Subcapsular renal hematoma (ScRH), albeit not a common entity in clinical practice, is a life-threatening condition when it is stopped naturally by the tamponade effect of the renal capsule. Renal tumors, renal vascular diseases, trauma and iatrogenic reasons are held responsible in the etiology. The affected patients present to emergency departments with the symptoms and sings comprising sudden onset flank pain, abdominal tenderness and hematuria. We presented in this paper three case reports related to ScRHs; the first with spontaneous ScRH; the second with the ScRH induced by anticoagulation therapy; and, the third with traumatic ScRH. We implemented conservative treatment in all of the patients. Moreover, we aimed, along with the current literature, to commence a discussion on the etiological reasons, the clinical presentation and the treatment approaches with regard to ScRH.
