Endoluminal sonography performed with 12.5 MHz miniature transducer-containing catheters with diameter of 6 or 9 Fr., is a new technique for the study of urinary tract. We studied: U.S. scan of 10 corpes and 10 operatory specimens (bladders and kidneys) with anatomic measurement in vitro. U.S. scan of 20 patients "in vivo" with pathologies involving bladder and upper urinary tract. We studied the normal anatomy of bladder and ureter by U.S. and we detected the structures beyond the ureteral lumen as: vessels, lymph nodes, muscle. Our indications for the utility of this new U.S. technique are: Detection and staging of superficial T.C.C. of the bladder. Detection of dangerous vessels near the U.P.F before endopielotomy. Excretory tract minus (endoluminal ultrasound is helpful in differentiating such pelvic filling defects as blood clots, no opaque stones and transitional cell carcinoma).
