Abstract
PURPOSE: To assess clinical presentation and outcomes of different treatment strategies in cases of spontaneous renal hemorrhage (SRH). METHODS: A retrospective analysis of patients with SRH between 2000 and 2018 was performed. Patients' demographics, clinical presentation, laboratory and radiological investigations, and different lines of treatment were retrieved. The primary outcome was to assess the predictors of the success of conservative treatment. The secondary outcome was to assess the long-term renal function outcome comparing serum creatinine, e GFF, and CT-assessed renal volume at last follow-up with baseline values. RESULTS: The study included 42 (23 males and 19 women) patients with mean ± SD age was 48.1 ± 17.8 years. Conservative management was successful in 19 (46%) patients. Trans-arterial embolization (TAE) was performed in 13 patients (30%) to control active bleeding. Ten patients (25%) required surgical exploration and nephrectomy. Lower serum creatinine (P = 0.003), higher prothrombin concentration (P = 0.04), lower hematoma size (P = 0.02), and non-AML lesions (P = 0.03) were independent predictors of conservative management success. Unlike the TAE-treated group, serum creatinine increased significantly (P = 0.04) with a significant decrease in e-GFR (P = 0.02) and renal volume (P < 0.001) of affected kidneys at last follow-up after conservative treatment. CONCLUSION: Although SRH is a life-threatening condition, conservative treatment is successful in a certain subset of patients. However, it is associated with significant deterioration of the affected kidney function as well as renal volume.
