Abstract

OBJECTIVES: Extracorporeal shock wave lithotripsy is a minimally invasive therapeutic option for the treatment of renal-ureteral lithiasis. The aim of this study was to analyze the results and complications of shock wave extracorporeal lithotripsy treatment with the Dornier Gemini® Generator EMSE 220f-XXP device in patients with renal and ureteral lithiasis. MATERIAL AND METHODS: Retrospective study including 377 patients with renal or ureteral lithiasis with indication for treatment with extracorporeal shock wave lithotripsy. The following variables were analyzed, age, sex, body mass index, lithiasis size, lithiasis location, presence of urinary diversion, number of lithotripsy sessions, number of shock waves, fluoroscopy time, wave energy, applied focal energy coefficient, efficiency coefficient, lithiasic fragmentation, lithiasic clearance, residual lithiasis, presence of lithiasis and complications. The results were analyzed with SPSS 17.0 considering statistical significance p≤0.05. RESULTS: Of the 377 patients, 213 were men and 164 women, with a mean age of 51.28 ± 12.77 years. The mean size of the stones in maximum diameter was 11.77 ± 6.13 mm. Lithiasis fragmentation occurred in 81.9% of cases, with a percentage of residual lithiasis after the first session of 58.7% and a total or partial expulsion rate of lithiasis fragments of 68.3%, with global success at the end of sessions of lithotripsy of 69.8%. The overall Efficiency Ratio was 0.42, higher in upper calyx 0.51 and lower in medium calyx 0.35, with significant differences (p<0.05). The only differences were found in relation to the success of lithotripsy treatment (75% versus 64.6%, p=0.02), according to lithiasis size (≤10 mm maximum diameter in comparison to >10 mm). In patients with a DJ catheter there is a higher percentage of residual lithiasis (p=0.006). CONCLUSIONS: Treatment with extracorporeal lithotripsy in small lithiasis and in well-selected patients obtains good results with a low rate of complications regardless of sex and body mass index.
