To explore the value of perirenal fascia of the right kidney in transperitoneal laparoscopic nephrectomy.

The feature of perirenal fascia was studied in order to design the fascial approach and the method of departure for the transperitoneal laparoscopic nephrectomy, base on the study of perirenal fascia and CT of the morphologic features of perirenal fascia. The perirenal fascia intraoperation,operation time, blood loss and the complications were observed in the 45 patients in our hospital from January 2015 to June 2019.

There was a bloodless layer fulled with fibrous bands surrounded the perirenal space, this bloodless layer was located between the adjacent perirenal fascias. All surgeries of 45 cases were performed successfully as the method that designed preoperatively, 42 cases kept the integrity of the fascia, but 2 cases with pyonephrosis and 1 case with non-functioning kiney could not be kept the integrity of the fascia. average operation time was 73 mins, average blood loss 50 ml, average drainage time 2.7 days, no inferior vena cava and bowel injries occurred. No perioperative death occurred.

The layered structure of the perirenal fascia and the bloodless layer surrounded the perirenal space provide a helpful anatomic evidence of transperitoneal laparoscopic nephrectomy. The fascial approach of transperitoneal laparoscopic nephrectomy is safe and feasible.
