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...

Involvement of the prostate gland, as an early extra-nodal manifestation of a hematologic disease, or as a secondary infiltration is rare. Even rarer is the acute urinary retention due to infiltration by lymphocytes and simultaneously enlarged prostate. We present a case of a 61 years old male patient with a history of chronic lymphocytic leukemia, who was under oncological follow-up with no active treatment and had typical lower urinary tract symptoms due to benign prostatic hyperplasia and was receiving 5-alpha reductase inhibitor...

Kidney ultrasound is one of the basic procedures in the practice of a urologist. Apart from the location and the size, description of renal morphology should contain the thickness of the anterior lip parenchyma in a transverse section and the location of possible narrowings. Uneven outline of the kidney is a sign of past inflammatory conditions. In the case of the pelvicalyceal system dilation, it is advised to specify the dimensions of the pelvis and calyces. Convex shape of the calyces proves elevated pressure within the pelvicalyceal system...

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)...

BACKGROUND: Despite significant developments in transurethral surgery for benign prostatic hyperplasia, simple prostatectomy remains an excellent option for patients with severely enlarged glands. The objective is to describe our results of robot-assisted simple prostatectomy (RASP) with a modified urethrovesical anastomosis (UVA). METHODS: From May 2011 to February 2014, RASP with UVA was performed in 34 patients by a single surgeon (O.C.) using the da Vinci S-HD surgical system...

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...
