Hi,
Noted the history about your friend who has undergone surgery to crush the
urinary system stone followed by stent,
severe pain in stomach on removal of sent.
The commonest causes I can think about for the pain in abdomen on removal of stent are as follows:
Impinging of stone fractions.
Striture.
Blood clot retention.
Urinary tract infection.
Colitis should be also watched for.
This can be diagnosed by the following:
Yes, take him to ER.
Will have tests of urine and blood.
Ultrasonography to see for any stone, enlargement of kidney.
The treatment will be as per the findings.
To take plenty of oral fluids.
Antispasmodic as needed.
All these things will help him for proper diagnosis and management.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
