A 77-year-old man recently experienced a rare and serious complication following a shingles diagnosis: a ruptured bladder. The incident, detailed in a case report, highlights the potential for urinary retention – difficulty emptying the bladder – as a consequence of the viral infection, and underscores the importance of recognizing this potential issue, particularly in individuals with pre-existing conditions.
Shingles, or herpes zoster, is a reactivation of the varicella-zoster virus (VZV), the same virus that causes chickenpox. After a chickenpox infection, the virus remains dormant in the body and can reactivate later in life as shingles, typically presenting as a painful rash with fluid-filled blisters. While most cases resolve with antiviral medication and pain management, complications can occur. This case demonstrates a previously unreported link between shingles-related urinary retention and bladder rupture.
The patient had been diagnosed with shingles a week prior to presenting at the emergency room with urinary retention, experiencing difficulty urinating for four days. He had been taking antiviral and pain medications to manage his shingles symptoms. Upon examination, doctors found his lower abdomen distended and painful, and his heart rate, blood pressure, and respiratory rate were elevated. A CT scan revealed a significant amount of fluid in his abdomen and pelvis, suggesting a possible bladder rupture.
The man was immediately transferred to intensive care, where a urinary catheter was inserted to drain his bladder. Over three hours, the catheter drained blood-tinged urine, revealing a two-centimeter tear in the bladder wall. Emergency surgery was performed to repair the rupture. After several weeks of hospitalization and continued antiviral treatment, the patient was discharged and reportedly regained normal bladder function, according to the medical team who treated him. The case was documented in the journal Infection and Drug Resistance.
Shingles and Urinary Retention: A Complex Connection
Urinary retention is an uncommon, but recognized, complication of shingles. It’s estimated to affect up to 28% of individuals who develop shingles around the lower back and sacrum, the area of the spine near the pelvis, according to research cited in the case report. However, the occurrence rate is lower – around 4% – in the medical center where this patient was treated. The underlying mechanism is believed to be inflammation affecting the bladder, the nerves that control bladder function, or nerves near the spinal cord. This disruption interferes with the signals that trigger bladder muscle contraction, leading to urine retention.
The authors of the report emphasize that What we have is the first documented case of bladder rupture directly attributed to urinary retention caused by shingles. “The risk of urinary system dysfunction associated with shingles cannot be ignored,” they wrote. They too noted that the patient’s pre-existing type 2 diabetes may have contributed to his symptoms, as diabetes can cause nerve damage that impairs the sensation of a full bladder.
Recognizing Shingles Symptoms and Seeking Prompt Care
Shingles typically begins with pain, itching, or tingling in a specific area of the skin, followed by a rash of fluid-filled blisters. The rash usually appears on one side of the body, often in a band-like pattern. Early diagnosis and treatment with antiviral medications can help reduce the severity and duration of the illness, and potentially lower the risk of complications. The Centers for Disease Control and Prevention (CDC) provides comprehensive information about shingles, including symptoms, treatment, and prevention, at https://www.cdc.gov/shingles/index.html.
While bladder rupture is an extremely rare outcome, this case underscores the importance of being vigilant for any urinary symptoms – difficulty urinating, a feeling of incomplete bladder emptying, or lower abdominal pain – in individuals with shingles, particularly those with underlying health conditions like diabetes. Prompt medical attention is crucial to prevent serious complications.
The development of a vaccine against shingles, Shingrix, has significantly reduced the incidence of the disease and its complications. The CDC recommends Shingrix for adults aged 50 years and older, even if they have had shingles before. Vaccination is the most effective way to prevent shingles and its associated health risks.
Further research is needed to fully understand the link between shingles and urinary dysfunction, and to identify individuals at highest risk for this rare but serious complication. Healthcare providers should remain aware of this potential association and consider urinary retention in the evaluation of patients with shingles, especially those presenting with abdominal pain or difficulty urinating.
