[Percutaneous nephrolithotomy (PCNL) in a 9-year-old patient with horseshoe kidney].

INTRODUCTION: The horseshoe kidney is the most frequent renal anomaly, with a prevalence of 0.25% and a male to female ratio of 3:1. Although the pathogenesis remains controversial, the consequences of the impaired urinary drainage are well known: up to two third of patients present with urinary stasis, infection and urolithiasis. Percutaneous nephrolithotomy (PCNL) is a successful procedure for urolithiasis in horseshoe kidneys.

MATERIALS AND METHODS: A 9-year-old patient with a 4-cm stone associated with horseshoe kidney underwent Percutaneous nephrolithotomy (PCNL). During the procedure, a flexible uretheroscopy was performed in order to obtain a complete vision and an optimal management of the procedure.

RESULTS: At the end of the procedure, the patient was stone-free. We reported no hemorrhagic complications, no pain and no infection. The patient was discharged after 48 hours.

CONCLUSIONS: The procedure is safe and effective, as long as the surgeon pays attention to the recommendations below.
