We report on the use of a new catheter, the kidney internal splint/stent (KISS), to facilitate renal urine drainage following pyeloplasty. The catheter combines the desirable qualities of nephrostomy tube diversion, anastomotic stent, and trocar placement in a single tube. The special construction of its lumen diminishes the likelihood of obstructed drainage. Our experience using the KISS catheter with 31 patients undergoing pyeloplasty shows it provides effective internal and external urinary diversion.
