Complications of urethral endoprosthesis and elimination of these complications in patients with urethral stricture
Urethral endoprosthesis is a new trend of minimally invasive treatment for patients with the urethral stricture. From 2005 to 2009 at the Clinical hospital a combined treatment of urethral stricture was performed for 24 men whom 12 temporary and 12 permanent stents were placed after the completion of urethrotomy stage. At different time intervals after the operation, complications were noted in 10 patients: 3- stent migration; 2-stent encrustation; 3-epithelial hyperplasia; and 2-urinary incontinence. A high frequency of complications limits a wide use of urethral stents, and is the basic argument in favor of urethral endoprosthesis exclusively in patients with serious diseases whom other methods for the urination restoration are not effective or counter-indicative. The presented experience shows that a strict indications maintenance, methods of stents installation, and a careful dynamic patient supervision are the preventive measures of the complications.
