The PUL rate will probably decrease and the location of pregnancies can be diagnosed more correctly with the availability of higher resolution ultrasonography equipment ( 5). The reported rate of PUL among women attending early pregnancy units varies between 5 and 42% in the literature depending on the presence of experienced physicians and/ or equipment ( 4). However, it is not always possible to determine the location of the pregnancy in cases of PUL since both miscarriage and ectopic pregnancy may resolve spontaneously without any treatment ( 1– 3). Surgical intervention such as uterine evacuation and laparoscopy are also used in daily practice to determine or confirm the location of pregnancy. In general, sonographic evaluation in addition to interval serum human chorionic gonadotropin (hCG) measurements is essential for determination of the location of pregnancy. It is not a final diagnosis and in a certain number of women the final diagnosis cannot be made. It should be noted that PUL does not mean an ectopic pregnancy (EP). Pregnancy of unknown location (PUL) is defined as the situation when the pregnancy test is positive but there are no signs of intrauterine pregnancy or an extrauterine pregnancy via transvaginal ultrasonography (TVUS).
