Abstract
Primary ureteropelvic junction obstruction (UPJO) today is mainly treated by antegrade endopyelotomy. Ureteroscopic retrograde endopyelotomy using a KTP-laser is a new and promising treatment modality for primary UPJO. A semi-rigid Ch. 9.5 continuous flow ureteroscope (Storz) is used. Lateral incision is performed at a power setting of 5 to 20 W with a 0.4 mm bare fiber or a Ch. 3.6 side-firing device (Laserscope). An endopyelotomy stent is left in place for 6 weeks. Evaluation is usually done with a urogram pre- and postoperatively. Eight patients (2m/6f) with a mean age of 29.5 years have been treated so far. In 6/8 cases the incision was successful. Prolonged stenting occurred in one and laparoscopic division of a crossing vessel because of a persistent obstruction in another patient. In 2/8 patients retrograde endopyelotomy was not possible owing to large lower pole vessels and so open pyeloplasty was performed. Our preliminary results suggest retrograde KTP laser endopyelotomy as a safe and efficient procedure. A first attempt to laser endopyelotomy seems to be justified even in case of crossing vessels and/or large pyelocaliceal volume.
