BACKGROUND
This study aims to evaluate the application value of Guglielmi detachable coils (GDCs) in the embolization of iatrogenic renal hemorrhage.

METHODS
Twelve iatrogenic renal hemorrhage patients who failed conservative treatment were randomly treated by superselective transcatheter arterial embolization (TAE) with GDCs, gelatin sponge, and microcoil embolization, respectively. The efficacy of treatment, damage to renal function, and renal infarct size were observed.

RESULTS
Embolizations were successful in all patients on the first attempt. Hematuria disappeared completely after the surgery; no recurrence of hemorrhage and no abnormal renal function were observed during the follow-up period. Postoperative angiography revealed that patients treated with GDC embolization had minimum renal infarcts.

CONCLUSIONS
In summary, while superselective TAE provides a safe and effective therapy in patients with iatrogenic renal hemorrhage, the application of GDCs can better prevent the loss of normal renal tissue after embolization.
