Urethral stents
A urethral stent is a surgical device that is placed in the urethra. The stent is placed in a way that the urethra is not affected. This stent holds the urethra's lining in place. It is unlikely to migrate or dislodge and is non-reactive to the body tissues. Some complications may occur during the procedure, including pain when urinating and leakage of urine.
The procedure may be done with local or general anesthesia. The anesthesia numbs the area around the urethra, but it may still involve pushing, pressure, and pain. The healthcare provider will use an endoscope to guide the catheter into the urethra. The endoscope has a light and camera on its tip. The healthcare provider will use a contrast liquid to make sure the urethra is completely obstructed before inserting the stent.
While there are currently several types of urethral stents, not all of them have been proven to be as effective. A biodegradable urethral stent is another option for treating a nephrosis. It will degrade over time, and is biodegradable. However, this type of stent should be carefully chosen as it is not suitable for every patient.
After the procedure, the urethral stent will remain in the urethra. After about six months, the urethral stent can be removed. There are risks and benefits associated with this surgery. The main disadvantage of this device is that it cannot be removed. This makes the procedure risky and it is important to consult with a doctor before undergoing any invasive surgery. This procedure is recommended for patients with a narrowed urethra.
The procedure itself may be painful. The stent may be inserted into the urethra through a thin wire. A catheter is then placed over the wire. A balloon is attached to the catheter and this expands the urethra. The stent is then inserted into the urethra. It can be retrieved after a few days or after a few weeks.
After a successful urethral stent, the implanted device can be easily removed. The stent is made from a nickel-titanium alloy. It expands when heated and softens when cooled. The stent is inserted using a sterile fluid and is cooled to reduce the risk of infection and postoperative infections. A doctor will place a catheter and remove the stent at the end of the procedure.
A urethral stent can help with difficult and recurrent urethral strictures. The procedure is usually completed after dilating and incising the stricture. Afterwards, the stent is removed after three to six months and can be removed in the case of a recurrence. Occasionally, the stent can be used to treat scarring of the bladder neck, but in some cases it is not the most effective option.
