Variation and Correlation in Postoperative Imaging After Shockwave Lithotripsy and Ureteroscopy by Treatment Modality: Results of a Statewide Clinical Registry.
OBJECTIVE: To understand how patient, practice/urologist-level factors impact imaging after ureteroscopy (URS) and shockwave lithotripsy (SWL).
METHODS: Using the Reducing Operative Complications from Kidney Stones (ROCKS) clinical registry from the Michigan Urological Surgery Improvement Collaborative (MUSIC), we identified patients undergoing URS and SWL between 2016-2019. Frequency and modality of 60-day postoperative imaging was assessed. We made bivariate comparisons across demographic/clinical data and assessed provider/practice-level imaging rate variation. We assessed correlation between imaging use within practices by treatment modality. Multivariable logistic regression controlling for practice/urologist variation was used to adjust for group differences.
RESULTS: 14,894 cases were identified (9621 URS, 5273 SWL) from 33 practices and 205 urologists. Overall postoperative imaging rate was 49.1% and was significantly different following URS and SWL (36.3% vs 72.4%, P
CONCLUSION: Imaging rates after URS are almost half the rate for SWL with wide variation, underscoring uncertainty with how postoperative imaging is approached. However, practices who have higher post-URS imaging rates also image highly after SWL. Increased patient complexity and renal stone location drive imaging following URS.
