title: Treatment of painful caliceal stones.
abstract: Nonmobile caliceal stones cause pain more often than previously appreciated. The character and intensity of the pain differs from typical renal colic. Twenty-six patients with caliceal stones and pain underwent attempted treatment for pain control via stone removal or disintegration: 15 were treated with percutaneous stone extraction (PSE), 10 with extracorporeal shock-wave lithotripsy (ESWL), and 1 required open surgery after failing PSE. One patient had persistent pain after ESWL and subsequently underwent PSE; 25 of 26 patients had complete relief of pain. Morbidity was minimal. Patients with painful caliceal stones should be offered ESWL, followed by PSE if pain persists.
