Abstract OBJECTIVE: To assess the effectiveness of extracorporeal shock wave lithotripsy (ESWL) and percutaneous nephrolithotomy (PCN) as a treatment for stones of the lower pole of the kidney and to compare their morbidity according to the stone size. METHODS: We retrospectively studied 739 patients treated for a single stone of the lower pole. Group I consisted of 666 patients treated by ESWL and group II consisted of 73 patients treated by PCN. RESULTS: These were assessed at 3 months for 587 ESWL patients (88\%) and at day 1 for all PCN patients on renal tomography or ultrasonography. Respectively in groups I and II, 335 patients (57\%) and 53 patients (72.6\%) were stone-free (p = 0.01). For medium-size (10-20 mm) stone patients, stone-free represented 102 patients (44\%) and 29 patients (72.5\%) in groups I and II respectively (p = 0.001). For smaller stones (< 10 mm), stone-free represented 231 patients (69\%) and 21 patients (84\%) in groups I and II respectively (p = 0.12). Morbidity rate was less with ESWL than with PCN. CONCLUSIONS: PCN achieves better results than ESWL for single stone of the lower pole with statistical significance for middle-size stones but with higher morbidity.
