Intraoperative vs. Postoperative Intravesical Epirubicin Instillation for Prevention of Bladder Recurrence in High-Risk Upper Urinary Tract Urothelial Carcinoma (IEPBR)

April 22, 2025 updated by: Cagri Akpinar, Ankara Etlik City Hospital

Effect of Intravesical Chemotherapy on Disease Recurrence in Patients Undergoing Nephroureterectomy for Upper Urinary Tract Urothelial Carcinoma

Upper urinary tract urothelial carcinoma (UTUC) accounts for 5%-10% of urothelial malignancies, with up to 50% of patients developing bladder recurrence post-RNU. High-risk UTUC (≥pT2, high-grade, or N+ disease) necessitates aggressive management. Intravesical chemotherapy mitigates recurrence risk, yet optimal timing-intraoperative vs. postoperative-remains unclear. This study evaluates intraoperative epirubicin instillation during RNU compared to postoperative administration and no instillation.
