Abstract

AIM:

To report our preliminary series with the Doli S EMSE 220F-XXP, the upgraded version of the previous Dornier Lithotripter S EMSE 220, for treatment of ureteral stones.

METHODS:

Since July 2006, a total of 200 patients with ureteral stones were submitted to shock wave lithotripsy (SWL) with Doli S EMSE 220F-XXP. Mean stone size was 9.3 mm (range 6-18 mm). Ureteral stone location was proximal in 75, middle in 34, and distal in 91. Follow-up was carried out at 6 weeks after the treatment, by means of kidney-ureter-bladder (KUB) film and ultrasound, or helical computed tomography (CT).

RESULTS:

The overall stone-free rate was 89.5%, and the effectiveness quotient was 80. Stratifying by stone site, the stone-free rate was 93.3, 67.6, and 94.5% for proximal, middle, and distal location, respectively. Mean number of sessions per patient was 1.14. Analgesia with intravenous ketorolac or tramadol was required in 42.5% of cases. No significant side-effects were recorded.

CONCLUSIONS:

The new Doli S EMSE 220F-XXP provides similar characteristics to the Doli S EMSE 220 in terms of safety and lack of major complications, when dealing with ureteral stones; the improvement in stone disintegration is particularly evident for distal location, for which the number of pulses and the intensity of treatment can be greatly increased and the upgraded power of the device can be widely applied.
