This study aimed to assess the validity of nephrometry scoring systems towards aiding the preoperative planning of laparoscopic partial nephrectomy (PN). Patients and Methods: Data of 77 patients who underwent partial nephrectomy at the Puerto Real University Hospital between January 2011 and December 2017 were retrospectively analyzed. Statistical analyses were carried out to determine whether there was an association between the complexity of the surgical procedure and the assigned nephrometry scores. Results: Operative complications (bleeding volume, conversion to open surgery, perioperative bleeding, and postoperative fistula) were significantly associated with independent variables (age, sex, body mass index, radiological tumor size, and operative ischemia time) and with the classification of patients using arterial-based complexity (ABC) and radius endophytic/exophytic nearness anterior-posterior location (RENAL) scores. There was also a strong correlation between the RENAL and ABC scores [Cramer’s V coefficient (0.682) and Fisher’s test (p<0.0001)]. Conclusion: The RENAL and ABC scores are associated with the risk of the complexity of partial nephrectomy for T1 renal tumors, even for ≥T1b tumors and/or with complex anatomical features. ER -
