[Double J stent for pelvis-ureter junction stricture].

Twenty-one patients (27 ureters) with pelvis-ureter junction stricture were treated by persistent dilatation with indwelling double J stent in the ureter. The double J stents were inserted by means of retrograde cystoscopic approach. The duration of stents left in the ureters was 3 approximately 12 months. Follow-up for 5 approximately 36 months after removed the double J stents showed the extinction of the symptoms, remission of the hydropyonephrosis and improvement of the renal function. The excretion urography and retrograde pyelography showed improvement of stricture in 25 ureters. We suggest that persistent dilatation with double J stent be used as first choice for treatment of pelvis-ureter junction stricture.
