The most common problems after treatment are leaking urine or delayed bleeding. These may be treated by using telescopes to reach the urinary tract (“endoscopy”) or angiographic embolization. If these things fail, surgery may be needed. The kidney may need to be taken out.
Another problem is a pus pocket (“abscess”) forming around a kidney. This is treated by draining the infection with a tube placed into the abscess. Sometimes surgery is needed to drain the abscess.
Some patients get high blood pressure after major kidney trauma. This may be treated with medication, interventional radiology (including stent placement), or surgery (including removal of the kidney).
