Automated water-path ultrasonic examination of scrotum.

A new method of examining the scrotum by ultrasound with an automated water-path scanner is described. This method allows immobility of the scrotum in a more acceptable and painless way than in contact scanning methods. Panoramic scans of the entire scrotum and precision tomographic plane placement are advantages over conventional techniques. A description of normal scrotal anatomy includes the mediastinum of the testis, an important scrotal landmark. Representative cases of benign and malignant scrotal disease are presented to emphasize the utility of water-path scanning.
