Abstract: (15255 Views)
Background and purpose: Çlinical symptoms of obstructive ureteral stones are very disturbing. Ïnfection, hematuria and renal insufficiency are its complications. Ïn the recent decades ÏVP has been a selective standard method in diagnosis of the causes of ureteral colic. But in many cases there are contraindications and limitations in this procedure.
The aim of this study was to determine the accuracy of ultrasound and ÏVP in diagnosis of ureteral stones as a common cause of ureteral colic.
Materials and methods: This was a prospective study in order to determine the diagnostic efficiency of two instruments. Total of 41 Patients with mean age of 34.4 years were referred by urologists to this center from february to july 1999. Sonography was performed by a radiologist and interpretation of ÏVP was done by another radiologist.
Results: Fourty one Patients were taken in to study, but 27 Patients with ureteral stones were diagnosed. Sensitivity and specificity of sonography in diagnosis of ureteral stones were 88.8% and 92.8% respectively This method showed that PPV= 96% and NPV= 81.2% Ïn case of ÏVP, the sensitivity and specificity was 96.2% and 92.8% respectively, PPV= 96.2% and NPV= 92.8%
Çonclusion: This study reveals that, sensitivity and specificity of sonography for the diagnosis of ureteral stones can compete completely with ÏVP. Hence, considering the contraindications of ÏVP, it can be proposed as a primary diagnostic method.
