The Outcome of Posterior Urethral Valves among Children in Tertiary Care Hospital–A Prospective Study

Abstract

Introduction: Posterior Urethral Valve (PUV) is the most common cause of lower urinary tract obstruction in male children. This obstruction in posterior urethra could lead to severe dilatation of upper urinary tract and functional impairment of one or both kidney. The presentations are not always same for all patients. Early diagnosis and appropriate treatment may reduce the progressive damage and helps in recovery. Aim of the Study: The aim of this study was to find out the presentation and to assess the short term functional outcome after fulgaration of the patients with PUV. Methods: This prospective study was conducted at Pediatric urology department, Bangladesh Shishu Hospital and Institute, Dhaka. We included fifty patients with Posterior urethral valve, who were treated at the pediatric urology department from Jan, 2019 to Nov, 2021. Result: Total 50 patients enrolled in the study. In our study we found 50% of our patients were aged between 1 month to 1 year, followed by 36% were more than 1 years old and 14% were less than 1 month old. 76% patients were presented with dribbling of urine. 40%,26%,10% and 6% patients had UTI, poor stream,, retention of urine and palpable bladder respectively. 45 patients had bilateral hydronephrosis ( HDN) at presentation and only 5 had unilateral hydronephrosis in USG. At follow up MCU, 14% patients had unilateral VUR and 10% patients had bilateral VUR. Mean postoperative serum creatinine was 0.585 mg/dl. We found residual Valve in 11(22%) patients during follow up who required repeat Valve ablation. Conclusion: In our study, we found that Cystoscopic valve ablation and follow up is the treatment of choice for PUV patients which may arrest the progressive damage of renal function and facilitate the improvement. Further multicenter study and long term follow up is necessary for understanding the ultimate outcome.
