summary

Introduction and the aim of the study. Treatment of patients with stones located within the lower part of ureter may involve shock waves generated extracorporeally or crumbling during ureteroscopy. The rules of choosing the proper method are not fully established. We evaluated the effectiveness of ESWL in the treatment of patients with stones located within the lower part of ureter in the "One Day Stay" Department.
Materials and method. We evaluated 129 patients with stones located within the lower part of ureter, who between January 2004 and September 2005 were treated by ESWL.We used electrohydraulic lithotriptor "Econolith 2000". The short term and long term efficacy were evaluated by measuring stones size, (BMI) and the time of stay of the stone within the ureter.
Results. Complete stone elimination was achievied in 89 patients (69.7%), good results in 4 (3.1%), satisfactory in 6 (4.7%), poor results in 29 patients (22.6%). The biggest size of the stones were - 7.28 mm in the first group, 7.25 mm in the second one, 7.33 mm in the third and 9.15 mm in the fourth. The durations of symptoms were: 20 days in the first group, 23 days in the second, 79.7 days in third group, 35.7 days in the fourth group. 171 sessions were done in 129 patients. BMI in the first group was 25.7; in the second - 25.08, in the third group - 26.05 and 26.44 in the fourth group. No complications were observed.
Conclusions. ESWL is effective treatment modality in case of stones located within the lower part of ureter even in patients with long duration of symptoms. Good candidates for the treatment are patients with rather small deposits (<7 mm) and with short duration of symptoms. For these patients ESWL should be the first choice modality.
