Anatomical endoscopic enucleation of the prostate (AEEP) differs from other endoscopic modalities for bladder outlet obstruction (BOO) because it extracts the whole benign prostatic hyperplasia component. AEEP has been launched for almost 40 years as a first-line treatment method for BOO regardless of prostate size according to several guidelines. However, it remains underperformed worldwide. In this review article, we elaborate on the advantages and disadvantages of AEEP compared to other surgical modalities for BOO to investigate its efficacy and safety as a gold standard surgical management option for males with BOO.

Benign prostatic hyperplasia (BPH), which is the most common disorder in elderly men, involves androgenic hormone imbalance with chronic inflammation that causes imbalance between cell apoptosis and cell proliferation. As the root cause of the BPH remains unclear and synthetic drugs for treatment of BPH have undesirable side effects, the development of effective alternative medicines has been considered. Chinese Skullcap has been considered natural remedy to treat pyrexia, micturition disorder and inflammation. Although skullcap has effective properties on various diseases, the effects and molecular mechanism of Skullcap on BPH are not fully understood. Therefore, in this study, we evaluated the efficacy of Chinese Skullcap root extract (SRE) in testosterone-induced BPH rats. Compared with the untreated group, the SRE treatment group suppressed pathological alterations, such as prostate growth and increase in serum dihydrotestosterone and $5{\alpha}$-reductase levels. Furthermore, SRE significantly decreased the expression of androgen receptor and proliferating cell nuclear antigen. SRE also restored Bax/Bcl-2 balance. These effect of SRE was more prevalent than commercial $5{\alpha}$-reductase inhibitor, finasteride. Taken together, we propose that SRE suppresses abnormal androgen events in prostate tissue and inhibits the development of BPH by targeting inflammation- and apoptosis-related markers. These finding strengthens that SRE could be used as plant-based $5{\alpha}$-reductase inhibitory alternative.

Objectives: Very limited previous research has investigated the utility weights of prostate-related diseases in the general population in Korea. The purpose of this study was to calculate the utility of prostate-related health states in the Korean general public using the standard gamble (SG) method. Methods: Seven health states for hypothetical prostate cancers, 1 for benign prostate hyperplasia, and 1 for erectile dysfunction were developed based on patient education material and previous publications. In total, 460 responses from the Korean general population were used to analyze the utility of prostate-related health states. Computer-assisted personal interviews were conducted, and utility values were measured using a visual analogue scale (VAS) and SG. Mean utility values were calculated for each prostate-related health state. Results: The mean utility values of prostate cancer derived from SG ranged from 0.281 (metastatic castration-refractory prostate cancer) to 0.779 (localized prostate cancer requiring prostatectomy). The utility value of benign prostate hyperplasia was 0.871, and that of erectile dysfunction was 0.812. The utility values obtained using the SG method in all conditions were higher than the values obtained by VAS. There were no significant demographic variables affecting utility values in multivariate analysis. Conclusions: Our findings might be useful for economic evaluation and utility calculation of screening and interventions for prostate-related conditions in the general population.

Morphometry of nuclei of the benign and malignant prostatic lesions was performed to study the relationship between nuclear size and shape and the prognosis of prostatic adenocarcinoma fifty one cases of prostatic adenocarcinoma and 13 cases of benign prostatic hyperplasia were included to evaluate area, perimeter, Dmax, Dmin, and 5 form factors of the nuclei by image analyzer(Zeiss Ibas 2000) using hematoxylin-eosin stained slides. All analytic factors of nuclear size and shape were significantly different between benign lesions and adenocarcinomas. Increased nuclear size was associated with nuclear irregularity, presence of metastasis, advanced clinical stage, and high Gleason's grade and score of prostatic adenocarcinoma. On Kaplan-Meier method, survival was decreased with older age, no hormonal treatment, stage D, high Gleason's grade and stage as well as with larger size and irregular shape of the nuclei in conclusion, morphometry of nuclei of the prostate can be a helpful tool to differentiate between be nign and malignant lesions. Nuclear morphology is thought to be associated with prognosis of prostatic adenocarcinoma.

Pseudohyperplastic prostatic adenocarcinoma is a rare histologic variant of prostatic adenocarcinoma that resembles benign nodular hyperplasia. Immunohistochemistry can verify the absence of basal cells, but it is frequently admixed with conventional adenocarcinoma. Because fine needle aspiration cytology is rarely performed in primary prostatic adenocarcinoma, the cytology of the pseudohyperplastic variant has not been described. We experienced a case of metastatic pseudohyperplastic adenocarcinoma in a pulmonary nodule of 75-year-old man. The cytologic smear was mostly composed of large, flat sheets with elongated branching papillae in a clean background. The sheets showed a well-defined honeycomb appearance of tall columnar, regularly arranged monotonous cells with little cytologic atypia. In subsequent prostatic biopsy, pseudohyperplastic variants were identified together with conventional adenocarcinoma of Gleason's grade 3 and 4. The cytologic features of pulmonary nodules were identical to those of pseudohyperplastic components of prostatic adenocarcinoma.

Obejectives : To investigate the clinical effect of electroacupuncture and bee venom acupuncture for benign prostatic hyperplasia(BPH) symptoms. Methods : Among 39 outpatients who were treated at a BPH clinic, 8 were finally selected for analysis by charts-review, retrospectively. They were treated by electroacupuncture and bee venom acupuncture more than 3 times. We estimated the effectiveness of the treatments by using the International Prostate Symptom Score (IPSS) questionnaire and checking their nocturia frequency. On the basis of these variables, we analyzed the statistical significations of symptom improvements. Results : Among 8 patients, the IPSS and nocturia frequency showed significant improvement after the final treatment compared with baseline (P = .0078, P = .0078). The IPSS significantly decreased even after the 1st treatment and also after the 2nd treatment compared with the baseline (P = .0078, P = .0078). The IPSS at post final-treatment, post 1st- and post 2nd treatment also showed significant improvement compared with IPSS at baseline in 6 severe symptomatic patients(P = .031, P = .031, P = .031). Nocturia frequency decreased after the 1st treatment compared with baseline and showed significant improvement between baseline and post 2nd treatment (P = .0078). Conclusions : In a retrospective and cross-sectional study investigating the clinical effects of electroacupuncture and bee venom acupuncture on BPH, these treatments proved to have significant therapeutic effects, particularly for various symptoms involving frequent nocturia.

With the improvement in the standard of living and extension of life expectancy, the incidence of prostate diseases has increased yearly, thus becoming a serious disease affecting the health of men. The extract mixture of Cornus officinalis and Stauntonia hexaphylla leaves is a developed functional food formula to improve prostate health. This study developed a simultaneous analytical method of bioactive compounds for quantifying the mixture of Cornus officinalis and S. hexaphylla leaves using high-pressure liquid chromatography-ultraviolet (HPLC-UV). HPLC analytical condition was performed on a Hector C₁₈ column with a mobile phase of 0.1 % formic acid in water (A) and 0.1 % formic acid in acetonitrile (B) under the following gradient conditions: 0-50 min, 12 %-40 % (B) at a flow rate of 1.0 mL/min. Meanwhile, this method was validated properly and successfully used to quantify the bioactive components of morroniside and hederacoside D in 20 sample batches and assess the quality of different ages and seasons of S. hexaphylla leaves. The result showed that the content of morroniside in the extract mixture of Cornus officinalis and S. hexaphylla leaves ranged from 1.38-1.62 mg/g, and the hederacoside D ranged from 28.42-32.02 mg/g, suggesting that this novel analytical method will be suitable for the quality control of the extract mixture to improve benign prostatic hyperplasia.

Objectives : This study aimed to evaluate the randomized controlled clinical trials (RCTs) analyzing the effectiveness of Chuna manual therapy (CMT) for benign prostatic hyperplasia (BPH). Methods : Among the literature published until May 2020, a literature search was carried out using 10 electronic databases using related keywords to identify all RCTs that applied CMT for the treatment of BPH. The Cochrane risk of bias tool was used to assess the methodological quality of each RCT. Results : Five RCTs met our inclusion criteria and were included in the analysis. These studies showed that CMT had no positive results compared to herbal medication. However, positive results were shown in terms of an increased efficacy rate, reduced international prostate symptom scores, and increased maximum flow rate when CMT was combined with acupuncture or herbal medication. Conclusions : Based on the analysis, this review has limited evidence of CMT being beneficial in the treatment of BPH. Therefore, further investigation is required using well-designed RCTs to support the effectiveness of CMT and to obtain higher evidence.

Benign prostatic hyperplasia(BPH) is a common disease among male. However, its cause and treatment are not known and it is easy to relapse to the patients again after some treatment. Chinese has got an active research on BPH of traditional Chinese medicine. We researched the Chinese clinical papers from 2000 to 2014. After translating those papers, we analyzed total 45 papers by classifying those according to frequently used prescriptions, differentiation of symptoms, signs, addition and subtraction of each medicine and the quantity of frequently used medicines. Through this study it was to provide evidence in the diagnosis and treatment of BPH. The prescription of BPH was classified according to its stage. Mainly damp heat patterns(濕熱型) induce dysuria, Qi-stagnation and blood stasis patterns(氣滯血瘀型) induce pain, While Kidney deficiency patterns(腎虛型) induce sexual function disorder. This analysis report would be able to provide the basis of taking a research on BPH. In addition, it could be applied on a stereotype of BPH as well as a variety of symptoms with frequently used prescription and addition and subtraction of each medicine.
