Resumen
Objetivo

Valoramos de una manera cuantitativa el grado de molestias y dolor de las biopsias y evaluamos la eficacia del gel de lidocaína intrarectal.

Método

Realizamos un total de 140 biopsias transrectales de próstata ecodirigidas (BTPE) por sospecha de adenocarcinoma prostático. Los pacientes fueron incluidos de forma aleatoria y homogénea en dos brazos, uno recibió gel de lidocaína, 20 mg (Xylocaina®), intrarectal (grupo 1, n = 71) y el otro placebo, lubricante sin anestesia, (grupo 2, n = 28), diez minutos antes del procedimiento.

Resultados

La mediana global de dolor fue de 3,7 (0 no dolor y 10 máximo de dolor) y de molestias de 3,5. Los pacientes del grupo 1 (Xylocaína®) mostraron una tendencia a presentar menos dolor y molestias aunque no alcanzó el grado de significación deseado (p = 0,7 y p = 0,5, respectivamente).

Conclusiones

En nuestro medio no obtenemos los resultados descritos por otros grupos en cuanto a la disminución del dolor con el uso de gel intrarectal de anestesia tópica. No hemos encontrado diferencias significativas en cuanto a nivel de PSA, biopsias previas realizadas, uso del gel de lidocaína y grado de información recibida que afecten al grado de molestias y dolor.

Abstract
Objective

To know in a quantitative manner the degree of discomfort and pain of the biopsies of the prostate and to evaluate the effectiveness of the transrectal lidocaine.

Material and method

We performed 140 transrectal biopsies of the prostate. Patients were included on a random basis into two arms: one of them received intrarectal lidocaine, 20 mg (group 1, n = 71) and the other group received placebo (group 2, n = 28) both of them ten minutes prior the proceeding.

Results

The global pain mean was 3.7 (0 no pain, 10 highest pain) and the global discomfort mean was 3.5. The group 1 patients showed a trend to feel less pain and discomfort although it did not reach the necessary statistic significance (p = 0,7 y p = 0,5 respectively).

Conclusions

We do not achieve the good results obtained by other groups in order to decrease the degree of pain and discomfort with the use of intrarectal lidocaine. We did not find relationship between the PSA level, previous biopsies, intrarectal lidocaina and degree of information received and the degree of pain and discomfort.
