Morbidity associated with patient positioning in extracorporeal shock wave lithotripsy of distal ureteral calculi.
In 115 patients with 123 distal ureteral stones located below the lower border of the sacroiliac joint, in situ extracorporeal shock wave lithotripsy (ESWL) was performed with a Siemens Lithostar Lithotriptor. Our initial experience with the prone position in 8 out of 49 cases did not reveal stone fragmentation and on the final treatment sessions shock waves were allowed to enter via the obturator or sciatic foramen whilst the patients were in the supine position, in order to compare the results of treatments performed in both positions. The mean number of treatment sessions per patient, mean number of shock waves per treatment sessions, mean shock voltage per session and mean fluoroscopy time per session were significantly lower in the supine group than in the prone group (p < 0.05 for all variables). ESWL of the distal ureteral stones in the prone position seems to have an associated patient morbidity when we compare the results of treatments performed in both positions.
