2.Advances in researches on the relationship between prostatic diseases and erectile dysfunction.
National Journal of Andrology 2005;11(6):462-465
Prostatic diseases and erectile dysfunction (ED) are common diseases in urology and andrology. Basic and clinical studies have proved that there is a close relationship between the two. This article reviews the mechanism, diagnosis and treatment of ED caused by several prostatic diseases, such as acute prostatitis, chronic prostatitis, benign prostate hyperplasia and prostate cancer.

To evaluate the safety and efficacy of transrectal high-intensity focused ultrasound (HIFU) in the treatment of benign prostatic hyperplasia (BPH), serial studies were conducted in 150 BPH patients before and 30 min, 1, 2, 6 and 12 month(s) after Sonablate-500 HIFU treatment. A silicon-coated indwelling 16F latex catheter was placed during the determination of the therapy zone. Preoperative and postoperative evaluations were made by using the international prostate symptom score (IPSS), quality of life (QOL), uroflowmetric findings and transrectal ultrasound, and incidence of complications. The cystourethrography was done in 23 patients within 1 year postoperatively. The results showed that after HIFU treatment, IPSS and QOL scores were significantly decreased at 1, 2, 6 and 12 month(s) (P<0.01). Maximum urine flow rate (6.0 to 17.2 mL/s, P<0.01), PVR (75.0 to 30.3, P<0.01) and prostatic volume (65.0 to 38.1 mL, P<0.05) were significantly improved 12 months after the operation. Recurrent urinary retention (n=2) and urethrorectal fistula (n=1) occurred at the 15(th) postoperative day. The duration of the HIFU prostate ablation was 25-90 min. The mean time for an indwelling catheter was 3-19 days. These data demonstrate that treatment of BPH with Sonablate-500 HIFU is safe and effective.

PURPOSE: We have evaluated the patterns of diagnostic and treatment practices for benign prostatic hyperplasia (BPH) in a country that does not have country-specific clinical practice guidelines. MATERIALS AND METHODS: Probability samples were taken from the Korean Urological Association Registry of Physicians, and randomly sampled Korean urologists were asked to complete a questionnaire. The survey explored practice characteristics and attitudes, as well as diagnostic and treatment strategies, for the management of BPH. RESULTS: Of the 850 questionnaires sent, 302 were returned, and 277 of those were included in the final analysis (response rate 32.6%). For the initial evaluation, most urologists routinely used digital rectal examinations (DRE) and urinalysis. Uroflowmetry was used 34.7% of the time. Pressure-flow studies were rarely done. Symptom assessment was used in only 46.9% of cases. In addition, a significant number (58.8%) reported that treatment decisions were not based on the symptom questionnaire. Before surgery, almost all urologists routinely used DRE, urinalysis, and prostate-specific antigen tests. Of the respondents, 55.6% and 41.9% had prescribed alpha- blockers and alpha-blockers with 5-alpha reductase inhibitors, respectively. 81.2% of urologists perceived that selective alpha-blockers are different in terms of efficacy, and 82.7% felt that they differed in safety. Most respondents prescribed 5-alpha reductase inhibitors based on the prostate size. CONCLUSION: These data provide a picture of current practices regarding the management of BPH in Korea. The diagnostic and treatment practices for BPH do not follow published guidelines. Our findings ask the question "How influential are international guidelines, and do they really affect patient management in countries that do not have country-specific guidelines?"

PURPOSE: In Korea, there was no specific guidelines for the management of benign prostatic hyperplasia (BPH). We reviewed the practice patterns of Korean urologists in the management of BPH and aimed to describe the need to develop specific guidelines. MATERIALS AND METHODS: A probability sample was taken from the Korean Urological Association Registry of Physicians, and a structured questionnaire, that explored practice patterns in the management of BPH, was mailed to a random sample of 251 Korean urologists. RESULTS: For the initial evaluation of BPH, most urologists routinely performed prostatic specific antigen (PSA) (96.4%), digital rectal exam (94.4%), international prostate symptom score (IPSS) (83.2%) and transrectal ultrasound (79.2%). Symptom assessment (36.4%) followed by transrectal ultrasound of prostate (TRUS) (20.0%) was considered as the most important diagnostic examination affecting the decision about individual treatment options. Almost all urologists (92.2%) chose medical treatment as the first-line treatment option for uncomplicated BPH with moderate symptoms. Of the respondents, 57.2% had prescribed alpha blocker and 41.6% alpha blocker plus 5-alpha reductase inhibitors as the medical treatment option for BPH. The prescription of 5-ARIs was dependent on the size of the prostate and the severity of symptoms. CONCLUSION: The results of our current survey provide useful insight into variations in the clinical practice of Korean urologists. They also indicate the need to develop further practical guidelines based on solid clinical data and to ensure that these guidelines are widely promoted and accepted by the urological community.

PURPOSE: We assessed whether weight reduction is an effective intervention for the management of lower urinary tract symptoms (LUTS) and investigated the relationship between obesity and LUTS. MATERIALS AND METHODS: This was a prospective randomized controlled trial that enrolled obese men older than 50 years with LUTS. The study period was 52 weeks. All patients received standardized alpha-adrenergic blocker therapy for the treatment of benign prostatic hyperplasia (BPH) during the run-in period. Patients were randomized to receive either a standardized prerecorded video program on the general principle of weight reduction or a comprehensive weight reduction program. Patients were assessed at different time points with symptom assessment, uroflowmetry, transrectal ultrasound, and metabolic assessment. RESULTS: Sixty-five patients were allocated to each study arm. After the study period, no significant difference in weight reduction was found between the two arms. When the pre- and postintervention parameters were compared, none were statistically different between the 2 arms, namely nocturia, International Prostate Symptom Score, quality of life assessment, and uroflowmetry parameters. When the whole study population was taken as a single cohort, these parameters were also not significantly different between the group with a body mass index of 25 to <30 kg/m2 and the group with a BMI of 30 to 35 kg/m2. CONCLUSIONS: We found no association between obesity and LUTS. This could have been due to the less marked weight difference in our cohort. Whereas weight reduction may be an effective measure to improve LUTS, the implementation of a successful program remains a challenge.

PURPOSE: In order to gain insight into the physicians' awareness of and attitude towards management of overactive bladder (OAB) in males, we performed a nationwide survey of the current strategies that urologists use to diagnose and manage OAB in male patients. MATERIALS AND METHODS: A probability sample was taken from the Korean Urological Association Registry of Physicians, and a random sample of 289 Korean urologists were mailed a structured questionnaire that explored how they manage benign prostatic hyperplasia (BPH). RESULTS: A total of 185 completed questionnaires were returned. The consent rate in the survey was 64.5%. Eighty-one (44%) urologists believed that of all males with lower urinary tract symptoms (LUTS), 20% or more had OAB and 72 (39%) believed that 10-20% had OAB. Half of the urologists surveyed believed that the most bothersome symptom in male OAB patients was nocturia. Seventy-three percent of respondents reported that they prescribed alpha blockers with anticholinergics for first line management, while 19% of urologists prescribed alpha blocker monotherapy but not anticholinergics for OAB patients. Though acute urinary retention (AUR) was considered the anticholinergic adverse event of most concern, the most frequently observed adverse event was dry mouth (95%). CONCLUSION: The present study provides insights into urologist views of male OAB. There is a discrepancy between the awareness of urologists and actual patterns of diagnosis and treatment of male OAB. This finding indicates the need to develop further practical guidelines based on solid clinical data.

8.Voiding Dysfunctions in Primary Care Practices.
Journal of the Korean Medical Association 2005;48(8):744-754
The availability of new urologic medications has made it possible to manage a variety of urologic disorders successfully in a primary care setting. As a result, primary care physicians(PCPs) need to be familiar with the terminology and screening instruments used by urologists to decipher and categorize urologic symptoms. PCPs are often responsible for the treatment of lower urinary tract symptoms and benign prostatic hyperplasia(BPH). Evolving strategies of management include utilization of both symptom-modifying treatment and disease-modifying treatment. Alphablockers excellently provide symptomatic treatment, but do not alter long-term disease progression. 5-alpha reductase inhibitors can reduce the need for surgical intervention and the incidence of acute urinary retention. The combination of alphablockers and 5-alpha reductase inhibitors would be the choice of therapy in some patients, typically those with large prostate glands indicative of disease progression. Overactive bladder(OAB) is defined as urinary urgency with or without urge incontinence, usually with frequency and nocturia, in the absence of a pathologic or metabolic condition that can explain these symptoms. The diagnosis of OAB should be made after a careful history taking, physical examination, laboratory evaluation, and use of tools such as voiding diaries. Anticholinergic agents are the first choice for drug therapy. Treatment that couples drug therapy with behavioral techniques aimed at modifying abnormal voiding patterns may provide the best outcomes in many patients with OAB. There are situations for referring patients to urologists for more detailed evaluation and management, including when the PCP has a lack of interest in or sufficient knowledge about lower urinary tract symptoms and if the patient shows a poor response to prior noninvasive therapy, requiring in-depth investigation.

AIMTo describe an unusual symptom of benign prostatic hyperplasia (BPH).
METHODSA patient presented to our urology clinic having experienced post-coital gross hematuria for 2 years. He had not experienced lower urinary tract symptoms (LUTS). A series of examinations were performed to determine the source of bleeding.
RESULTSThe prostate was defined as the active bleeding source responsible for the patient's post-coital hematuria. Endoscopic fulguration did not alleviate the symptom. The use of dutasteride, a dual inhibitor of 5alpha-reductase, solved the problem.
CONCLUSIONThis study reports for the first time that post-coital gross hematuria is one of the clinical presentations of BPH, which can be successfully treated with 5alpha-reductase inhibitor.

PURPOSE: To compare the current management of benign prostatic hyperplasia (BPH) by urologists and nonurologists by use of Korean nationwide health insurance data. MATERIALS AND METHODS: We obtained patient data from the national health insurance system. New patients diagnosed with BPH in 2009 were divided into two groups depending on whether they were diagnosed by a urologist (U group) or by a nonurologist (NU group). RESULTS: A total of 390,767 individuals were newly diagnosed with BPH in 2009. Of these, 240,907 patients (61.7%) were in the U group and 149,860 patients (38.3%) were in the NU group. The rate of all initial evaluation tests, except serum creatinine, was significantly lower in the NU group. The initial prescription rate was higher in the U group, whereas the prescription period was longer in the NU group. Regarding the initial drugs prescribed, the use of alpha-blockers was common in both groups. However, the U group was prescribed combination therapy of an alpha-blocker and 5-alpha-reductase inhibitor as the second choice, whereas the NU group received monotherapy with a 5-alpha-reductase inhibitor. During the 1-year follow-up, the incidence of surgery was significantly different between the U group and the NU group. CONCLUSIONS: There are distinct differences in the diagnosis and treatment of BPH by urologists and nonurologists in Korea. These differences may have adverse consequences for BPH patients. Urological societies should take a leadership role in the management of BPH and play an educational role for nonurologists as well as urologists.
