A nephrostomy is done to drain urine from your kidney. This needs to be done when urine cannot come out as it normally does. Specific conditions that may cause this include:
A nephroscopy through a nephrostomy may also be used to look at the kidneys and ureters before other procedures are done, such as kidney stone removal. This may also help your doctor make a diagnosis.
Complications are rare. But, no procedure is free of risk. If you are planning to have a nephrostomy, your doctor will review a list of possible complications, which may include:
Factors that may increase the risk of complications include:
You will receive a local anesthetic to numb the skin on your lower back. An IV will be placed. You will receive a sedative, pain medicine, and antibiotics through this IV.
A nephrostomy is usually done in an outpatient setting. You will not need to stay in the hospital overnight. Ultrasound or x-ray images will be used to locate your kidney and guide the doctor. A needle will be inserted through your skin and into your kidney. A contrast material will be injected through the needle to better view the kidney on the x-ray. The catheter will then be placed into your kidney. The catheter will come out of your skin and be attached to a collection bag. A dressing will be placed at the insertion site. Urine will drain from your kidney into the collection bag.
After the procedure, you will be monitored for 8-12 hours to make sure the catheter is draining urine. The urine may appear bloody at first. But, it will clear over time.
You may feel soreness at the insertion site for several days after your nephrostomy. Your doctor will give you medicine to help with the pain.
After the procedure, the staff may give you the following care to make you more comfortable and to help you recover:
You will be able to leave when your catheter is working and you are comfortable caring for it.
