RESUMEN
La litotricia por ondas de choque extracorpóreas es una de las variantes terapéuticas para la litiasis vesicular sintomática. Se aplicaron en 626 pacientes 479 (76,6(por ciento) del sexo femenino y 147 (23,4(por ciento) del masculino, con más de 40 años de edad en 473 (69,9(por ciento). Los índices de fragmentación completa fueron mayores en los pacientes con cálculos únicos (79,5(por ciento), de menos de 20 mm de diámetro (72,3(por ciento), radiotransparentes (89,2(por ciento) y con densidades inferiores a las 50 unidades Houndsfield (72,6(por ciento). Necesitaron 2, 3 y 4 sesiones de tratamiento 215 pacientes (34,3(por ciento), 35 (5,6(por ciento) y 11 (1,8(por ciento) respectivamente. Finalmente la fragmentación fue completa en 332 (53,0(por ciento), parcial en 241 (38,5(por ciento) y solo no fragmentaron 53 (8,5(por ciento), donde se demostró el valor de las características físicas e imagenológicas de los cálculos en este proceso(AU)
ABSTRACT
Extracorporeal shock-wave lithotripsy is one of the therapeutic variants for symptomatic gallbladder lithiasis. It was applied to 626 patients, 479 (76.6 percent) females and 147 (23.4 percent) males. 473 (69.9 percent) were over 40. The indexes of complete fragmentation were higher in patients with a single calculus (79.5 percent) of less than 20 mm of diameter (72.3 percent·), radiotransparent (89.2 percent) and with densities under 50 Houndsfield units (72.6 percent). 215 patients (34.3 percent), 35 (5.6 percent) and 11 (1.8 percent) needed 2,3 and 4 treatment sessions, respectively. Finally, the fragmentation was complete in 332 (53.0 percent), partial in 241 (38.5 percent) and only 53 (8.5 percent) were not fragmented. The value of the physical and imaging characteristics of the calculi in this process was demonstrated(AU)
