INTRODUCTION. Ureter lithiasis is a concern for physicians because frequently provokes an obstructive uropathy and a progressive deterioration of ipsilateral renal function and a high prevalence of pathological state that is why the hospitals can not give a surgical solution as quickly as possible. The objective of present research was to know the results of the shock waves extracorporeal lithotripsy (SWEL) using the MODULITH SLX-MX (STORZ) lithotriptor for treatment or ureteral lithiasis. METHODS. In present research 598 patients presenting with ureter radiopaque lithiasis, seen in the "Hermanos Ameijeiras" Clinical Surgical Hospital from January, 2007 to December, 2008, divided into four groups according to the calculus localization: in pyeloureteral joint (PUJ) (96), lumbar ureter (LU) (263), iliac joint (IJ) (40), pelvic joint (PJ) (199) analyzing its relationship with lithiasis surface, treatment sessions, complementary manoeuvres previous to lithotripsy, application of subsequent auxiliary procedures, definite resolution using other surgical technique and therapeutical effectiveness. Collimation was carried out by fluoroscopy. RESULTS. Most of calculi were located in the lumbar ureter and in the second place in pelvic ureter. The mean size of lithiasis was of 0,8 ± 0,5233 cm² in the rank of 0,09-4 cm². The mean of sessions used was of 1,24 ± 0,531, in the rank of 0,09-4 cm². The mean of sessions used was of 1,24 ± 0,531, rank of 1-4. In 72 patients 12,04%) previous complementary manoeuvres were carried out and the more used one was the percutaneous nephrostomy (40; 6,6%). After SWEL it was necessary the conversion to other procedure for solution of 4,68% of the cases. The SWEL was effective in the 95,32% with better results in the UP (96,99%) and with worse results in the IJ (92,50%). CONCLUSIONS. The results were good using the MODULITH SLX-MX (STORZ) lithotriptor. The better results were obtained in the pelvic ureter and in general, it is possible to consider the SWEL as the first therapeutical choice of ureteral lithiasis.
