RENAL RESISITIVE INDEX (RI): A NEW DIAGNOSTIC PARAMETER FOR THE ASSESSMENT OF NEPHROPTOSIS Ferdinand Frauscher, Vinzenz Smekal. Gernot Helweg, Gijnter Janetschek, Hannes Strasser, Dieter zur Nedden, Georg Barisch Department of Radiology II and Urology, University of Innsbruck, Austria

Objectives: Nephroptosis leads to intermittent urinary obstruction and disturbances of renal perfusion. With advances in color Doppler ultrasound (CDU), we evaluated its efficacy in our patients. Methods: In 24 patients with a mean age of 28 years, nephropiosis was diagnosed radiographically. Further evaluation included CDU and isotope nephrography. The resistive index (RI) was assessed in the segmental arteries with the patient both supine and erect. The contra-lateral kidney served as a control. Results: Of 19 symptomatic patients, 15 had a decreased RI when erect (mean 0.15 + 0.06) on the affected side as well as abnormal scans. The RI was normal in all asymptomatic patients. Seven symptomatic patients with abnormal scans and RI underwent right-side laparoscopic nephropexy. Postoperatively, all seven kidneys showed no posture-dependent changes in RI. Conclusions: Our preliminary results indicate, that non-invasive CDU is a valuable tool in evaluating renal perfusion disorders and may be more specific than isotope nephrography in preoperative and follow-up evaluation of patients with nephroptosis.

Out of 647 men, 471 (72.8%) had a alight symptom and the remaining 176 (27.2%) had either a moderate (n=141) or severe (n=R5) symptom. Simple regression analysis demonstrated the strongest linear relationship between symptom acorea and PCAR(R=O. 167,p
