[Functioning ovarian cysts in patients with and without tubal sterilization]
1Departamento Radiodiagnóstico, Hospital General de Zona 6, Instituto Mexicano del Seguro Social.
Purpose Of The Study:
To determine by ultrasound, the frequency of function ovary cysts (FOC) in patients with surgical sterilization by bilateral tubal obstruction (BTO) compare to a similar group without previous surgery.
Method And Materials:
Between August '96 and September 97, 290 patients were divided in 2 groups of 145 each. The first group were patients with BTO and the second, without. Each group was divided in 8 equal subgroups.
Results:
In the patients with FOC, 35 cases (24.1%) had BTO compared to 18 (12.4%) from the group without the previous surgery. In both groups a parallel increase was detected between the 36-45 years there aren't variation in the FOE curves relates to the ratio.
Conclusions:
The presence of FOB is significantly greater in patients with BTO than in those without this antecedent. The age factor influence by itself in a uniform way, in both groups and its assume to alterations due function declination. The ratio seem to have influence in the apparition of FOC.
