Two cases of emphysematous pyelonephritis

Emphysematous pyelonephritis is rare but freuently fatal complication of renal parenchymal infection, mostcommonly occurs in diabetic patients and is often associated with urinary obstruction, prior urologicalabnormality or infection. From 1898 to 1984 , about 50 cases of empysematous pyelonephritis have been reporteduniversally. The diaignosis of emphysematous pyelonephritis can be made only roentgenographically. In the last 2years, we have had two cases of emphysematous pyelonephritis at our hospital. It is our purpose to report twopatients who have survived wtih a brief review of the previous literature.

CT findings of epidemic encephalitis in acute stage

Although the incidence of epidemic encephalitis has decreased mardekly nowadays, sporadic cases are stillobserved in Korea. In this study, CT findings of 17 patients with clinically and serologically proven epidemicencephalitis were analized. In principle, CT scans were done at the acute and subacute stage, whithin 20 days fromonset. The results were follows; 1. Of all 17 patients with CT scan, normal scan were demonstrated in 3 cases andabnormal scans in 14 cases. 2. The abnormal CT findings were ; area of low density in 9 cases, brain edema in 7cases, nodular and gyral contrast enhancement in 3 cases, central brain atrophy in 3 cases and hemorrhagic highdensity in 2 cases in order of frequency. 3. The CT findings, according to date of CT scan from onset, were; brainedema and are of low density within 10 days from onset, normal or central brain atrophy between 11 days and 20days, are of hemorrhagic high density and contrast enhanced lesions at both stage. 4. The locational distributionswere; thalamus and cerebral white matter in 7 cases respectively, basal ganglia in 5 cases, cerebral cortex in 4cases and septum pellucidum in 1 case in order of frequency.

A clinical and radiological observation on urolithiasis

A clinical and radiological observation was mde on 167 cases of urolithiasis among the number of 150 patientsduring 1 year and 6 months from June, 1981 to Nov. 1982. The results were summerized as follows. 1. There were 101man and 49 women, a ratio of 2:1. The ages of the patients ranged from 2 to 74 years, showing the highestincidence in 31 to 60 years(68.1%). 2. Locational distributions of urolithiasis were 80 cases (47.9%) in theureter, 66 cases(39.5%) in the kidney, 11 cases (6.5%) in the urethra and 10 cases (5.9%) in the bladder. 3. Amongthe 66 cases of renal stone, pelvis stone was 55 cases (83.3%) with staghorn types in 23 cases(34.8%), andcalyceal stone was 11 cases(16.6%). 4. The location of ureteral stone was 47.5% in lower, 40% in upper ureter and12.5% in mid-ureter. 5. The location of urethra stone was 82% in the anterior urethra and 18% in the posteriorurethra. 6. The chief complain of urolithiasis was flank pain in 59.2%, gross hematuria in 20.3%, renal colic in13.1% ,dysuria in 8.3%, nausea and vomiting in 4.7%, and sudden stoppage of urine stream in 3.5%. 7. Onurinalysis, gross hematuria was found in 54.4%, pyuria in 28.7%, bacteriuria in 23.3%, microscopic hematuria in18.5% and normal in 7.1%. 8. The size of urinary stone was 0.6-2.0cm in length in 105 cases(62.8%). 9. On I.V.P.study of renal stones(66 cases), mild and moderate hydronephrotic changes were detected in38 kidneys(57.5%), andthe relationsip between the urinary stasis and renal stone size was relatively good. 10. On I.V.P. study ofureteral stones(80cases), mild to severe hydronephrotic changes were detected in 64 kidneys(80%). 11. On K.U.B.film, paralytic ileus was found in 25 cases (14.9%). 12. Among the urinary stones, the radiolucent stones weredetected in 8 cases (4.7%). 13. Urinary stones diappeared in 11 cases (6.5%) spontaneously or medical treatment.
