Ureter diameter and ureteral access sheath in duplicated ureters

Do you think the ureter size in duplicated collecting system is smaller than that in the normal one? Maybe yes especially at the junctional area. You can see the whitish ischemic mucosal change after I removed the 11/13 access sheath.​ Therefore, we can consider the sliding technique over the guidewire without use of the access sheath or we should try to shorten the operative time...
