  Abstract

 Background & Aims: Renal stone is a common disease in GU system. Differential diagnoses of this problem are appendicitis, ectopic pregnancy, torsion of ovarian cyst which are important to be differentiated from each other. Sonography is a procedure for diagnosis of stone but it cannot diagnose all of the ureteral stones. Ureteral stone produces obstruction leads to increased pressure in ureter and kidney. Increasing pressure in kidney decreases compliance of this organ and manifests as an increase in renal vein resistance. In this study we aimed to calculate renal compliance in obstructed and non-obstructed kidney.

 Materials & Methods: In a descriptive cross-sectional study we did Doppler on 33 patients with acute renal obstruction and calculated venous compliance and arterial resistive index (RI) in normal and obstructed kidney and reported the results by mean and percent.

 Results: The compliance in normal kidney was about 0.56 and in obstructed kidney was 0.34 so the compliance was lower in obstructed kidney. Arterial RI in obstructed kidney was above 0.63. This was below 0.62 in normal kidney. These two RIs are very near to each other though using arterial RI in comparison with using venous compliance seems to have less accuracy.

 Conclusion: This study showed that using renal compliance which decreases in obstruction is a suitable way for detection of obstruction.
