Effectiveness of Self-posturotherapy on the Elimination of Residual Fragments After Treatment of Lower Calyx Urinary Stones by Extracorporeal Lithotripsy or Retrograde Flexible Ureteroscopy.
The main objective of this study is to evaluate the effectiveness of an auto posturotherapy technique on the RFS at three months of patients treated for lower calyceal urinary stones by extracorporeal lithotripsy (ECL) or retrograde flexible ureteroscopy.
• Patient having read and signed the consent form for participation in the study • Patient candidate for an intervention on a lower calyx stone \<15mm by LEC or URSS
⁃ Patients meeting all of the following criteria may be definitively included in the study:
• Patient treated by LEC, or patient treated by URSS and for whom the presence of lower calyceal fragments has been observed by endoscopy
• Absence of JJ stent (patients for whom a JJ stent was implanted after URSS or before LEC may be included as soon as it is removed)
