Methods The nephropathy was extended to F14-F16 through invasive percutaneous.A small size of ureterscope F8/ F9.8 was used to take stones and the crushed stones were pushed out by pulse water pressure. 1下载后可任意编辑 Results Among 23 cases,5 were pretreated by percutaneous nephropancture and treated secondary PCNL. The rest 18 cases were treated with first PCNL.One to three tracts were used in all cases. There were 18 cases showed stone-free after treated with one-stage minimally invasive percutaneous nephrolitho tomy. Only one case with pyonephrosis suffered from postoperative infect appeared shock while one-stage minimall...
