The retroperitoneal laparoscopic technique for treatment of complex renal stones was completely successful in 73 cases, while 2 cases were converted to open surgery (Table 2). The stone was difficult to remove in one case due to an intra-renal small pelvis, and in another due to severe perirenal inflammation caused by repeated extracorporeal shockwave lithotripsy. The stones were eliminated in 69 cases during operations, and residual stones were discharged by subsequent extracorporeal shockwave lithotripsy in 6 cases. Eight cases with UPJO received pyeloplasty. Three cases with nephroptosis received nephropexy. Two patients with retrocaval ureter and 2 with aberrant crossing vessels received ureteral chop amputation and reconstruction.

No serious intraoperative complication occurred in any of the 75 cases. The retroperitoneal drainage tube was removed 3–6 days after the procedure, the Foley catheter at 8 days and the stitches at 7 days. Sixty-eight patients experienced no urinary leakage after the operation. In other cases with urinary leakage, the drainage tube was removed less than 3 weeks after surgery. The double-J stent was extracted in outpatient clinic 1 month later. Ultrasonography, x-ray of the kidney, ureter and bladder, and intravenous urography were reviewed during 6–82 months of follow-up and no aggravating hydronephrosis was found.
