Abstract
OBJECTIVES: Endoureterotomy and balloon dilation are techniques that have shown promise as treatment modalities for benign ureteral stricture disease. In this animal investigation, the results of a new endoureterotomy balloon that simultaneously incises and dilates the ureteral stricture via a retrograde approach are discussed. METHODS: Using the female pig model, 9 subjects with benign ureteral strictures were treated: 7 with the endoureterotomy balloon and 2 with balloon dilation only. RESULTS: Success based on radiologic parameters and Whitaker testing was obtained in 5 of the 7 animals treated by endoureterotomy. In both animals treated by balloon dilation only, recurrent ureteral stricture disease developed. CONCLUSIONS: This preliminary investigation suggests that this new device may be an effective treatment for benign ureteral stricture disease and that the further study in clinical trials is warranted.
