ABSTRACT
Background. The urology departament at Hospital General of Mexico has a new litothriptor of fourth generation named Direx Duet, this litothriptor has the skill to have two source of energy from F1, therefore it has the sincronic and asincronic modes.
Objective. To describe the fragmentation effectiveness in urinary lithiasis using the litothriptor Direx Duet in two different modes.
Methods. Patients from the Hospital General of Mexico with urolithiasis diagnosis.
Results. The inmediatly fragmentation effective in the asincronic mode was 63.9% and to the sincronic mode 70.6% therefore there is not estadisticals difference among two groups, the follow at one mount the fragmentation rate was 88.5% and 96.2% to the mode asincronic and sincronic respectively.
Conclusion. 1. the inmediatly and late fragmentation among the asincronic and sincronic is similar. 2. The asincronic mode needs more voltage 21 Kv in contrast to sincronic mode 20 Kv in order to achieve adecuate lithiasis fragmentation.
