Aim: It has been recognized that renal lesions in patients with diabetes often have other causes of renal damage concomitantly. Renal biopsy is a valuable tool to provide histological evidence. However, the safety in patients with type 2 diabetes receiving renal biopsy is not well evaluated. This study was conducted to monitor the dynamic complications and to evaluate the safety of biopsy in diabetic patients.
Methods: A prospective observation was performed on 130 patients with type 2 diabetes and 150 patients not undergoing renal biopsy. The complications were monitored at 4 h, 8 h, 24 h, 48 h and 72 h sequentially after biopsy.
Results: Haematoma was observed in 34 (26.15%) patients with diabetes and 50 (33.33%) in controls (P = 0.19). The timing of large haematoma peaked at 4 h. Gross haematuria occurred in 12 (9.23%) diabetic patients and eight (5.33%) controls (P = 0.207). It happened mainly within 8 h. Renal pathological diagnosis showed 96 (73.85%) cases with diabetic nephropathy and 34 (26.15%) cases with non-diabetic renal disease.
Conclusion: Renal biopsy in patients with type 2 diabetes is safe. The frequency of complications after renal biopsy in diabetes is no higher than those without diabetes. The complications mostly happened within 8 h, especially within 4 h. Biopsy is also very necessary to rule out other chronic renal diseases in diabetes.
