Summary
Ultrasound-guided percutaneous renal biopsy using an automated system is safe and effective. Radiologists accurately predict sample adequacy, and a pathology technologist ensures sufficient tissue for diagnosis.
Area of Science:
- Nephrology
- Radiology
- Pathology
Background:
- Percutaneous renal biopsy is crucial for diagnosing kidney diseases.
- Automated core biopsy systems and ultrasound guidance offer potential improvements in safety and efficiency.
Purpose of the Study:
- To evaluate the safety and efficacy of ultrasound-guided percutaneous renal biopsy with an automated core biopsy system.
- To assess the accuracy of radiologists in predicting specimen adequacy.
Main Methods:
- Ninety-five percutaneous renal biopsies were performed using a 16-gauge automated core biopsy device under real-time ultrasound guidance.
- Radiologists estimated sample adequacy, with final determination by a pathology technologist. Complications were monitored via ultrasound and patient questionnaires.
Main Results:
- Adequate tissue for diagnosis was obtained in 98.9% of cases.
- Radiologists' adequacy estimates agreed with technologists in 88.4% of cases.
- Complications occurred in 27.4% of biopsies (3.2% major).
Conclusions:
- Ultrasound-guided automated core biopsy is a safe and accurate method for percutaneous renal biopsy.
- Routine post-biopsy ultrasounds for complications are not necessary.
- Pathology technologist presence ensures high rates of adequate tissue samples.

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...
