A clinical study was made on 45 patients who were treated with intravesical chemotherapy after transurethral resection of bladder under the diagnosis of superficial bladder tumor in the Depart. of Urology, Chungnam University Hospital, during the period from Feb. 1986 to Nov. 1991. The results were as follows. 1. The patient's male : female ratio was 38 : 7(total 45 cases) and the average age was 55 years. The average followup periods were 16.9months. 2. Diagnostic value on IVP in superficial bladder tumor was related with tumor size, which all cases above 3cm was detected on IVP. 3. There was close relation between grade and invasion of lamina propria in superficial bladder tumor. There was no invasion of lamina propria in grade I tumor, but in all cases of grade Ⅲ tumor invasion was noted. 4. The recurrence rate was closely related with invasion of lamina prorpia and tumor size. 5. There were no significant statistical differences in the recurrence rate among the each group in intravesical instillation of thiotepa, adriamycin or BCG on the purpose of prevention of recurrence rate after TUR-B under diagnosis of superficial bladder tumor. But recurrence rate in 6months followup was 10.0% in BCG treated group, 19.0%, in adriamycin treated group and 28.6% in thiotepa treated group. 6. The complications in BCG treated group identified included bladder irritation symptoms in 60%, gross hematuria in 50%, skin rash in 20%. dvsuria, back pain and urticaria in each 10% and admission in 10%. In adriamycin treated group baldder irritation symptoms in 14.3, gross hematuria and skin rash in each 10.5% and dysuria and urticaria in each 4.7%. In thiotepa treated group bladder irritation symptoms in 28.6% and skin rash in 7.1%.

This study is based on the investigation of the actual conditions of management and the comparative analysis of related actions of parks and green spaces in local autonomous entities (six cities). For conducting this research, questionnaires were used. The research findings are summarized as follows and they could be used for improving the quality of management systems of urban parks and green spaces. Meanwhile, this study's findings are in brief as following; in case of employment and promotion, research the new member of forest section during 3 years(1992-1994) in order to Seoul 57 persons(38.4%), Busan 45 and KwangJu 4 persons(2.7%). DaeGu and DaeJeon's employment had equalbalance according to the local. Also, application had an unbalance of the personnel structure about position balance so that's why so many low position worker engagement. In case of educational training and consideration of professional, member's professional improvement required re-education and have to re-set up the curriculum that all self government groups depend on office of forestry except Seoul city. In case of consciousness tendency analysis, member's working desire requirement(4.60), professional worker for the park and green administration requirement(4.60) were showed so high. Efficiency of position management(2.39), Structure discrepancy of personnel management system(2.45), functional worker shortage of parks and green space(2.40) and etc. were showed low. In evaluative model analysis, for the efficiency of managing system, member's work desire, proper educational training, discrepancy of personnel management system discrepancy, professional worker required for the park and green space, working circumstance, personnel evaluation according to task achievement via educational training course relatively.

A clinical study was made or 93 patients with uethral injury treated in the Depart. of Urology, Chungnam University Hospital, during the period from Jan. 1980 to Oct. 1990. The results were as follows 1. Of 262 patients with genitourinary trauma among 3608 urologic inpatients during the period, 93 patients sustained urethral injury. 2. The age ranged from 2 to 84 with average 38 years. 3. The most common cause of urethral injury was traffic accident (36.6%) which is followed by straddle injury(34.4%), blunt trauma(10.7%), fall down(8.6%), iatrogenic(7.5%), penile fracture(1.1%) and laceration(1.1%) in decreasing order. 4. Most of cases caused by traffic accident were associated with pelvic bone fracture, which sustained membranous urethal injury. 5. The primary managements were suprapubic cystostomy in 46 cases, urethral catheter only in 17 cases, urethral realignment in 13 cases and the secondary operations were urethroplasty only in 21 cases, urethroplsty with VIU(visual internal urethrotomy) in 13 cases and VIU only in 18 cases. 6. Of the 46 cases treated with primary cystostomy, urethral stricture developed in 33 cases(71.7%), impotence in 4 cases(8.7%), incontinence in 1 case(2.2%), urethrocutaneous fistula in 2 cases(4.3%), and epididymitis in 1 case(2.2%). 7. Of the 13 cases treated with primary realignment, urethral stricture developed in 7 cases(53.8%), incontinence in 1 case, urethrocutanous fistula in 1 case and epididymitis in 1 case(each 7.7%). 8. In the male posterior urethral injury, complete injury were 19 cases and partial injury were 13 cases. Of the 19 cases of complete injury, urethral stricture developed in 16 cases(84.2%), impotence in 5 cases(26.3%), incontinence in 2 cases(10.5%), urethrocutaneous fistula in 1 case and epididymitis in 1 case(each 5.3%). Of the 13 cases of partial injury, urethral stricture were developed in 11 cases(84.6%), impotence in 1 case and incontinence in 1 case(each 7.7%).

윤율로,송규상 충남대학교 의과대학 지역사회의학연구소 1992 충남의대잡지 Vol.19 No.2

Using a silver staining technique, nucleolar organizer regions(AgNORs) were identified in routinely processed paraffin sections of transitional carcinoma of baldder which were selected from the 37 patients diagnosed in the Depart. of Urology, Changnam University Hospital, during the period July 1986 to July 1992. The technique showed as follows. 1. Argyrophilic nucleolar organizer regions(AgNORs) were seen as sharply defined dark brownish dots in the almost all nuclei of tumor cells. The nuclei were stained as brownish color and cytoplasms as more light brown color. 2. The Mean scores of AgNORs were 1.07 ± 0.04 in Chronic cystitis, 1.52 ± 0.31 in Grade Ⅰ, 1.99 ± 0.04 in Grade Ⅱ, 3.21 ± 1.20 in Grade Ⅲ, 5.24 ± 1.20 in Grade Ⅳ of the transitional carcinoma of the bladder. Using Kruskal-Wallis test the mean scores of AgNORs among each group showed a statistically significant differences(P value < 0.001). 3. The mean scores of AgNORs of each stage of tumor 2.61 ± 1.44 in Stage Ⅰ, 2.56 ± 1.20 in Stage Ⅱ, 3.40 ± 1.99 in Stage Ⅲ, 3.76 ± 1.37. There was no statistical significant differences among the each group of stage(P value > 0.5). 4. No significant correlation was obtained between AgNORs and tumor size or number. 5. The well defined inverse relationship was observed between AgNORs numbers and their sizes. The numbers of AgNORs rises with decreasing differences and increasing malignancy. Thus, the standardized assessement of argyrophilic nucleolar organizer regions can be easily performed by any surgical pathology laboratory without specialized equipment and may be useful as an good indicator of proliferative activity of tumor cell or biological behavior.

수치해석을 이용한 음향장내의 압력장 해석에 관한 연구

Applying ultrasonic waves in a medium enhance the heat transfer, judging from the facts that applying ultrasonic waves to the liquid medium gives rise to areas of high and low local pressure. Therefore, in the present study, a coupled finite element-boundary element method(FE-BEM) was used to calculate the acoustic pressure in a medium. For the numerical analysis, we performed the process of finite element modeling. This modeling data was converted to the boundary element data by SVS(Structure Vibtation Simulator). SVS programmed was composed of FORTRAN language and based on a coupled FE-BEM. The results of numerical analysis reveal that acoustic pressure is increased by 60% at the ultrasonic intensity of 340W and the higher acoustic pressure distribution near two ultrasonic transducers.

새로운 기법을 이용한 요도하열의 수술

We have treated nine hypospadias patients, who were admitted from April, 1996 to November, 1966 using several modified operation techniques : plastic catheter instead of urethral stent and suprapubic diversion, preservation of urethral plate, pedicled subcutaneous tissue covering over new maden urethral tube, glandular fixation with supporting lever, and double diaper dressing. We experienced a significantly lower complication rate(11%) compared to previous techniques. So we recommend the onlay island flap urethroplasty which preserves the urethral plate in the mid and posterior hypospadias repair with above mentioned techniques.

The urethroplasties were performed on 20 patients with hypospadias who had been admitted to the Department of Urology Chungnam National University Hospital from January, 1990 to March, 1993. After chordectomy the most common type of hypospadias was penoscrotal type(9 cases,45%). And the combined anomalies were 40% and the scrotal transposition was the most common. Of the 12 one-stage urethroplasties 7 were performed as Duckett method,1 as MAGPI method, 2 as Hodgson I method,1 as Hodgson II method and 1 as augmented Duckett method. Of the 8 two-stage urethroplasties 4 underwent as modified augmented Duckett method, 1 as modified Duckett method with scrotal flap, 1 as Broadbent method, 1 as Rochet method and 1 as modified Rochet method with inguinal flap. The complication rate was 50%,in which the most common complication was urethrocutaneous fistula(7 cases,35%). The complication rates by year were 71%, 50%, 43%, 0% from 1.990 to 1993, respectively. Thus, it is thought that the advance in operation technique may be very important factor for successful operation. The methods of Duckett and augmented Duckett were used in minimal and moderate severe urethral defect and school age and modified two-staged Duckett method were performed in severe urethral defect and preschool age without significant complications. So these results suggests that the methods using dorsal inner prepuce, which is adjacent to operation field, rich blood supply,good elasticity, no contracture after surgery, cosmetic advantage and hairless, are recommended for choice of urethroplasty of hypospadias if possible.

잠복고환의 수술시기에 관한 병리학적 연구

윤율로,나용길 충남대학교 의과대학 지역사회의학연구소 1994 충남의대잡지 Vol.21 No.2

Structural and ultrastructural studies have been done in 17 cryptorchid patients who visited the Depart. of Urology, Chungnam National University Hospital from Jan., 1994 to Oct., 1994. Light microscopically, the considerable change was not evident in patients under 4 years old. For those older than four the changes were noted as follows : decreased diameter of seminiferous tubule until puberty group, thickening of basement membrane, widening of interstitial space, collagen fiber deposition in tunicapropria. vacuolization of seminiferous tubule and interstitium. These changes were more prominent in pubertal intraabdominal testis. Electromicroscopically, even when the patient was 17 months old collagenous deposition was noted in interstitial space, which is evidence of thermal stress. Also the pathological change in ultrastructure was noted in abdominal testis of a 30 month old patient, which didn't show the change microscopically. The findings of these ultrastructural changes were vacuolization of seminiferous tubule, increased number of intracellular mitochondria, thickening of basement membrane and vacuolization and collagenous deposition in interstitium. These above findings offer that orchiopexy should be performed in children who are about 1 year old. Also removal of the abdominal testis should be considered even when the patient is less than 2 years old because the possibility of fertility is unlikely and the patient is more prone to cancer.
