Clinical analysis of retroperitoneal laparoscopic partial nephrectomy on patient with incidental renal cell carcinoma / 中国综合临床

ABSTRACT

Objective To evaluate the safety and clinical efficacy of retroperitoneal laparoscopic partial nephrectomy (LPN) in patients with incidental renal cell carcinoma.Methods Twenty-six patients with T1 incidental renal cell carcinoma treated with retroperitoneal LPN from Dec.2011 to Oct.2013 were analyzed retrospectively.The operation time,warm ischemia time,intraoperative blood loss,complications and prognosis of perioperative periods were collected.Results All 26 cases were operated successfully without conversion to open or other surgery.The operation period was 90-190 minutes.Blockage of renal artery was applied in all 26 cases,and the warm ischemia time was 15-30 minutes.The intraoperative blood loss was 100-360 ml.The drainage was removed 3-7 days postoperatively,and the hospitalization period was 7-12 days.All cases were clear cell renal cell carcinoma by pathological examinations,and showed negative surgical margins.No complications such as postoperative bleeding,inflammation and leakage of urine were occurred.All cases had normal renal function during the follow-up of 3-25 months without local recurrence or distant metastasis.Conclusion Retroperitoneal LPN for the treatment of T1 incidental renal cell carcinoma is worthy of application with the advantages of safety,minimal invasiveness,fewer complications,quick recovery and good nephron-sparing functional recovery.
