TURP-like syndrome without surgery: severe dilutional hyponatraemia following prolonged sterile water bladder washouts for radiation cystitis: a case report.

Hydrocephalus is a common neurological disorder marked by the pathological accumulation of cerebrospinal fluid, which leads to ventricular dilation and subsequent compression of surrounding brain tissue. If left untreated, it can lead to intellectual disability, loss of motor function, and irreversible brain damage, severely affecting the patient’s health. Hydrocephalus may be classified as either congenital or acquired. The global prevalence of adult hydrocephalus is estimated at 85 cases per 100,000 individuals. The primary treatment approach is ventriculoperitoneal shunt surgery. The incidence and risk of hydrocephalus are influenced by factors such as age, sex, and underlying causes. Therefore, a comprehensive understanding of hydrocephalus, coupled with early diagnosis and intervention, is essential for protecting public health. With the rapid advancement of the internet era, professional medical knowledge has shifted from traditional offline medical consultations and textbooks to online short video dissemination. Public short video platforms have made the spread of medical information faster and more convenient, enabling the public to access relevant professional knowledge in a more accessible format. Bilibili and TikTok are the largest short video platforms in China, with Bilibili featuring longer videos and TikTok focusing on shorter ones. These platforms attract different demographics, with TikTok popular among younger users and Bilibili favored by middle-aged and older audiences. However, due to the absence of a comprehensive review and oversight mechanism, the quality of these educational videos varies significantly, and some may contain inaccurate information, potentially leading to public misinformation. While several studies have evaluated short-video educational content related to neuroscience topics such as stroke, spinal cord injury, and brain tumors, investigations focusing on hydrocephalus on Chinese short-video platforms remain limited. Notably, hydrocephalus is characterized by an insidious onset and a substantial need for timely public education, underscoring its particular public health relevance. Accordingly, this study seeks to evaluate the content characteristics and overall quality of hydrocephalus-related short videos published on TikTok and Bilibili. The findings are intended to inform strategies for improving video quality, refining platform review mechanisms, and providing the public with reliable and high-quality educational content on hydrocephalus.
