Association between Erectile Dysfunction and Metabolic Syndrome in Aging Men: Hallym Aging Study

PURPOSE: The aim of this study was to investigate the relationship between erectile dysfunction (ED) and metabolic syndrome (MS) in a population-based cohort study, the Hallym Aging Study (HAS). MATERIALS AND METHODS: Among the 1,520 participants in HAS, 278 men aged more than 50 years, who underwent detailed health evaluations, including health-related questionnaires, evaluation of their medical history and various lifestyle factors, as well as clinical measurements, were included in the study. ED and MS were assessed by using a 5-item version of the International Index of Erectile Function (IIEF-5) and the guidelines of the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III), respectively, and the relationship between ED and MS was investigated. RESULTS: Of the 278 men, 120 (43.2%) had MS. Ninety percent of men with MS and 78.5% of men without MS had ED (p<0.05), and chi-square analysis revealed significant differences in the rate of MS between groups when stratified by ED severity (p<0.001). The multivariate logistic regression analysis, with control for age and comorbidities, showed that men with MS were 3 times as likely to have ED as were men without MS. Among the metabolic risk factors, only waist circumference (WC) was significantly associated with the presence and severity of ED (p<0.05). CONCLUSIONS: The presence of MS was an independent risk factor for ED, and WC was the most significant metabolic risk factor predicting the risk of ED. These results highlight the clinical importance of evaluating ED in patients with MS, especially in patients with abnormal WC.

477 Bladder Calculi in a Patient with Benign Prostatic Hyperplasia

We report on a patient with 477 bladder calculi secondary to benign prostatic hyperplasia. To our knowledge this patient had one of the highest numbers of the bladder calculi reported.

The Effect of Tape-tension Change on Outcome of Tension-free Vaginal Tape Procedure and Voiding Function

PURPOSE: The aim of this study was to investigate the effect of tape-tension on outcome of tension-free vaginal tape(TVT) procedure and voiding function. MATERIALS AND METHODS: We included 62 women patients with stress urinary incontinence. The patients were randomized into two groups and underwent the TVT procedure according to the standard method with some modifications. In group I(n=28), the position of the tape was adjusted with no tension by placing Mayo scissors between the tape and urethra and in group II(n=34), the tape was placed in the same fashion except that create 5mm-long tape loop under urethra for more loosening the tape-tension than that of group I. The success rate of TVT, the rate of postoperative voiding dysfunction and pre- and postoperative quality of life(QOL), peak urinary flow rate(Qmax), post-void residual(PVR) were compared between the two groups. RESULTS: There were no significant differences in success rate and improvement of QOL between the groups. In group I, Qmax was significantly decreased and the PVR was significantly increased after TVT compared with group II. The voiding dysfunction after TVT occurred in 3(10.7%) and 1(2.9%) in group I, II respectively, and there was no significant difference. CONCLUSIONS: These data suggest that some loosening of the tape-tension in TVT procedure has no effect on the success of TVT and improvement of QOL. By some loosening of the tape-tension, postoperative voiding function could be improved and this finding would be helpful especially in patients with preoperative risk factor for voiding dysfunction after TVT.

Accessory Scrotum Associated with a Perineal Lipoma / 대한비뇨기과학회지

The presence of accessory scrotum is a condition characterized by additional scrotal tissue with a normally developed scrotum. The condition is extremely rare and can be associated with a perineal lipoma. Herein, a case of accessory scrotum associated with a perineal lipoma is reported in a 4-day-old boy. He presented with a perineal mass and the diagnosis was confirmed by surgical excision and subsequent histological analysis. This is the first Korean report of an accessory scrotum associated with perineal lipoma. (Korean J Urol 2007;48:1096-1098)

Neonatal Adrenal Hemorrhage Presenting as Acute Scrotum / 대한비뇨기과학회지

There has been only 23 cases of neonatal adrenal hemorrhage presenting as an acute scrotum and unnecessary surgical exploration was performed in nine of these case(39%) due to suspected testicular torsion. We report here on a case of a 2-day-old boy with neonatal adrenal hemorrhage, and he presented with an acute scrotum; this child's condition was managed conservatively.

Torsion of the Testicular Appendix in Undescended Testis / 대한비뇨기과학회지

Torsion of the testicular appendix is a common cause of acute scrotum, and occurs during the prepubertal years. However, despite its high incidence, appendix torsion in undescended testis has rarely been reported. Herein, a rare case of torsion of the testicular appendix in an undescended testis is reported in a 9-year-old boy
