[Extracorporeal shock wave lithotripsy of urolithiasis in patients with urinary diversion].

We evaluate the efficacy of ESWL in the management of calculi in patients with urinary diversion. We treated 5 patients who suffered from urinary lithiasis after urinary diversion post cistectomy. We managed the patients with extracorporeal shock wave lithotripsy in monotherapy with a Siemens Lithostar Modularis device. Mean stone size (long axis) was 1.95 cm (range 1 to 3.5 cm). The mean shockwave number per session was 2.6 per patient. Stone free result was 100%. We conclude that ESWL technique can provide acceptable results in patients with urinary diversion and can be used as first choice treatment in these type of patients due to its minimal morbidity and excellent results, equivalent to those achieved in patients without urinary diversion.
