The case of a 77-year-old man, residing in a long-term care facility since September 2019 due to declining autonomy, highlights a diagnostic puzzle involving what appeared to be a worm in his urine. The man, originally from Congo and a resident of France since 2017, suffered a stroke in 2017, resulting in right-side paralysis. He also has complications related to hepatitis C and hepatic cirrhosis. Largely confined to bed or a chair, he requires assistance with all daily activities.
The patient’s medical history includes a left kidney infection (pyelonephritis) in 2019,exacerbated by kidney stones. A 2022 intervention offered limited improvement, leading to recurrent urinary tract infections.Ultimately, a suprapubic catheter – a drainage tube inserted into the bladder – was placed to facilitate urine evacuation.
In October 2024, a nurse observed a long, dark, mobile filament resembling a worm in the urine collection bag. The patient exhibited no fever, abdominal pain, or digestive issues. Blood tests revealed no inflammatory syndrome, and eosinophil levels, typically elevated in parasitic infections, were normal.

Worm or Worry? When a Urinary ‘Worm’ isn’t What It Seems
What does it mean when something looks like a “worm” is in urine?
The appearance of a worm-like structure in urine can be alarming, and a cause for concern for the patient. However, it isn’t always indicative of a parasitic infection. In the case presented, the “worm” was a filamentous structure found in the urine collection bag of a 77-year-old man.
What was observed in the patient’s urine sample?
A nurse observed a long, dark, mobile filament resembling a worm in the urine collection bag. This was found in a patient wiht a complex medical history involving a stroke, hepatitis C, and kidney issues. The patient also had a suprapubic catheter.
Could this really be a worm? What other possibilities exist?
While it’s natural to jump to conclusions, it’s critically important to assess the full context.In this case it *wasn’t* an actual worm. A number of factors can mimic the appearance of a worm:
- Blood clots: Clots can sometimes appear elongated.
- Mucus strands: Mucus can also form long, stringy structures.
- Other materials: Fragments of the urine catheter or other debris can potentially be mistaken for parasitic worms.
What was the patient’s medical history?
The patient had a complex medical history, including:
- A stroke in 2017, resulting in right-side paralysis.
- Complications related to hepatitis C and hepatic cirrhosis.
- A left kidney infection (pyelonephritis) in 2019, exacerbated by kidney stones.
- recurrent urinary tract infections.
- The placement of a suprapubic catheter to help with urine drainage.
Were there any signs of a parasitic infection based on the patient’s symptoms and tests?
No, there were no signs of a parasitic infection, as:
- The patient showed no fever, abdominal pain, or digestive issues.
- Blood tests revealed no inflammatory syndrome.
- Eosinophil levels, usually elevated in parasitic infections, were normal.
What is a suprapubic catheter, and why was it used in this case?
A suprapubic catheter is a drainage tube surgically inserted into the bladder through the lower abdomen. In this instance, it was placed to help with urine evacuation due to the patient’s recurrent urinary tract infections and other medical complications. The patient was largely confined to a bed or chair and required assistance with all daily activities,exacerbating the need for the catheter.
What are some key differences between a real worm infection in the urinary tract and other possibilities?
The following table outlines some distinguishing factors:
| Characteristic | Potential Parasitic Infection | Non-Parasitic Causes (e.g., in this case) |
|---|---|---|
| Symptoms | Could include fever, abdominal pain, dysuria (painful urination), and perhaps eosinophilia (elevated eosinophil count). | Often none related to infection (as in this case), or symptoms tied to the underlying medical conditions, and catheter use. |
| Blood Tests | may show signs of inflammation and, in some cases, elevated eosinophil levels. | Typically, no signs of active inflammation or specific parasitic markers. |
| Urine Analysis | May reveal parasitic eggs or larvae. | May reveal blood clots, mucus, fragments of the catheter, or debris. |
| Treatment | Antiparasitic medications. | Addressing underlying conditions, potentially supportive care, and possibly removal or replacement of the catheter source. |
Why is it critically important to determine the cause of the filamentous structure?
Accurately identifying the cause protects the patient from needless medications.It ensures the appropriate follow-up and, if needed, the right treatment. Misinterpreting the nature of the “worm” could lead to improper care or the delay of a correct diagnosis of existing health conditions. Without a full medical assessment, the “worm” might be the main perceived issue, ignoring potential serious health conditions that need rapid treatment, such as hepatitis C and cirrhosis.
