Diagnostic accuracy and its limitations in prostatic cancer by means of transrectal ultrasonotomography.

We evaluated transrectal ultrasonotomography performed on 97 cases of prostatic cancer and obtained the following results: Transrectal ultrasonotomography was far more accurate in the diagnosis and staging of prostatic cancer than palpation. However, diagnosis is rarely difficult in cases with a symmetric and non-deformed prostatic shape. Though transrectal ultrasonotomography is very sensitive in the detection of extracapsular cancer infiltration, under-estimation of staging may still occur in some instances.

The effect of estramustine phosphate on prostatic cancer estimated by transrectal ultrasonotomography.

Transrectal ultrasonotomography was performed in 44 patients with prostatic cancer before, during, and after estramustine phosphate (Estracyt) administration. In 75.7% of 37 previously untreated patients, the deformity of the horizontal section of the prostate with prostatic cancer was corrected considerably, while in 89.2%, prostatic weight was remarkably reduced. In 57.1% of seven previously treated patients, appreciable changes were also observed in the shape and weight of the prostate. We concluded that estramustine phosphate was effective not only for untreated prostatic cancer, but also, at least in some degree, for relapsed cases.

A clustering of prostatic cancer in an area with many manganese mines.

In the process of our mass screening trials for prostatic diseases, a significant clustering of prostatic cancer in a town in the suburbs of Kyoto was detected. Upon survey a possible association was found between the locations where the patients lived and the manganese ore deposits distributed in the town.

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.

Ultrasonic diagnosis of intrascrotal contents.

Our brief experience of the use of ultrasonography and ultrasonic Doppler method for the diagnosis of intrascrotal contents were described. Five cases of testicular tumor, two cases of hydrocele and one case of epididymal tuberculosis were successfully diagnosed by ultrasonography. Only one case of chronic inflammation was misdiagnosed as a testicular tumor. Two cases of testicular torsion and two cases of acute epididymitis were easily differentiated by the ultrasonic Doppler method. We suggest that this is the most reliable technique for differentiation between these two diseases.

Puncture of the seminal vesicles guided by a transrectal real-time linear scanner.

An interventional technique using a transrectal real-time linear scanner has been applied to the transperineal puncture of the seminal vesicles in 143 patients. The composition of this group was as follows: seminal vesiculitis, 98; hemospermia, 20; and prostatic cancer, 25. The aspiration of fluid and the injection of antibiotics and/or steroid drugs into the vesicles were performed for the diagnosis and treatment of seminal vesiculitis and hemospermia. Clinical symptoms improved in 62% of the former and in 50% of the latter cases. Cancer cells were detected in aspirated vesicular fluid in 7 out of 17 cases with prostatic cancer. A remarkable improvement in the diagnosis of prostatic cancer invasion into the seminal vesicles can be expected from this new diagnostic procedure.

Sexual behavior in Japanese males relating to area occupation, smoking, drinking and eating habits.

Sexual behavior was evaluated in 2228 Japanese males aged from 42 to 94 years of age. They were interviewed individually by well-trained urologists, when mass screening for prostatic diseases was performed. Concerning the first sexual intercourse early could be distinguished by the same characteristics. The age of impotence in office workers and daily smokers was significantly young. Compared with American males in the literature, the characteristic features of sexual behavior in Japanese males were as follows; 1) The age of first sexual intercourse was more than 7 years after that of American males, 2) The frequency of sexual intercourse before 40 years of age was higher, but that after 40 years of age was less, than that of American males, 3) The age at which sexual intercourse was no longer practiced was almost the same in the two countries.
