Clinical Factors Associated With Dose Escalation of Solifenacin for the Treatment of Overactive Bladder in Real Life Practice / 대한배뇨장애요실금학회지

PURPOSE: To determine the baseline clinical characteristics associated with dose escalation of solifenacin in patients with overactive bladder (OAB). METHODS: We analyzed the data of patients with OAB (micturition frequency > or =8/day and urgency > or =1/day) who were treated with solifenacin and followed up for 24 weeks. According to our department protocol, all the patients kept voiding diaries, and OAB symptom scores (OABSS) were monitored at baseline and after 4, 12, and 24 weeks of solifenacin treatment. RESULTS: In total, 68 patients (mean age, 60.8+/-10.0 years) were recruited. The dose escalation rate by the end of the study was 41.2%, from 23.5% at 4 weeks and 17.6% at 12 weeks. At baseline, the dose escalator group had significantly more OAB wet patients (53.6% vs. 20.0%) and higher total OABSS (10.2+/-2.4 vs. 7.9+/-3.5, P=0.032) than the nonescalator group. OAB wet (odds ratio [OR], 4.615; 95% confidence interval [CI], 1.578-13.499; P<0.05) and total OABSS (OR, 1.398; 95% CI, 1.046-1.869; P<0.05) were found to be independently associated with dose escalation. CONCLUSIONS: Patients who have urgency urinary incontinence and high total OABSS have a tendency for dose escalation of solifenacin.

Effect of Combined Systematized Behavioral Modification Education Program With Desmopressin in Patients With Nocturia: A Prospective, Multicenter, Randomized, and Parallel Study / 대한배뇨장애요실금학회지

PURPOSE: The aims of this study were to investigate the efficacy of combining the systematized behavioral modification program (SBMP) with desmopressin therapy and to compare this with desmopressin monotherapy in the treatment of nocturnal polyuria (NPU). METHODS: Patients were randomized at 8 centers to receive desmopressin monotherapy (group A) or combination therapy, comprising desmopressin and the SBMP (group B). Nocturia was defined as an average of 2 or more nightly voids. The primary endpoint was a change in the mean number of nocturnal voids from baseline during the 3-month treatment period. The secondary endpoints were changes in the bladder diary parameters and questionnaires scores, and improvements in self-perception for nocturia. RESULTS: A total of 200 patients were screened and 76 were excluded from the study, because they failed the screening process. A total of 124 patients were randomized to receive treatment, with group A comprising 68 patients and group B comprising 56 patients. The patients' characteristics were similar between the groups. Nocturnal voids showed a greater decline in group B (-1.5) compared with group A (-1.2), a difference that was not statistically significant. Significant differences were observed between groups A and B with respect to the NPU index (0.37 vs. 0.29, P=0.028), the change in the maximal bladder capacity (-41.3 mL vs. 13.3 mL, P<0.001), and the rate of patients lost to follow up (10.3% [7/68] vs. 0% [0/56], P=0.016). Self-perception for nocturia significantly improved in both groups. CONCLUSIONS: Combination treatment did not have any additional benefits in relation to reducing nocturnal voids in patients with NPU; however, combination therapy is helpful because it increases the maximal bladder capacity and decreases the NPI. Furthermore, combination therapy increased the persistence of desmopressin in patients with NPU.

Elimination of Hunner's Ulcers by Fulguration in Patients With Interstitial Cystitis: Is It Effective and Long Lasting?

PURPOSE: To evaluate the outcome of fulguration of Hunner's ulcers (HUs) in painful bladder syndrome/interstitial cystitis (PBS/IC) that is refractory to conservative treatment. MATERIALS AND METHODS: Patients diagnosed with refractory PBS/IC and treated with fulguration between 2011 and 2013 were identified through screening of medical records. To evaluate treatment outcomes, voiding diaries, the visual analogue scale (VAS) for pain, and two IC symptom questionnaires (pelvic pain and urgency/frequency scale [PUF] and O'Leary-Sant IC symptom index and IC problem index [OS]) were used. Fulguration was deemed to be successful if the VAS score was <2 or less than half of the preoperative VAS score. RESULTS: In total, 27 patients with PBS/IC in whom conservative treatments had failed were enrolled. Two months after fulguration, decreases were observed in the mean 24-hour urinary frequency (from 16.0 to 10.2), 24-hour urgency episodes (8.0 to 1.8), and the VAS (5.8 to 1.2), PUF symptom (15.1 to 7.0), PUF bother (8.4 to 2.7), OS symptom (15.1 to 7.2), and OS problem (13.8 to 6.0) scores. At 5 and 10 months, all variables had worsened. At 2, 5, and 10 months, the success rates were 94.1%, 70.0%, and 33.3%, respectively. Four patients underwent one repeat fulguration on average 11.3 months after the first fulguration. Repeat fulguration was not significantly associated with any clinical characteristics. CONCLUSIONS: In PBS/IC that was refractory to medication or other conservative treatments, HU elimination by fulguration effectively improved symptoms. However, this effect decreased gradually over time.

A Case of Xanthogranulomatous Prostatitis Concurrent with a Prostatic Abscess / 대한남성과학회지

Xanthogranulomatous prostatitis is a rare inflammatory condition of the prostate. We report a case of xanthogranulomatous prostatitis. An 82-year-old man presented to our emergency department complaining of gross hematuria. A hard, enlarged, non-tender prostate was palpated on digital rectal examination. Urinalysis showed hematuria and pyuria, and the complete blood count (CBC) revealed leukocytosis. The prostate-specific antigen (PSA) level was elevated at 86.8 ng/ml. Computed tomography (CT) showed an enlarged prostate (volume 100 ml) that protruded into the bladder base. In the left lobe of the prostate, a 1.2x1.1-cm abscess was seen. Transurethral resection of the prostate was done. The pathological diagnosis was xanthogranulomatous prostatitis. The natural progression of the disease is unknown because of the paucity of cases and long-term follow-up reports. To evaluate the pathogenesis and long-term features of progression of this disease, more clinical cases should be collected.

A Study Assessing the Quality of Life Related to Voiding Symptoms and Sexual Functions in Menopausal Women

PURPOSE: To investigate the impact of menopause on the quality of life (QoL) of middle-aged and older women, including their general well-being, voiding-related symptoms, and sexual distress. MATERIALS AND METHODS: To assess QoL, we administered a questionnaire that included questions about voiding-related symptoms and female sexual distress and part of the Women's Health Questionnaire. The self-administered questionnaires were completed by 1,679 women in the Korea. Data for 1,262 women were available for analysis, including premenopausal (n=307), perimenopausal (n=240), and postmenopausal (n=715) groups. RESULTS: Voiding-related discomfort increased significantly in perimenopausal and postmenopausal women compared with premenopausal women (p<0.001). General well-being worsened as menopause progressed (p<0.001). Menopausal women who were older (p=0.014), had a hysterectomy (p=0.005), or had urinary incontinence (p=0.001) had more voiding-related symptoms. Hypertension (p=0.026), cardiac disease (p=0.013), and arthritis (p=0.001) resulted in significantly decreased general well-being. Women with a hysterectomy (p=0.017) and those with arthritis (p=0.004) had high sexual distress. In the menopausal group, employed women had better general well-being than did unemployed women. CONCLUSIONS: Menopause negatively affected the QoL of middle-aged and older women because of decreased general well-being and increased voiding-related symptoms. General health, even in menopausal women, was important to maintain a better QoL. To preserve the QoL of women undergoing menopause, control of menopause and underlying disease should be considered.

A Survey of Understanding of Viagra in primary Physician and General Population / 대한남성과학회지

PURPOSE: Sildenafil citrate(Viagra(R)), a PDE-5 inhibitor in the corpus carvenosum to facilitate penile erection has improved impaired erectile responses in men and has been accepted as a primary treatment of erectile dysfunction. However, complications occurred by Viagra have increased due to its overuse and misuse. Therefore, we have performed a survey to compare physicians and general population in Busan, Korea to assess their understanding of Viagra. Methods and Materials: In 2007, printed surveys were mailed to randomly sampled candidates of 197 primary physicians and 696 individuals from general population, 327 medical students in Busan were surveyed by door-to-door visits. We assessed opinions associated with Viagra eliciting their understanding about its safety, direction, and complications. Data were analyzed using SPSS and were identified by crosstabulation analysis using Ki-square test. RESULTS: Of 1,265 eligible responses, several differences were found between the 3 groups. Compared to general population, the others were more likely to understand the efficacy, directions, and complications of Viagra. Physicians and medical students(43.1% and 39.0%) gave more preference than general population(26.1%) to using Viagra. There were differences in understanding of Viagra with changes of education level. However, it showed no significant differences about idea of illegal Viagra and combination usage with nitrates. Conclusion: The number of patients using Viagra is increasing but their understanding about Viagra is still poor. Moreover, general populations understand Viagra as 'assistant' for erection poorly. Even some medical students understand more than physicians. The ideas of complications would likely affect to negative thinking about usage for Viagra. Therefore more active and continuous educations for proper use of Viagra are suggested for medical efficacy and less complications.
