Bladder cancer (BC) is a common aggressive malignancy and Urothelial bladder cancer (UBC) consists of the majority of BC. There is uncertainty regarding the clinicopathologic characteristics of UBCs in younger patients. To investigate the clinicopathologic features of young patients with UBCs. A total of 2825 pathological records of UBC patients, including 42 young patients (≤ 30 years old) and 2783 elder patients (> 30 years old), were retrospectively studied. The stage distribution classified was statistically significant (Χ (2) = 12.25, P = 0.02) between young and old patients; superficial tumors was far more in young patients than in old patients. More young patients tended to be low- and moderate-grade UBCs (Χ (2) = 6.75, P = 0.009). Young patients with superficial UBCs also showed lower recurrence rate, compared to elder patients (Χ (2) = 5.77, P = 0.02). For 5-year survival rate, young patients (93.8%) showed better than elder patients (85.1%) (Χ (2) = 4.01, P = 0.045). Patients younger than 30 years old with UBCs had low-grade and low-stage tumors and exhibited better prognosis than elder patients.
