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. Surgery consists of a small classical lumbar flank incision proportional to a thumb finger in length. The Ottoni catheter is placed as an external stent (Fig 3). Patients stay in hospital overnight and remove the stent after 4 days PO.
