BACKGROUND: Urography(IVU) is considered the best first investigation in patient with suspected urinary calculi, but recently ultrasonography(USG), combined with a plain film of the abdomen, has been suggested as an alternative. METHODS: We undertaken study to see if this approch can be used in emergency patients and outpatients by radiologists with different amounts of ultrasound experence. Some 192 patients with suspected urinary colic presenting to Koo Hospital Emergency Department and Youngnam Universith Hospital outward Department(IM, URO, FM) over 12-month period were studied. They had a plain abdominal film(KUB) and USG examination of the kidney, ureter, bladder following hydration and subsequently underwent IVU. Of these, 22 patients passed a stone before their IVU. The data analysis was performed on the remaining 170 patients. Urography was used as the gold standard. RESULTS: Some 170 patients subsequently underwent IVU at a mean interval of 1.8 days after the ultrasound examination. In 91 of 170 patients the IVU was positive. In 97 of 170 patients the combination of JUB plus USG was positive, leaving three false negative KUB plus USG. Thus the sensitivity of KUB plus USG was 97%, specificity was 89%, positive predictive value was 91%, and negative predictive value was 96%. CONCLUSIONS: Our findings in this study suggest that in the hydrated patient the combination of KUB plus US is a very sensitive and relative specific screening test. Because of the high negative predictive value of KUB plus US, urography is not likely to be helpful when KUB plus US are negative. Urography is indicated only if KUB plus US findings are equivocal or if intervention is necessa.ry.

OBJECTIVES: There have been several studies documenting the changing level of the conus throughout infancy and childhood, but there is only a little detailed study that documents the range of conus positions in a living adult population, especially in Korean, without spinal deformity. METHODS: we made a sequential study of magnetic resonance images of the lumbar spine to determine the variation in position of the conus medullaris in 650 living korean adults population without spinal deformity who checked MRI to identify the cause of low back pain. The study population consisted of patients over the age of 16 years. A T1-weighted, midline, sagittal image was reviewed for identifying the postion of conus. This location was recorded in relation to the upper, middle, or lower third of the adjacent vertebral body or the adjacent intervertebral disc. RESULTS: The study group consisted of 305 men(47%) and 345 women(53%) with a mean age 45.9 years(range, 16-79 years). The conus existed commonly at the middle third of L1(131cases, 20.2%), at the L1-2 intervertebral space(129cases, 19.8%), and the lower third of L1(123cases, 18.9%). The mean position of conus was the lower third of L1(range, middle third of T12 to middle third of L3). Conclusions:The mean position of conus was at the lower third of L1(range, middle third of T12 to middle third of L3). This results was same as that of foreign study. Our results of living korean adult population could allow for safe clinical procedures such as lumbar puncture, spinal anesthesia, and help to explain the differences among observed neurologic injuries from fracture-dislocation at the thoracolumbar junction.

A 16-year old male patient visited the hospital complaining of inguinal pain and internal snapping of right hip joint. In physical examination, the patient was presumed to be diagnosed femoroacetabular impingement (FAI) and acetabular labral tear. In radiologic evaluation, FAI and acetabular labral tear were identified and bony tumor associated with internal snapping was found on the posteromedial portion of the femoral neck. Despite of conservative treatment, there was no symptomatic improvement. So arthroscopic labral repair, osteoplasty and resection of bony tumor were performed. The tumor was pathologically diagnosed as osteochondroma through biopsy and all symptoms improved after surgery. There was no recurrence, complication or abnormal finding during 1 year follow up. Osteochondroma located at posteromedial portion of femoral neck can be a cause of internal snapping hip and although technical demands are challenging, arthroscopic resection can be a good treatment option.

Ovarian remnant syndrome is a rare condition which develops when functional ovarian tissue is left in situ after intended bilateral oophorectomy. It produces clinically significant syndrome, namely chronic pelvic pain and dysmenorrhea. Although the true incidence of this syndrome is unknown, an apprant increase in incidence has been reported. We have experienced a case of ovarian remnant syndrome showing chronic pelvic pain and palpable abdominal mass after difficult gynecologic operation. So, we report this case with a brief review of literatures.
