[Value of ultrasonography in the diagnosis of bladder tumors].
The authors have compared the value of transabdominal, transrectal and intravesical ultrasonography in 100 patients with carcinoma of the bladder. They have also compared the pathological stage, determined at operation or post mortem, with the "ultrasound" stage. Transabdominal examination resulted in agreement in 61% cases, transrectal 69% and intravesical in 92%. In the authors' opinion, transabdominal ultrasonography is suitable for general orientation. It can determine the size and position of the tumour. Transrectal examination is particularly valuable if, for any reason, it is impossible to perform cystoscopy. It is also valuable for the examination of tumours localised at the bladder base. Intravesical sonography demonstrated the tumour in every case. During this examination, changes in the elasticity and distensibility of the bladder due to tumour and changes in the bladder volume can be determined. Intravesical ultrasonography carried out at the same time as cystoscopy is a rapid and highly practical procedure, which ideally supplements cystoscopy. At present it is the best method for demonstrating infiltration of the bladder wall.
