Introduction
Shockwave lithotripsy (SWL) is a surgical procedure used in urolithiasis treatment. Several factors can influence its results. This study aims to evaluate “real-world” success rates and identify predictors of treatment success in patients undergoing SWL.
Methods
Adult patients undergoing SWL for urolithiasis at three institutions in Canada and Oman were prospectively enrolled. Treatment success after a maximum of two SWL sessions was assessed by post-operative imaging. Logistic regression assessed for predictors of treatment success.
Results
Between May 2021 and February 2022, 271 patients were prospectively enrolled. Overall success rate was 46.1% after one SWL session, and 58.3% after two …

The Role Of Urinary Modulators In The Development Of Infectious Kidney Stones, Brendan Wallace
Electronic Thesis and Dissertation Repository
The pathogenesis of infectious kidney stones is poorly understood, while equally unclear is the role of urinary modulators and bacteria. An experimental model was created and utilized to test a variety of urinary modulators and bacterial strains commonly associated with struvite and calcium phosphate stones to evaluate their potential roles in influencing crystal formation. Modulators such as acids, citrate, and osteopontin had strong inhibitory effects on infectious crystal formation while the remaining modulators had neutral, mixed, or positive effects. Lastly, it was determined that the presence of urease may not directly lead to calcium phosphate and struvite stones in all …
