toothpaste sign

A descriptor for a column of dense radiocontrast that has passed through a narrowed ureteral opening at the trigone and lies in a toothpaste-like fashion on the bladder floor; this finding may be caused by postoperative contraction of the vesical neck, as may occur in TURPs, as well as in suprapubic and perineal surgery
