Association between Lower Urinary Tract Symptoms and Erectile Dysfunction in Aging Men: Hallym Aging Study / 대한비뇨기과학회지

PURPOSE: The aim of this study was to investigate the relationship between lower urinary tract symptoms(LUTS) and erectile dysfunction(ED) in a population-based cohort study, Hallym Aging Study(HAS). MATERIALS AND METHODS: Among the 1,520 participants in HAS, 300 men aged > or=50 years, who underwent detailed health evaluations, includeing health-related questionnaires, evaluation of the medical history and various life style factors as well as clinical measurements, were included in the study. LUTS and ED were assessed by validated questionnaires, the International Prostate Symptom Score(IPSS) and a 5-item version of the International Index of Erectile Function(IIEF-5). RESULTS: The prevalence and severity of LUTS and ED increased and significantly with age(p<0.001). The IIEF-5 score declined as the severity of LUTS increased in each age group. There was a significant negative correlation between the IPSS score and the IIEF-5 score(age adjusted r= ?0.275, p<0.001). The multivariate logistic regression analysis, controlling for age and comorbidities, showed that men with moderate/ severe LUTS were 4-9 times more likely to have ED than men with no/mild LUTS; in addition, men with ED were 5 times more likely have moderate/severe LUTS than men without ED. CONCLUSIONS: The presence and severity of LUTS were independent risk factors for ED and vice versa. These results highlight the clinical importance of evaluating LUTS in patients with ED, and the need to consider the presence of ED in the management of patients with LUTS

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.

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.

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
