PURPOSE: We assessed the accuracy of a portable ultrasound device (BladderScan(TM) BVI 3000) used to measure the postvoid residual urine volume (PVR). MATERIALS AND METHODS: We prospectively measured the volume of residual urine in 160 patients with lower urinary tract symptoms between August 2000 and April 2001. After voiding, PVR measurements were performed immediately using ultrasound bladder scanning, followed by Nelaton catheterization, with the patient was in the supine position, and compared the results of the two techniques. RESULTS: The ultrasound bladder scanning correlated well with the catheterization for measuring the PVR (r=0.946). The ultrasound bladder scanning had a sensitivity and specificity of 95.4 and 100%, respectively, in detecting a PVR>or=100ml, and 83.4 and 91.5%, respectively, in cases where the PVR was less than 50ml. A multiple regression analysis, and a two sample t-test, showed that the difference was not related to: age, sex, weight, height, body mass index (BMI) or related diseases (p>0.05). Age, weight, height, BMI were not significant variables when comparing the sexes (p>0.05). There was a significant difference in patient's satisfaction and the required time of the procedure between bladder scanning and catheterization (p<0.01). CONCLUSIONS: Portable ultrasound bladder scanning is quick, easy to use, non-invasive, readily repeatable, and specific for determining the PVR. Therefore, portable ultrasound bladder scanning can be used as an alternative to catheterization in the determination of residual urine volume.

Presented a 39 year old man of cerebral malaria and pertinent literature were reviewed briefly. The patient was admitted because of fever and drowsy mental state. On admission, there were mild icteric sclerae and hepatomegaly. Brain C-T scan was normal. The cerebrospinal fluid study showed increased pressure (280 mmH20), and protein content (150 mg/dl) with mild pleocytosis. The EEG revealed diffuse delta waves throughout the head. At the 3rd hospital day, the patient was rapidly deteriorated to comatous state showing marked hyperbilirubinemia, thrombocytopenia and bleeding tendency and expired. Numerous plasmodium falciparum parasites were revealed in the peripheral blood smear.

PURPOSE: Improvement in the prognosis of multiple primary malignant neoplasm may be attained by early discovery and awareness of the secondary tumor. This study aimed to determine the characteristics of multiple primary neoplasms involving the urinary tract in Korea. MATERIALS AND METHODS: Of 1,406 patients treated for urologic cancers, 76 patients with multiple primary neoplasms also involving other than the genitourinary system were analyzed. We studied the occurrence rate and distribution of tumors. RESULTS: Of the 76 cases, 33 cases were synchronous and 43 cases were metachronous. Average time interval between the diagnosis of first and second tumor was 48 months. Tumors of the gastrointestinal tract, particularly stomach cancer, among non-urologic cancers and tumors of the bladder among urologic cancers were predominantly involved followed by renal and prostate tumors. However, renal tumor was the most common urologic tumor in synchronous cancers. Eighty-one percent of the metachronous urinary tumors occurred as second tumors. CONCLUSIONS: Our present findings show that the occurrence of multiple primary neoplasms involving the urinary tract is not rare and that the incidence of organ involvement is different from the western countries.

Recurrent episodes of venoocclusive priapism have been described previously in patients who have had repeated exposure to a recognized stimulus such as intracavernosal injections of vasoactive agents, or pathologic conditions such as spinal stenosis or hematological disorders. Three patients were referred for evaluation of an unusual sequoia of an initial episode of idiopathic venoocclusive priapism, occurred with a frequency ranging from several times per month to once per year and were symptomatically disabling. We reviewed the characteristics and the possible pathophysiology of this syndrome and some therapeutic options in the management of these patients.

PURPOSE: Acute pyelonephritis (APN) is mostly caused by ascending infection. Based on clinical and experimental studies, it is known that APN is caused by bacteria that ascends from the bladder through the ureter to the renal pelvis and parenchyma. Urinary reflux, bacterial virulence factors, and decreased ureteral peristalsis are some of the causes of ascending infection. We have tried to evaluate the significance of reflux in adult uncomplicated APN. MATERIALS AND METHODS: Voiding cystourethrogram (VCUG) was performed in 71 female patients with APN who showed no structural abnormalities on either intravenous urogram or ultrasonogram from April 1998 to May 2000. VCUG was performed at cure phase (29.7+/-9.18 days, 20 patients) in the early days of the study and the date of performing VCUG was shortened gradually to resolved phase (13.8+/-2.13 days, 10 patients), subacute phase (6.60+/-1.84 days, 10 patients), and acute phase (2.42+/-0.51 days, 31 patients). RESULTS: There were only 2 (2.8%) cases with vesicoureteral reflux among 71 female patients with uncomplicated APN. 1 ipsilateral grade 2 reflux was found among the 20 patients who underwent VCUG at cure phase. 1 case with ipsilateral grade 1 reflux was found at resolved phase. Reflux was not found in the groups where study was performed at subacute and acute phase. The cause of infection was found to be E. coli (55 patients, 77.5%), Enterococcus faecalis (3 patients, 4.2%), Klebsiella pneumoniae (2 patients, 2.8%), and S. aureus (1 patients, 1.4%). CONCLUSIONS: These results suggest that reflux may not be a significant factor causing ascending infection that leads to APN. More study on the pathophysiology of ascending infection to the upper urinary tract is warranted.

Focal nodular hyperplasia (FNH) is a rare, benign hepatic tumor which was usually discovered incidentally by imaging procedure performed for some other reasons. FNH is typically asymptomatic and, it seldom bleeds. There is no evidence to support any relation with primary liver cancer. Accordingly, the preferred management is conservative, and excision is reserved for large symptomatic and complicated lesion, or when the diagnosis remains uncertain. Although many cases of FNH has been described to date in the other countries, only four cases of FNH has been reported in Korean literature. In the present report we describe a 7 cm sized asymptomatic lesion of FNH in a 23-year-old woman, that was disclosed by various kinds of imaging procedure. The left lateral segmentectomy was performed. The mass was firm and showed areas of localized growth of mature hepatocytes and septal fibrosis accompanied with marginal ductal proliferation, consistent with FNH. It also displayed an incomplete stellate architectual configration consisted of a central fibrous scar.
