A new method of treating cystourethroanastomosis stenosis after radical prostatectomy with buccal flap fixation by the nitinol stent (nearest results).

Introduction. Stenosis of cystourethroanastomosis is not common but a serious and social significant complication after radical prostatectomy. The present methods of treatment don’t lead to persistent cure. Currently there is a paucity of effective methods for the treatment of this complication and we necessitate to find out a new option to restore urination and preserve continence at the same time. Clinical cases. We presented three cases of successful treatment of cystourethroanastomosis stenosis after radical prostatectomy. Buccal graft was fixed by the nitinol stent after direct visual optical urethrotomy in the zone of cystourethroanastomosis. In two cases, signs of mild incontinence were noted after stent insertion, which required the use of 2-3 urological pads per day. The stent was removed after 2-3 months in all patients the urination and continence were restored. In one case the stent was removed after 2 months after surgery because of bad pain syndrome. In other cases, the stent was removed endoscopically in 3 months. The advantage of our proposed technique is its minimally invasive nature. Its disadvantage is the possibility of stent incrustation. Conclusion. We described the first experience of a urethral stent placement with fixing the buccal graft with encouraging results. The further researches are needed. This method is technically simple and minimally traumatic thus can be widely used in daily practice.
