1.A Case of Eccrine Acrospiroma in Scrotum.
Korean Journal of Urology 1996;37(12):1424-1430
Acrospiroma is a rare benign tumor and a clinicopathologically distinctive neoplasm differentiating toward the distal part of the eccrine sweat gland. I experienced a case of dermal acrospiroma in a 59-year-old man who had a 7.0x6.5 x 5.3 cm sized, slowly growing, brown colored, smooth-surfaced mass on the right scrotum for 3 years. Histological examination revealed lobular structures composed of small fusiform cells and large eosinophilic polyhedral cells. Histochemically some of large polyhedral cells had PAS-positive DPAS-negative glycogen and Alcian-positive mucin in cytoplasm. Immunohistochemical stainings for vimentin, S-100, low molecule keratin, and EMA were positive in the tumor cells. During 6 months follow up period after excision, there was no recurrence. However, it is necessary to follow up for a long period because some acrospiroma may recur after a long silence period.

3.Cohen Ureteral Reimplantation: Outcome of 58 Ureters in 34 Children.
Korean Journal of Urology 1994;35(3):248-253
Surgical results of 34 children (68 ureters) who underwent Cohen ureteral reimplantation in the last 6 years were evaluated. All children were followed at least 4 months after the operation. Indication for the repair consisted of vesicoureteral reflux in 22 children, obstructive megaureter in 8 children and ureterocele in 4 children. The underlying problems in 55 ureters ( 94.8% ) were successfully corrected. Surgical failures were persistent reflux in 2 ureters, new ipsilateral reflux in 1 ureter and contralateral reflux in 1 ureter. However, no ureteral obstruction was noticed in this series. In conclusion, the Cohen cross trigonal technique was a safe and effective method of ureteral reimplantation in children.

4.Enuresis and Urine Concentration in Healthy Preschool Children.
Korean Journal of Urology 1999;40(1):96-100
PURPOSE: To determine if the urine specific gravity(SG) plays a role in enuresis, the first morning urine SG of the healthy preschool nocturnal enuretic was compared with that of the nonenuretic. The results of desmopressin were analyzed according to the pretreatment urine SG to know if the urine SG can predict the responsiveness of the medication. MATERIALS AND METHODS: Five hundred twenty healthy preschool children aged 3-6 years were entered in this prospective observer-blinded study. A comparison was made between SG of the first morning urine specimen and results of questionnaire concerning the bed wetting and voiding habits of children. The responsiveness to oral desmopressin(0.2-0.4mg h.s.) in 14-day treatment periods was also analyzed according to the urine SG in 28 children with enuresis. The responder group was defined as a reduction of at least 50% from the number of wet night. RESULTS: The incidence of enuresis was 8.6 percent. Stastistically significant difference was found between the bedwetter and nonbedwetter group with regard to the urine SG(p<0.05). The overall response rate of desmopressin was 68 percent. There was no significant difference between the responder and nonresponder group with respect to urine SG. CONCLUSIONS: The first morning urine of the enuretic showed higher probability of lower level of the SG than that of the nonenuretic. Treatment with desmopressin was associated with a significant decrease in the number of wet night, but clinical response was not predictable based on the first morning urine SG.

5.Penile Paraffinoma: 42 Cases.
Korean Journal of Andrology 1998;16(2):191-195
PURPOSE: Penile paraffinoma provokes many serious undesirable effects. We studied our series retrospectively to evaluate the outcome of surgical treatment according to the degree of penile skin defect after excision of the lesion. PATIENTS AND METHODS: Surgical treatment for penile paraffinoma was performed in 42 patients over 6 years. The operative methods were complete excision with primary closure (N=34) or bilateral pedicle scrotal flap (N=8). RESULT: The complications of bilateral pedicle scrotal flap were wound infection in 1 case and skin defect in 1 case. There were no complications of primary closure. CONCLUSIONS: We propose that the proper treatment of penile paraffinoma is complete excision with primary closure for a small denuded penis and bilateral pedicle scrotal flap for a large denuded penis.

8.Significant Issues Derived from the Choice of a PSA Test for Measuring PSA in Serum: Comparison of IMx Enzyme immunoassay and ELSA Immunoradiometric Assay.

Prostate specific antigen (PSA) has become established as the most useful serological marker for monitoring patients with prostate cancer. However, the benefits of serum PSA values are controversial in screening procedures for prostate cancer due to the rather low specificity of PSA test. To determine if different assays yield comparable results, we compared the IMx PSA enzyme immunoassay and the ELSA PSA monoclonal immunoradiometric assay. We analyzed 72 serum specimens from 68 patients with prostatic disease (12 patients with cancer, 47 benign hyperplasia and 9 prostatitis) and 13 from normal controls by both assays. Results from the assays revealed close linear correlation but the ELSA PSA assay yielded values 1.5 times those of the IMx PSA assay In 13 patients with histologically diagnosed benign prostatic hyperplasia, number of patient with PSA value over l0 ng/ml measured by IMx and ELSA assay were 2(15% ) and 4(31%), respectively. We conclude that the proportional bias between assays demonstrates a need for improved standardization of PSA assays.

PURPOSE: There diagnostic modalities have been commonly used to detect prostate cancer to date: digital rectal examination (DRE), serum prostate specific antigen (PSA) and transrectal ultrasonography(TRUS). We evaluated the diagnostic values of these three modalities in the early detection of prostate cancer. MATERIALS AND METHODS: We analysed 215 patients with low urinary tract symptoms who had pathologic diagnosis for prostatic cancer was possible by biopsy or transurethral resection. Transectal ultrasonography guided sextant biopsies were performed if the PSA level was greater than 4.0 ng/ml or DRE was suspicious, even if TRUS revealed no ateas suspicious for cancer. TURP were performed without TRUS or biopsies if the PSA level was lesser than 4.0 ng/ml and DRE was negative. RESULTS: Of the 215 patients, 36 (16.7%) revealed prostate cancer. Positive predictive value, sensitivity and specificity was 37.0%. 83.3%. 71.5% for DRE, 30.0%, 91.7%, 58.3% for PSA and 27.6% 58.3%. 43.3% for TRUS respectively. Positive findings on serum PSA or DRE or both tests detected significantly more tumors(97.2%, 35of 36 cancers) than only PSA (91.7%, 33 for 36 cancers), DRE (83.3%, 30 of 36 cancers) and TRUS (60.0%, 21 of 35 cancers) alone. CONCLUSIONS: These result shows that DRE is more valuable and cost effective method for detection of prostate cancer than serum PSA and the use of DRE in conjunction with serum PSA enhances prostate cancer detection.

We treated 11 patients with advanced transitional cell carcinoma of upper urinary tract with adjuvant M-VAC chemotherapy and their median survival time was compared with 9 patients without M-VAC chemotherapy as e historical group. The total number of cycles per each patient ranged from 1 to 5 with a mean of 3.4. Of these patients, 8 patients could be evaluated for response and 4 patients were responded (2 complete and 2 incomplete. response rate 50%). The median duration of response was 26 months for complete responders and 4.5 months for incomplete responders. The median duration of survival for all chemotherapy group, complete responders, progression and historical control group were 22, 23+, 14 and 21 months. respectively. Median survival was 22 months in all 11 patients. 23+ months in clinical responders, 14 months in progression and 21 months in historical control group. Although overall survival was not prolonged significantly in chemotherapy than the historical control group, M-VAC was effective in small proportion of patients (CR: 2/8). The duration of survival of the patients with complete remission was prolonged significantly.
