Tandem Resonance stent placement steps. (a) The introducers are positioned in tandem such that the radiopaque markers are seen overlying the renal pelvis. (b) The Resonance stents are advanced through the introducers simultaneously. (c) The distal ends of the stents are observed as the introducers are withdrawn with care not to advance the distal aspect of the stents into the ureter. (d) The introducers are completely removed allowing the distal aspects of the stents to curl within the bladder.
