Two cases of ureteral fibrous polyp showing serpiginous filling defect on IVP are presented with characteristic radiologic features; easy flow of contrast medium around polyp. Prolapsed polyp in urinary bladder, and less ureteral obstruction or renal damage than in epithelial lesions. These rediologic findings enable to differentiation of ureteral fibrous polyps from malignant tumor, which is helpful for determining therapeutic approach.

PURPOSE: To evaluate the findings and the role of CT in plexiform neuro-fibromatosis of the mediastinum. MATERIALS AND METHODS: We retropectively reviewed the CT scans of five patients with plexiform neurofibromatosis of the mediastinum. The CT scans were reviewed with attention to the distribution of the lesions, appearance and attenuation of mediastinal lesions, enhancement pattern after intravenous contrast infusion and associated findingssuch as intercostal neurofibroma. RESULTS: In all five patients CT scans demonstrated fusiform low attenuated masses which were oriented longitudinally and extended over multiple contiguous scans along the distribution of major mediastinal nerves. In four patients, mediastinal lesions appeared infiltrative, obliterating adjacent mediastinal fat plane. One patient had well defined fusiform masses along the major mediastinal nerves. Postcontrast enhanced CT scans revealed slight central enhancement in two patient and no contrast enhancement in three patients. Associated findings such as neurofibromas of intercostal nerves and sympathetic trunk, or subcutaneous neurofibromas were detected on CTscans in all five patients. CONCLUSION: Characteristic CT findings of low attenuation masses along the major mediastinal nerves are helpful to differentiate plexiform neurofibromatosis from mediastinal lymphadenopathy and to prevent from misreading as a malignant disease.

The need for film recording in endoscopic practice is important with the present demand for documentation and teaching (legal problem). The electronic endoscopy which has a very small charge coupled device (CCD) at the distal end of an endoscope yields several times more resolving power than conventional optical endoscopes. However the system has not been utilized in Urologic field because there has not enough space for CCD at the end of the telescope comparing to the endoscope in Gastroenterology field. However the video converter with CCD could be adapted to the eyepiece of the telescope, and the automatic monitor photo unit (CVP 600, SAMSUNG, KOREA), video system and monitor were used for imaging, which is so called Urologic Video Information System (UV1S). The image processing was done by instantaneous system (CCD color camera, EC-202 II, ELMO, Japan) with conventional optical light source. From September 1992 to August 1996, we did cystoscopic examination with CCD in 1079 cases.

PURPOSE: Many articles have proposed that osteonecrosis of the femoral head (ONFH) is caused by fat embolism or intravascular coagulation linked to hyperlipidemia. To determine whether hyperlipidemia is an associated factor for ONFH, serum lipid levels were measured. MATERIALS AND METHODS: Nighty-eight patients presenting with ONFH and 110 controls were investigated. We compared the average value of serum lipid levels and the incidence of hyperlipidemia of the two groups. RESULTS: ONFH group showed generalized increase in lipid level and statistically significant difference in the average value of total cholesterol (P=0.0001), HDL-cholesterol (P=0.0261) and phospholipid (P=0.0465) compared with the control. The incidence of hyperlipidemia of the two groups showed statistically significant difference in HDL-cholesterol (P=0.019) and triglyceride (P=0.024). CONCLUSION: Hyperlipidemia seems to be associated with pathogenesis of ONFH. We speculated that hyperlipidemia might be a contributing factor of ONFH. Hyperlipidemia may play a role as a triggering factor in the pathogenetic process that results in osteonecrosis. However, it can not be ruled out that secondary hyperlipidemia might be a finding following ONFH.
