Laparo-endoscopic single-site (LESS) bilateral nephroureterectomy for patients with end-stage renal disease

We present the first report of LESS bilateral nephroureterectomy via the transperitoneal approach using the home-made single port. Two patients received LESS bilateral nephroureterectomies and bladder cuffs resection with homemade single ports, which were created by using an Alexis wound retractor as an access platform through a 4 cm incision. Distal ureters were resected through the same incision with Endo-loop. No additional ports were used and both procedures were completed successfully without traditional laparoscopic/open conversion or complication. LESS nephreoureterectomy with bladder cuff excision was performed in 460 and 635 minutes with an estimated blood loss of 50 and 400 mL, respectively. Patients were discharged on postoperative day 3 and 7, respectively. Our report demonstrates that LESS bilateral nephroureterectomy and bladder cuff resection is a safe and feasible procedure for urothelial carcinoma of upper urinary tract in patients at dialysis.
