In robot-assisted partial nephrectomy (RAPN) renorrhaphy is used to achieve hemostatic control of the tumoral resection bed, with detrimental impact on renal function. Hemostatic agents are used to achieve rapid and optimal hemostasis. GATT-Patch is a new hemostatic sealant that has already demonstrated promising results. Compare GATT-Patch and standard renorrhaphy in terms of hemostatic capacity, ischemia time, and prevention of urinary leakage after RAPN in a porcine model. In this preclinical randomized controlled trial, four pigs underwent 32 RAPNs. After resection, GATT-Patch application and performance of classic renorrhaphy were randomized. After the procedure, the resection bed was reinspected. A necropsy study evaluated the adhesiveness of the patch, and retrograde pyelography was performed to determine the leakage burst pressure. Application of GATT-Patch and performance of classic renorrhaphy were randomized and surgeons blinded to the hemostatic technique to be performed. Warm ischemia, hemostatic control, active bleeding during hemostatic control, total procedure time, bleeding at reinspection, and presence of urinary leakage on retrograde pyelography were recorded. Continuous variables were compared using the Student t-test. Categorical variables were compared using the Chi-square or Fisher's exact test. GATT-Patch reduced warm ischemia time (WIT), time to achieve hemostatic control, active bleeding time, and total procedure time, achieving hemostasis in 100% of the cases. Rebleeding at reinspection occurred in 0% of the GATT-Patch group. Renal parenchyma damage was observed in 100% of renorrhaphy cases and in 0% of GATT-Patch cases. GATT-Patch guaranteed optimal hemostasis and urine sealant effect after RAPN in porcine models. Compared to renorrhaphy, we observed a reduction in WIT, total procedure time, and potential reduction in healthy parenchyma loss. GATT-Patch stops bleeding and provides hemostasis faster than suturing after resection of portions of the kidney in pigs. It might be tested in patients undergoing partial nephrectomy for kidney cancer.

D007668	Kidney	Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.	Kidneys

D009392	Nephrectomy	Excision of kidney.	Heminephrectomy,Heminephrectomies,Nephrectomies
D006487	Hemostasis	The process which spontaneously arrests the flow of BLOOD from vessels carrying blood under pressure. It is accomplished by contraction of the vessels, adhesion and aggregation of formed blood elements (eg. ERYTHROCYTE AGGREGATION), and the process of BLOOD COAGULATION.	Hemostases
D006490	Hemostatics	Agents acting to arrest the flow of blood. Absorbable hemostatics arrest bleeding either by the formation of an artificial clot or by providing a mechanical matrix that facilitates clotting when applied directly to the bleeding surface. These agents function more at the capillary level and are not effective at stemming arterial or venous bleeding under any significant intravascular pressure.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013552	Swine	Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).
