Comparison of Endourological and Open Cystolithotomy in the Management of Bladder Stones in Children

PurposeVesical stones are common in children in developing countries. Cystolithotomy is the traditional treatment but a percutaneous approach has been advocated. The aim of this study was to evaluate retrospectively our experience with percutaneous cystolithotomy, cystolitholapaxy and open cystolithotomy in children with bladder stones.Materials and MethodsA total of 107 children (96 boys and 11 girls) with vesical stones were treated at our center between January 1992 and March 2008. Mean patient age at the time of diagnosis was 5 years (range 2 to 15). The patients were stratified retrospectively into 2 groups according to the procedure of stone removal. Group 1 (53 patients) underwent open cystolithotomy, and group 2 (54) underwent endourological treatment via the transurethral route (27) or the suprapubic approach (27). Stone size ranged from 0.7 to 5 cm (mean 2.8).ResultsIn all cases the stones were removed successfully. Operative time was comparable in both groups. The hospital stay was significantly shorter after endourological procedures compared to open surgery (2.6 vs 4.8 days, p <0.05). In the open surgery group 1 patient had a small intestinal injury that necessitated repair, while in the endourological group 2 patients had urinary extravasation (1 urethral and 1 vesical). There were no early or late complications in group 1. In comparison, 4 patients (7.4%) in group 2 had early complications in the form of persistent urinary leakage from the suprapubic site and 1 patient had a bulbous urethral stricture 1 year after transurethral stone disintegration.ConclusionsOpen and endourological management of vesical stones in children is efficient, with a low incidence of complications. Endourological management offers a shorter hospital stay compared to open surgery. However, open cystolithotomy seems to be safer.
