title: Ureteric stone management using a second generation lithotriptor.
abstract: A series of 209 consecutive patients with ureteric calculi underwent 296 extracorporeal shock wave lithotripsy treatments on the Siemens Lithostar over a 25-month period; 123 stones were upper ureteric, 30 mid-ureteric and 56 lower ureteric; 46.9% were right-sided stones, 53.6% were left-sided and 0.5% (1 patient) were bilateral. On referral, 60 patients had stents and 15 had nephrostomies for obstruction. All treatments were performed without anaesthesia except for 9 patients in whom stent insertion or ureteroscopic manipulations were attempted concomitant to ESWL. The average number of treatments was 1.42, with 27.5% of patients requiring more than 1 treatment. The average number of shocks per treatment was 3995 and the average hospital stay was 1.79 days. Complete clearance of the stone was achieved in 82% of upper ureteric stones, 89% of mid-ureteric and 80% of lower ureteric stones. The facility for X-ray localisation of stones allows a high proportion of ureteric calculi to be treated successfully by ESWL, including the more taxing middle and lower ureteric calculi.
