A survey of 3,000 examinations by transrectal ultrasonotomography.

As a routine examination for intrapelvic organs, transrectal ultrasonotomography was performed 3,000 times on 2,331 patients from June 1976 to February 1980. In this series, 57 patients were diagnosed as prostatic cancer by transrectal ultrasonotomography and 54 (94.7%) of them were finally diagnosed as cancer by biopsy. Three hundred twenty-six patients were diagnosed as suspected prostatic cancer, and cancer was confirmed also by biopsy in 12 (3.7%) of them. Among 1,741 patients with various prostatic diseases on whom cancer was ruled out by transrectal ultrasonotomography, there were 2 (0.1%) false-negative cancer cases.

Ultrasonic real-time guidance for percutaneous puncture.

Real-time scanning was applied to the sonically guided puncture technique. A special puncture attachment connected to the ultrasound sector scanner was developed for this purpose. A puncture needle is introduced into the scanning plane through the canal in the attachment. Excellent real-time images of both the target lesion and the needle can be clearly seen on the oscilloscope during the puncture procedure. Puncture not only for cystic structures but also for solid masses can be made easily and safely by this new technique. Successful applications of the technique have been carried out for renal cyst puncture, percutaneous antegrade pyelography, percutaneous nephrostomy, percutaneous renal biopsy, and perineal prostatic biopsy.
