Bladder cancer is a prevalent urological malignancy characterized by the uncontrolled growth of cells in the bladder lining. It primarily manifests as transitional cell carcinoma, though other histological types exist. Risk factors include smoking, exposure to certain chemicals, chronic bladder inflammation, and genetic predispositions. Symptoms often present as hematuria, urinary frequency, and dysuria, prompting diagnostic evaluations like cystoscopy and imaging studies. Management of bladder cancer involves a multimodal approach, including surgical intervention, chemotherapy, immunotherapy, and radiotherapy, tailored to the stage and grade of the tumor. Early detection significantly improves prognosis, emphasizing the importance of regular screening in high-risk populations. Ongoing research focuses on identifying molecular markers for better diagnosis, prognostication, and targeted therapies. The length of hospital stay (LOS) following surgery is a critical indicator of clinical outcomes and resource utilization. Both organizational and patient-related factors can significantly affect LOS, making it essential to understand the reasons that lead to extended hospital stays in order to improve patient care. The LOS after bladder cancer surgery at the Antonio Cardarelli Hospital in Naples, Italy, is examined in this study using a statistical learning technique. It builds on past studies on surgical oncology's causes of extended length of stay. The main findings showed how hospital stay duration is impacted by the clinical and organizational aspects of the surgical process, offering a chance to enhance patient care and quality.
