PEREZ GONZALEZ, Domingo et al. Factors influencing on the fragmentation of gallbladder calculi by extracorporeal shock waves. Rev Cubana Cir [online]. 2004, vol.43, n.3-4. ISSN 0034-7493.

Extracorporeal shock-wave lithotripsy is one of the therapeutic variants for symptomatic gallbladder lithiasis. It was applied to 626 patients, 479 (76.6 %) females and 147 (23.4 %) males. 473 (69.9 %) were over 40. The indexes of complete fragmentation were higher in patients with a single calculus (79.5 %) of less than 20 mm of diameter (72.3 %·), radiotransparent (89.2%) and with densities under 50 Houndsfield units (72.6 %). 215 patients (34.3 %), 35 (5.6 %) and 11 (1.8 %) needed 2,3 and 4 treatment sessions, respectively. Finally, the fragmentation was complete in 332 (53.0 %), partial in 241 (38.5 %) and only 53 (8.5 %) were not fragmented. The value of the physical and imaging characteristics of the calculi in this process was demonstrated
