Complications that can arise after partial kidney removal include blood loss, infection, damage to tissues or organs, hernias or leaking urine, says Johns Hopkins Medicine. In the case of a laparoscopic partial nephrectomy, the surgeon may need to convert to an open surgery. This means a larger incision and a longer recovery period for the patient.
Blood loss during a laparoscopic partial nephrectomy is rare and often minor, says Johns Hopkins Medicine; however, the kidney can bleed from the surgical wound, says The James Buchanan Brady Urological Institute. When this happens, the patient feels pain in the abdomen or flank. Bruises may appear on his side, and there may be blood in his urine. Sometimes, bed rest is enough to resolve the condition. In other cases, the patient needs to undergo a procedure called an angioembolization.
Another complication happens when urine leaks out of the surgical wound in the kidney, says The James Buchanan Brady Urological Institute. This problem often resolves on its own, or the surgeon can insert a stent to guide the urine into the ureter.
Though the medical staff gives patients antibiotics before the operation, infection is another complication of partial kidney removal, according to Johns Hopkins Medicine. A patient with an infection develops a fever, painful and frequent urination, and drainage from the surgical site.
