 A 3-year old boy diagnosed with PUV and bilateral ureter hydronephrosis. He received bilateral ureters reimplantation 2 years before PUV ablation and his left renal function had heavily been damaged. A VCUG highly suspected PUV before operation, left VUR existed. B VCUG showed LUTO and VUR disappeared 3 months after operation. C Urodynamic studies revealed poor bladder compliance along with extremely elevated detrusor pressure when voiding before operation. D Urodynamic studies revealed improved bladder compliance along with decreased detrusor pressure (still higher than the normal) when voiding 3 months after operation. E IVP revealed the presence of right ureter hydronephrosis and no visualization on the left kidney before operation. F IVP revealed clearance of right ureter hydronephrosis and no visualization on the left kidney after operation
