    Abstract:
    PURPOSE: This study compared the immediate and long-term results and complications of hot-wire balloon endopyelotomy and ureteroscopic holmium laser endopyelotomy. PATIENTS AND METHODS: Between March 1994 and January 2002, 64 patients with a primary (N = 52) or secondary (N = 12) ureteropelvic junction obstruction underwent retrograde endopyelotomy using either a fluoroscopically guided hot-wire balloon incision (N = 27) or a ureteroscopically guided, direct-vision holmium laser incision (N = 37). This study group included 46 women and 18 men aged 13 to 79 years (mean 38.9 years). The indications and contraindications to a retrograde approach were identical in each group and included documented functionally significant evidence of obstruction, no upper-tract stones, obstruction <2 cm, and no radiographic evidence of entanglement of crossing vessels at the ureteropelvic junction. Immediate and long-term outcomes were obtained from a prospective registry, with success defined as resolution of symptoms and radiographic relief of obstruction as determined by follow-up with intravenous urography, diuretic renography, or both. Follow-up ranged from 39 to 133 months (mean 75.6 months). RESULTS: Length of hospital stay, indwelling stent duration, and long-term success rates (77.8% v 74.2% in the hot-wire balloon and holmium-laser group, respectively) were equivalent. However, two patients in the hot-wire balloon group developed bleeding necessitating transfusion and selective embolization of lower-pole vessels. No patient in the ureteroscopic group suffered a major complication. CONCLUSIONS: These two alternatives for retrograde endopyelotomy provide comparable success rates for similarly selected patients. However, because significant hemorrhagic complications developed with greater frequency in those treated with the hot-wire balloon, our preference is for a ureteroscopic approach, as it allows direct visual control of the incision and thus, a lower risk of significant bleeding.
