Transperineal vs Transrectal Prostate Biopsy: Route, Infection Risk and Detection
Transperineal route Transrectal route Transperineal and transrectal prostate biopsy differ mainly in the route the biopsy needle takes to reach the prostate—not in the underlying purpose of the biopsy. A transperineal biopsy passes the needle through disinfected perineal skin, while a transrectal biopsy passes the needle through the rectal wall. Both routes can sample MRI […]
What Is an MRI-Targeted Prostate Biopsy? Lesion Targeting and Systematic Sampling
An MRI-targeted prostate biopsy is a biopsy in which tissue cores are deliberately directed into a suspicious prostate lesion that was identified on MRI. Instead of sampling the gland only according to a fixed anatomical template, the radiologist’s MRI location is transferred to the biopsy procedure so the needle can pass through the abnormal tissue […]
Prostate Biopsy Recovery: Blood, Infection Risk, Urinary Symptoms and Healing
Post-biopsy observation Recovery guide Most men recover from a prostate biopsy over several days, although blood in the semen can remain visible for several weeks. Mild soreness, small amounts of blood in the urine, and—in a transrectal biopsy—minor rectal bleeding can occur after tissue cores are taken. A transperineal biopsy may instead leave temporary perineal […]
Prostate Ultrasound (TRUS): Imaging, Prostate Volume and Biopsy Guidance
TRUS Real-time ultrasound Prostate volume Biopsy guidance Transrectal ultrasound (TRUS) is a prostate imaging procedure in which a small ultrasound probe is placed in the rectum so sound waves can create real-time images of the prostate immediately in front of it. TRUS is especially useful for measuring prostate dimensions and volume, visualizing prostate anatomy during […]
What Is the Gleason Score? Prostate Cancer Pattern, Grade and Risk
The Gleason score is a microscopic grading system for prostate adenocarcinoma that describes how abnormal and disorganized the cancer’s glandular architecture looks compared with normal prostate tissue. A pathologist identifies the dominant cancer growth patterns in biopsy or prostate-removal tissue, assigns Gleason pattern grades, and combines two patterns into a score. In contemporary practice, prostate […]
Gleason Score vs Grade Group: How Prostate Cancer Grading Systems Relate
Gleason score • 3+4=7 ISUP Grade Group • 2 Gleason score and ISUP Grade Group describe the same underlying prostate-cancer histology in two different formats. The Gleason system preserves the actual microscopic pattern combination—such as 3+3, 3+4 or 4+3—while the Grade Group system translates those combinations into a simpler scale from 1 to 5. They […]
Prostate Cancer Stages: Localized, Locally Advanced and Metastatic Disease
Primary tumor • T Regional nodes • N Distant spread • M Overall stage • I–IV Prostate cancer stage describes how far the cancer has spread anatomically—from disease confined to the prostate, through extension into nearby tissues or regional lymph nodes, to cancer that has metastasized to distant parts of the body. The core anatomical […]
Localized Prostate Cancer: Risk Groups, Active Surveillance and Curative Treatment
Anatomy • T1–T2 Nodes • N0 Distant spread • M0 Risk • not uniform Localized prostate cancer means the cancer is confined to the prostate with no identified regional lymph-node or distant metastatic spread. In TNM terms, localized disease is generally T1–T2, N0, M0. That anatomical definition does not mean every localized cancer requires treatment […]
Advanced Prostate Cancer: Locally Advanced, Recurrent and Metastatic Disease
Local extension Recurrence Distant spread Treatment response Advanced prostate cancer is an umbrella clinical term for prostate cancer that has moved beyond a straightforward localized disease state. Depending on context, it may refer to cancer that has grown beyond the prostate into nearby tissues, reached regional pelvic lymph nodes, returned after earlier curative treatment, or […]
Metastatic Prostate Cancer: How It Spreads, Common Sites and Treatment
M1a • distant nodes M1b • bone M1c • other sites Systemic disease Metastatic prostate cancer means prostate cancer cells have spread from the prostate to a distant site in the body. In TNM staging this is M1 disease. The most common clinically important patterns involve distant lymph nodes and bone, while some patients develop […]
