At Allium Medical, we understand how overwhelming it can be to deal with urological conditions such as strictures, blockages, or postoperative complications.
Therefore, we have developed a unique family of long-lasting stents designed to provide you with immediate relief, restore natural urine flow, and improve your daily life; all without invasive and unnecessary open surgery.
Why Choose Allium?
Emergency Aid
Patients experience significant symptom relief immediately after the procedure.
A minimally invasive, short procedure.
Our stents are typically placed through the body's orifices using minimally invasive techniques, usually under local or short-term general anesthesia (commonly between 15 minutes and 1 hour). Hospital stay is minimal, and discharge is rapid.
Comfort and Quality of Life
No invasive surgery requiring weeks of recovery and pain, no re-hospitalization for double J tube replacement, no need for long-term nephrostomy, no permanent changes to your body; instead, it's designed for comfort, painlessness, and quality of life over time. Minimal recovery time and mild potential side effects.
Long-term and reversible.
Stents can remain in place for up to 3 years and can be easily removed earlier at your doctor's discretion.
Even in complex or recurrent cases, we work closely with your medical team to offer the safest and most effective treatment tailored to your specific needs. Allium stents are used worldwide and are CE approved for use in a variety of benign and malignant (internal obstruction or external compression) urological conditions.
Etiologies vary, including benign and malignant, short and long strictures (external compression and internal) resulting from stones, thermal damage, ischemic causes, idiopathic causes, iatrogenic causes, retroperitoneal fibrosis, peritoneal carcinomatosis, external tumors, internal malignancies, and more.
Urethral/Ureteral Stricture
Urethral stricture is an area of hardened tissue that narrows the urethra and sometimes makes urination difficult. Strictures usually occur in the bulbar section of the male urethra and are quite rare in female patients.
Causes of Urethral/Ureteral Strictures
Urethral strictures can result from inflammation or scar tissue caused by transurethral/ureteral surgery, urethral disease, or injury. The risk is increased in men with a history of sexually transmitted diseases, recurrent urethritis attacks, or benign prostatic hyperplasia. The risk of urethral stricture also increases after injury or trauma to the pelvic region. Any instrumental intervention in the urethra (catheterization or cystoscopy) increases the likelihood of developing urethral stricture.
There has been a steady increase in the number of prostate surgeries performed using transurethral (TUR-P, TUI-P, TUV-P) techniques. In addition, the development of upper urinary tract (ureter and kidney) endo-urological procedures performed through the urethra has significantly increased the risk of developing bulbar urethral stricture.
Urethral/Ureteral Stents
The term "stent" is defined as a thread, rod, or catheter located in the lumen of tube-shaped structures, used to provide support during or after anastomosis, or to restore the patency of an intact but narrowed lumen.
