Overview of Percutaneous Renal Biopsy in Adults: Single-Centre Experience in Private Hospital

Background: Percutaneous renal biopsy is an integral part of the clinical practice of nephrology. Percutaneous renal biopsy is an essential tool in diagnosing and managing kidney disease. This study's objective was to present our center's renal biopsy experience. Methods: A retrospective single-center review study to review all percutaneous renal biopsies done at Mayapada Hospital Lebak Bulus between May 2023 and September 2024. The biopsy was done using continuous ultrasound guidance and a 16-gauge automatic biopsy needle. All biopsies were processed for light and immunofluorescence. Results: 16 patients were aged 18 to above 64; 56% were male. Hematuria with proteinuria was the most common biopsy indication. The number of glomerulus found from histopathological examination was equal, with eight patients with glomerulus finding higher than ten glomerulus. Complications of kidney biopsy, such as hematoma, occurred in 3 patients. The most common clinical manifestation was nephrotic syndrome. At the time of biopsy, six patients with eGFR >90. From histopathological diagnosis, the most common diagnosis was Focal Segmental Glomerulosclerosis (FSGS). Conclusions: Percutaneous renal biopsy using real-time ultrasound with a 16-gauge needle remains a successful and safe procedure. Keywords: percutaneous renal biopsy, ultrasound, diagnosis
