[Toplam: 1 Ortalama: 5]

Why Is Bladder Expansion Surgery Performed?

Bladder dilation surgery is necessary for urinating , protecting the kidneys and comfort.

The task of the urinary bladder is to store the urine coming from the kidneys in a certain capacity and to discharge it by working in harmony with the nervous system when the appropriate ground is found.

Urine is produced in the kidneys and comes to the bladder through the ureter tubes. When the bladder, which has a normal storage capacity of approximately 500 cc, is found to be a suitable environment for urinating, that is, when we go to the toilet, it receives the fitness signal from the brain for urination and the bladder muscles begin to contract.

Meanwhile, the bladder neck begins to open and discharges the urine in the bladder until there is no more urine. This discharge task occurs due to the communication between the cerebrospinal cord and the bladder.

In this triple system, when there are problems in the cerebrospinal cord and bladder, the discharge task cannot be performed. As a result, we face serious problems such as kidney failure, urinary incontinence, and frequent urination.

Especially in diseases that affect the nervous system, namely the cerebrospinal system, the bladder becomes smaller, its capacity decreases, and the patient has serious problems as mentioned above.

Sometimes bladder functions can return if the underlying problem is corrected. However, in most of these problems, the functions do not return and the bladder cannot fulfill its function properly.

Which Patients Is Bladder Expansion Surgery Performed?

Bladder augmentation cystoplasty (bladder widening) is a condition called neurogenic bladder in children with congenital nervous system distress, in cases of neurogenic bladder that develops in subsequent nervous system damage, in cases where a large part of the bladder is removed in cases such as cancer, tuberculosis, bladder after recovery of some infective events It is done when it impairs its contractility.

Is Pre-Surgery Preparation Required?

Since patients require preoperative preparation, they are admitted to the hospital the day before the operation. Take only liquid food and enema 3 times a day. On the morning of the surgery, we have current routine laboratory findings such as urea creatinine, sodium potassium, and blood sugar. Since the operation will take a long time, compression stockings are worn and taken into operation.

How Long Does Bladder Expansion Surgery Take?

Bladder capacity in these patients is very low despite receiving all medical treatments. In the urodynamic tests performed, the pressure inside the bladder is usually very high.

High pressure in the bladder also causes impairment in the kidneys. The aim is to reduce the pressure inside the bladder, protect the kidneys and increase the capacity.

For this, a piece is taken from the small intestine with approximately 15-30 cm vessels as needed and the intestine taken to the upper part of the bladder is opened and sutured. So a wide patch is made.

In the future, this placed intestine adapts to the bladder. It is an operation that takes about 3-5 hours. Hospital stay is 5-7 days.


What are the complications of bladder dilation surgery?

In the early and late period, adverse events, i.e. complications, may develop. In the early period, cases such as clotting from the leg to any part of the body (lung, brain), lung infection, leakage from the intestine, and kidney infection may occur rarely.

Although it is rare, cases such as stenosis in the small intestine section where we take pieces in the late period, nausea, vomiting, leakage in the bladder section where we patch, kidney and urinary tract infection can occur.

In addition, since the intestine used for dilation continues to secrete mucus, we can also see mucus urination for a long time.

What are the Benefits of Bladder Dilation to the Patient?

Conditions that seriously disturb the patient and impair his comfort, such as urinary incontinence, frequent urination, sudden urination sensation, and the feeling of continuous urine will either completely recover or decrease.

On the other hand, kidneys will be protected and fulfill their functions more comfortably due to the decrease in bladder pressure.
