Modified Nephrometry Score With Body Mass Index More Accurately Predicts Ischemic Time in Transabdominal Laparoscopic Partial Nephrectomy for Small Renal Masses

To accurately predict the ischemic time (IT) and select candidates for transabdominal laparoscopic partial nephrectomy (LPN). Transabdominal LPN was performed for 135 Japanese patients with renal masses 4 cm, respectively. For tumor location (A), 1, 2, and 3 points were given for anterior, on the co...

Description
Summary:To accurately predict the ischemic time (IT) and select candidates for transabdominal laparoscopic partial nephrectomy (LPN). Transabdominal LPN was performed for 135 Japanese patients with renal masses 4 cm, respectively. For tumor location (A), 1, 2, and 3 points were given for anterior, on the coronal plane, and posterior, respectively. The median IT was 24.6 minutes. Using the original NS, 64, 65, and 6 patients were categorized into low (4-6), moderate (7-9), and high (10-12) complexity, respectively. With the modified NS, 42, 75, and 18 patients were categorized into low (5-7), moderate (8-11), and high (12-15) complexity, respectively. Pearson's correlation coefficient (R) between the original NS and IT was 0.297, whereas the R was improved to 0.388 when the modified NS was employed. If the modified NS was low complexity, 95.2% achieved IT
