Abstract:Objective:To evaluate our surgical techniques and experience with retroperitoneal laparoscopic upper pole nephroureterectomy duplex kidney in adult patients.Methods:A total of 27 adult patients with duplex kidney underwent laparoscopic upper pole nephroureterectomy. Retroperitoneal approach was used in all of our patients. The upper pole renal parenchyma was completely mobilized and then we mobilized and transected the ureter, renal artery and renal vein respectively. The upper pole renal parenchyma was divided circumferentially from the lower kidney using an endo-scissors, and the parenchyma was closed by running suture with 2-0 Vicryl. Renal ultrasonography and IVU were performed on 3 and 6 months postoperatively to evaluate the renal function.Results:All laparoscopic operations were performed successfully without conversion to open surgery. The mean operative time was 146 minutes. The mean blood loss was 120 ml. No intraoperative or major postoperative complications occurred. The mean postoperative hospital stay was 7 days. The ultrasound and IVU of 3 and 6 months postoperatively demonstrated normal renal function and no perirenal fluid collection.Conclusions:Retroperitoneal laparoscopic upper pole nephroureterectomy is a safe and effective procedure and an excellent minimally invasive treatment option for the adult patients with duplex kidney.
