A nephrostomy tube is a thin plastic tube that is passed from the back, through the skin and then through the kidney, to the point where the urine collects. Its job is to temporarily drain the urine that is blocked. This allows the kidney to function properly and protects it from further damage.
What comes out of a nephrostomy tube?
It is put in through your skin and into your kidney to drain your urine (pee). You may need a nephrostomy tube when something is blocking your normal flow of urine. Urine from your kidney passes through tubes called ureters.
The Procedure. At the end of your surgery, your doctor inserts a nephrostomy tube through your back and into your kidney. The soft plastic tube is then connected to a drainage bag outside of your body. Your doctor may also insert a nephrostomy tube before surgery to help treat a blockage from a stone.
Flushing the nephrostomy tube with normal saline. If the flow of urine from the tube decreases or stops, the tube may need to be flushed with a salt water solution called normal saline. This clears any small pieces of waste that might be blocking the catheter from draining. Flushing is also called instilling.
This type of urinary diversion includes a nephrostomy and urinary catheterization. A nephrostomy involves a small tube inserted through the skin directly into a kidney. A urostomy is a stoma that connects to the urinary tract and makes it possible for urine to drain out of the body when regular urination cannot occur.
Percutaneous nephrostomy (PCN) tube is a catheter (plastic tube) that is inserted through your skin into your kidney. The nephrostomy tube is placed to drain urine from your body into a collecting bag outside your body.
In the majority of patients, the stents are required for only a short duration, from a few weeks to a few months. However, a stent in the right position can stay in for up to three months without the need to replace it. When the underlying problem is not a kidney stone, the stent can stay even longer.
Stents will last forever if they are made of some sort of metal as most are. There is a new product on the market, a new heart stent that dissolves in the artery three years after being implanted.
Percutaneous nephrolithotomy (PCNL) is a minimally-invasive procedure to remove stones from the kidney by a small puncture wound (up to about 1 cm) through the skin. It is most suitable to remove stones of more than 2 cm in size and which are present near the pelvic region.
Recovery from angioplasty and stenting is typically brief. Discharge from the hospital is usually 12 to 24 hours after the catheter is removed. Many patients are able to return to work within a few days to a week after a procedure.
A ureteral stent (pronounced you-REE-ter-ul), or ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney. The length of the stents used in adult patients varies between 24 and 30 cm.
A percutaneous nephrostomy is the placement of a small, flexible rubber tube (catheter) through your skin into your kidney to drain your urine. It is inserted through your back or flank.
Be aware of these common side effects from a ureteral stent:
- Discomfort and pain, usually experienced as a dull feeling in your sides and groin, and can get worse while you are urinating.
- Blood in your urine.
- A feeling of fullness and a constant need to urinate (urgency and frequency).
A nephrostomy is an artificial opening created between the kidney and the skin which allows for the urinary diversion directly from the upper part of the urinary system (renal pelvis). An urostomy is a related procedure performed more distally along the urinary system to provide urinary diversion.
Your Recovery. A ureteral (say "you-REE-ter-ul") stent is a thin, hollow tube that is placed in the ureter to help urine pass from the kidney into the bladder. You may have a small amount of blood in your urine for 1 to 3 days after the procedure.
A suprapubic catheter is a hollow flexible tube that is used to drain urine from the bladder. It is inserted into the bladder through a cut in the tummy, a few inches below the navel (tummy button).
To place the stent, your doctor will first insert a cystoscope (thin, flexible tube with a camera) through your urethra (the small tube that carries urine from your bladder to outside your body) and into your bladder. They will use the cystoscope to find the opening where your ureter connects to your bladder.
A ureteral stent is a small, soft, tube about 10 - 12 inches long and about as big around as a coffee swizzle stick (see picture above, on left). It is placed in the ureter, which is the muscular tube that drains urine from the kidney to the bladder (see picture above, on right).
There are two ways to remove ureteral stents. Commonly, the stent is removed by cystoscopy, an outpatient procedure which takes only a few minutes. During cystoscopy the Urologist places a small flexible tube through the urethra (the hole where urine exits the body).
An antegrade percutaneous internal/external nephroureteral (PCNU) stent is placed percutaneously, establishing antegrade access to the kidney, ureter, and urinary bladder. A segment of the stent remains outside the patient from the flank, which can be capped or connected to gravity drainage.
Pyeloplasty is the surgical reconstruction or revision of the renal pelvis to drain and decompress the kidney. Most commonly it is performed to treat an uretero-pelvic junction obstruction if residual renal function is adequate.
