| - BACKGROUND: The value of tubal perfusion pressures assessed during selective salpingography and tubal catheterization in predicting fertility has not been investigated. METHODS: A total of 325 infertile women underwent selective salpingography and tubal catheterization. Pregnancy information was collected in 256 (78.7%). The 50th (300 mmHg) and 90th (500 mmHg) centiles of the tubal perfusion pressure distribution in women with normal tubes on selective salpingography were used as thresholds. Women were divided into three tubal perfusion pressure groups: good (both tubes <300, or one tube <300 and the other 300-500 mmHg), mediocre (both tubes 300-500, or one tube <300 and the other >500 mmHg) and poor (both tubes >500, or one tube > 500 and the other 300-500 mmHg). RESULTS: The pregnancy rate in the good perfusion pressure group was significantly higher than that in the poor perfusion pressure group, both when all non-IVF/ICSI first conceptions (P = 0.001) as well as when spontaneous first conceptions only were considered (P = 0.010). The pregnancy rate in the mediocre group lay between the good and the poor groups, though none of the comparisons reached statistical significance. CONCLUSIONS: Selective salpingography can provide additional diagnostic information in comparison with other tubal assessment tests. Tubal perfusion pressures may be predictive of future fertility.
