A statistical analysis was made on patient of recurrent urinary stones during the period from May 1972 to April 1977 in the Department of Urology of Han Yang University Hospital and the results were obtained as following: 1. Among the 894 patient of in-patient, 290 patient were urinary stone patients (32.8 %). 2. The recurrent patients were 11 (20%), with the follow-up period from 1 year to 10 years, in whom follow-up was possible. 3. The most common age group of recurrent stones were from 20 to 40 years old ( 72.8%). 4. The mean period from primary stone to recurrent stone was 4.4 years. 5. Among the recurrent patient, 2 were prolonged recumbency patients and one had duplicated ureter. Others were idiopathic recurrent stones. 6. If the primary stone was removed by operation, recurrent stone was some hard to be passed spontaneously.

In a number of urinary calculi, 89. 8 percent was single and 5.8 percent was double and 4.4 % was more than 2. 7. The ureterolithotomy was performed on 74 of 197cases requiring surgical intervention. Cystoscopic manipulation (Spontaneous Expelled) and conservative treatment were 120 cases of 197 cases. Other manner on 3 cases. 8.

Phosphate + oxalate in 53.7 percent, Cal phosphate in 13.7 percent, Calcium phosphate + ammonate in 7.5 percent, Ca phosphate +carbonate in 7.1 percent, Ca carbonate in 5.O percent. Ca oxalate in' 4.2 percent. etc.

The adequacy of the urologist work force in Korea has never been investigated. This study investigated the geographic distribution of urologists in Korea. County level data from the National Health Insurance Service and National Statistical Office was analyzed in this ecological study. Urologist density was defined by the number of urologists per 100,000 individuals. National patterns of urologist density were mapped graphically at the county level using GIS software. To control the time sequence, regression analysis with fitted line plot was conducted. The difference of distribution of urologist density was analyzed by ANCOVA. Urologists density showed an uneven distribution according to county characteristics (metropolitan cities vs. nonmetropolitan cities vs. rural areas; mean square=102.329, P<0.001) and also according to year (mean square=9.747, P=0.048). Regression analysis between metropolitan and non-metropolitan cities showed significant difference in the change of urologists per year (P=0.019). Metropolitan cities vs. rural areas and non-metropolitan cities vs. rural areas showed no differences. Among the factors, the presence of training hospitals was the affecting factor for the uneven distribution of urologist density (P<0.001).Uneven distribution of urologists in Korea likely originated from the relatively low urologist density in rural areas. However, considering the time sequencing data from 2007 to 2012, there was a difference between the increase of urologist density in metropolitan and non-metropolitan cities.

A statistical analysis was made on 124 cases of urinary calculi during the period from Jan. 1968 to Aug. 1971 on the Department of Urology of Capital Military Hospital, and the results were obtained as following; 1. The incidence of urinary: calculi was 2.04% of out-patients. 2. The age of the patients ranged from 20 to 30 years in approximately 75.8%. 3. A seasonal occurrence was a most high during summer on 41.6%. 4. The locational distribution of urinary calculi was 59.7% in ureter, 28. 2% in kidney, 8. 1% in bladder, 4.0% in urethra. Approximately 9. 1% of the upper urinary calculi was found bilaterally. 5. The most favored predirection of ureteral stone was lower one-third in 70.2% of all cases. 6. In a number of urinary calculi, 83.9% was single and 16.1% was more than 2. 7. The ureterolithotomy was performed on 40 of 80 cases requiring surgical intervention. Cystoscopic manipulation and conservative treatment were 13. 1% in the each. 8. The results of qualitative analysis of 73 urinary calculi showed calcium phosphate + oxalate in 49.3%, calcium phosphate in 16.4%, calcium oxalate in 15.1%, calcium carbonate in 8.2%, calcium phosphate + uric acid in 4.1%, calcium oxalate + urate in 4.1%, calcium phosphate +ammonium in 2.8%.

PURPOSE: In Korea, there was no specific guidelines for the management of benign prostatic hyperplasia (BPH). We reviewed the practice patterns of Korean urologists in the management of BPH and aimed to describe the need to develop specific guidelines. MATERIALS AND METHODS: A probability sample was taken from the Korean Urological Association Registry of Physicians, and a structured questionnaire, that explored practice patterns in the management of BPH, was mailed to a random sample of 251 Korean urologists. RESULTS: For the initial evaluation of BPH, most urologists routinely performed prostatic specific antigen (PSA) (96.4%), digital rectal exam (94.4%), international prostate symptom score (IPSS) (83.2%) and transrectal ultrasound (79.2%). Symptom assessment (36.4%) followed by transrectal ultrasound of prostate (TRUS) (20.0%) was considered as the most important diagnostic examination affecting the decision about individual treatment options. Almost all urologists (92.2%) chose medical treatment as the first-line treatment option for uncomplicated BPH with moderate symptoms. Of the respondents, 57.2% had prescribed alpha blocker and 41.6% alpha blocker plus 5-alpha reductase inhibitors as the medical treatment option for BPH. The prescription of 5-ARIs was dependent on the size of the prostate and the severity of symptoms. CONCLUSION: The results of our current survey provide useful insight into variations in the clinical practice of Korean urologists. They also indicate the need to develop further practical guidelines based on solid clinical data and to ensure that these guidelines are widely promoted and accepted by the urological community.

BACKGROUND: There were many statistical studies about skin tumors. However, no articles have been reported which focus on the scalp tumors up to the present. OBJECTIVE: The purpose of our study was to analyze the epidemiologic aspect of scalp tumors, and compare them with other data related to skin tumors. METHODS: A statistical analysis was made using 251 cases of scalp tumors which were confirmed by histopathological study from January 1993 to December 2002 at Seoul National University Hospital. RESULT: 1. In the 251 cases of scalp tumors, 197 cases (78.5%) were benign scalp tumors, and 54 cases (21.5%) were malignant scalp tumors. 2. Among the 197 cases of benign scalp tumors, the most common tumor was nevus sebaceus (19.3%), followed by seborrheic keratosis (13.7%), epidermal cyst (10.2%), trichilemmal cyst (9.1%), lipoma (7.7%), intradermal nevus (7.1%), neurofibroma (6.1%). 3. Among the 54 cases of malignant scalp tumors, the most common tumor was metastatic cancer (31.5%), followed by basal cell carcinoma (18.5%), angiosarcoma (9.3%), squamous cell carcinoma (9.3%), lymphoma (7.4%), and so on. 4. Male to female ratio of benign scalp tumor was 1.3:1 and that of malignant scalp tumor was 1.1:1 5. The distribution of age of benign scalp tumor was relatively even from childhood to old age, but that of malignant scalp tumor showed that about 70% of cases were over 4th decade. 6. The distribution of each department which performed scalp biopsy was the following ; department of dermatology (49.2%), plastic surgery (21.8%), neurosurgery (17.3%), general surgery (11.2%), pediatrics (0.5%) at benign scalp tumor and department of dermatology (37%), neurosurgery (20.4%), plastic surgery (16.7%), general surgery (7.4%), internal medicine (7.4%), urology (5.6%), otolaryngology (3.7%) and emergency medicine (1.9%) at malignant scalp tumor.
