Research progress of intravesical recurrence after radical resection of upper tract urothelial carcinoma / 现代泌尿外科杂志

Urothelial carcinoma (UC) is the second most common genitourinary tumor, and upper tract urothelial carcinoma (UTUC) accounts for 5% to 10% of UC. Intravesical recurrence (IVR) occurs in 22% to 47% of patients after radical resection. This article reviews the mechanism, characteristics, related risk factors, regular bladder monitoring, diagnosis and treatment, and preventive measures of IVR, hoping to provide reference for clinical work.
