Comparison of shockwave lithotripsy and flexible ureteroscopy for the treatment of kidney stones in patients with a solitary kidney.

Introduction And Objectives: To compare the outcomes of these minimally invasive procedures in this patient population.

Patients And Methods: The database of our institution has been retrospectively reviewed, and medical records of urolithiasis patients with a solitary kidney who underwent flexible ureteroscopy (F-URS) or extracorporeal shock wave lithotripsy (SWL) between January 2009 and December 2012 were examined. Retreatment rates, complications, changes in estimated glomerular filtration rates (eGFRs), chronic kidney disease (CKD) stages, and stone-free rates were compared between the two groups.
