dc.description.abstractAim: In order to have an idea about the success rates after extracorporeal shock wave lithotripsy ( SWL) in patients with lower- pole stones, we reviewed the caliceal anatomy of the patients treated in our clinic. Patients and Methods: One hundred and ninety- eight patients having at least a 3- month follow- up period, with a single stone located in the lower pole, were included. Lower infundibulopelvic angle ( LIP- A), infundibular width, and infundibular length were measured from standard intravenous urograms taken before initial ESWL. Results: One hundred and thirty patients ( 65%) were male, and 68 patients ( 35%) were female. We found no impact of age, sex, and affected side on the results of ESWL. The overall stone- free rate was 61.1% after 3 months of followup. The stone- free rates were 47.8 and 81.4% in patients with an acute ( <70 degrees) and an obtuse (>= 70 degrees) LIP- A, respectively ( p = 0.007). Taking the infundibular width into consideration, the stone- free rates were 85.4 and 43.2% for favorable and unfavorable angles and widths ( p = 0.003). However, infundibular length and stone sizes were not found to have important effects on a stone- free status ( p = 0.546 and p = 0.283). Conclusion: We conclude that LIP- A (>= 70 degrees) has the greatest impact on the clearance of residual fragments produced by SWL.en_US
