INTRODUCTION: The internal structure of @entity1290 can be determined on CT using bone windows, and may be classified as homogeneous or inhomogeneous with void regions. In vitro studies have shown homogeneous stones to be less responsive to shock wave lithotripsy (SWL). The objective was to evaluate whether the internal morphology of calculi defined by CT bone window influences SWL outcome in vivo. MATERIAL AND METHODS: 111 @entity1 with @entity1290 treated with SWL were included. Treatment data were registered prospectively and follow-up data were collected retrospectively. All @entity1 had @entity19382 performed prior to SWL and at three months follow-up. The stones were categorized as homogeneous or inhomogeneous. At follow-up the @entity1 's stone status was registered. Stone free status was defined as no evidence of calculi on @entity19382 . Treatment was considered successful if the @entity1 was either stone free or had @entity922 ( @entity922 ). RESULTS: Using simple logistic regression, the odds for being stone free 3 months post-SWL were significantly reduced in the @entity1 with inhomogeneous stones compared to @entity1 with homogeneous stones (OR=0.43 (95% CI: 0.20 - 0.92; P <0.05)). However, when adjusting for stone size by multiple logistic regression including stone size (area) as a covariate, this difference became insignificant. CONCLUSION: The internal structure of @entity1290 did not predict outcome of SWL in vivo.

XXXX as a predictor for shock wave lithotripsy success.
