OBJECTIVES: Chromosomal anomalies are common disease entity among genetic diseases. But there are scanty reports about the status of chromosomal abnormalities in Korean. In addition, the comprehensive multi-center study of chromosomal abnormalities in Korean has never been performed. METHODS: We have collected 1,793 cases (394 abortuses; 198 chorionic villi; 1,060 amniotic fluid cells; 141 fetal blood), which showed abnormal karyotype results from twenty three cytogenetic centers in Korea from the year of 1977 to 1999. RESULTS: In abortuses, numerical chromosomal abnormalities was 85%, and structural abnormalities was 13% and the most frequent anomaly was trisomy 16. In chorionic villi, numerical anomaly was 60.0% and structural anomaly was 31.3% and the most frequent karyotype was Down syndrome. In amniotic fluid cells, structural anomaly exceeded the number of numerical anomaly and the most frequent anomaly was Down syndrome. In fetal blood, numerical anomaly was 63.8% and the most frequent karyotype was trisomy 18 (23.4%) CONCLUSIONS: This may be the first comprehensive and multi-center study in Korea. The proportion of the abnormal karyotypes in each specimens was different from each other. Based on this study, the more comprehensive study should be performed to all the Korean population.

Inverted papilloma of the urinary tract is a rare benign lesion. We report, to our knowledge, the first case of inverted papilloma of the prostatic urethra arising in a juvenile. Our patient was referred for evaluation of painless, gross hematuria and voiding difficulty. Transrectal sonography demonstrated a 1.4 cm papillary lesion on the medial aspect of the prostatic urethra. Cystoscopy showed a solitary, papillary tumor on the prostatic urethra. Transurethral resection was performed and histological examination showed an inverted papilloma.

PURPOSE: The purpose of this study is to evaluate the preoperative factors that influenced postoperative sperm concentration after vasovasostomy. MATERIALS AND METHODS: We retrospectively reviewed 97 consecutive single-layer vasovasostomy procedures performed by a single surgeon between March 2003 and September 2010. The patients were stratified into three groups based on sperm concentration at 1 month follow-up: group I-azoospermia, group II-oligospermia, and group III-normal. We evaluated the preoperative factors that may have influenced sperm concentration at postoperative 1 month. Patients with serial semen analysis were divided into four groups according to the change in postoperative sperm concentration at the 6-month visit: group II-N-from oligospermia to normal, group II-O-from oligospermia to oligospermia, group III-O-from normal to oligospermia, group III-N-from normal to normal. We compared the pregnancy rate among the four groups. RESULTS: The mean obstructive interval was 9.69 years in group I, 6.02 years in group II, and 7.82 years in group III. There were significant differences found among the groups (p=0.035). There was significantly different change in sperm concentration, sperm motility, and sperm morphology between each of the groups. A total of 32 patients underwent serial semen analyses at 1 month, 3 months, and 6 months after vasovasostomy. There was no significant difference in patient age, obstructive interval, or follicle-stimulating hormone among the groups. The natural pregnancy rate in group II-O was lower than that in group II-N, and in group III-O was lower than that in group III-N. However, there was no significant difference among each of the groups. CONCLUSIONS: The sperm concentration after vasovasostomy was significantly related to the obstructive interval between vasectomy and reversal.

PURPOSE: The purpose of this study was to evaluate the annual changes in prostate variables and style of surgical treatment of patients with benign prostatic hyperplasia (BPH) over the past 12 years. MATERIALS AND METHODS: The subjects were 918 patients (January 1999-November 2010) who were treated by either open prostatectomy or transurethral resection of prostate (TURP). Every year, the performance ratio between open prostatectomy and TURP was evaluated. Before surgery, total and transitional zone volumes of the prostate were measured by transrectal ultrasonography (TRUS). After surgery, resection weight and residual volume of the prostate were measured by TRUS. RESULTS: From 2001 through 2010, the performance ratio of TURP increased greatly from 89% to 97%. During 1999 to 2010, the total volume of the prostate increased from 40.0 cc to 55.0 cc in the TURP group and from 74.1 cc to 116.7 cc in the open prostatectomy group. During 1999 to 2010, the mean resection volume of the TURP group increased from 2.3 cc to 20.1 cc. Also, the mean resection volume of the open prostatectomy group increased from 59.3 cc to 114.3 cc. During 1999 to 2003, the resection time of the TURP group decreased from 72.9 minutes to 43.2 minutes. CONCLUSIONS: During 1999 through 2010, the performance ratio between open prostatectomy vs TURP was high for TURP. The total volume and resection volume of the prostate increased annually, and the resection time decreased annually.
