Antegrade Ureterolitholapaxy in the Treatment of Obstructing or Incarcerated Proximal Ureteric Stones

Abstract

Extracorporeal shockwave lithotripsy (ESWL) and retrograde ureterorenoscopy (RU) have transformed the management of ureteric calculi. Nevertheless, patients with obstructing proximal ureteric calculi are not suitable for ESWL or RU. From January 1986 to September 1988, 17 patients with fixed upper ureteric stones underwent antegrade renoureteroscopy and percutaneous surgery. The technique was effective in removing incarcerated proximal ureteric calculi: all patients were stone-free at follow-up 3 months later.
