How to Deal With Hemophilia C in Endoscopic Urologic Surgery: Lessons Learned From a Transurethral Resection of Bladder Tumor Case.

Factor XI deficiency (hemophilia C or Rosenthal syndrome) is an inherited rare disorder that leads to abnormal bleeding due to the paucity of the protein named factor XI, which plays a role in the blood clotting cascade. A 42-year-old male was referred to the urology outpatient clinic with macroscopic hematuria. The patient was scheduled for a repeat transurethral resection of a bladder tumor (TURBT). Preoperative coagulation parameters were as follows: the international normalized ratio (INR) was 0.95 (0.85-1.2), the prothrombin time was 10.9 seconds (10-15), and the partial thromboplastin time was 43.7 seconds (21-36). On the second postoperative day, he developed pelvic pain and discomfort. An abdominal CT revealed a 10 cm mass consistent with clot retention. The patient received two units of erythrocyte suspension and six units of fresh frozen plasma to prevent the depletion of hemoglobin and control urinary bleeding. The patient was discharged with a good recovery from the hospital three days after the second surgery. Hematologic disorders are rare but might have fatal consequences following surgery if unnoticed at the earliest stage. Clinicians must consider that patients with a history of unusual bleeding or borderline coagulation parameters might have an underlying hematological disorder and perform a further evaluation.
