I would call your doc for sure .. please, let us know how you are doing and take care.
Hello and hope you are doing well.
It is not normal to have blood in stools after lithotripsy. It may not be related to the procedure. Haemorrhoids (piles) is the commonest cause for painless bleeding into the stool. Another cause is fissure in ano, where there is pain while passing motion with bleeding. Other causes are inflammatory bowel disorders like ulcerative colitis and crohn’s disease can produce similar symptoms. Please discuss this with your doctor am sure he will provide further assistance.
Hope this helped and do keep us posted.
