Jeff,
Per my husband, the good news is the BCG catheter is much smaller in diameter than what's used for cystoscopy or TURBT procedures. The bad news for him, even with lidocaine, the insertion was uncomfortable. The volume of BCG is relatively small and he has been able to retain the BCG for 2 hours each time. We'd drive home right after the instillation with a lunch break at the 2 hour mark. He'd void the BCG into a travel urinal and carry that home to empty into the toilet for the bleach treatment.
Before BCG treatments, I worried unnecessarily about extreme fatigue or other severe side effects my husband might experience. Other than one night of a low grade fever, his side effects have been frequency and burning/discomfort for a day or so after BCG.
Best wishes on your treatment.
