Inherently, brachytherapy is the most conformal radiotherapeutic technique. As an aid to brachytherapy, ultrasonography (USG) serves as a portable, inexpensive, and simple to use method allowing for accurate, reproducible, and adaptive treatments. Some newer brachytherapy planning systems have incorporated USG as the sole imaging modality. Ultrasonography has been successfully used to place applicator and dose planning for prostate, cervix, and anal canal cancers. It can guide placement of brachytherapy catheters for all other sites like breast, skin, and head and neck cancers...

BACKGROUND: Prostate cancer (PCa) is not commonly found in men younger than 50 years of age. However, serum prostate-specific antigen (PSA) concentration has been examined more frequently at a younger age in Asia partially due to an increased awareness of prostate cancer. The purpose of our study was to investigate the efficacy and complication of PSA-triggered transrectal ultrasonography-guided prostate (TRUSP) biopsies. We retrospectively reviewed TRUSP biopsies in young men with elevated PSA concentration in Taipei Veterans General Hospital...

Multiparametric MRI prostate (mp-MRI) is a powerful tool to locate lesions>0.5cm(3) (below this threshold tumor volume, prostate cancers are classified as "insignificant"). The detection rate of the mp-MRI for significant cancers of small volume (0.5-1cm(3)) with a Gleason score≥7 is>85 %. The prostate mp-MRI optimizes the management of cancers classified as low risk of progression by providing aggressive criteria for misclassified lesions, which require an active treatment and enhance the clinicopathological criteria of indolence for subclinical lesions, which can justify of surveillance...

OBJECTIVE: The biopsies of prostate are the reference examination to assert the diagnosis of prostate cancer. Even if the urinary infectious complications are rare thanks to the systematic oral antibiotic prophylaxis, they may still be serious. The SPILF (Society of Infectious Pathology and French language) published in 2014, an important increase of the resistances in fluoroquinolones for Escherichia coli (3 to 25%), whereas this is the most bacterium frequently found in the urinary infections (70-80%)...

Despite the frequent statement that "most men die with prostate cancer, not of it," the reality is that prostate cancer is second only to lung cancer as a cause of death from malignancy in American men. The primary goal during baseline evaluation of prostate cancer is disease characterization, that is, establishing disease presence, extent (local and distant), and aggressiveness. Prostate cancer is usually diagnosed after the finding of a suspicious serum prostate-specific antigen level or digital rectal examination...

Most men with hematospermia or hemospermia (HS) are young (<40 years of age), presenting with transient or episodic HS without other signs or symptoms of disease. The condition is self-limiting in most cases and idiopathic in nature. When a cause can be identified, infections of the urogenital tract are the most common. Imaging does not play a role in this patient population. In older men (>40 years of age), clinical screening for prostate cancer is advised. Furthermore, when HS is persistent or has symptoms, causes include obstruction or stricture at the level of the verumontanum, calcifications or calculi in the prostate, ejaculatory ducts or seminal vesicles, and cysts arising within these structures...

INTRODUCTION: Transrectal rectal ultrasound (TRUS)-guided systematic biopsy is the gold standard for diagnosis of prostate cancer. However, systematic biopsy has high false-negative rate and often misses anteriorly located tumors. Magnetic resonance imaging (MRI)-TRUS fusion biopsy can potentially improve cancer detection by better visualization and targeting of cancer focus. We evaluated the role of fusion biopsy in detection of prostate cancer and the association of prostate imaging reporting and data system (PI-RADS) score for predicting cancer risk and its aggression...
