases. Most of them male (renal stone common in male) and between age of 20-40 years, some of them asymptomatic some patients have uretric stone that not seen by U/S because of bowel mainly in middle part of the ureter (obscured by gases). But U/S can detect the effect of stone, which is backpressure effect. We combine the U/S with KUB X–ray to increase sensitivity for detection of rend stone and manage the patients accordingly
