Hi,
It's treatment is only in the ER for a few days! UTI takes antibiotics,
blood culture, urine culture reports will suggest / depending upon size of
cyst can tell need of surgery or might be rupture that can lead all conditions you mention,
biopsy of intestine will tell diagnosis if needed!
When she get cured she will need strong immune system too, make sure she learns breathing exercises which will help in her future or prevent any relapse too. USG,
HCG, blood urea, Nitro, creat, LFT, RFT, X-rays or biopsy may be needed in her case.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Sunny Madar, General & Family Physician
