ABSTRACT
AIM: Erectile dysfunction (ED) is common in patients with diabetes mellitus (DM) as well as those undergoing hemodialysis (HD). The purpose of this study is to investigate the frequency and severity of ED in HD patients with DM and those without DM. In addition, we examined the relationship between erectile function and several risk factors, including presence of DM and hemoglobin A1c levels in HD patients. METHODS: This study involved 180 patients on HD, including 66 HD patients with DM (DM-HD) and 114 patients without DM (non-DM-HD). We evaluated erectile function using an abridged five-item version of the international index of erectile function (IIEF-5). Logistic regression analysis was used to investigate the relationship between presence of ED and several risk factors. RESULTS: The total score of IIEF-5 in DM-HD patients (9.5 +/- 4.2) was significantly lower than in non-DM-HD patients (13.5 +/- 5.7). The prevalence of severe ED was 42.4% and 18.4% in DM-HD patients and non-DM-HD patients, respectively. Age, cardiovascular disease history, and DM were identified as independent risk factors for the presence of ED. Furthermore, age and elevated hemoglobin A1c levels were identified as independent risk factors for the presence of severe ED. CONCLUSION: DM-HD patients are more likely to have ED, and particularly severe forms of ED, than non-DM-HD patients. DM and elevated hemoglobin A1c levels were associated with the presence of ED or severe ED, respectively. Aging was identified as an independent factor in both ED and severe ED.

We describe a technique that uses simultaneous two-plane images to facilitate endoscopic recanalization of prostatomembranous urethral disruption. This technique is very useful for identifying the true passage and to perform endoscopic recanalization safely.

PURPOSE: Intravesical instillation of epirubicin (EPI) is one of the most effective adjuvant therapies for non-muscle-invasive bladder cancer after transurethral resection. We evaluated the optimal duration of EPI instillation in a multi-institution prospective randomized clinical study. METHODS: Between June 1995 and May 1998, a total of 125 patients with superficial bladder cancer (transitional cell carcinoma grade 1 or 2) were enrolled in this study, and 102 patients were fully evaluated for recurrence. Two protocols for intravesical therapy (arm A - 30 mg EPI/30 ml saline 19 times over 1 year; arm B - 30 mg EPI/30 ml 12 times over 5 months) were established. Instillations were given every week for 4 weeks and then every 2 weeks for 4 months in arm B. After 5 months of treatment, maintenance was performed with seven further instillations (one every month for 7 months) in arm A. The analyzed background factors were the therapeutic method, gender, history (primary or recurrent tumor), stage (T classification), grade, number of tumors, and tumor size. RESULTS: There were no significant differences in the analyzed background factors between the two arms, and there were no serious side effects in the study. In an intent-to-treat analysis, the overall 3-year recurrence-free survival rates were 48.5% in arm A and 55.1% in arm B. The difference between the two groups was not significant. CONCLUSIONS: This analysis indicated that extended prophylactic maintenance instillation of EPI was not significantly effective in reducing bladder cancer recurrence.
