Case Presentation: We present four cases of renal hematomas that occurred in our department during the past decade (2008-2018). Unstable vital signs, increased inflammatory markers, fever, and flank pain were the commonest postoperative findings. Two patients were treated conservatively and had an uneventful recovery, whereas one patient underwent selective arterial embolization for bleeding control. The fourth patient was diagnosed with contralateral ureteral urothelial tumor and ultimately underwent contralateral radical nephroureterectomy. Conclusion: Application of safety measures during ureteroscopy may reduce the incidence of perirenal hematomas. Prompt diagnosis is based on a thorough clinical examination in combination with imaging to evaluate the location and extent of the hematoma. © Copyright 2020, Mary Ann Liebert, Inc., publishers. ER -
