Endoluminal sonography (IVUS) performed with 12.5 MHz miniature transducer-containing catheters, diameter 6 or 9 Fr, is a new techinque for the study of ureter and pelvis. With this new method it is possible to diagnose a variety of abnormalities, such as: transitional cell carcinomas, opaque stones, clots and inflammatory diseases of upper urinary tract. This new US technique is useful in the study of excretory tract minus (detected with urography) and it gives more information than CAT or RMN in the study of transitional cell carcinoma of ureter and pelvis. IVUS must be performed before URS since it provides important information for therapeutic decisions; endoluminal sonography is also useful in the follow-up of patients undergoing conservative therapy for TCC.
