Background: Multiple factors can account for surgical complexity during laparoscopic partial nephrectomy (LPN); severe adhesion of perirenal fat (PRF) is a crucial one. Consequent renal decapsulation can deem renorrhaphy a very challenging task. We propose a novel technique (synthetic renal capsule tailoring [SYRCT]) to facilitate renorrhaphy in decapsulated kidneys and suggest early decapsulation as a safe option in cases with severe PRF.Materials and Methods: We retrospectively analyzed perioperative results of this novel technique performed in cases with severe PRF. All cases were classified as high grade in the Mayo Adhesive Probability (MAP) score.Results: A total of six cases were performed with the SYRCT technique. All patients were male with a mean age of 70 years (62-76 years) and mean body mass index of 30 kg/m2 (23.66-33.86). Of the six cases, five were T1a and 1 T1b. Mean tumor size was 2.83 cm (range 1.2-6 cm). Mean operative time was 121 minutes (range 74-150 minutes); mean warm ischemia time was 17.2 minutes (range 13-25 minutes). Mean operative bleeding was 128 mL (range 50-250 mL). Mean hospital stay was 2.3 days. There were no surgical complications greater or equal to Clavien II.Conclusion: Performing complete renal decapsulation with subcapsular dissection and SYRCT in cases with high MAP score and severe PRF is safe and reproducible. Using this novel technique, we were able to obtain perioperative results comparable to the ones we found in LPN with normal PRF. [ABSTRACT FROM AUTHOR]
