Overactive bladder(OAB) is a symptom syndrome including urinary urgency with or without urinary incontinence, usually combined with frequency and nocturia. There are lots of reports concerning the first-line treatment for OAB, the treatment is still challenging. Extracorporeal magnetic innervation(ExMI) therapy have been known to be safe and effective immediately in stress urinary incontinence and OAB. The aim of this study was to assess the effect of suprapubic magnetic innervation therapy by arm-typed plate in patients with OAB.

The selected subjects were 32 patients diagnosed with OAB between the periods of April to September, 2007. Mean age was 48.3±10.7 years old, and there were 10 males and 22 females patients. Voiding diary, International Prostatic Symptoms Score(IPSS), quality of life(QOL) questionnaire were evaluated as assessment of voiding symptoms. The treatment was performed for 15 minutes, 2 times a week, for 6 weeks with ExMI by arm-typed plate(BioCon-2000. M-Cube, Korea). All of the evaluations were repeated immediately and 3 months after treatment.

The mean urgency episodes decreased from 13.2±1.81 times to 8.7±1.95 times immediately after treatment and 9.6±2.18 times at 12 weeks after treatment(p<0.05). At 6 weeks after starting treatment, the mean frequency decreased from 5.4±1.58 times to 3.6±1.37 times(p<0.05), but the mean frequency after 6 months was 4.3±1.72 times(p>0.05). Significant improvements immediately after treatment were noted in the frequency, urgency, and QOL in IPSS, which were maintained for 3 months(p<0.05). There were improvements in mean voided volume, but these were minimal.

The symptoms of OAB are highly prevalent and significantly affect the quality of life. Effective and prompt management of OAB should be implemented. Our datas suggested that the EXMI therapy by arm-typed plate has the favorable effect on OAB and it may be persist for at least 12 months. Further studies are needed to establish the long-term efficacy of EXMI therapy in patients with symptoms of OAB.

Chronic kidney disease(CKD) and Sexual dysfunction are important public health problems in older man as a part of life. We investigated the relationship between two groups.

We examined sixty-five CKD patients on glomerular filtration rate (GFR), serum creatinine (sCr), Prevalence period and causative disease. Sexual function was evaluated by International Index of Erectile Function(IIEF-5), libido(2 items), ejaculation(4 items), frequency of sex in a month and serum testosterone. A control group composed of eighteen male adults who had visited to the general medical testing center in the hospital. They didn't have any combined disease and they were similar age range to the group of the CKD. We analyzed correlations between components of the CKD and sexual function.

The study revealed that all sexual components of the CKD group(mean age 51.8±2.6) were significantly worse than the control group; 12.3±3.9 of IIEF-5, 5.4±1.8 of libido and 10.1±2.2 of ejaculation, 1.4±0.7times of sex in a month in the CKD group and 18.3±3.5 of IIEF-5, 7.2±2.1 of libido and 15.3±2.9 of ejaculation, 2.9±1.1 times of sex in a month in the control group. The patients whose prevalence period of CKD was over than 3 years or whose sCr was over than 2.0ng/ml, had all sexual components worse significantly. Comparing by the causative disease of the CKD, there was no any significant difference. Analyzing by correlation, erectile function is related with serum glucose, sCr, Prevalence periods and libido is related with prevalence periods, and ejaculation is related with diabetes.

The patients with CKD may have a sexual dysfunction that make erection, libido and ejaculation and the number of their sex seemed to decrease. Therefore we need to have more attention to their sexual function as an important part of life.
