Risks: balancing harm and benefit. A Vohrah. When ever considering a test or procedure?. Is there a better investigation which can give the us the answer? Consider safety, accuracy (sensitivity and specificity), cost, and what is available.
What can I damage on introduction?
What other problems may occur?
A wire is introduced down the needle.
The kidney is punctured
With the patient in the prone position under ultrasound control
A tube is pushed over the wire and left in the kidney,
Occasionally one needs to embolise an AVM or bleeding kidney as a consequence of nephrostomy
Operative mortality is lower(1.8 vs 4.3%)
Not fit for surgery-30 day mortality is 7.3%. Re intervention rate is high. Less died of ruptured aneurysm. Overall mortality unchanged.
General mortality advantage over surgery for 1-3 years after repair.
Overall more expensive due to follow up and re intervention.
Stent technology is however improving all the time.
So if you are unfit for surgery are we just changing the modality of death and not prolonging life?
