UT11 Ureteral diameter/L1–L3 [radiography] Ureteral diameter/age [radiography]
An evaluation of the upper urinary tract in children always includes the width of the ureters as well as possible distension of the renal pelvis and calyces. Any effective measure to assess if the widest part of the ureter is abnormally dilated must include a body reference such as age or, for conformity with other methods, the L1–L3 distance.
