The efficacy and occurrence of adverse effects after two forms of treatment were compared in 111 patients with biliary colic and radiolucent gallstones in this prospective, nonrandomized study. Fifty-four patients received extracorporeal shock-wave lithotripsy (ESL) plus ursodiol, and 57 patients received ursodiol alone. Among patients with a single stone… (More)
Early recognition of pseudocyst formation in pancreatitis has been a very important contribution of diagnostic ultrasound. Furthermore, haemorrhage or abscess formation, an additional complication, can also be suspected by this diagnostic modality. False aneurysm formation of a larger, neighbouring artery is not easily recognized by ultrasound. It is for… (More)
We have described a case in which the gallbladder was catheterized by the Seldinger technic, using ultrasonic guidance. The biliary tree was flushed until clear and free passage of bile into the duodenum occurred. Thick inspissated bile can cause intrinsic echoes in the gallbladder that can be mistaken for gallstones.
With recent advances in ultrasound technology, concomitant improvement in sonographic techniques have been required. Sonographic scanning in coronal orientation, both in transverse but especially in longitudinal direction, has demonstrated a number of advantages over the routine transverse and sagittal scans. Closer correlation with functional anatomy of… (More)
Coronal renal imaging with ultrasound has a number of advantages over other routine scanning orientations in nephrosonography. In a series of 214 patients coronal transverse but especially longitudinal orientation was found to be superior to other scanning methods. The main advantages were: differentiation between renal cysts and hydronephrosis as well as… (More)
