Introducing a new sealant applicator for easy, safe, and quick closure of a mini-percutaneous nephrolitholapaxy access tract.

Purpose: 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).

Patients And 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.
