[A clinical experience of upper urinary tract disease using an endourological technic]

Fifty-three patients with upper urinary tract disease were treated by using endourological technique between July, 1986 and July, 1987; percutaneous nephrolithotripsy (PNL) in 26 cases, transurethral ureterolithotripsy (TUL) in 11 cases, endopyelotomy for ureteropelvic obstruction in 3 cases, dilation of ureteral stenosis in 3 cases and percutaneous nephrostomy in 10 cases. The stones could be successfully removed in 24 cases (92%) of PNL and 10 cases (91%) of TUL. No severe complications were seen in this series. The many reports of PNL and TUL were investigated in detail, but other endourological approach will need further long-term followup.
