title: Three-contrasts method: an ultrasound technique for monitoring transcervical operations.
abstract: The "three-contrasts method" of ultrasonography is designed to monitor transcervical operations for submucous uterine myomas and uterine septa when a pediatric urologic resectoscope is used. This monitoring method has proved more effective than concomitant laparoscopy. The pediatric resectoscope can also be used efficiently for diagnostic and therapeutic purposes without dilating the cervical canal.
