Color Doppler flow imaging has been used as a supplementum to the ultrasound guidance in 16 renal biopsies, 8 nephrostomies and 6 renal cyst punctures. Puncture of intrarenal vessels could be avoided and fluid flow as in aspiration of cyst fluid or urine and drug injection could be monitored. No complications occurred in this series. Although this new(More)
A 71-year-old man was admitted with complaints of right lower quadrant pain and abdominal fullness. Barium enema and computed tomography (CT) scan demonstrated a tumor in the terminal ileum. There was no enlargement of superficial lymph nodes. Colonofiberscopy revealed a narrowing of the terminal ileum and biopsy specimens showed evidence of B-cell(More)

Cystometry may be considered as a stretch test for the bladder wall. In the 1st report, it was stated that the properties of the bladder were well explained as a visco-elastic model proposed by Glantz and a formula for the stress-strain curve was proposed. In this 2nd report, another formula representing theoretical cystometrogram derived from the former(More)

A stretch test in vivo for living material was newly developed and applied to the dog bladder. The stress-strain curve of the bladder was speed-dependent and with hysteresis. The mechanical properties of the bladder in vivo was essentially viscoelastic. The stress-strain curve of a normal living bladder was downward convex and rose very slowly. On the other(More)

Cancer nodules in early prostate cancer are mostly visualized as hypoechoic lesions on ultrasonogram. In a small number of prostate cancers, the cancer nodule is isoechoic and difficult to visualize. In advanced prostate cancer, the prostate is enlarged asymmetrically and deformed. The internal echo pattern of the prostate with advanced prostate cancer has(More)
During systemic hyperthermia (42 degrees C), depression of ST segments or T wave changes in the left precordial leads were noticed in 56% of patients, and 29% of cases showed right bundle branch block. Supraventricular tachycardia was found in 26% and temporary deviation of mean frontal vector to the left axis was observed in 15%. These changes disappeared(More)
