Use and Efficacy of Urethral Stents

Allium stent is a medical device designed to treat urethral strictures in the field of urology. Thanks to its flexible and durable structure, it effectively opens the urethral stricture and normalizes urine flow. Because this stent is made of biocompatible materials, it is easily accepted by the body and is suitable for long-term use.

Urethral stents are small tubes used to widen narrowed areas in the urethra and restore urine flow. These stents are preferred, particularly for short and superficial strictures. However, due to their low long-term success rates and high risk of complications, they are not widely used today.

Complications and Patient Satisfaction

The following complications may occur after urethral stent placement:

Stent Displacement: The stent fails to remain in the desired position and shifts.

Burning and Pain During Urination: Patients experience burning, pain, and stinging sensations while urinating.

Risk of Infection: The possibility of developing urinary tract infections.

Due to these complications, patient satisfaction remains below 30%.

Features and Advantages of Allium Stents

Allium stents are innovative medical devices used in the treatment of urological strictures. Manufactured from nitinol alloy, these stents are coated with a special polymer coating. This coating prevents intratissue growth, thus preventing stent occlusion and reducing the risk of calcification.

The main advantages of Allium stents are as follows:

Long-Term Use: The ability to remain in the body for up to 3 years eliminates the need for repeated procedures.

Easy Installation and Removal: Thanks to its self-expanding structure, it is easy to install and remove.

High Flexibility: Its flexible structure ensures minimal discomfort and maximum patient comfort.

How is an Allium Stent Applied?

Preparation: The patient's general condition is assessed and appropriate anesthesia is administered.

Placement: The stent is inserted into the urethra using a special technique.

Fitting: The stent fits snugly into the narrowed area, opening the urinary tract.

Follow-up: The stent is monitored to ensure it is correctly placed and functioning effectively.
