title: Introducing a new sealant applicator for easy, safe, and quick closure of a mini-percutaneous nephrolitholapaxy access tract.
abstract: OBJECTIVE
  To achieve better hemostasis after mini-percutaneous nephrolitholapaxy (mini-PCNL), we developed a new application device that can be used to close the renal-access tract with gelatin matrix hemostatic sealant (GMHS).
  
  
  METHODS
  After mini-PCNL was performed on 11 patients, a Double-J ureteral stent was placed antegrade. After retraction of the 18F Amplatz sheath out of the collecting system under vision without irrigation, the urothelium collapsed. The 15F metal applicator with a 10F working channel was then inserted and GMHS injected during further retraction of both the device and the Amplatz sheath. The skin was closed with Steri-strips.
  
  
  RESULTS
  The renal parenchymal tract of the mini-PCNL can be sealed in 15 to 50 seconds. Postoperatively, no urinoma was observed. All patients had an uneventful follow-up.
  
  
  CONCLUSIONS
  Closing the track of the mini-PCNL with the new application device and GMHS is a safe, easy, and quick alternative to the common nephrostomy tube.
