Combined oral and local therapy for the dissolution of urinary calculi.

The factors underlying the formation of Ca-phosphate and struvite calculi, as well as the present possibilities for oral and local therapy, their advantages and drawbacks are discussed in the light of published evidence. In this context a clinical case of multiple injuries is reported in which practically complete chemolitholysis has been achieved by combined oral and local therapy. The rapid growth of the calculi and their alarming tendency to recurrence in case of inadequate treatment is emphasized. The therapeutic method used in this case is regarded as suitable for practical purposes.
