Adherent Perinephric Fat in Asian Patients: Predictors and Impact on Perioperative Outcomes of Partial Nephrectomy

Abstract

Introduction: This study is aimed at evaluating the incidence and predictors of adherent perinephric fat (APF) in Asians during partial nephrectomy (PN), and determining the impact of APF on perioperative outcomes. Materials and Methods: A total of 231 Asian patients with renal tumors underwent PN, and their Mayo adhesive probability (MAP) score was calculated. APF was intraoperatively determined, and the perioperative data were compared according to the presence of APF. The predictors of APF were examined using logistic regression analyses. Results: APF was observed in 40 (17%) patients. In multivariate analysis, male gender and higher MAP score were the independent predictors of APF. The estimated blood loss was higher in patients with APF, however, the complication rates did not differ between the 2 groups. Conclusions: The MAP score can predict APF in an Asian population. The presence of APF was associated with greater blood loss; however it did not increase the postoperative complications in PN.
