[Ultrasonographic evaluation of bladder volume].

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.
