Various Possible Complications Of Renal Puncture:

(1) Hematuria: the incidence of hematuria under the microscope is almost 100%, which usually disappears within 1 to 5 days after surgery without treatment. When the renal needle is inserted into the calyceal or renal pelvis, gross hematuria may occur, mostly disappearing in 1 to 3 days. In the case of gross hematuria accompanied by blood clots, it can generally be relieved after intravenous drip of VitK1 or pituitrin. It should be noted that hemostatic drugs should not be used at this time, in order to avoid serious consequences caused by urinary tract obstruction. Patients are encouraged to drink more water to ensure a smooth urinary tract. Patients with renal insufficiency should avoid heart failure caused by fruit drinking water and pay attention to urination at the same time. Very few patients with severe bleeding, blood transfusion or infusion, monitoring blood pressure and hemoglobin. If the blood pressure cannot be maintained after rescue, selective renal arteriography should be considered to determine the site of bleeding, and arterial embolization or surgery should be decided.

(2) Perirenal hematoma: the incidence of perirenal hematoma is about 60-90%, which is generally small and asymptomatic, and is mostly absorbed within 1-2 weeks. Larger hematoma is a rare, tear or wear to large and medium-sized vessels especially for kidney artery, puncture in more day, the performance of abdominal pain, waist pain, tenderness, or a wound puncture on side a bit of peng, piercing the lateral abdominal tenderness and bounce painful, serious when blood pressure drops, red blood cell pressure drop, do B to exceed or X-ray can be further confirmed, generally take the conservative treatment, if bleeding, It can be treated surgically.

(3) Low back pain: the incidence of about 17-60%, more than a week disappear.

(4) Arteriovenous fistula: the incidence is 15-19%, and most patients have no symptoms. They typically present with severe hematuria and/or perirenal hematoma, refractory hypertension, progressive heart failure, and lumbago vascular murmurs. Renal angiography is necessary for diagnosis. Most patients heal spontaneously within 3 to 30 months. In severe cases, surgery is performed immediately.

(5) Damage to other organs: due to improper puncture point or too deep needle insertion, organs are damaged, and surgical treatment is required in serious cases.

(6) Infection: the incidence of infection is low, mostly due to lax aseptic measures, perirenal infection or pyelonephritis, such as fever, severe low back pain, increased white blood cell need to be treated with antibiotics.

(7) Death: the incidence of 0-0.1%, due to severe bleeding, infection, organ damage or other systemic complications of death.
