PURPOSE: to verify the ratio of intra-uterine gestation in patients submitted to recanalization in the Hospital Regional da Asa Sul in the last 30 years and to assess the rate of ectopic gestation of such procedures, the influence of age and time interval between salpingectomy and recanalization in the therapeutic success. METHODS: medical files of 71 patients were analyzed, after exclusion of those presenting other alterations that could influence fertility prognosis, plus the cases when recanalization was impossible. Variables collected were: occurrence of intra-uterine gestation, coming to term or to abortion; occurrence of ectopic pregnancy after salpingectomy; no-conception after reversion, women's age at the recanalization, and time interval between salpingectomy and its reversion. RESULTS: there has been a pregnancy rate of 67.6%, 73.2% for bilateral recanalization and 46.6% for unilateral, as well as 5.6% of ectopic pregnancies. Concerning the patients' age group, it was observed a pregnancy rate of 33%, from 20 to 24; 60%, from 25 to 29; 69.2%, from 30 to 34; 65%, from 35 to 39, and 42.9%, from 40 to 44 years old. The number of cases was small for age the groups 20 to 24 and 40 to 44 years old. The time interval between salpingectomy and recanalization (TISR) has varied from one to 18 years. TISR has been divided in three groups presenting the following pregnancy rates: one to six year interval, 59%; seven to 12, 66.6%; 13 to 18, 57%. CONCLUSIONS: gestation rate has been 67.6%, 5.6% being ectopic. In the comparison of age groups, there has been no significant influence of age on the therapeutic success of patients from 25 to 39 years old. Sterility duration did not influence the reversion results.
