Retroperitoneal hematoma post percutaneous sacral nerve evaluation: A case report

Sacral neuromodulation is an accepted therapy for various voiding dysfunction. We report a 71-year-old male with a history of BPH post TURP and overactive bladder. He was on anticoagulants for atrial fibrillation. He underwent uneventful percutaneous sacral nerve evaluation. Five days later, he showed no improvement. Temporary lead was removed in clinic without complications. On day ten, he developed lower abdominal, and genital skin bruising. CT scan showed presacral retroperitoneal hematoma. His Hemoglobin dropped. He was admitted, managed conservatively and discharged with a stable hemoglobin. Retroperitoneal hematoma post PNE is rare. Management is conservative. Angioembolization is reserved for unstable patients.
