Urologic Radiology
|January 1, 1986
Summary
Percutaneous renal needle biopsies are effective, with 89% diagnostic accuracy on initial attempts. A second biopsy increases accuracy to 98%, demonstrating the value of renal biopsy procedures for patient diagnosis.
Area of Science:
- Nephrology
- Radiology
- Pathology
Background:
- Percutaneous renal needle biopsy is a crucial diagnostic tool.
- Evaluating the diagnostic yield and complication rates is essential for optimizing patient care.
Purpose of the Study:
- To assess the diagnostic adequacy and complication rate of percutaneous renal needle biopsies.
- To analyze biopsy indications and techniques used.
Main Methods:
- Fifty-one percutaneous renal needle biopsies were performed on 46 patients.
- Computed tomographic (CT) guidance was used in 94% of cases.
- Biopsies utilized varying needle gauges (18-21-gauge for masses, 18-gauge cutting or 14-gauge Trucut for medical indications).
Main Results:
- Initial biopsy provided adequate diagnosis in 89% of patients.
- A second biopsy increased diagnostic adequacy to 98%.
- Serious complications occurred in 6% of biopsies.
Conclusions:
- Percutaneous renal needle biopsy is a safe and effective procedure for diagnosing renal masses and medical renal diseases.
- High diagnostic accuracy can be achieved, with a low rate of serious complications.
