Extramammary Paget's disease is a rare malignant disease associated with underlying adenocarcinoma, or not. Two cases with a unique clinical presentation are described and we wish to call attention to the malignant potential of chronic scaly and erythematous lesions of perianal and genital area.

Byars approach for the repair of hypospadias is simple, sound and has reported the lowest incidence of fistula formation. This procedure has been used in the Department of Urology, College of Medicine, Kyung-pook National University during the last 3 years. During the period, a clinical observation was made on 7 hypospadias patients who had received the 2 stage operation(resection of chordee and uerthroplasty) using Byars procedure. Infection of surgical wound was the most frequent complication, however, fistula formations did not occur in any case. The urinary stream and the states of erection were good in all cases.

The exact analysis of urinary calculi is very important to study of the etiology of calculus formation, prevention of recurrence and medical treatment. Compared with all the other method, the infrared spectroscopic analysis furnished a permanent record in a very short time. And it is ideal method for qualitative identification and semiquantitative estimation of small fractions of calculi by simple procedure rapidly. A retrospective review of stone analysis by infrared spectroscopy, with KBr tablet method was performed in 105 cases of 219 urinary stone patients, who had been admitted to the Fatima Hospital from May, 1980 to December, 1983. And the following results were obtained 1. Mixed calculus is more than single calculus(1 : 1.56) . The most common type of calculi is calcium oxalatetribasic calcium phosphate (47.6%) . And the most common type of single calculi is calcium oxalate (29.5%) . 2. The most common type of component is calcium oxalate (55.6%) 3. Calcium oxalate-tribasic calcium phosphate is the most common type in the renal (46.2%) and the ureteral stones (53%) . But in the bladder stones, magnesium ammonium phosphate is the most ( 33.3%). 4. Among the 10 laminated stones, 4 cases contain the different components in nucleus and outermost layer 5. Pyuria is observed in 48.6% of all urinary stone patients, in 32.3% of calcium oxalate stone and in more than 80% of magnesium ammonium phosphate stone. 6. Calcium oxalate stone is most common in the age of 20, calcium oxalate-tribasic calcium phosphate stone are in the age of 20 & 30, and magnesium ammonium phosphate stone is above the age of 40.

Reported results of HCG treatment for cryptorchism are quite variable because many factors may influence the success of the therapy. It is possible that the anatomic stratification introduces an element of selection bias into the data. 12 cases of extracanalicularly located testis were treated with HCG from December 1988 year to June 1990 year. Five of the 12 cases were cosmetically satisfactory. 3 became retractile testis which is disturbing in all that could be treated successfully but could not be satisfactory from the cosmetic point of view. Apparent hernial sac developed in 4 cases who were clinically inapparent before initiation of the hormonal therapy.

Cushing's syndrome refers to a clinical pictures that develops in a patient who are exposed to excess quantities of cortisol like substances. A case of Cushing's syndrome in 62-year-old man who was followed by a Nelson's syndrome after bilateral adrenalectomy is presented with brief review of literatures.

The exact analysis of urinary calculi is very important to study of the etiology of calculus formation, prevention of recurrence and medical treatment. X-ray diffraction method is a newer approach to the analysis of urinary calculi. This method was recommended due to speed, accuracy and convenience. We have analyzed 32 urinary calculi by X-ray diffraction method. The following results were obtained. 1. Mixed calculus ie slight more than single calculus. (1:1.46) 2. The most common type of calculi is hydroxyapatite + calcium oxalate. (56.3%) 3. In the calcium oxalate. mixed calculi with calcium oxalate monohydrate and calcium oxalate dihydrate are more than pure calcium oxalate monohydrate. (1:4.5) 4. The common type of calculi in the kidney is calcium oxalate and calcium oxalate + hydroxyapatite in the ureter. 5. Percentage of urinary infection is 37.8% in all patients who have urinary calculi.

Ultrasound is effective in evaluating pathologic entities of renal and bladder diseases. The advantage of the ultrasound scanning is no harmful, not need preparation, more comfortable and cheaper than other diagnostic methods with relative high diagnostic accuracy. Also ultrasound seems good primary screening test with I.V.P. in urologic diseases. So we made a brief clinical observation and reported with review of literature.

Diverticulum of the female urethra was not considered a rare lesion. but calculus formation within a female urethral diverticulum was still relatively uncommon. We treated a case of urethral diverticulum combined with multiple stones in female, and reported with review of literatures.

A total 49 strains of Escherichia coli suspected of causative organisms of urinary tract infection were isolated and studies for several properties related to the virulence markers of organisms. Urinary isolates (42.9%) showed higher frequency of mannose resistant hemaglutination (MRHA) with human erythrocytes (O type, Rh+) than stool isolates (13.3%) as a control group. Fifteen strains (30.6%) of urinary isolates and 2 (l3.3%) of stool isolates showed hemolysis on blood agar plate. Fourteen strains (28.6%) of urinary isolates and 5 (33.3%) of stool isolates produced colicin. Twelve strains (52.5%) among 23 strains of positive MRHA reaction and 5 (12.2%) of 41 non-MRHA strains found to be hemolytic effect but the frequency of transferable antimicrobial resistance of non MRHA strains was greater than that of MRHA strains. Three properties of hemaglutination, hemolysis, and colicin production were not transferred to recipient E. coli ML 14lO and/or RG 488 by conjugation whereas the antimicrobial resistance were transferred. There was not any significant difference of the minimal inhibitory concentration of 11 drugs between both groups of hemaglutinating and non-hemaglutinating strains. * A thesis submitted to the Committee of the Graduate School of Kyung Pook National University in partial fulfillment of the requirements for the degree of Master of Medical Science in June 1985.
