Changes of renal blood flow in nephroptosis: assessment by color Doppler imaging, isotope renography and correlation with clinical outcome after laparoscopic nephropexy.

Objective: Previously, we have detected changes in renal blood flow secondary to nephroptosis by assessing the renal resistive index (RI) using color Doppler imaging (CDI). The aim of the current study was to compare two diagnostic methods, CDI and isotope renography (IRG), for detection of renal blood flow impairment in patients with nephroptosis.

Methods: 26 patients with nephroptosis and flank pain underwent CDI and isotope renography (IRG) before and after laparoscopic nephropexy.
