The clinical data of 32 patients with pyelogenic cyst were reviewed retrospectively. The diagnosis of 25 cases was confirmed by intravenous pyelography (IVP) , in which the ultrasonography and computed tomography ( CT) failed to provide accurate diagnosis. Eighteen cases were treated by surgical operations, among them 16 cases were cured, one case lost follow-up, and one case recurred in 6 months after surgery. The data indicate that the diagnosis of pyelogenic cyst mainly depends on IVP examination and the laparoscopic technique can be effectively applied for treatment of pyelogenic cyst.
