A kidney stent is a narrow tube that is medically inserted into the kidney and ureter for easing urinary disorders. These tubes are made up of plastic, metal or fabric mesh and help in relieving obstructions in kidneys that can arise due to a host of renal disorders. When a kidney stent is placed in an individual there are some side effects and risks that can occur due to this procedure. While most of the side effects are common and usually disappear with the passage of time patients can suffer from certain complications in some cases.
Complication That Can Arise Due To Kidney Stent Placement
Complications from kidney stents are usually rare, although having awareness about the various risks is very vital in order to avoid any serious health implications.
Infection – Due to the presence of a foreign object in the body there can be a risk of developing urinary tract infections in patients using a kidney stent. An UTI can develop due to bacterial growth in the ureter or when the stent becomes coated with mineral deposits that are present in the urine. The infection can cause high fever, severe pain during urination as well as bleeding.
Displacement – This is a very rare occurrence wherein the stent gets dislodged from its proper position and migrates away from the kidney and usually into the urinary bladder of the patient. This displacement gives rise to a feeling of increased discomfort and pain in the lower abdomen as well as finding traces of blood in the urine. In some cases stent displacement can also result in the puncturing or damage of surrounding organs like the gall bladder and lungs.
Procedural Risks – Stent placement can cause damage to the kidneys or even the arteries in few cases. This complication occurs when the placement in not carried out properly and the renal artery or any other blood vessel becomes bruised during stent insertion. While this nature of damage occurs in less than 2% of patients undergoing kidney stent placement it is very important to ensure that the procedure is carried out with due care and precautions.
Excessive Bleeding – Traces of blood in urine is a minor side effect that is experienced by most patients but when the bleeding becomes so excessive that the urine turns thick with the color of blood it can be a serious cause of concern. Excessive bleeding can be indicative of stent migration, urinary tract infection or even some internal organ damage in some cases.
One of the safest ways to avoid complications is to be aware of any changes or distress signals that you might be experiencing just after a placement procedure. Taking precautions like avoiding excess physical activities and stress as well as drinking up to 2 liters of water daily, will also help in mitigating the above mentioned complications. Always remember that immediate and timely action is your best aid. So make sure to get in touch with your doctor as soon as you experience any of the complications associated with a kidney stent placement.
Summary – Kidney Stent related complications surface very rarely but having awareness about the symptoms makes it easier to be vigilant and avoid any serious health issues. Some of the complications include urinary tract infection, stent displacement, procedural risks and excessive bleeding or severe haematuria.
