All of the following are symptoms of hepatic encephalopathy EXCEPT:

Hepatic encephalopathy is a neuropsychiatric syndrome that occurs as a result of liver failure, leading to the accumulation of toxins, particularly ammonia, which affects the brain. Symptoms of this condition can vary in severity and presentation but commonly include asterixis (a flapping tremor), changes in sleep patterns, and alterations in the level of consciousness that can progress to coma.

Asterixis is a classic sign observed in hepatic encephalopathy and presents as a sudden, non-rhythmic interruption of voluntary movements, usually involving the hands. Sleep cycle reversal or disturbances are also frequently seen, where patients may exhibit insomnia or reversal of the normal sleep-wake cycle, leading to increased daytime sleepiness and wakefulness at night. Coma represents the most severe form of alteration in consciousness and is indeed a potential outcome of advanced hepatic encephalopathy.

In contrast, hematuria, which refers to the presence of blood in urine, is not a symptom associated with hepatic encephalopathy. It can indicate conditions related to kidney issues, urinary tract infections, or other systemic problems, but it does not correlate directly with the neurological effects stemming from liver dysfunction. Thus, hematuria does not fit within the typical clinical manifestations of
