Various techniques of metroplasty were performed in 32 cases of double uterus. In these patients the fetal survival rate before the operation was nil, whereas post-operatively it reached as high as 92.6%. Strassmann's operation was carried out in 16 cases, Jones & Jones's modified method in 12 cases and Tompkins's operation in 4 cases. The merits and demerits and the applicability of each technique and the various types of uterine malformation are discussed. It is concluded that a correct diagnosis of uterine malformation can only be established by a combination of precise HSG with direct macroscopical observation of uterine body. The Strassmann transverse incision is well suited for a bicornuate uterus, and Jones & Jones's wedge-shaped fundal resection for a partial septate uterus. The postoperative deformation in the fundus uteri is most frequently seen after the application of Strassmann's method, and is much less common with the modified method of Jones & Jones. Metroplasty can be applied in such cases of uterine malformation as when primary sterility is complained of but where any other cause for sterility is ruled out or is deemed to be corrected. Maximum care should be taken to prevent postoperative adhesion. Three months is considered to be a sufficient period for postoperative contraception. The mode of delivery depends on the individual case, though cesarean section is recommended.
