Robot-assisted retroperitoneal partial nephrectomy for partial nephrectomy: an analysis of 118 cases

Abstract

Objective To analyze the clinical data of the patients undergoing robot-assisted retroperitoneal partial nephrectomy (RARPN) and investigate the surgical points and advantages of the surgery. Methods Clinical data of 118 patients undergoing RARPN in our department from June 2011 to June 2018 were collected and retrospectively analyzed in this study. Their age, body mass index (BMI), R.E.N.A.L. score, operation time, warm ischemia time, amount of blood loss, length of hospital stay, postoperative complications, and data during follow-up were analyzed statistically. Results The operation was successfully completed in all 118 patients. The operation time was 127.6±34.5 min, warm ischemia time 19.8±5.1 min, amount of bleeding 97.3±67.3 mL, postoperative drainage time 2.7±0.6 d, intestinal exhaust time 1.9±0.7 d, and length of hospital stay 6.0±0.9 d. The operation time and warm ischemia time were significantly shorter in T1a stage patients than T1b stage patients (P 24 kg/m2), removal of perinephric fat is also a good way to complete the surgery.
