Analysis in terms of patient perception :comparison of patient satisfaction with treatment outcomes between ureteroscopy and shock wave lithotripsy for ureteral stones

==inizio abstract==

There are few studies regarding patient′s subjective satisfaction between shock wave lithotripsy (SWL) and ureteroscopic lithotripsy (URS) for ureteral stones.This is our objective
2.Materials and results:
From March 2013 to January 2014, we prospectively evaluated 44 consecutive patients who underwent SWL (n=19) or URS (n=25) for a single radiopaque ureteral stones. Stone-free rates (SFRs), defined as no visible fragment on plain X-ray, complications and patient satisfaction were compared between the two groups. Patients′ satisfaction was examined through specifically tailored questionnaire which includes 4 domains (pain, hematuria, voiding symptom and recovery to routine performance status), overall satisfaction (5 scales) and willingness to retreatment.The SFRs after the first, second, third sessions SWL were 52,3%, 80,0%, 100%, respectively. Mean time to stone-free status in the SWL group was 18.5 days (range 3-24 days), and 4 patients of SWL group were converted to URS after the first session of SWL due to refractory pain. The SFR after URS was 100%, which was significantly better than SFRs of the first and second session SWL (p<0.001, p=0.046, respectively). Complications were comparable in the two groups, except that gross hematuria lasting for more than 48 hours was relatively more common after URS than SWL (75,4% vs 56,3%, p = 0,081).Satisfaction score in pain and hematuria domain and overall satisfaction score was similar between the groups, whereas satisfaction score in voiding symptom and recovery to routine performance status was significantly better in the SWL group than URS group (p<0.001, p=0.039, respectively). For retreatment, 67.6% of SWL and 58,2% of URS group had willingness to the same treatment method (p=0.309). 3.Discussion Our results indicate that both SWL and URS as the initial treatment modalities of ureteral stones were associated with high SFRs and similar complication rates,overall patient satisfaction. ==fine abstract==
