Background: Despite being considered minimally invasive, percutaneous nephro-urological interventions; percutaneous nephrolithotomy (PCNL), percutaneous nephrostomy (PCN), and renal biopsy can be associated with massive life-threatening hemorrhage. Surgical management in the form of partial and total nephrectomy is usually associated with marked comorbidity and massive renal parenchymal loss. This study aims to assess the technique and short-term hemostasis of transarterial renal artery embolization in iatrogenic vascular injuries. Methods: In the period between January 2015 and November 2017, 122 patients with suspected renal vascular trauma (100 post-PCNL, 19 postrenal biopsy, and 3 post-PCN) either presenting with hematuria (103 patients) or increasing perinephric hematoma by ultrasonography (19 patients) were referred to our institute for the possibility of embolization. Embolization was done with vascular coils, gelatine sponge particles, N butyl cyanoacrylate, or combination of those agents. Results: The bleeding artery could be identified and embolized in 115 patients; in patients with negative angiography, no further intervention was done. One hundred and nine patients showed clinical improvement in the form of stoppage of hematuria or stabilized vital data and stabilized size of hematoma. Rebleeding occurred in three patients (all embolized by gelatin sponge particles alone) who were treated by another session of embolization. None of the treated patients needed any further surgical treatment. No major complications occurred. Conclusion: In this limited series, transarterial renal artery embolization has shown to be an effective option in the management of iatrogenic renal vascular injuries with high hemostasis as well as low complication rates.
