Confirmation of the correct placement of lower end of DJ stent during open surgery: point of technique.

摘要

A simple technique to confirm the correct placement of the double J (DJ) stent at the time of antegrade insertion during open surgery is described. At the time of antegrade DJ stent placement about 30-50 ml of sterile methylene blue is instilled into the bladder. Appearance of methylene blue from the upper end and side holes of the DJ stent confirms the correct placement of the lower end of the stent.
