Approaches to the superior calix: renal displacement technique and review of options.
A new percutaneous approach to the superior calix has been implemented with reduced morbidity. To avoid intercostal or retrograde punctures or triangulation methods an Amplatz sheath passed through a central or lower pole calix can be pushed caudally while descent of the kidney is viewed fluoroscopically. An 18-gauge TLA needle passed through the initial skin puncture then is used to form a Y with the original tract. This method has been successful in 21 of 25 cases without complications. The only failures occurred in patients with immobile kidneys secondary to a previous operation.
