Differential Diagnosis
- Single most likely diagnosis
- Hemorrhagic cystitis: The presence of a 7 cm blood clot and dependent blood products in the urinary bladder, along with a history of blood in the urine, makes hemorrhagic cystitis the most likely diagnosis. This condition is characterized by bleeding from the bladder mucosa and can be caused by various factors such as infection, radiation, or chemical exposure.
- Other Likely diagnoses
- Bladder diverticulum rupture: The large right posterolateral bladder wall diverticulum could potentially rupture, leading to bleeding and blood clots in the bladder.
- Urinary tract infection (UTI): The presence of blood in the urine and a distended urinary bladder could be indicative of a UTI, which could be causing the bleeding.
- Bladder cancer: Although less likely, bladder cancer could be a possible cause of the bleeding and blood clots in the bladder.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Sepsis: If the bleeding is caused by an infection, there is a risk of sepsis, which is a life-threatening condition that requires prompt treatment.
- Urethral obstruction: A blockage in the urethra could be causing the distended bladder and bleeding, and if left untreated, could lead to serious complications.
- Trauma: Although not mentioned in the history, trauma to the bladder or urethra could be a possible cause of the bleeding and should not be missed.
- Rare diagnoses
- Arteriovenous malformation (AVM): A rare condition where there is an abnormal connection between arteries and veins, which could be causing the bleeding in the bladder.
- Vasculitis: Inflammation of the blood vessels could be causing the bleeding in the bladder, although this is a rare condition.
- Bleeding disorder: A rare bleeding disorder, such as hemophilia, could be causing the bleeding in the bladder, although this would likely be known in the patient's history.
