Abstract
Page kidney is a condition where external compression of the renal artery and renal parenchyma leads to subsequent ischaemia and activation of renin-angiotensin-aldosterone axis. A 42-year-old female with hirsutism, hypertension and diabetes was diagnosed with a right adrenal mass and underwent laparoscopic adrenalectomy. Her hypertension worsened postoperatively and was managed medically. Subsequently she developed a right flank pain on the fifth postoperative day and died suddenly the next day. Autopsy revealed a pale body with cushingoid appearance. Surgical scars were healthy. Internal examination of the abdomen revealed a haemoperitoneum of 500 ml together with a large subcapsular haematoma measuring 1000 ml surrounding the right kidney, compressing the right renal artery. Kidneys were pale and the right kidney was soft and friable. Cortical surface of the right kidney demonstrated a possible surgical puncture site with an overlying thrombus together with a contused inferior vena cava. Other organs were pale but appeared otherwise normal. Histology revealed diffuse cortical necrosis of right kidney and features of adult respiratory distress syndrome in the lungs. Haemorrhagic shock following laparoscopic adrenalectomy for right adrenal tumor was declared as the cause of death, contributed by the development of the Page kidney. Trauma of several aetiologies including laparoscopic abdominal surgery may contribute to Page kidney. It presents with flank pain, hypertension and renal mass. Since postoperative blood loss usually manifests as hypotension, resulting hypertension may mislead the attending clinicians. Once diagnosed, it can be managed with surgical drainage and antihypertensives.

A Rare Case of Page Kidney in a Young Man with Flank Pain. J Emerg Med 2024; 66:e369-e373. [PMID: 38278675 DOI: 10.1016/j.jemermed.2023.10.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 09/03/2023] [Accepted: 10/01/2023] [Indexed: 01/28/2024]
Abstract
BACKGROUND Page kidney is a rare condition in which an external compression of the kidney as a result of a hematoma or mass causes renal ischemia and hypertension. In a patient with flank pain, elevated blood pressure, and recent trauma, this condition should be considered. Since this condition was first described in 1939, more than 100 case reports have surfaced. CASE REPORT We describe the case of a 26-year-old man who presented to the Emergency Department with flank pain, vomiting, and elevated blood pressure. A computed tomography scan of the abdomen and pelvis confirmed the presence of a perinephric hematoma, and the interventional radiology team was consulted to resolve the Page kidney. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Symptoms seen in Page kidney may be similar to other more common diagnoses encountered in the emergency department. It is important to maintain a high suspicion and order imaging studies as needed, especially in the setting of trauma, or a recent procedure in the vicinity of the renal parenchyma.

Abstract
Page's kidney is a condition that occurs due to external renal compression, usually caused by a subcapsular haematoma, generating a renal compartmental syndrome with parenchymal damage and renal perfusion alteration. Classically associated with renal trauma, Page's kidney can also arise after invasive renal procedures, such as renal biopsies or percutaneous nephrostomies. Clinically, it can trigger hypertension due to activation of the renin-angiotensin system induced by hypoperfusion secondary to renal parenchymal compression and can also present with varying degrees of renal function impairment. Furthermore, severe acute renal failure may be found particularly in patients with solitary kidneys or renal transplants. We present two cases of Page's kidney after renal biopsy and their PoCUS ultrasound findings. We would like to highlight the reversed diastolic flow on Doppler ultrasound in this entity, a pattern we have found in all two cases.

Abstract
Page kidney is caused by the perirenal or subcapsular accumulation of blood or fluid pressing on the renal parenchyma and is a rare cause of secondary hypertension. In this study, we report a case of Page caused by bilateral spontaneous subcapsular renal hematoma, the main manifestations of which were secondary hypertension, multiple serous effusions, and renal insufficiency. After admission, drug blood pressure control was ineffective. After bilateral perirenal effusion puncture and drainage were performed to relieve bilateral perirenal compression, blood pressure gradually dropped to normal, multi-serous cavity effusion (pericardial, thoracic, and abdominal effusion) gradually disappeared, and kidney function returned to normal. Secondary hypertension caused by Page kidney can be treated. When Page kidney is complicated with multiple serous effusions, the effect of antihypertensive drugs alone is poor, and early perineal puncture drainage can achieve better clinical efficacy.

Abstract
Page kidney is a pathologic and rare occurrence caused by a compression of renal parenchyma leading to hypertension. When infiltrated or engulfed by extrinsic matter, the subcapsular region surrounding the renal tissue may cause blanket compression, leading to the activation of the renin-angiotensin-aldosterone system secondary to renal hypoperfusion. While most cases of Page kidney are secondary to blunt trauma to the costovertebral angle, herein we present a case of Page kidney due to renal parenchymal core needle biopsy. The rarity of our case is not due to the cause of such an incidence but because our case resulted in a hypertensive emergency treated with dual intravenous infusions.

Abstract
Page kidney results from external compression of the kidney by a subcapsular hematoma and is one of the rare but treatable causes of secondary hypertension. The majority are traumatic or iatrogenic and often unilateral. Spontaneous bilateral Page kidney is rare. Case Presentation A 35-year P1 with gestational hypertension presented with a persistent postpartum elevation of blood pressure (BP). Imaging studies revealed bilateral renal subcapsular hematoma (left>right). She was managed with an angiotensin receptor blocker initially and ultrasound-guided percutaneous drainage of the collection for the optimal control of elevated BP. Clinical Discussion Ultrasonography and computed tomography of the kidneys are the most frequently used for diagnosing a Page kidney. Medical management with antihypertensive and regular follow-ups form the first line of treatment in Page kidneys. Percutaneous drainage, surgical decortication, laparoscopic intervention, and nephrectomy are necessary in cases of organized late hematomas. Conclusion Spontaneous bilateral Page kidney is a rare but potentially treatable and curable form of hypertension. Percutaneous drainage is an effective method to drain the hematoma and control elevated BP.

Abstract
BACKGROUND Page kidney (PK) is the occurrence of kidney hypoperfusion and ischemia due to pressure on the kidney by a subcapsular hematoma (SH), a mass, or fluid collection. SH after renal transplantation may result in kidney ischemia and graft loss. CASE PRESENTATION We present a rare case of early spontaneous SH in an allograft kidney that led to a decrease in renal function. A 56-year-old male patient underwent deceased donor kidney transplantation. After declamping, appropriate renal perfusion and immediate diuresis were observed, with no evidence of SH. However, his urinary output abruptly decreased 6 h postoperatively. Abdominal ultrasonography showed 28 mm deep SH on transplant and the resistive index (RI) increased to 0.98-1 and diastolic flow reversal was observed. Surgical interventions were performed 2 days after transplantation, following a further decrease in urinary output. Serum creatinine decreased to 2.2 mg/dL, urinary output increased to an average of 200 cc per hour and the RI value was decreased to 0.7 on POD 7. CONCLUSION In patients with abrupt decreased renal function after transplantation, SH should be suspected and the presence of PK should be determined using Doppler USG. In these cases, surgical intervention may avoid allograft dysfunction.

Abstract
INTRODUCTION Page kidney (PK) is a rare condition caused by parenchymal compression due to a subcapsular hematoma. Irreversible damage of the graft may occur if this condition is not recognized and treated properly. CLINICAL CASE We describe the case of a 16-year-old man with chronic renal failure secondary to corticosteroid-resistant nephrotic syndrome (CRNS) caused by NPHS2 mutations. The patient underwent a 5th fifth living-related KT. The graft was placed intraperitoneally and reperfused well without complications. On the 4th postoperative day his labs demonstrated raising creatinine associated with refractory hypertension, gross hematuria and anemia. Urgent ultrasound revealed a subcapsular hematoma with signs of parenchymal compression. PK phenomenon was suspected and urgent surgical intervention decided. COMMENTS PK is a rare but an emergence potentially treatable and reversible complication after pediatric KT. Early diagnosis based on clinical suspicion and suggestive imaging are the key points for a favorable outcome.

Abstract
Renal angiomyolipomas are the most common benign tumors of the kidneys. They are prone to rupture, which may result in massive hemorrhage and often requires lifesaving nephrectomy. Delay in treatment is likely to result in death. We report two cases of ruptured angiomyolipoma compressing the renal parenchyma, causing secondary hypertension (Page kidney). Both patients presented with abdominal pain, hypertension, and reduced or dropping hemoglobin counts. The delay in diagnosis and treatment resulted in their adverse outcomes. We highlight the need to promptly diagnose and treat symptomatic renal hematomas to avoid subsequent morbidity and mortality.

Abstract
INTRODUCTION AND IMPORTANCE Post-surgical Page kidney due to large renal hematoma following percutaneous nephrolithotomy (PCNL) is a rare significant complication that may lead to loss of a kidney. CASE PRESENTATION A 50-year-old lady underwent elective left side PCNL for a 3 cm renal pelvis stone, and one week later, she presented back with a massive renal hematoma with high blood pressure. CLINICAL DISCUSSION The ultrasound abdomen and computed tomography diagnosed a page kidney due to massive intrarenal and perirenal hematoma as a complication of PCNL. Angioembolization and percutaneous aspiration were failed, and the antihypertensives also failed to control the blood pressure. Therefore, she underwent a left-side simple nephrectomy and had an uneventful recovery with reversal of normal blood pressure. CONCLUSION Post-surgical page kidney needs to identify early to facilitate the percutaneous radiological interventions that may preserve the renal parenchyma and avoid further surgeries. Nevertheless, late cases or the failed radiologically intervened cases need open renal exploration and simple nephrectomy, which may be the bailed-out procedure to reverse the consequence of page kidney.

Abstract
The authors present a case of a patient who experienced a rare complication after attempted renal angioplasty and stenting, Page kidney. This patient presented with new onset hypertension secondary to bilateral renal artery stenosis and was referred for revascularization given hypertension refractory to medical management. The right renal artery underwent successful angioplasty and stenting; however, the left renal artery experienced recoil stenosis. Post‐procedure the patient developed acute kidney injury secondary to Page kidney from subcapsular and extracapsular hematoma. This was managed conservatively with transfusions and the hematoma and acute kidney injury self‐resolved over the next 4 months. This case highlights the importance of revascularization for refractory hypertension secondary to hemodynamically significant bilateral renal artery stenosis, the rare complication of Page kidney with attempted revascularization of renal artery stenosis and the involvement of a hypertension specialist in the decision of revascularization of renal artery stenosis.

Abstract
INTRODUCTION AND IMPORTANCE Hypertensive crisis may be a life-threatening condition to any patient and represents an even more serious condition in trauma patients following severe hemorrhage. CASE PRESENTATION We present a case were surgical drape packing induced hypertensive crisis in a trauma patient, recently resuscitated from abdominal hemorrhage. CLINICAL DISCUSSION We argue that direct compression of the kidney by the surgical drapes induced hypersecretion of renin with a mechanism equal to Page kidney. The hypertensive crisis as well as the hyperreninemia was resolved after removing the surgical drapes, and the patient's condition returned to normal without any sequelae. CONCLUSION We encourage considering this unusual but important complication when packing of the abdomen has been carried out, and strongly recommend ruling out renin-mediated hypertension as a cause of post-operative hypertension in such cases.

Abstract
BACKGROUND Patients with flank pain and hematuria are common emergency department presentations of nephrolithiasis. We may anchor on this etiology and potentially miss other less common differentials. We present a case of a patient with hematuria and flank pain typical of nephrolithiasis who was diagnosed with a Page kidney causing secondary hypertension. A 50 year-old male with no significant past medical history presented to the Emergency Department with severe left-sided flank pain, vomiting, and blood-tinged urine. We pursued a diagnosis of nephrolithiasis and found a left renal subcapsular hematoma on non-contrast CT. A CTA was done with no active hemorrhage found. The patient had no history of recent trauma and was found to be hypertensive on evaluation. Urology was consulted and management for the patient's hypertension was initiated. He was diagnosed with Page Kidney and admitted to medicine for observation and hypertension management with an angiotensin-converting enzyme inhibitor. Page Kidney is a diagnosis that describes compression of the renal parenchyma by a hematoma or mass causing secondary hypertension through the activation of the renin-angiotensin-aldosterone system. Causes may include traumatic subcapsular hematoma, renal cyst rupture, tumor, hemorrhage, arteriovenous malformation, among others. Treatment may involve conservative measures including hypertension management, or more invasive measures like evacuation or nephrectomy. We describe the case of a patient presumed to have nephrolithiasis presenting with typical left-sided flank pain, diagnosed with Page kidney, and treated conservatively.

Abstract
The page kidney phenomenon is often associated in patients with abdominal trauma. External compression from a renal hematoma can cause hypertension, and presentation can be delayed following the initial injury. For patients who have a kidney allograft, page kidneys may lead to renal insufficiency and acute renal failure due to the absence of a contralateral kidney to compensate. This case report discusses the identification and management of a page kidney in a kidney allograft recipient within three months following transplantation.

Abstract
We describe a case of unilateral renal lymphangiectasia (RLM) in a 30-year-old male with severe, refractory hypertension (HTN) and end-organ effects despite five anti-hypertensives. After diagnostic testing, the patient ultimately underwent a successful right laparoscopic nephrectomy with significant improvement of HTN. We review the literature regarding the pathophysiology and management strategies of HTN in patients with renal lymphangiectasia. Renal lymphangiectasia (RLM) is an uncommon cause of secondary hypertension. RLM is diagnosed using conventional imaging which notes dilated perinephric and/or peri-pelvic lymphatic channels. RLM is believed to be an uncommon benign and congenital developmental malformation of the renal sinus lymphatics. Clinically the condition is most often asymptomatic, but symptoms may include flank pain, hematuria, ascites, weight loss, HTN, or other vague constitutional symptoms. Antihypertensive therapy is the mainstay of treatment, but refractory drainage and/or nephrectomy may improve BP control.

Abstract
Percutaneous renal biopsy with ultrasound guidance is a helpful procedure regularly performed to obtain renal tissue diagnosis for rejection in the postrenal transplant setting; however, it is not without risks. We report the case of a 42-year-old male with end stage renal disease who developed a subcapsular hematoma, with subsequent hypertension and renal failure, compatible with acute page kidney as a complication of the renal biopsy. The ultrasound images demonstrated classic imaging appearances which all diagnostic and interventional radiologists should be aware of. The patient was managed successfully with conventional open surgical evacuation of the hematoma with return to baseline laboratories and vital signs after the procedure.

Abstract
Background Page kidney phenomenon is caused by strong renal parenchymal compression and leads to renal hypoperfusion and microvascular ischemia, resulting in renal dysfunction and hypertension. Although the development of Page kidney phenomenon in allograft is rare, most of its cases are induced by allograft biopsy or trauma. We observed a case of Page kidney phenomenon that was induced by unusual causes immediately after kidney transplantation. Case presentation A 66-year-old man, whose wife donated a kidney, underwent ABO-compatible living kidney transplantation. The allograft had three renal arteries that were trimmed and formed into one piece on the back table, and subsequently, it was anastomosed to the internal iliac artery. Intraoperative Doppler ultrasonography (US) revealed adequate blood flow of each renal artery. Urine output was also observed as soon as allograft blood flow was reperfused. After the surgery, the urine output decreased, and serum creatinine level increased to 6.0 mg/dL. Doppler US did not show evidence of acute rejection, ureteral obstruction, or anastomotic stenosis of the renal arteries. On postoperative day 7, surgical exploration was performed and revealed that the blood flow of each renal artery was adequate but subcapsular hematoma was detected at the upper pole of the allograft. Capsulotomy and hematoma evacuation were performed. Subsequently, urine output increased and serum creatinine level decreased up to 1.7 mg/dL. Allograft sample was obtained 1 h after the transplantation from the lower pole of the allograft. Although the cause of subcapsular bleeding was unclear in this case, a small cyst of the allograft, which might have ruptured during donor nephrectomy, was located in the middle of the hematoma, and oozing around the cyst was observed. Conclusions Our case indicated that the small ruptured cyst of the allograft could be the cause of subcapsular hematoma and Page kidney phenomenon. Subcapsular hematoma caused by oozing over time could be difficult to diagnose using Doppler US, and thus, other imaging modalities, such as computed tomography, should be considered. Knowledge of the Page kidney phenomenon in the allograft can lead to early diagnosis and intervention, resulting in better outcomes for recipients with allograft dysfunction.

Abstract
99mTc diethylenetriaminepentaacetic acid (DTPA) renogram is a commonly performed evaluation postrenal transplant to assess graft function and for early detection of suspected immediate and late transplant-associated complications. Although several modalities can be utilized to detect perinephric collection in posttransplant period, the utility of 99mTc DTPA single-photon emission-computed tomography (SPECT-CT) is not recognized. Herein, we discuss the incremental role of seldom considered SPECT-CT in early detection, leading to timely appropriate management and graft salvage in a case of posttransplant deteriorating renal allograft as a result of subcapsular hematoma.

Bilateral nontraumatic recurrent Page kidney. Radiol Case Rep 2017; 12:511-513. [PMID: 28828114 PMCID: PMC5552010 DOI: 10.1016/j.radcr.2017.05.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2017] [Revised: 04/11/2017] [Accepted: 05/19/2017] [Indexed: 11/19/2022] Open
Abstract
Page kidney is a rarely seen phenomenon leading to secondary hypertension and encountered most frequently due to traumatic or nontraumatic subcapsular hematoma. Such a compression in kidneys causes hypoperfusion and microangiopathic ischemia and activates renin-angiotensin-aldosterone system leading to hypertension. In this presentation, we report a rare case of bilateral Page kidney presenting with hypertension attacks due to spontaneous subcapsular hematoma developing in different kidneys at different times.

Allograft loss from acute Page kidney secondary to trauma after kidney transplantation. World J Transplant 2017; 7:88-93. [PMID: 28280700 PMCID: PMC5324033 DOI: 10.5500/wjt.v7.i1.88] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2016] [Revised: 12/19/2016] [Accepted: 01/14/2017] [Indexed: 02/05/2023] Open
Abstract
We report a rare case of allograft loss from acute Page kidney secondary to trauma that occurred 12 years after kidney transplantation. A 67-year-old Caucasian male with a past surgical history of kidney transplant presented to the emergency department at a local hospital with left lower abdominal tenderness. He recalled that his cat, which weighs 15 lbs, jumped on his abdomen 7 d prior. On physical examination, a small tender mass was noticed at the incisional site of the kidney transplant. He was producing a normal amount of urine without hematuria. His serum creatinine level was slightly elevated from his baseline. Computer tomography revealed a large subscapular hematoma around the transplant kidney. The patient was observed to have renal trauma grade II at the hospital over a period of three days, and he was finally transferred to a transplant center after his urine output significantly decreased. Doppler ultrasound demonstrated an extensive peri-allograft hypoechoic area and abnormal waveforms with absent arterial diastolic flow and a patent renal vein. Despite surgical decompression, the allograft failed to respond appropriately due to the delay in surgical intervention. This is the third reported case of allograft loss from acute Page kidney following kidney transplantation. This case reinforces that kidney care differs if the kidney is solitary or a transplant. Early recognition and aggressive treatments are mandatory, especially in a case with Doppler signs that are suggestive of compression.

Laparoscopic treatment of Page kidney: a report of two cases and review of the literature. Turk J Urol 2015; 39:126-30. [PMID: 26328095 DOI: 10.5152/tud.2013.024] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2012] [Accepted: 08/28/2012] [Indexed: 12/28/2022]
Abstract
Page kidney is defined as the external compression of the kidney, typically by a subcapsular hematoma, that leads to hypertension due to hypoperfusion and ischemia. The treatment options include medical anti-hypertensive treatment, percutaneous drainage, surgical decortication and nephrectomy. Laparoscopic decortication of Page kidney is a newly defined minimally invasive management technique. We describe 2 cases of Page kidney that failed to improve with percutaneous drainage but were successfully treated with the laparoscopic approach.
