The mini-flank lumbotomy for pyeloplasty in association with the Ottoni pyelostent: An inexpensive and efficient combination.

Pyeloplasty at an early age (<2 years) can be treated by a flank open, laparoscopy or robotic approach. We want to demonstrate our strategy and how to construct a very inexpensive pyelostent from a Foley tube. The Ottoni catheter is made from a Foley tube, sectioning the proximal end keeping a plastic circular basement for fixation to the skin.
