Introduction
Page kidney is a rare cause of secondary hypertension due to external compression of renal parenchyma, commonly due to subcapsular blood collection after trauma or a procedure. We present 2 cases and their outcomes of Page kidney post renal biopsy, one managed conservatively while the other underwent percutaneous drainage
Case Description
A 60-year-old male with atrophic left kidney underwent a biopsy for a clinical trial. On day 4 post biopsy he was found to have worsening hypertension with AKI. Imaging showed a subcapsular hematoma with parenchymal compression. Serum creatinine (SrCr) had increased up to 8.07 mg/dL (baseline of 2.15 mg/dL). CT guided percutaneous drainage was performed at day 8 with about 250 cc of blood. SrCr and blood pressure improved to baseline afterwards
A 41-year-old female with SLE and lupus nephritis class III/IV underwent a kidney biopsy for worsening SrCr. 10 days post biopsy she developed left upper quadrant and flank pain. Found to have severe anemia with hemoglobin 4.9 g/dL and a SrCr of 3.7 mg/dL (baseline 2.5 mg/dL). Imaging showed a left renal hematoma measuring 8.3 cm with mass effect on the kidney and active contrast extravasation. Due to concern of bleeding drainage of the hematoma was deferred. She underwent embolization and coil deployment of the left inferior renal artery. Scans in clinic showed improved but persistent hematoma. SrCr returned to baseline; however, blood pressure remained elevated months after discharge requiring adjustment of home regimen
Discussion
Page kidney is a known complication of kidney biopsy that causes secondary hypertension. Our first case managed with CT guided percutaneous drainage showed complete resolution of the hematoma and AKI. Our second case showed a slow recovery of the AKI with secondary hypertension requiring dose adjustment of RASi. Percutaneous drainage can be an effective and low risk procedure to consider in acute or subacute cases with better long term clinical efficacy
