The role of selective salpingography and tubal catheterization in the management of the infertile couple.

PURPOSE OF REVIEW: This review is intended to update the reader about recent developments in the field of selective salpingography and tubal catheterization, to offer an interpretation of the information presented and to suggest further research links.

RECENT FINDINGS: The measurement of tubal perfusion pressures at selective salpingography and tubal catheterization has offered a new dimension in the evaluation of the fallopian tube. A classification of infertile women based on tubal perfusion pressures is presented, and this is correlated with the possibility of spontaneous fertility, thus giving selective salpingography and tubal catheterization a prognostic profile in addition to diagnostic and therapeutic functions. Experience derived from the use of the technique in unselected infertile women (i.e. not with proximal tubal blockage) is presented. The use of selective tube catheterization for sterilization purposes joins the mainstream with the publication of the encouraging results of a multinational trial. The debate on the validity of the diagnosis of proximal tubal blockage is enriched by the suggestion that simply rotating the patient during hysterosalpingography will resolve most cases of the condition. The fertility gain by single-tube recanalization in women with unilateral proximal tubal blockage is given further support. The use of oil-based media for selective salpingography and tubal catheterization is discussed. A hypothesis on the pathophysiology of proximal tubal blockage is presented.

SUMMARY: The evidence clearly supports the use of selective salpingography and tubal catheterization for infertile women with proximal tubal blockage. The potential of the technique to play a wider role in the management of infertility is demonstrated by recent research.
