[Transvaginal ultrasonography in 27 confirmed cases of ectopic pregnancy]. / Hallazgos a la ultrasonografía transvaginal en 27 casos comprobados de embarazo ectópico.

Twenty seven patients having Ectopic Pregnancies were studied prospectively with transvaginal sonography. Ten of them were treated surgically, thirteen with injection of methotrexate and four with expectant management. Ultrasound images were well correlated with clinics, surgical findings and pathology. We believe that the ultrasound image known as "tubal ring" is highly suggesting of early ectopic pregnancy. Since early detection is associated with conservative surgery, expectant management or treatment with methotrexate, and consequently to a better reproductive future, we consider that transvaginal sonography is a reliable method that must be added to traditional ones, in the ectopic pregnancy management.

[The treatment of ectopic pregnancy with local and intramuscular methotrexate or expectant management]. / Tratamiento del embarazo ectópico con metotrexato, local, intramuscular o manejo expectante.

Ten patients with ectopic pregnancy, probably non complicated, diagnosed by transvaginal sonography and serial determinations of subunit B of human chorionic gonadotrophin, were treated with a single injection of methotrexate intraovular (5 cases), intramuscular (3 cases) or with expectant management. We obtained clinical resolution and undetectable hormone levels in seven patients and three underwent additional surgery.

[Ultrasonographic evaluation of bladder volume]. / Evaluación ultrasonográfica del volumen vesical.

Twelve women of gynecologic dispensary of Hospital del Salvador are studied, making measurements of several ultrasound parameters of urinary bladder (diameters and perimeters), with known volumes instilled through catheterization. The results are mathematically and statistically studied with computer getting a formula of easy management to obtain the vesical volume. This formula is advantageously compared with others of literature. Advantages of ultrasound measurement of vesical volume are stressed in patients with uro-gynecologic pathology.
