The results of 272 patients who underwent percutaneous removal of renal and ureteral stones were presented. The stones were completely removed in 199 kidneys or ureters (70.8%), incompletelyremoved in 66 (23.5%) and could not removed in 16 (5.7%). The residual rate was 81.8% in complicated staghorn calculi, 33.3% in staghorn calculi, 48.2% in multiple calculi, 8.6% in simple calculus and 16.6% in ureteral calculus.
Major complications consisted of arteriovenous fistula (1 patient), pseudoaneurysma (1 patient), complete obstruction of ureteropelvic juncion (1 patient), sepsis (1 patient) and massive bleeding requiring more than 1000ml blood transfusion (13 patients). Two patients with vascular complications were managed by angiography with embolizations and the patient with ureteral damage had a reconstructive surgery ureterocalicostomy. The patient with sepsis was managed by appropriate antibiotic treatment.
The rate of residual calculi and major complications in this procedure were higher than that in the open surgery. There were some difficulties in completely removing complicated staghorn calculi and multiple calculi through this procedure. The indication of this procedure was discussed.
