[Evaluation of the results of one session of extracorporeal shock-wave lithotripsy (ESWL) for a single urinary tract stone].
Fourteen hundred seventeen patients with a single stone under either general or epidural anesthesia were treated by one session of ESWL using the Dornier HM3 while 255 cases by one session of ESWL using the Dornier MPL9000 under no anesthesia but only with some analgesics, with 3 months' follow up available in all patients. The ratio of stone location in the kidney vs ureter was 7 to 3 in the Dornier HM3 and 5 vs 6 in the Dornier MPL9000. The overall success rate (stone free and residual stone fragments of less than 4 mm, 3 months after ESWL) was 58% (591 cases/1016 cases) for kidney stones with the Dornier HM3 and 35% (41/117) with the Dornier MPL9000. On the other hand, the overall success rate for ureter stones was 61% (245/401) with the Dornier HM3 and 70% (96/138) with the Dornier MPL9000. The overall success rate for stones of more than 10 mm, was poor when treated by the Dornier MPL9000 compared with the Dornier HM3.
