Objective: To analyze the chemical components of prostatic calculi. Method: An infrared automatic analyzer was used to determine the chemical components of prostatic calculi from 86 patients, and the causes of formation and related clinical data were examined. Results: Magnesium ammonium phosphate and carbapatite were found in 84.9% of calculi, and the difference in the comparison with urinary ...

bstructive uropathy is a common clinical problem, and urethral calculi constitute the least common form of calculous disease leading to obstructive uropathy. Urethral calculi may originate anywhere in the urinary tract, usually the bladder, and then migrate to the urethra. The clinical presentation is variable. Patients may have acute retention, dysuria, or a weak urine stream.1 Sonography is a...

Prostatic parenchymal calculi are common, usually incidental, findings on morphological examinations. They are typically asymptomatic and may be present in association with normal glands, benign prostatic hyperplasia, and prostate cancer. However giant prostatic calculi are rare. Less than 20 cases have been reported in the literature. We present the case of a 35-year-old man with two giant pro...

Identification of prostatic calculi is an important basis for determining the tissue origin. Computation-assistant diagnosis of prostatic calculi may have promising potential but is currently still less studied. We studied the extraction of prostatic lumina and automated recognition for calculus images. Extraction of lumina from prostate histology images was based on local entropy and Otsu thre...

INTRODUCTION We present a case of Alkaptonuria (AKU) presented with severe lower urinary tract symptoms (LUTS) secondary to extensive prostatic calculi deposited in the para prostatic diverticulum. Prostatic calculi are seen in chronic prostatitis, chronic pelvic pain syndrome and benign prostate hyperplasia; however, in patients with AKU, prostatic calculi and/or calcifications are more extens...

Purpose: To examine the clinical implications of prostatic calculi in terms of links to chronic pelvic pain, voiding and sexual functions. Methods: 60 adult males were recruited for this study. The parameters recorded were: age, weight, height, Body Mass Index (BMI) calculated as the weight in kilograms divided by the square of the height in meters, Waist Circumference (WC), Lower Urinary Tract...
