During follow-up, he required long-term use of a penile clamp to manage urination due to permanent severe stress incontinence. In February 2023, he presented with a painless cystic mass in the scrotum. Upon pressing the mass with hand, fluid drained from the external urethral orifice, causing the mass to shrink in size, although it returned to its original size a few hours later. Urography and cystoscopy showed a globular urethral diverticulum located anteriorly. The patient underwent surgical excision of the diverticulum along with urethroplasty. Postoperatively, the urinary stress incontinence persisted, but he declined further surgical intervention. An artificial urinary sphincter is currently the first-line treatment for male urinary incontinence. However, devices such as penile clamps can serve as an alternative when considering surgical suitability or cost. It is important to note that these devices can lead to serious complications such as urethral erosion, stricture, or diverticulum. Therefore, caution is advised when using such devices, and they should be removed periodically at short intervals.</p>","PeriodicalId":35615,"journal":{"name":"Chinese Medical Sciences Journal","volume":" ","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143701704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vast volume of data generated by these diseases, spanning from the molecular mechanisms within cells to large-scale epidemiological patterns, has surpassed the capabilities of traditional analytical methods. In the era of artificial intelligence (AI) and big data, there is an urgent necessity for the optimization of these analytical methods to more effectively handle and utilize the information. Despite the rapid accumulation of data associated with viral infections, the lack of a comprehensive framework for integrating, selecting, and analyzing these datasets has left numerous researchers uncertain about which data to select, how to access it, and how to utilize it most effectively in their research. This review endeavors to fill these gaps by exploring the multifaceted nature of viral infectious diseases and summarizing relevant data across multiple levels, from the molecular details of pathogens to broad epidemiological trends. The scope extends from the micro-scale to the macro-scale, encompassing pathogens, hosts, and vectors. In addition to data summarization, this review thoroughly investigates various dataset sources. It also traces the historical evolution of data collection in the field of viral infectious diseases, highlighting the progress achieved over time. Simultaneously, it evaluates the current limitations that impede data utilization. Furthermore, we propose strategies to surmount these challenges, focusing on the development and application of advanced computational techniques, AI-driven models, and enhanced data integration practices.
