Surgery-pregnancy time intervals after salpingolysis, unilateral salpingostomy, and bilateral salpingostomy

Pregnancy rates and time intervals to achieve pregnancy were determined in 144 patients treated for infertility by lysis of bilateral tubal or peritubal adhesions. The pregnancy rate after bilateral salpingostomy for hydrosalpinges was low (18.7%; n = 91). The eventual pregnancy rate after unilateral salpingostomy with bilateral division of adhesions (43.8%; n = 16), however, was comparable to that after bilateral salpingolysis for purely peritubal adhesions (54.1% n = 37). In contrast, the mean surgery-pregnancy time interval was substantially longer after unilateral salpingostomy (104 weeks) than after bilateral salpingolysis (45 weeks) (P < 0.01). These findings indicate that salpingo-oophorectomy may be preferable to salpingostomy for unilateral hydrosalpinx.
