<s>[INST] I am a 50 year old female who has had constant abdominal pain for approx 6 months have had a CT this week which shows markedly hypoplastic right kidney.I had tests done when I was a child which showed congenital absence of right kidney, could this be cause of pain?? [/INST] Hi,You pain could be due to your hypoplastic and diseased kidney.I would suggest that you consult a nephrologist for its proper evaluation and further management, as its your only kidney, so better don't delay the treatment.Hope i have been helpful.RegardsDr. Ashish Verma </s>
