Welcome, @nlc512. I moved your message to this existing discussion:
- Small cell carcinoma of the bladder (SCCB): anyone else? https://connect.mayoclinic.org/discussion/small-cell-carcinoma-bladder-sccb/

I did this so you can read previous posts and connect easily with others who have experience with small cell carcinoma of the bladder, like @nvmoen @tattrigoo @samasama @jimmy2248 @sandielegal @m1985 @serenalux and @predictable. You can read more of their posts in this related discussion:

You're asking great questions.
@sue225 and @sepdvm both wrote fantastic posts about their husbands' experiences with bladder replacement options in these 2 discussions:
- My husband's radical cystectomy experience https://connect.mayoclinic.org/discussion/my-husbands-radical-cystectomy-experience/
- My husband's experience with neobladder surgery for bladder cancer https://connect.mayoclinic.org/discussion/bladder-cancer-and-neobladder-surgery/

I'm forever indebted to these 2 members for sharing their experiences to share with you.
