C79 ESWL for treatment of lower pole caliceal stone

      Introduction and Objectives

      Dornier Compact Delta is electromagnetic lithotripter designed with modules. ESWL makes it possible to treat most patients suffering from this disease,minimizing complications and side effects of treatment. The localisation of calculus is done with ultrasound and XR imaging. The goal of stone treatment is to use a less morbid, minimally invasive and effective modality.
      Optimal treatment of lower pole caliceal stone still controversial. The aim of our study was to determine the efficacy and safe of ESWL in patients with lower pole caliceal stone.

      Material and Methods

      We retrospectively analysed the charts and radiology films of patients who had ESWL for lower pole caliceal stone. For ESWL we use Dornier Compact Delta Lithotripter D. After the lithotripsy we followed patients at one and at three mounth and thereafter according to stone receding to stone residu. To the patients was given diclofenac supp. 20 min priory to treatment, for pain control during shock wave lithotripsy was given sedo-analgesia. The procedure was done with ultrasound, the patient in the supine positione and no more than 3000 shock wave were delivered, 60 shots per minute were applied using the maximal level of energy. Two hours after the procedure, the patients were released home. After ESWL combined with oral hydratation plus 12 degree inversion.


      Between April 2004 and June 2009, 267 patients (128 males and 139 females) were treated with ESWL because of lower caliceal stone large 6–25 mm. The mean age male of patients was 38.74 (from 8 to 64) females 40.27 (from 16 to 73) patients had stones in the lower caliceal stone. The average stone-free after single treatments 124, after second 34 after third 14, after fourth 4. The time between two season one month. In 9 patients ESWL failed. Complications haemathoma occur in one cases, clinical uroinfect occurred in 3 patients.


      ESWL appears to be an effective first-line treatment for lower pole caliceal stone. Our results showing good results in fragmentation and clearance of the stones in lower caliceal stone low adverse effects. Patients with SWPL greater than 100 mm are more likely to fail treatment.
