Acucise Endopyelotomy: Assessment of Long-term Durability

AbstractPurpose: We evaluated the long-term efficacy of Acucise* *Applied Medical Resources, Laguna Hills, California. endopyelotomy.Materials and Methods: A total of 28 patients with 28 ureteropelvic junction obstructions was reevaluated 2 or more years after Acucise endopyelotomy (mean 32.5 months). Subjective analysis was done with analog pain scales and objective analysis was performed with diuretic renal scintigraphy.Results: Subjective followup was available for all 28 patients, and 17 (61 percent) had a favorable response with 36 percent totally free of pain and 25 percent markedly improved. Among 26 patients with objective followup (93 percent) 21 (81 percent) had a patent ureteropelvic junction based on a diuretic renal scan with a half-time of less than 10 minutes or a normal Whitaker test. Among all regularly followed patients failure occurred uniformly within 1 year.Conclusions: Acucise endopyelotomy is an effective and durable method for treating ureteropelvic junction obstruction.
