Supporting Sexual Health in Bladder Cancer Patients: A Sequential Mixed-Methods Intervention Study

Despite increasing recognition of sexual dysfunction and sexual distress as important survivorship issues in oncology, research and clinical attention remain uneven across cancer types. This imbalance is particularly evident in bladder cancer, where sexual health has received limited research and clinical attention. However, existing studies demonstrate substantial sexual dysfunction and reduced intimacy among patients following disease and treatment. The treatment of bladder cancer is a multimodal and multidisciplinary discipline. Low-risk non-muscle-invasive bladder cancer (NMIBC) is treated by transurethral resection of the bladder (TURB) alone, while recurrent intermediate- and high-risk NMIBC undergo a combination of TURB and adjuvant intravesical instillation therapy. For patients with muscle-invasive bladder cancer (MIBC) and specific high-risk NMIBC cases, the first-line treatment option is radical cystectomy with urinary diversion, with or without neoadjuvant chemotherapy. These treatment modalities are known to have a negative impact on sexual function, and studies in both men and women demonstrate profound impairments in sexual function, intimacy, and body image after treatment. Among men, erectile and ejaculatory dysfunction are prevalent for this patient group and frequently associated with diminished sexual satisfaction and body-image concerns. Likewise, women experience loss of sexual desire, orgasmic disorders, dyspareunia, and vaginal dryness following cystectomy. A targeted literature search further identified no contemporary sexology-focused interventional or feasibility trials specifically in bladder cancer (neither MIBC or NMIBC). Existing evidence on the topic is largely descriptive or addresses non-sexological rehabilitation, demonstrating a evidence gap\[1\]. Qualitative research has also explored informational and psychosocial needs among bladder cancer patients, revealing limited communication about sexual health and unmet needs for pro
