U.S., Aug. 8 -- ClinicalTrials.gov registry received information related to the study (NCT07751796) titled 'OptiCross HD IVUS for Assessing Invasion Depth in Upper Tract Urothelial Carcinoma' on Aug. 03.
Brief Summary: Upper tract urothelial carcinoma (UTUC) is difficult to stage accurately because cross-sectional imaging and ureteroscopic biopsy may not reliably demonstrate muscular or periureteral invasion. This exploratory study evaluates whether a 60-MHz OptiCross HD intravascular ultrasound (IVUS) catheter can be safely introduced into the renal pelvis or ureter during planned surgery and provide intraluminal images that correspond to the final pathologic T stage.
Fifteen adults with suspected or confirmed UTUC who are already schedu...
