[Recanalization of urethral strictures using a temporary curved biocompatible new generation metal endoprosthesis]].
The male urethral stricture treatment is actual clinical issue with its resolution being increasingly frequently based on application of minimum invasive therapeutic interventional uroradiology methods. Since the methodology is applied over the last two decades, the most reasonable therapeutic algorithm has not been defined yet with respect to the correlation with the contemporary surgical treatment. The results of application of the temporary covered self-expandable nitinol Allium stents, which have been applied for the first time ever at our Institution in October 2003. Over the last 3 years, the method was applied in 40 males, averagely aged 54 years with urethral strictures previously treated by urological methods. In four cases, stent placement was performed after endourethral incision. The most common etiology of the stricture was the posttraumatic (55%), post-inflammatory (32%) and iatrogenic (10%). In all the cases, stents were removed 12-14 months after their insertions. The results are evaluated using uroflowmetry and urethrocystography, revealing in 85% of the cases permanent recanalization free of dysuric complaints. Development of a stricture on the anterior stent end was evidenced in 15% of the cases.
