    Abstract:
    Posterior urethral valves are the most common cause of congenital obstructive uropathy leading to renal failure in childhood. This study was undertaken to assess the outcome of endoscopic fulguration of posterior urethral valves based upon the clinical, radiological and laboratory findings. This prospective study was carried out on 50 male children with posterior urethral valves who were treated by endoscopic fulguration and came for routine follow-up. Diagnosis of posterior urethral valves (PUV) was confirmed by voiding cystourethrogram (VCUG). After valve ablation, urine R/M/E, urine for culture and sensitivity test, serum creatinine level, USG of KUB including PVR were done in all cases at 1,3,6,12 months and then at six months interval maximum up to 3 years. Mean age of the patients was 2 years ranging from 1 to 12 years old. Mean follow-up period was 30.48 months after valve ablation. At diagnosis mean serum creatinine +/-SD was 90.4+/-44.8 mumol/lit and it decreased to 56.3+/-11.1micromol/lit at the end of 3-years follow-up. Hydronephrotic changes decreased from 84% to 4%. Proteinuria decreased from 38% to 6% and urinary tract infections decreased from 58% to 4% at the end of final follow up. Although the techniques for posterior urethral valves ablation have been refined and the short-term management of patients with posterior urethral valves has improved remarkably, there is growing concern about the long-term outcome. At present endoscopic fulguration with observation is the treatment of choice for posterior urethral valves. In this study patients improved dramatically following fulguration of posterior urethral valves. Early diagnosis and appropriate therapy may arrest progressive damage and facilitate recovery. Further follow-up studies of longer duration are needed.
