Objective To summarize the curative effect of ureter negative stones. Methods Epidural lithotripsy (ESWL) and intravenous pneumatic lithotripsy (URSL) were used to treat 152 patients with ureter negative stones. Results Of the 152 patients, 110 were treated with ESWL assisted ureteral catheterization or intravenous pyelography. One procedure succeeded in 78 cases, 20 cases completed 2 to 3 times, and 6 patients received URSL treatment. Forty-two patients were treated with URSL, 34 cases were discharged, 4 cases were residual, combined with ESWL, stones were discharged. Conclusions Auxiliary ureteral intubation or intravenous pyelography of ESWL and URSL is an economical, effective and safe method for the treatment of ureteral negative stones.
