Summary
Suprapubic ultrasonography provides essential prostate information for daily use. However, transrectal ultrasound is better for assessing echo structure in prostate cancer, though not always needed for diagnosis.
Area of Science:
- Urology
- Medical Imaging
Background:
- Suprapubic ultrasonography is a non-invasive method for evaluating prostate size, shape, and residual urine volume.
- Transrectal ultrasonography offers superior detail for assessing prostate echo structure, particularly in cases of suspected or confirmed prostate cancer.
Purpose of the Study:
- To compare the utility of suprapubic and transrectal ultrasonography in prostate evaluation.
- To determine the role of transrectal ultrasound in the diagnosis and screening of prostate cancer.
Main Methods:
- Review of clinical data and imaging findings from suprapubic and transrectal ultrasound examinations.
- Correlation of imaging findings with clinical examination, prostate-specific antigen (PSA) levels, and biopsy results.
Main Results:
- Suprapubic sonography is suitable for routine clinical assessment of prostate size, form, and residual urine.
- Transrectal sonography is more effective for evaluating echo structure, especially in prostate cancer.
- Transrectal ultrasound is often unnecessary for diagnosing prostate cancer when rectal palpation, PSA, and biopsy are conclusive.
- Transrectal sonography demonstrates poor sensitivity and specificity for early prostate cancer screening.
Conclusions:
- Suprapubic ultrasonography is a valuable tool for routine prostate assessment.
- Transrectal ultrasound is indicated for detailed evaluation of prostate cancer but not recommended for early screening due to limitations in sensitivity and specificity.
