The aim of this study was the development of quantitative assessment of prostatic calcifications at prostatic ultrasound examination by the use of an image analyzer.
A group of 82 patients was evaluated by medical history, physical, and transrectal ultrasound examination. Patients had a urethral swab, a 4-specimen study and culture of the seminal fluid. Patients were classified according to National Institute of Diabetes and Digestive and Kidney Diseases/National Institutes of Health. Subjective symptoms were scored by Chronic Prostatitis Symptom Index (CPSI) questionnaire. Ultrasound images were analyzed by the digital processing software Image J to quantitatively assess the presence of calcifications.
Computer-assessed calcified areas were significantly higher in chronic bacterial prostatitis (n = 18; group II; 6.76 ± 8.09%) than in the chronic pelvic pain syndrome group IIIa (n = 26; 2.07 ± 1.01%) and IIIb (n = 38; 2.31 ± 2.18%). The area of calcification of the prostate was significantly related to the CPSI score for domains of micturition (r = 0.278, p = 0.023), Prostatic Specific Antigen values (r = 0341, p = 0.005), postvoiding residual urine (r = 0.262, p = 0.032), total prostate volume (r = 0.592, p = 0.000), and adenoma volume (r = 0.593; p = 0.000).
The presence of calcifications is more frequently observed in patients with chronic bacterial prostatitis and is related to urinary symptoms.
本研究的目的是通过使用图像分析仪在前列腺超声检查中对前列腺钙化进行定量评估。
通过病史、体格检查和经直肠超声检查对一组82例患者进行评估。患者进行尿道拭子检查、4标本精液研究及精液培养。根据美国国立糖尿病、消化和肾脏疾病研究所/美国国立卫生研究院对患者进行分类。主观症状采用慢性前列腺炎症状指数（CPSI）问卷评分。超声图像通过数字处理软件Image J进行分析，以定量评估钙化的存在情况。
计算机评估的钙化面积在慢性细菌性前列腺炎患者（n = 18；II组；6.76±8.09%）中显著高于慢性盆腔疼痛综合征IIIa组（n = 26；2.07±1.01%）和IIIb组（n = 38；2.31±2.18%）。前列腺钙化面积与排尿领域的CPSI评分（r = 0.278，p = 0.023）、前列腺特异性抗原值（r = 0.341，p = 0.005）、排尿后残余尿量（r = 0.262，p = 0.032）、前列腺总体积（r = 0.592，p = 0.000）及腺瘤体积（r = 0.593；p = 0.000）显著相关。
慢性细菌性前列腺炎患者中钙化的存在更为常见，且与泌尿症状相关。
