Painless Hematuria on Apixaban: Whose Call Is It?
Mr. D., 62, is seen in clinic for two episodes of painless gross hematuria over 10 days. He takes apixaban 5 mg twice daily for atrial fibrillation and lisinopril. He is hemodynamically stable: BP 134/80, HR 78, temperature 36.7°C, respirations 16. Hemoglobin is 10.9 g/dL (baseline 13.8), platelets 210,000, INR 1.1. He has no dysuria, fever, flank pain, or clot retention, and he voids without difficulty. He asks, "Can't I just stop the apixaban for a week and see if the bleeding stops?" He has a colonoscopy scheduled next month and assumes the blood is from hemorrhoids. His father had bladder cancer at age 70. The clinic is busy and the next urology appointment is in 6 weeks.
1. What is the priority concern, and why is watchful waiting inappropriate?
Read the worked answer
Painless gross hematuria in a 62-year-old is a red flag for urothelial malignancy until proven otherwise, even with anticoagulation. Apixaban can worsen bleeding but does not explain why bleeding started; anticoagulated patients still require the same evaluation. His hemoglobin has fallen from 13.8 to 10.9 g/dL, which indicates more than trivial bleeding. Family history of bladder cancer at age 70 adds risk. Watchful waiting for 6 weeks is inappropriate because bladder cancer can progress and because clot retention or anemia may develop. The priority is urgent urology referral for cystoscopy and upper-tract imaging, typically CT urography, plus urinalysis and urine cytology as ordered. I would not advise stopping apixaban; that decision belongs to the prescriber and cardiology, balancing stroke risk. I would contact urology directly to request an earlier slot rather than waiting for the routine appointment.
2. What will you teach and what will you arrange before he leaves?

Teach him to continue apixaban unless the prescriber specifically changes it, and to report black stools, worsening blood, dizziness, palpitations, or inability to void. Explain that a bladder camera examination is needed and that hemorrhoids do not explain blood coming from the urinary tract. Instruct him to maintain hydration and to seek emergency care for clot retention, severe suprapubic pain, or lightheadedness. Arrange an urgent urology referral, baseline CBC and renal function, and a plan for cystoscopy; document the conversation, his understanding, and the referral. Reassure him that the evaluation is routine but time-sensitive. If he declines, document informed refusal and the risks.
