Abstract

Objectives This study aims to illustrate indications, contraindications, techniques, and complications of ultrasound-guided renal biopsy and its role in the diagnosis of various renal disorders. Background Percutaneous ultrasound-guided renal biopsy is the gold standard in the evaluation of renal diseases. Recent advances in technique have improved the safety of the procedure. Material and methods This prospective study was conducted between October 2010 and October 2012 on 30 consecutive patients with various indications for ultrasound-guided renal biopsy. Results There were 24 patients with diffuse renal pathology and six patients with focal renal pathology; 15 patients used free-handed biopsy and 15 patients used automated gun biopsy, and complications of the renal biopsy was observed in 10 patients with hematuria (33.3%), whereas 20 patients showed no complications (66.7%). Conclusion Our results support that the use of automated gun loaded with Tru-cut needles under ultrasound guidance is a safe and an efficient method for performing renal biopsies in patients. The use of smaller (18 G) needles would reduce the complication rate while allowing the retrieval of sufficient tissue for histological diagnosis.
