S107 ESWL monotherapy as primary modality of treating upper uretheral stones

      Introduction and Objectives

      Objectives: to present our experience with shock wave lithotripsy (ESWL) as a primary modality of treatment for upper uretheral stones.

      Material and Methods

      From January 2006–June 2008 84 patients with upper ureteric stones were treated with ESWL as the primary modality with Siemens-Compact lithotripter. Aged 16–71 years old, male-female, ratio 2, 1–1, stone size 7–12 mm, pyuria was 0/84, clinical infections, 5/84, pre ESWL double J stenting 0/84, intanenous sedation 84/84, duration of symptoms under 4 weeks 28/84, after 4 weeks 56/84, stone size less than 10 mm 63/84, more than 10 mm 21/84/ The patients were examined with sonography, intravenous urography, BUN, creatinin, microscopic urine examination.


      The clearance rate was 96% for stones less than 10 mm and 85% for stones larger than 10 mm.


      ESWL as monotherapy has best results (overall success rate was 95%) when the stones were less than 10 mm, minimal analgesia ir required with modern lithotripters.
