Objective: This scoping review aims to summarize research on the application of network support for patients with urostomy due to bladder cancer and their caregivers, providing references for establishing a networked care system tailored to China’s national conditions. Methods: A systematic search was conducted across databases, including Web of Science, PubMed, the Cochrane Library, Embase, OVID, CNKI, Wanfang Database, and the China Biology Medicine Disc (CBM), using a combination of free-text terms and subject headings. The search covered the period from the inception of each database to August 6, 2025, with subsequent summary and analysis of the retrieved data. Results: A total of 13 studies were included. Network support platforms encompassed mobile applications, telemedicine platforms, online video conferencing tools, and cloud-based follow-up systems. The core functionalities included educational consultation and information sharing, psychosocial support, complication management, follow-up and interactive support, and electronic health record management. Evaluation metrics comprised quality of life, psychological well-being, self-management abilities, complication control, and care satisfaction. Conclusion: Network support models based on diverse platforms can effectively enhance the quality of home care and health outcomes for patients with urostomy and their caregivers, demonstrating feasibility and potential for widespread adoption. Future efforts should focus on optimizing personalized intervention designs, improving technological accessibility, and refining policy support systems to facilitate the establishment of an integrated hospital-home-community transitional care network.
