|March 1, 1978
Summary
Ultrasound-guided percutaneous renal biopsies are safe and effective, yielding adequate tissue in 96.1% of cases. This method offers advantages over alternative techniques for obtaining kidney tissue samples.
Area of Science:
- Nephrology
- Medical Imaging
- Surgical Procedures
Background:
- Percutaneous renal biopsy is a critical diagnostic procedure.
- Minimally invasive techniques are preferred for renal biopsies.
- Ultrasound guidance offers real-time visualization during biopsies.
Purpose of the Study:
- To evaluate the safety and efficacy of B-mode ultrasound-guided percutaneous renal biopsies.
- To determine the rate of successful tissue acquisition.
- To assess the incidence of major complications.
Main Methods:
- Seventy-six percutaneous renal biopsies were performed.
- B-mode ultrasound was utilized for guidance throughout the procedures.
- Tissue adequacy for diagnosis was assessed post-procedure.
Main Results:
- Successful tissue acquisition was achieved in 73 out of 76 subjects (96.1%).
- Adequate tissue for interpretation was obtained in 72 instances.
- Major bleeding complications occurred in 4 patients (5.3%).
Conclusions:
- B-mode ultrasound guidance is a safe and effective method for percutaneous renal biopsies.
- Ultrasound guidance offers significant advantages compared to other biopsy techniques.
- This technique ensures high rates of diagnostic tissue yield with acceptable complication rates.
