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.

Introduccion: El riñón de Page (RP) es una enfermedad rara provocada por compresión parenquimatosa debido a un hematoma subcapsular. El injerto puede sufrir daños irreversibles si la enfermedad no se reconoce y se trata de forma adecuada.

Caso clinico: Describimos el caso de un varón de 16 años con fallo renal crónico secundario a síndrome nefrótico corticorresistente (SNCR) provocado por mutaciones del gen NPHS2. El paciente se somete a un quinto TR de donante vivo. El injerto se coloca en posición intraperitoneal, con una adecuada reperfusión, sin complicaciones. Al cuarto día postoperatorio, sus análisis revelan una subida de la creatinina asociada a hipertensión refractaria, hematuria macroscópica y anemia. La ecografía de urgencia revela hematoma subcapsular con signos de compresión parenquimatosa. Se sospecha RP y se decide intervención quirúrgica de urgencia.

Comentarios: El RP es una complicación rara y urgente, aunque a su vez tratable y reversible, tras TR pediátrico. El diagnóstico precoz basado en la sospecha clínica y las imágenes son claves a la hora de conseguir un resultado favorable.
