Purpose.

The COVID-19-induced effects of primary bladder cancer (BC) patients have not yet been clarified. The aim of this study was to investigate the effects of the pandemic on the diagnosis, treatment, and follow-up of primary BC patients.

Material and methods.

A retrospective single-center analysis was made of all patients who underwent diagnostic and surgical procedures due to primary BC between November 2018 and July 2021. A total of 275 patients were identified and allocated to one of the groups: Pre-COVIDBC (BC diagnosed before the COVID-19 pandemic) or COVIDBC (during the pandemic).

Results.

The BC patients diagnosed during the pandemic were mostly at higher stages (T2) (p = 0.04), the risk of non-muscle invasive BC (NMIBC) was higher (p = 0.02), and recurrence and progression scores were increased (p = 0.001) compared to patients diagnosed before the pandemic. The time to surgery from diagnosis (p = 0.001) and symptom duration (p = 0.04) were significantly prolonged during the pandemic and the rate of follow-up significantly decreased (p = 0.03).

Conclusions.

The study results highlight the significant increase in muscle invasive BC and the very high risk of NMIBC in patients presenting during the COVID-19 pandemic.
