Gülhane Military Medical Academy, Dept. of Urology, Ankara, Turkey INTRODUCTION & OBJECTIVES: Type 3 PUV is extremely rare congenital anomaly which can lead to irreversible bladder and kidney damage with infravesical obstruction. In this case, we aimed to share our surgical experience in a case of type 3 PUV ablation therapy with Holmium YAG laser in child. MATERIAL & METHODS: 8 years old male patient followed up antenatal hydronephrosis during neonatal period and as a result of hydronephrosis vesicostomy opened and vesicostomy was closed when 2 years old after PUV ablation. Bilateral thinking of renal parenchycma in ultrasonography. The patient was referred to us with complaints of chronic renal failure and incontinence. Patient under went VCUG and in VCUG, bladder wall irregularity was observed but VUR wasn't detected (Figure 1).

Figure 1 RESULTS: Cystoscopy was performed to patient and type 3 PUV was detected (Figure 2). PUV ablation was performed with Holmium YAG laser to opened the urethral lumen (Figure 3).

Figure 2 Figure 3 CONCLUSIONS: The endoscopic transurethral Holmium YAG laser ablation treatment in PUV is simple, feasible, safe and effective treatment option. Compared with other endoscopic treatments have similar success rates and low complication rates. Eur Urol Suppl 2015; 14(8): e1422
