The importance of residual calculi on recurrence in patients with infection stones
Traditionally the purpose in all kind of renal stone surgery is to achieve complete clearance of the kidney. It is, of course, still an important task to remove the stone fragments, although in newer operative techniques with percutaneous endoscopic procedures minimal fragments are left behind even if they are not seen postoperatively on radiograms. In patients with infection-induced stone disease, a residual calculus might maintain the infection, sometimes resulting in a very quick stone re-growth. The aim of this investigation was to study the importance of residual calculi regarding the recurrence of stones and infections in patients operated upon for infection-induced stones.
