A Nomogram Based on a TRUS Five-Grade Scoring System for the Prediction of Prostate Cancer and High Grade Prostate Cancer at Initial TRUS-Guided Biopsy.

: To evaluate the efficacy of transrectal ultrasound five-grade scoring system (TRUS-5) in predicting prostate cancer (PCa) and high grade PCa (HGPCa), compared with TRUS two-grade scoring system (TRUS-2), and establish a TRUS-5 based nomogram for the prediction of PCa and HGPCa at initial biopsy (IPBx). : Data were collected from 862 men who underwent initial TRUS-guided 12-core prostate biopsy. Age, prostate-specific antigen (PSA), percent free PSA, digital rectal examination (DRE), prostate volume (PV), PSA density (PSAD) and TRUS findings were included in the analysis.

G protein‑coupled estrogen receptor/miR‑148a/human leukocyte antigen‑G signaling pathway mediates cell apoptosis of ovarian endometriosis.

The focus of the current study was a G protein‑coupled estrogen receptor (GPER)/microRNA (miR)‑148a/human leukocyte antigen‑G (HLA‑G) signaling pathway in ovarian endometriosis. Reverse transcription‑quantitative polymerase chain reaction was performed to analyze the changes in miR‑148a expression. A MTT assay, flow cytometry and caspase‑3/9 activity assays were performed to analyze cell proliferation, apoptosis and caspase‑3/9 activity levels, respectively.

The utility and limitations of contrast-enhanced transrectal ultrasound scanning for the detection of prostate cancer in different area of prostate.

Objective: To evaluate the ability of contrast-enhanced transrectal ultrasound (CETRUS) scanning for prostate cancer detection in different area, compared with conventional transrectal ultrasound (TRUS).

Methods: 228 patients underwent TRUS-guided prostate biopsy after examinations of TRUS and CETRUS scanning. Cancer detection between CETRUS and TRUS were compared by patient and by site in different areas (right, left; base, mid-gland, apex).

Influence of serum prostate-specific antigen (PSA) level, prostate volume, and PSA density on prostate cancer detection with contrast-enhanced sonography using contrast-tuned imaging technology.

Objectives: The purpose of this study was to evaluate the influence of the serum prostate-specific antigen (PSA) level, prostate volume, and PSA density on prostate cancer detection with contrast-enhanced sonography using contrast-tuned imaging technology compared with baseline imaging (combination of grayscale and power Doppler imaging).

Methods: In all, 161 patients were evaluated with grayscale, power Doppler, and contrast-tuned imaging. Biopsy was performed at 10 sites in each patient.

Prediction of early hepatic artery thrombosis by intraoperative color Doppler ultrasound in pediatric segmental liver transplantation.

Early hepatic artery thrombosis (eHAT) after transplantation is associated with a high incidence of graft failure and mortality in pediatric segmental liver transplantation (LT). The evaluation of intraoperative color Doppler ultrasound (CD-US) parameters and their sensitivity and specificity for the prediction of eHAT were important. Pediatric segmental LTs were performed in 49 consecutive patients from October 2006 to December 2010 in our hospital.

Enhancement patterns and parameters of breast cancers at contrast-enhanced US: correlation with prognostic factors.

Purpose: To investigate the correlation between enhancement patterns and parameters of contrast material-enhanced ultrasonography (US) with prognostic factors in breast cancers.

Materials And Methods: The study was approved by the institutional ethics committee, and written informed consent was obtained. Surgical resection specimens of 74 malignant breast lesions in 74 women (mean age, 55 years; age range, 32-78 years) who had undergone contrast-enhanced US were included.

Contrast-enhanced ultrasonography with contrast-tuned imaging technology for the detection of prostate cancer: comparison with conventional ultrasonography.

Unlabelled: Study Type - Diagnostic (exploratory cohort) Level of Evidence 2b What's known on the subject? and What does the study add? The present study was to perform contrast-tuned imaging (CnTI) technology to detect prostate cancer and compare the use of CnTI technology for the detection of prostate cancer with conventional ultrasonography. The preliminary data from our study suggested that targeted biopsy of the prostate with CnTI technology could improve the cancer detection and detect higher grade prostate cancers.

Objectives: To perform contrast-enhanced ultrasonography (CEUS) using contrast-tuned imaging (CnTI) technology to detect prostate cancer.

Value of contrast-enhanced sonography with micro flow imaging in the diagnosis of prostate cancer.

Background: To evaluate the effectiveness of contrast-enhanced sonographic micro flow imaging (MFI) in the diagnosis of prostate cancer.

Methods: A total of 74 patients referred for prostate biopsy were prospectively evaluated with MFI. The abnormalities were categorized into four patterns: pattern 1: indistinct separation between the inner and outer gland; pattern 2: asymmetrical or focally increased enhancement in the outer gland; pattern 3: enhancement with focal defect; pattern 4: enhancement in the outer gland equal to that of the inner gland.

Differential diagnosis of azoospermia and etiologic classification of obstructive azoospermia: role of scrotal and transrectal US.

Purpose: To evaluate the usefulness of scrotal and transrectal ultrasonography (US) in the differential diagnosis of azoospermia and the etiologic classification of obstructive azoospermia.

Materials And Methods: This study was approved by the institutional ethics committee, and all patients provided written informed consent. Between April 2006 and November 2008, 100 infertile men (mean age, 32 years; range, 22-51 years) with azoospermia were evaluated at scrotal and transrectal US, with an emphasis on abnormal US findings of the seminal tract and measurement of testicular volume.
