A urostomy is also known as an artificial bladder outlet or artificial urinary diversion. It is a surgically created drainage of urine through the skin. An artificial bladder outlet can be either permanent or temporary. There are various methods available for performing the operation to create a urostomy.
Here you will find further information as well as selected urostomy specialists and centers.
A urostomy is a surgically created artificial bladder outlet on the surface of the skin. The aim of a urostomy is to drain urine to the outside if the body's own urinary system is unable to do so.
The operation to create the urostomy is called a urostomy. The artificial bladder outlet can be either temporary or permanent.
The term urostomy is derived from

In addition to the urostomy, there are also
These two types of stoma are even more common than a urostomy.
A urostomy is necessary when the urinary system can no longer drain urine to the outside by itself. This may be due to
be the cause. Even after surgical removal of the bladder, an artificial bladder outlet is unavoidable.
Possible reasons for damage to the urinary tract or removal of the bladder include
There are basically four different surgical methods available for creating an artificial bladder outlet:
Ureteral skin diversion is also known as ureterocutaneostomy. Depending on the disease, either
In most cases, surgeons first join the two ureters to form a single urostomy and then drain them. To do this, they connect the shorter ureter to the longer ureter, provided they are long enough.
The urostoma must not narrow, for example due to the formation of scars. To do this, the surgeons insert a thin catheter into the ureter, which keeps the ureter open. This catheter must be replaced by the urologist at regular intervals (approximately every 6 to 8 weeks).
A urostomy using ureteral skin drainage is minimally invasive . This is suitable for patients who cannot be expected to undergo major surgery.

With a conduit, the two ureters are directed into a short, approximately 12 to 15 cm long section of the bowel. This section of bowel is first separated and immobilized. The separated piece of bowel serves as a new connection for the ureter. The surgeon directs it outwards as a urostomy and places it in the abdominal wall.
Depending on which section of bowel is used for the artificial bladder outlet, a distinction is made between
After the operation, so-called ureteral stents are used for the first period after the operation. They ensure that the internal sutures can heal and that urine is excreted evenly.
In some patients, both the bladder and the rectum are so severely damaged that they have to be removed. This means that they are no longer available as excretory organs. In these patients, a urostomy by means of a wet colostomy is an option.
In a wet colostomy, the two ureters are first connected to the colon (colon). This causes urine and stool to mix. The colon is then drained through the abdominal wall onto the skin via the urostomy.
A bag collects the excrement here. It must be emptied from time to time.
In a continent colostomy, an internal urine reservoir (a so-called pouch) is created from parts of the bowel. It acts as a replacement bladder.
This replacement bladder is emptied regularly through a sealable urostomy via an opening in the abdominal wall. A catheter is used for this purpose. The bladder should be emptied every 3 to 4 hours, even at night.
Depending on the surgical technique and parts of the bowel used, this is referred to as
