<s>[INST] My husband just had his 2nd hospital procedure w/i two week span of time for kidney stone removal. (not lithotripsy)  He had the stent in for 14 days the first time and then had the procedure repeated today.  The first procedure resulted in questionable removal of stones due to excessive amount of blood in his kidney (left).  The dr said it was like trying to see in a muddy pond.  The repeat procedure seemed to go better today, although still alot of blood.  His body temp is now 95 degrees, 4 hours post surgery.  Should we be concerned?  He is also in an exceptional amount of pain (nurse just gave him dilaudid). HELP!  44 yr old male, 6ft, 212lbs, asthmatic, ADHD w/high triglyscerides. [/INST] Hi, I am very sorry to know about your husband condition. The procedure your husband could have undergone might have been either PCNL (percutaneous nephrolithotomy - removing kidney stone through a small hole in the back) or AIRS (retrograde intro renal surgery - removing kidney stone through natural urinary passage with laser). In both surgeries blood in urine is common. PCNL is associated with more blood loss and pain than AIRS. Your treating Urologist will be closely monitoring your husbands progress using vital signs (pulse rate, blood pressure, urine output), hemoglobin level and ultrasonogram to know the amount of blood loss. Even a Chat Doctor.  There are  </s>
