title: [How to identify the neck of a caliceal diverticulum in flexible ureterorenoscopy].
abstract: A caliceal diverticulum corresponds to a cavity communicating with the renal excretory tract via a neck. Surgical treatment is required when the caliceal diverticulum is symptomatic with repercussions on the patient's quality of life. A retrograde approach via holmium:YAG laser ureterorenoscopy has been recently used to treat the stone and externalize the caliceal diverticulum into the pyelocaliceal cavities. The problem raised by this approach is identification of the diverticular neck. The objective of this technical note is to describe a technique to facilitate identification of the diverticular neck.
