Rapid communication: first clinical experience with Doli S 220F-XP extracorporeal lithotripter for urinary lithiasis.
OBJECTIVE
To assess the initial results of the Dornier Doli S 220F-XP extracorporeal lithotripter for the management of solitary urinary calculi.


METHODS
We prospectively examined the outcome of shockwave lithotripsy (SWL) in the first 140 patients with solitary renal and ureteral lithiasis treated by one urologist with the new power Doli S lithotripter. Ninety-one patients (group A) had renal stones, and 49 patients (group B) had ureteral stones. Data were collected with respect to stone size, location, and fragmentation.


RESULTS
In group A, clinical success was documented in 77 patients (84%) at 1 month after lithotripsy. Three months after lithotripsy, 69 patients (75.2%) were stone free and 8 (8.8%) had fragments <4 mm. In group B, 41 patients (83%) achieved clinical success 1 month after lithotripsy. Thirty-eight patients (77%) were stone free 3 months after treatment, and 3 (6%) had fragments <4 mm. Seven patients (7%) in group A and three patients (6%) in group B required re-treatment. The overall efficiency quotient was 67%. No patient developed a perinephric hematoma. Ninety-four percent of the patients reported mild pain during lithotripsy. The majority (91%) mentioned that they were satisfied with this treatment modality for urinary lithiasis (mean visual analog scale satisfaction score 8).


CONCLUSIONS
The Doli S 220 F-XP is a safe and effective device for managing calculi throughout the urinary tract.
