Background: The democratization of extracorporeal shock wave lithotripsy (ESWL) in the end of eighties was a worldwide revolution in the management of urolithiasis, thanks to Chaussy and al. nowadays, despite all new technologies, ESWL remain very used and allow clinicians to treat patient in the most non-invasive way. Material and methods: In the period between January 2017 and December 2019, 53 patients with isolated lower polar calyceal (LPC) calculi ≤ 25 mm, in patients aged ≥ 18 years, were included in the study. Non-enhanced computed tomography or Intravenous urograms were reviewed to define the LPC anatomy (width of the infundibulum and pelvicalyceal angle) and to determine the size of stones. Only patients with radiopaque stones were included. The stone-free rates were assessed with plain X-ray and ultrasound at 4 weeks. Result: The average age of the patients was 42 years with extremes ranging from 18 to 70 years. A male predominance is noted with a Sex Ratio (M / F) of 1.3. Among the 53 patients treated with ESWL, an overall rate of no fragment (Stone Free) was obtained in 55% of our patients. There were no major complications to report during or after ESWL sessions.
