OBJECTIVES: To compare the efficacy and safety of silodosin versus tadalafil for treating lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH). METHODS: After informed consent, patients with LUTS/BPH were randomized in a 1:1 ratio to receive silodosin 8 mg/day or tadalafil 5 mg/day for 8 weeks (Period 1). Patients treated with tadalafil entered an exploratory phase and received silodosin or tadalafil for another 8 weeks. The primary efficacy endpoint was the change in the total International Prostate Symptom Score (IPSS) with Period 1 treatment...

As estrogen receptor β(-/-) (ERβ(-/-)) mice age, the ventral prostate (VP) develops increased numbers of hyperplastic, fibroplastic lesions and inflammatory cells. To identify genes involved in these changes, we used RNA sequencing and immunohistochemistry to compare gene expression profiles in the VP of young (2-mo-old) and aging (18-mo-old) ERβ(-/-) mice and their WT littermates. We also treated young and old WT mice with an ERβ-selective agonist and evaluated protein expression. The most significant findings were that ERβ down-regulates androgen receptor (AR) signaling and up-regulates the tumor suppressor phosphatase and tensin homolog (PTEN)...

OBJECTIVES: Benign prostatic hyperplasia (BPH) commonly affects men above 40 years old. The progression of BPH is often accompanied with lower urinary tract symptoms (LUTS) that can significantly affect the quality of life of the patients. Serenoa repens (saw palmetto) is a popular herbal remedy indicated for LUTS/BPH. We reviewed the current research on the efficacy of S. repens on LUTS/BPH as a monotherapy as well as combination therapies. DESIGN: Non-systematic searches were performed in PubMed for human studies and systematic reviews on the topic...

Holmium Laser Enucleation of the Prostate (HoLEP) is a safe and effective treatment option for benign prostatic hyperplasia. However, in some cases, it can lead to life-threatening complications. In particular, morcellation of the resected adenoma may be a very dangerous procedure when performed without clear visualization. We describe the first reported case of a vesicosigmoid fistula secondary to a morcellation injury during HoLEP.

INTRODUCTION: Epidemiological studies suggest a link between the symptoms of lower urinary tract (LUTS) caused by benign prostatic hyperplasia (BPH) and erectile dysfunction (ED). Increasing expected period of life, justify the interest of establishing correlations LUTS / BPH and ED in order to find more efficient ways of treating these pathologies. GOAL: The objective was to evaluate the correlation of symptoms in LUTS/BPH with the degree of ED. PATIENTS AND METHODS: The study was conducted as a prospective study which involved males aged 40-60 yr with present symptoms of LUTS/BPH...

Prostate Specific Antigen (PSA) is the most commonly used serum marker for prostate cancer (PCa), although it is not specific and sensitive enough to allow the differential diagnosis of the more aggressive tumors. For that, new diagnostic methods are being developed, such as PCA-3, PSA isoforms that have resulted in the 4K score or the Prostate Health Index (PHI), and PSA glycoforms. In the present study, we have compared the PHI with our recently developed PSA glycoform assay, based on the determination of the α2,3-sialic acid percentage of serum PSA (% α2,3-SA), in a cohort of 79 patients, which include 50 PCa of different grades and 29 benign prostate hyperplasia (BPH) patients...

The differential diagnosis of benign and malignant changes in the prostate presents still definite difficulties; the antibody panel existing for these purposes is imperfect. Fatty acid synthase (FASN) is an androgen-regulated enzyme required for de novo lipogenesis. A number of studies have noted increased expression of the gene encoding this protein in tumors and precancerous lesions of different locations. AIM: Тo estimate the diagnostic value of analyzing the expression of FASN in prostate neoplasias...

Abdominal straining associated with voiding dysfunction or constipation has traditionally been associated with the development of abdominal wall hernias. Thus, classic general surgery dictum recommends that any coexistent bladder outlet obstruction should be addressed by the urologist before patients undergo surgical repair of a hernia. While organ-confined prostate cancer is usually not associated with the development of lower urinary tract symptoms, a modest proportion of patients treated with radical prostatectomy may have coexisting benign prostatic hyperplasia with elevated symptom scores and hernias may be incidentally detected at the time of surgery...

We report a case of primary diffuse large B-cell lymphoma of the prostate in a 54-year-old Caucasian male who presented with urinary retention and benign prostatic hyperplasia. We discuss the rare presentation of this disease and its clinicopathologic features and review the literature for up-to-date information on the diagnosis and clinical management. Despite the low incidence of lymphoma involving the prostate gland, it should always be considered as part of the differential diagnosis in cases of prostate gland enlargement with urinary tract obstructive symptoms resistant to medical therapy...

Several studies have implicated estrogen and the estrogen receptor (ER) in the pathogenesis of benign prostatic hyperplasia (BPH); however, the mechanism underlying this effect remains elusive. In the present study, we demonstrated that estrogen (17β-estradiol, or E2)-induced activation of the G protein-coupled receptor 30 (GPR30) triggered Ca(2+) release from the endoplasmic reticulum, increased the mitochondrial Ca(2+) concentration, and thus induced prostate epithelial cell (PEC) apoptosis. Both E2 and the GPR30-specific agonist G1 induced a transient intracellular Ca(2+) release in PECs via the phospholipase C (PLC)-inositol 1, 4, 5-triphosphate (IP3) pathway, and this was abolished by treatment with the GPR30 antagonist G15...
