A percutaneous renal biopsy is an essential tool for the diagnosis of various renal diseases; however, post-biopsy
bleeding is a major complication.
Hemocoagulase is a detoxified and purified
snake venom enzyme that is widely used to prevent post-procedural
bleeding. In this study, we retrospectively analyzed the effect of
hemocoagulase on post-renal biopsy
bleeding. We included 221 patients who underwent percutaneous renal biopsy between April 2017 and December 2020 and analyzed post-renal biopsy
hemoglobin (Hb) decline in patients who were administered a periprocedural
hemocoagulase injection. After the renal biopsy, the mean Hb decrease in the entire patient cohort was 0.33 ± 0.84 g/dL. Periprocedural
hemocoagulase injection lowered the Hb decline post-renal biopsy (0.50 ± 0.87 vs. 0.23 ± 0.80 g/dL, p = 0.0204). The propensity-matched cohort was also adjusted for factors influencing postprocedural
bleeding; periprocedural
hemocoagulase injection reduced the Hb decline post-renal biopsy (0.56 ± 0.89 vs. 0.17 ± 0.74 g/dL, p = 0.006). There were no adverse events (e.g.,
thrombosis and
anaphylactic shock) due to
hemocoagulase. Our study demonstrated the beneficial effect of
hemocoagulase on post-renal biopsy Hb decline, suggesting its clinical value in preventing post-renal biopsy
bleeding.
