RESUMEN La evaluacion de la permeabilidad tubarica es un paso esencial en el estudio de la infertilidad femenina. Existen varios metodos que permiten realizar esta evaluacion. La histerosalpingografia (HSG) se ha consi-derado el metodo estandar, sin embargo es conocida su limitacion en la evaluacion de la obstruccion proxi-mal con alta tasa de falsos positivos. Presentamos una tecnica alternativa para la evaluacion por medio de cromotubacion histeroscopica, que tiene entre otras, la ventaja de permitir la evaluacion del factor uterino y tubarico en un solo paso y ademas, supera la dificultad de los falsos positivos de la HSG, en cuanto a la obstruccion proximal.PALABRAS CLAVE: Histeroscopia, infertilidad, trompas uterinas, salpingografia,histerosalpingografia SUMMARY The evaluation of tubal patency is an essential step in the study of female infertility. There are several me-thods to perform this evaluation. Hysterosalpingography (HSG) has been considered the standard method, however it is known to limitations in the assessment of proximal obstruction with high false positive rate. We present an alternative technique for evaluation by hysteroscopic chromo tubation, which has among others, the advantage of allowing the evaluation of uterine and tubal factor in one step and also overcomes the difficulty of false-positive HSG, as to the proximal obstruction.
