As I am bowel incontinent, I can say that after you finish with the urological tests and begin the testing of the anus, sphincter, rectum, and sigmoid colon you will just be having so much fun you will not be able to stand it!
Seriously, for bowel, physical examination of the rectum, anal endoscopy, anal manometry (balloons inserted up your rectum and inflated to various levels to test sensing and ability to defecate), defecogram (they fill your rectum with barium solution and you defecate while being imaged by x-ray video), digital rectal mapping (gloved finger up your anus and then mapping the nerves of the rectal wall while you respond to determine sensory loss). Possibly a colonoscopy but only if you have not had one recently.
Best wishes,
