A Prostate Neoplasm Distantly Metastasized to the Unilateral Ureter / 대한비뇨기과학회지

Neoplasms of the prostate usually metastasize to pelvic lymph nodes or bone, or directly invade the adjacent pelvic organs. Ureteral metastasis of a prostatic carcinoma, without ascending spread along the ureter, is very rare, with only a few having been reported from autopsy series. Herein, the case of a prostatic carcinoma, distantly metastasized to the unilateral ureter, is reported.

The Effect of Lower Urinary Tract Symptoms on Erectile Function and the Frequency of Sexual Intercourse / 대한비뇨기과학회지

PURPOSE: Lower urinary tract symptoms (LUTS) usually co-exist with erectile dysfunction. Although the mechanisms for this are still unknown, there seems to be a correlation between the two diseases. We evaluated the effect of lower urinary tract symptoms on the erectile function and the frequency of sexual intercourse. MATERIALS AND METHODS: 1,216 patients, who visited our hospital due to LUTS from January 2000 to April 2006, were evaluated for their erectile function with using International Index of Erectile Function-Erectile Function (IIEF-EF) domain score, frequency of sexual intercourse per month during the last 3 months, prostate volume, International Prostate Symptom Score (IPSS) and quality of life (QoL). The patients were divided into five groups according to age: younger than 40, 40-49, 50-59, 60-69 and older than 70. The patients were again divided into three group according to IPSS: mild (0-7), moderate (8-19) and severe (20-35). Multiple regression analysis and two-way ANOVA were used to analyze the data. RESULTS: 772 patients were eligible for the analysis. The mean patient age was 53.6+/-12.6 years, the mean IPSS was 13.8 9.2 and the mean IIEF-EF score was 17.0+/-9.4. Among the age and LUTS parameters, only age and IPSS had significant effect on the erectile function (p<0.01). The IIEF-EF domain score showed significant differences among the each age group and also among the age-adjusted IPSS groups (p<0.01, p=0.023). The frequency of sexual intercourse per month during the last 3 months showed a significant difference among the each age group (p<0.01). CONCLUSIONS: Erectile function declines with the age-adjusted LUTS severity as well as with age. The frequency of sexual intercourse per month during the last 3 months declines with age, but not with the age-adjusted LUTS severity.

Prevalence of Premature Ejaculation in Chronic Pelvic Pain Syndrome / 대한남성과학회지

PURPOSE: Premature ejaculation is a common male sexual dysfunction and has an adverse effect on QoL(quality of life). Chronic pelvic pain syndrome(CPPS) is also a common and serious health problem affecting QoL. Although both disorders are common their etiopathogeneses are not well understood. We investigated the prevalence and effect of premature ejaculation on erectile function in CPPS patients and compared these patients with healthy control subjects. MATERIALS AND METHODS: 638 CPPS patients and 102 healthy controls were enrolled in this study. Each patient was given a questionnaire consisting of 3 parts: a demographic data questionnaire, the Korean version of the NIH-CPSI(National Institutes of Health-Chronic Prostatitis Symptom Index), and IIEF(International Index of Erectile Function). Premature ejaculation was defined as intravaginal ejaculation latency of less than 3 minutes with the same partner for at least 6 months. RESULTS: 303 patients with CPPS and 83 healthy controls were eligible for the analysis. The rate of premature ejaculation was much higher in patients with CPPS(71.62%) than healthy controls(22.89%), and this difference was statistically significant(p < 0.01). In the patients with CPPS, the frequency of sexual intercourse per month during the last 3 months was 4.79+/-3.43. In the patients with CPPS, the mean scores for IIEF-EF(erectile function), IIEF-IS(intercourse satisfaction), IIEF-OF(orgasmic function), IIEF-SD(sexual desire) and IIEF-OS(overall satisfaction) were 21.7+/-6.4, 8.5+/-2.9, 7.4+/-2.5, 5.3+/-2.0 and 5.2+/-2.1, respectively. Each mean IIEF domain score was lower than healthy controls, and these differences were statistically significant. But in the patients with CPPS categorized in IIIa and IIIb, the frequency of sexual intercourse and each IIEF domain score showed no difference. CONCLUSIONS: The rate of premature ejaculation was higher in the patients with CPPS than healthy controls.
