Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.Forum.
Your brother of 50 years had been to hospital for endoscopy
, (it is not clear whether gastroscopy, urithroscopy, colonoscopy
, or some thing else. )
If it is urithroscopy, or ureteroscopy can cause infection, if it is others on possibility of infection to kidney
. If it is perforation the scene will be different, there will be shock
I advise you to consult a surgeon for diagnosis and treatment.
Pain in the lower abdomen suggests urinary tract infection
, stone in the urinary urinary tract, prostatitis
, descending colon infection, etc.
Wishing for a quick and complete recovery.
