Abstract


An ultrasonic scanner in the field of urology is described that can be used for transurethral as well as for transrectal scanning of the bladder and prostate. The bladder was visualized best by transurethral scanning, while the rectal approach was preferable for examination of the prostate. Transurethral ultrasonography was performed in 7 patients with bladder cancer. Transrectal ultrasonography was performed in 21 controls and 41 patients with prostatic disease.
The following results were obtained:

1. Diagnostic accuracy of the staging of transurethral ultrasonography was 85.7% in bladder cancer.

2. The average values of maximum anterioposterior, superio-inferior and transverse diameter. obtained from ultrasonogram were 2.43+-0.29cm, 3.27+-0.41cm, 4.07+-0.91cm in control group ;3.11+- 0.6lcm, 4.16+-0.66 cm, 4.71+-0.76cm in B.P.H.; 3.65+-0.46cm, 4.88+-0.23cm, 5.98+-0.18cm in prostatic cancer.

3. Diagnostic accuracy of transrectal ultrasonography was 93% in B.P.H. and 80% in prostatic cancer.

4. Transurethral ultrasonography enabled us to determine the degree of tumor invasion of the bladder wall and was useful to help select appropriate therapy. Transrectal ultrasonography has proved especially in estimating prostatic size and in detecting pathology.
