Abstract :
Purpose: To describe our technique and experience with retroperitoneoscopic upper pole nephroureterectomy
in duplex kidney, focusing on the role of dilated upper ureter.
Materials and Methods: From November 2004 to August 2011, retroperitoneoscopic upper
pole nephroureterectomy was performed in 31 patients with a duplex kidney by a single, experienced
laparoscopic surgeon. We developed our own surgical technique to suit this technically
challenging procedure. Follow-up studies were performed using renal ultrasonography, intravenous
urography (IVU) and/or dimercaptosuccinic acid (DMSA) renal scan in all patients at 3
months postoperatively and annually thereafter.
Results: All procedures were completed laparoscopically without conversion to open surgery
and blood transfusion. The mean operative time was 106 (90-157) min. The estimated blood
loss was < 50 mL in all cases. The mean postoperative hospital stay was 4.2 (3-7) days. Perioperative
complications were limited to 1 case of peritoneal tear during a procedure and 1 case
of transient postoperative fever. No major intraoperative and postoperative complication occurred.
With the mean follow-up period of 41 months (range 3 to 80), no case was observed to
have functional loss of the remaining lower moiety on postoperative IVU or DMSA renal scan.
Conclusion: Retroperitoneoscopic upper pole nephroureterectomy using our technique is safe
and effective.
