Abstract

Introduction: In the last years due to miniaturization of endoscopic instruments and percutaneous surgery, endourology has become very popular in paediatric urinary stone managment. We reported our single-centre experience in retrograde endoscopic procedures in children. Results and complications of URS/RIRS are discussed.
Materials and methods: We retrospectively reviewed our experience in patients ≤ 16 years old affected by urinary stones who underwent URS/RIRS procedures performed by two surgeons with expertise in endourology. A total of 30 renal Units (RUs) underwent endoscopic procedures (URS, RIRS or both). Surgical complications according to the ClavienDindo’s classification and stone-free rate were evaluated at 3 months follow-up. Success of URS was defined as stone-free status after single procedure while RIRS success rate was considered as presence of residual stone fragments smaller than 4 mm at first procedure.
Results: The mean age of our patients was 8 years, range 2- 16 years. A total of 30 renal units (RUs) underwent 40 endourological procedures (23 URS and 17 RIRS; 10 children underwent both procedures at the same time). 17/30 (56.6%) RUs were pre-stented before surgery. The stone-free status was achieved in 23/30 renal units treated, with a 76.6% success rate. The remaining 7 patients had residual stones greater than 4 mm and underwent further treatments. After a second surgery the stone-free rate turned out to be 93.3% (28/30 renal units).
Conclusions: Rigid and flexible ureteroscopy (URS/RIRS) is a reliable technique for treatment of < 2 cm urinary stones in paediatric age group. It shows low rate of major complications and promising results in terms of stone-free rate.
