Abstract：Objective: To compare the patients' perioperative outcomes and evaluate the impact of different robotic assistants in retroperitoneal robot-assisted partial nephrectomy (RPRPN) by single surgeon. Methods: We retrospectively analyzed the clinical features and perioperative outcomes of 59 patients who underwent retroperitoneal robot-assisted partial nephrectomy (RPRPN) by single surgeon and different assistants in the Department of Urology, PLA General Hospital from June 2015 to July 2016. Age, gender, BMI, preoperative serum creatinine level, comobidities, abdominal operation history, RENAL score, PADUA score as well as operation time, estimated blood loss, warm ischemia time, postoperative drainage, fasting time, complications, length of indwelling drainage, postoperative hospital stay and the postoperative serum creatinine levels were recorded and analyzed. Results: The baseline of patients in different assistants was similar. The difference in operation time and length of indwelling drainage between different assistants was statistically significant (P=0.0324 and P=0.0016). However, the difference in the other perioperative outcomes was not statistically significant. Conclusions: Robotic assistant played an important role in the RPRPN, and different assistant surgeon had some impact on the operative time and length of indwelling drainage, but had little impact on other indicators.
