203 11–14 APRIL, 2018, HELSINKI, FINLAND RESULTS Pre-operative dorsal/ventral shaft length asymmetry is effectively corrected by this technique. Likewise, better phallic exposure is achieved. Patients tolerate the procedure well without complications. CONCLUSIONS These additional modifications to our approach for correcting penile concealment enhance creation of a normal penopubic junction and achieve a cicatrix-free shaft. This technique is easily performed and should be considered when performing circumcision in the face of penile concealment. VD-11 (VS without presentation) MICROURETEROSCOPY FOR CORALLIFORM LITHIASIS IN CHILDREN Alberto PARENTE  1 , Laura BURGOS  2 , Ruben ORTIZ  2 and Jose Maria ANGULO  2 1) GREGORIO MARAÑÓN UNIVERSITY HOSPITAL, PEDIATRIC UROLOGY, Madrid, SPAIN - 2) Gregorio Marañon University Hospital, Pediatric Urology, Madrid, SPAIN PURPOSE Miniaturization of the equipment for percutaneous renal surgery also allows its use for retrograde treatment of ureteral lithiasis, reducing pain, risk of ureteral damage, and the need of catheters after the operation. The MicroPerc 4.8F sheath has been used to diagnose and treat ureteral pathologies in children. We present its use for the treatment of coralliform lithiasis in children. MATERIAL AND METHODS A 2-year-old girl was referred to our centre because of a right coralliform lithiasis. As background, she presented repetitive UTIs. MicroPerc set 4.85F sheath was used to perform nephroureteros- copy, thus avoiding the need to dilate the ureteral meatus. Lithotripsy was performed successfully. RESULTS Surgical time was 92 minutes. The patient was discharged within the next 24 hours. There were no complications. Ultrasound performed at 8 weeks showed residual lithiasis less than 2 mm. CONCLUSIONS The use of microureteroscopy proved satisfactory in children. It allows diagnosis and treatment of large kidney stones in pediatric patients.
