Benign prostatic hyperplasia (BPH), also known as benign prostatic hypertrophy, is a nonmalignant adenomatous overgrowth of the periurethral prostate gland commonly seen in aging men. Historically, it has been assumed that the pathophysiology of lower urinary tract symptoms in men is the result of bladder outlet obstruction associated with prostate enlargement. Symptoms such as urinary hesitancy, incomplete bladder emptying, dribbling or prolonged urination, nocturia, urinary urgency, and/or urge incontinence are common...

Benign prostatic hyperplasia (BPH) refers to proliferation of smooth muscle and epithelial cells within the transition zone of the prostate. Half of men over 40 develop histologic BPH. About half of men with BPH develop an enlarged prostate gland, called benign prostatic enlargement; among these, about half develop some degree of bladder outlet obstruction. Bladder outlet obstruction and changes in smooth muscle tone and resistance may result in lower urinary tract symptoms, including storage disturbances (such as daytime urinary urgency, frequency, and nocturia) and voiding disturbances (such as urinary hesitancy, weak urinary stream, straining to void, and prolonged voiding)...

Benign prostatic hyperplasia (BPH) the most common condition in aging men is the non malignant enlargement of the prostate gland with increase in numbers of both epithelial and stromal cells within the periurethal transition zone of the prostate. Sources of symptoms in patient with BPH appear to be both static and dynamic component. Management of BPH has undergone a rapid evolution over the past decade to aid men with lower urinary tract symptoms attributed to bladder outlet obstruction. Treatment of clinical BPH aims to improve symptoms, prevent urinary tract infections, avoid renal insult, relief obstruction and improve bladder emptying...

Benign prostatic hyperplasia (BPH) is a common disease in older men that involves the enlargement of the prostate gland. This occurs in response to signal transduction initiated by α-adrenergic receptors (α-ARs). When bound to ligands, α-ARs stimulate the mitogenic extracellular signal-regulated kinases 1 and 2 (ERK) pathway, ultimately promoting stromal and epithelial cell hyperplasia in the prostate. Current knowledge of how α-ARs promote prostate cell growth remains incomplete, and despite decades of research, there is no cure for BPH...

Spontaneous extravasation of urine (SUE) is a rare urologic manifestation. Predisposing conditions of SUE include ureteric calculus, retrograde pyelography, pregnancy, abdominal aorta aneurysm, tumors, or enlargement of the prostate gland. Usually, SUE is a self-limiting condition that mandates differentiaton from other catastrophic conditions of pelviureteric ruptures. Most reported cases of SUE based on urograms are unilateral in presentation. Herein, we report a case of bilateral SUE evident on computed tomography urography in a patient with benign prostatic hyperplasia...

Primary leiomyosarcoma of the prostate (PLSOP) is rare, with less than 200 cases reported so far. PLSOPs present with lower urinary tract symptoms, haematuria, and perineal pain; may or may not be associated with a history of previous treatment for adenocarcinoma of prostate by means of radiotherapy and or hormonal treatment; may afflict children and adult male. Examination may reveal benign enlarged prostate and hard enlarged mass. PLSOPs may be diagnosed by histological examination findings of spindle-shaped carcinoma cells in prostate specimens...

Rationale of prostatic artery embolization (PAE) in the treatment of symptomatic benign prostatic hyperplasia is conventionally believed to include two parts: shrinkage of the enlarged prostate gland as a result of PAE-induced ischemic infarction and potential effects to relax the increased prostatic smooth muscle tone by reducing the number and density of α1-adrenergic receptor in the prostate stroma. This review describes new insights into the likely mechanisms behind PAE, such as ischemia-induced apoptosis, apoptosis enhanced by blockage of androgens circulation to the embolized prostate, secondary denervation following PAE, and potential effect of nitric oxide pathway immediately after embolization...

To date, there is only scarce data on the evaluation of the prostate gland in dogs using computed tomography (CT). The aims of our study were to describe CT features of BPH in dogs and to determine the size of the prostate gland in healthy male dogs and dogs with benign prostatic hyperplasia (BPH) through CT. Additionally, we aimed to compare and establish the most useful parameters for CT measurements of the prostate in patients with BPH. The study population consisted of 20 healthy intact male dogs and 20 male intact dogs with confirmed BPH...

INTRODUCTION: Benign prostatic hyperplasia (BPH) is the most common prostate disease, characterized by benign enlargement of the prostate gland in aging men. Testosterone is said to be the major factor in development of BPH. The relative length of 2nd and 4th digit (2D:4D) is a marker for prenatal androgen exposure. A low 2D:4D ratio is associated with a high prenatal androgen exposure. The main objective of this study was to assess the causal relationship between the 2D:4D ratio and incidence of BPH...

The similarity between some carcinomas and many benign glandular proliferations has been mentioned in the literature for decades. The description of the main histologic features of pseudohyperplastic carcinoma has been very useful in avoiding errors of interpretation, particularly false-negative results. In recent years, we have found some histologic variants of this neoplasm that have not been mentioned previously. In order to classify the different histologic growth patterns and comment on their differential diagnosis, we reviewed the architectural and cytologic features of 34 cases of pseudohyperplastic adenocarcinoma in 2 radical prostatectomies, 4 transurethral resections, and 28 needle biopsies...

The treatments for benign prostate enlargement (BPE), also known as lower urinary tract symptoms secondary to benign prostatic hypertrophy (BPH-LUTS), have evolved significantly over recent years. Where transurethral resection of the prostate (TURP) has been the gold standard surgery for enlarged prostate glands < 80 grams, newer modalities such as laser technology have proliferated with safe and efficacious results. Notably, for prostates larger than 80-100 grams, the surgical options were an open, simple prostatectomy or perhaps a staged TURP...

BACKGROUND: Benign prostatic hyperplasia is a condition occurring in elderly men in which the prostate gland is enlarged, hence the condition also known as benign enlargement of prostate. Benign hyperplasia can lead to both obstructive and irritative symptoms. Transurethral resection of prostate (TURP) still remains the gold standard modality of surgical treatment of obstructive lower urinary tract symptoms due to Benign hyperplasia. OBJECTIVES: The objective of this study was to evaluate the outcomes of TURP in large prostate (>80 grams) in comparison to small prostate (<80 grams) in terms of efficacy, safety and complications...

Benign prostatic hyperplasia (BPH) is one of the most common conditions affecting middle-aged men. This condition can be microscopic, macroscopic, symptomatic, or asymptomatic. Up to 15% to 25% of men aged 50-65 years have lower urinary tract symptoms (LUTS) consisting of nocturia, urgency, frequency, a sensation of not completely emptying the bladder, stop-start urination, straining to urinate, a need to urinate soon after voiding, and weak urinary stream. These symptoms usually are associated with benign enlargement of the prostate gland that is of sufficient severity to interfere with a man's quality of life...

Benign prostatic hyperplasia (BPH), a disease occurring frequently among elderly males, is a slow progressive enlargement of the fibromuscular and epithelial structures of the prostate gland. Dietary factors may influence the prostate and exert an influence on prostatic growth and disease. The current study was undertaken to investigate the protective effect of dietary flaxseed supplementation against testosterone-induced prostatic hyperplasia in male rats. Forty male Wistar rats were divided into 5 groups: (1) untreated control; (2) treatment with testosterone propionate (TP) to induce prostate enlargement; (3) TP-treated group fed a diet containing 5% milled flaxseed; (4) TP-treated group fed a diet containing 10% milled flaxseed; and (5) TP-treated group fed a diet containing 20 ppm finasteride...
