Abstract：Objective:By summarizing the clinical data of robot-assisted laparoscopic technique for the treat-ment of unilateral multifocal renal tumors,to evaluate the safety and feasibility of this technique and improve the treatment level of this disease.Methods:Clinical data and prognostic information of 22 patients who were admitted to PLA General Hospital from November 2013 to April 2016 with the application of robot-assisted laparoscopic technique for the treatment of unilateral multifocal renal tumors were retrospectively analyzed.Results:All the 22 operations were successfully performed,and 4 cases were given radical nephrectomy because of high grade classifi-cations.This study included 21 males and 1 female with a mean age of 50.3 years old,11 patients with more than 2 tumor lesions,and 6 patients with the history of radical nephrectomy for the reason of renal tumor.The pre-op-erative creatinine was (94.83±19.73)μmoL/L,the post-operative creatinine 3 months after surgery was (146.10 ±54.79)μmoL/L,the warm ischemia time was (30.08±17.50)min,the estimated blood loss was (222.7± 306.5)mL,the postoperative hospital stay was (6.9±2.9)days,and the postoperative fasting days were (1.9± 0.8)days.Seventeen patients were undergone transperitoneal approach,5 patients were undergone retroperitoneal approach,and 6 patients were undergone robot-assisted laparoscopic renal artery cold perfusion surgery.The patho logical diagnosis confirmed that there were 2 1 cases of clear cell renal cell carcinoma and 1 case of papillary renal cell carcinoma,and no positive margin and lymph node metastasis was found.No recurrence or metastasis was observed during a follow-up period of 3 to 37 months.Conclusions:Robot-assisted laparoscopic technique for the treatment of unilateral multifocal renal tumors is safe and feasible,and its short-term tumor control and renal function reservation are satisfactory.However,further larger-scale researches with longer follow-up period were required.
