Percutaneous nephrostomy (PCN) and DJ stenting are minimally invasive procedures used to treat urinary tract blockages, such as those caused by kidney stones, tumors, or strictures.
During percutaneous nephrostomy, a small incision is made in the skin and a needle is used to access one of the dilated calyces of the kidney. Through the needle,a guidewire is inserted and a catheter is then threaded over the wire and into the kidney to allow for continuous drainage of urine. This can help to relieve pressure on the kidney and prevent further damage.
DJ stenting is a similar procedure in which a thin, flexible tube (stent) is inserted into the ureter, the tube that connects the kidney to the bladder, to help urine flow freely. The stent is usually inserted through the urethra using a cystoscope, a small tube with a camera on the end that allows the doctor to see inside the urinary tract. DJ stenting can also be done via PCN tract.
Both PCN and DJ stenting are typically done under local anesthesia and do not require a hospital stay. However, there are some risks and potential complications associated with these procedures, such as bleeding, infection, and damage to surrounding organs. In some cases, the stent may need to be replaced periodically to maintain urine flow.
The decision to undergo PCN or DJ stenting should be made in consultation with a healthcare provider, taking into consideration factors such as the location and severity of the urinary tract blockage, the patient’s overall health, and their individual treatment goals. In some cases, surgery may be a more appropriate option, particularly for complex or severe blockages.
