OBJECTIVE: The purpose of this study is to correlate the findings of peripheral hypoechoic rim, seen at transrectal ultrasonography (TRUS) in chronic prostatitis patients, with the histopthologic findings. MATERIALS AND METHODS: Seven patients with pathologically proven chronic prostatitis were involved in this study. The conspicuity of the peripheral hypoechoic prostatic rim, seen at TRUS, was prominent and subtle, and to determine its histopathologic nature, the microscopic findings were reviewed. RESULTS: In five of seven cases (71%), TRUS demonstrated a prominent peripheral hypoechoic rim. Microscopic examination revealed that inflammatory cell infiltration of prostatic glandular tissue was severe in three cases (42.9%), moderate in two (28.6%), and minimal in two (28.6%). In all seven cases, the common histopathologic findings of peripheral hypoechoic rim on TRUS were loose stromal tissues, few prostatic glands, and sparse infiltration by inflammatory cells. CONCLUSION: The peripheral hypoechoic rim accompanying prostatic inflammation and revealed by TRUS reflects a sparsity of prostate glandular tissue and is thought to be an area in which inflammatory cell infiltration is minimal.

2.A Diagnostic Significance of Ultrasonography in Prostatic Disease.
Korean Journal of Urology 1985;26(6):609-614
From its size, location and structure, the prostate is one of the most suitable organs for the diagnostic application of ultrasound. Transrectal ultrasonography with transrectal linear array probe was per. formed in 19 controls and 36 patients with prostatic disease to evaluate the size and morphology of prostate. The following results were obtained: 1. The average values of maximum anteroposterior, superiorinferior and transverse diameter obtained from ultrasonograms were 2.2O+/-0.30cm, 3.38+/-0.35cm, 4.18+0.35cm in control group; 3.16+/-0.78 cm, 4.79+/-0.84 cm, 5.13+/-0.62cm in BPH; 3.40+/-0.84cm, 5.25+ 1.95cm, 5.73+/-1.16cm in prostatic cancer. 2. In a comparison of sonography and x-ray for detecting prostatic calculi, the detection rate of sonography (54.5 %) was higher than x-ray (25.5%). 3. Diagnostic accuracy of sonography was 88% in BPH and 100% in prostatic cancer. 4. Ultrasonographic findings in BPH were enlarged in size, homogeneity in echo pattern and all capsular echoes are continuous. In prostatic cancers, which have mixed echo pattern and capsule is thick with discontinuity. 5. Transrectal sonography is especially useful in estimating prostatic size and in detecting pathology such as BPH, prostatic cancer, prostatitis and abscess.

OBJECTIVETo assess the application value of transrectal ultrasound (TRUS) in the diagnosis of chronic prostatitis.
METHODSTRUS and examination of prostatic secretion (EPS) were used in the diagnosis of 3 500 cases of chronic prostatitis from September, 2000 to May, 2006.
RESULTSLower resonance of the inner gland, low-level echo, uneven echo light spots, incomplete outlines and unsmooth borderlines were found in 2279 cases (65.1%), and the enlarged prostate in 1 084 cases (31.0%), with clear integrated amicula and enhanced echogenic spots at the juncture of the external and inner gland. No obvious changes were noted in 137 cases (4.0%), and in another 391 cases (11.2%) were detected alteration of the acoustic image of cystospermitis and blurred margins and uneven echoes of the seminal vesicle. The WBC count in EPS was < 10/HP in 132 cases (3.8%), 10-19/HP in 2 156 cases (61.6%) and > or =20/HP in 1212 cases (34.6%).
CONCLUSIONTRUS, as a diagnostic means for chronic prostatitis, can be easily performed and causes little pain and therefore is readily accepted by patients. Combined with EPS, TRUS can provide more definite diagnostic evidence, and for those who are afraid of pain and reject EPS, it is a desirable alternative in the diagnosis of chronic prostatitis.

Objective:
To investigate the effects of transrectal ultrasound conductance (TRUSC)-guided administration of traditional Chinese medicine on histological prostatitis in men with small-size BPH and low urinary tract symptoms (LUTS) after transurethral resection of the prostate (TURP).
METHODS:
This study included 167 BPH patients without surgical contraindications. We randomized the patients into an experimental group (n = 84) and a control group (n = 83), with no statistically significant differences between the two groups in age, prostate volume, International Prostate Symptom Score (IPSS), and quality of life (QoL) (P >0.05). The patients of the experimental group received TRUSC-guided administration of traditional Chinese medicine, qd, for 7 days before TURP, while those of the control group underwent TURP only. After treatment, we compared the results of postoperative pathological examination of the prostate tissue, the histological grade of inflammation, IPSS, and QoL scores between the two groups of patients.
RESULTS:
In the experimental group, there were 12 cases of non-inflammation (14.3%), 43 cases of mild inflammation (51.2%), 28 cases of moderate inflammation (33.3%), and 1 case of severe inflammation (1.2%), as compared with 8 cases of non-inflammation (9.6%), 28 cases of mild inflammation (33.7%), 45 cases of moderate inflammation (51.8%), and 2 cases of severe inflammation (2.4%) in the control group (P <0.05). Compared with the baseline, both the experimental and control groups showed significant improvement at 4 weeks after surgery in IPSS (22.20±4.14 vs 4.26±2.64 and 23.05±4.11 vs 7.02±4.15, P <0.05) and QoL scores (4.33±0.83 vs 1.25±1.64 and 4.25±0.91 vs 2.05±1.95, P <0.05).
CONCLUSIONS
TRUSC-guided administration of traditional Chinese medicine can significantly alleviate histological inflammation and improve QoL in men with small-size BPH and LUTS after TURP.
