The aim of this study was to determine the relationship between endometrial thickness measured by transvaginal ultrasound and response rate to the treatment of ectopic pregnancy with single-dose intramuscular methotrexate. Material and Method: This cross-sectional study was conducted in Imam Reza Hospital, in Kermanshah, and included 63 patients with βHCG greater than or equal to 1200 mIU/mL and without ultrasonography evidence of intrauterine gestational sac. Also patients with constant βHCG level or increased levels of less than 50% within 48 hours were regarded as cases of ectopic pregnancy. Then endometrial thickness was measured. Methotrexate 50 mg/m2 was administered intramuscularly. βHCG titers were measured 4 and 7 days after treatment. Using SPSS 21 software, data were analyzed by statistical tests. Result: We achieved a treatment success of 82.5% with single dose intramuscular methotrexate. Age and size of mass had no relationship with endometrial thickness (p>0.05). However, there was a correlation between endometrial thickness and βHCG titer (p %> http://sjku.muk.ac.ir/article-1-1550-en.pdf %P 77-83 %& 77 %!
