It is often believed SWL is an overused treatment method by physicians, so we hoped to characterize patient preferences and identify how past experiences affect a patient's decision between URS and SWL. METHODS An anonymous survey was randomly distributed to 101 patients in our stone clinic. Patients were given a hypothetical scenario of an asymptomatic 8mm lower pole renal stone, and were asked to choose one of three treatment options: 1 OBS (annual x-ray, 40% chance growth to larger than 10mm over4 years and no longer option of SWL, 30% chance over 4 years of moving into ureter, 20% chance of passage). 2 SWL (65% success, 1/1000 risk of serious bleed, 1/100 risk of emergent 2nd procedure). 3 URS (90% success, stent required for 1 week - 80% chance will cause bladder and/or kidney pain - 10% will experience significant discomfort, 1/1000 risk of major ureteral injury requiring major surgery, 1/100 risk of minor injury requiring 2-3 weeks w/ stent). Patients also asked whether they would rather defer the decision to their physician. Answers were correlated to the total number of previous stones passed, date of last stone passage, size of largest stone passed, worst pain from stones, and surgical stone history (stent/SWL/URS/PCNL). RESULTS Patients elected OBS 22.8%, URS 29.7%, and SWL 47.5%. Patients who passed larger stones (p=0.029) and a greater number of stones (p=0.0055) were less likely to choose OBS over surgical intervention. Of the 78 patients who chose intervention, 61.5% preferred SWL over URS. Patients were more likely to choose URS if they previously had a URS (p=0.0064) and stent (p=0.048), while patients were more likely to choose SWL if they had a previous SWL (p=0.019). Surgical choice was not impacted by size of largest stone passed (p=0.46), date of last stone passage (p=0.080), previous pain intensity (p=0.11), previous PCNL (p=0.73), or # of stones passed (p=0.51). 56.4% of patients deferred treatment approach to the physician. CONCLUSIONS Past stone experiences and treatments significantly affect treatment choice. Patients rely on their physician not only to educate them on the alternatives, but also to play an active role in selecting the treatment approach. © 2012 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 187Issue 4SApril 2012Page: e912 Advertisement Copyright & Permissions© 2012 by American Urological Association Education and Research, Inc.MetricsAuthor Information Carl Sarkissian Cleveland, OH More articles by this author Mark Noble Cleveland, OH More articles by this author Jianbo Li Cleveland, OH More articles by this author Manoj Monga Cleveland, OH More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
