Case Report: Posterior Urethral Valves with Severe Unilateral Vesicoureteral Reflux in a 3-year–old Boy
In patients with posterior urethral valves (PUV), severe unilateral vesicoureteral reflux (VUR) is one of the three conditions associated with preservation of renal function. Others are urinary ascites or urinoma in newborns and large congenital bladder diverticula. These conditions most likely provide a pop-off mechanism preventing the development of high intravesical pressure. Only 5% of patients with PUV and an associated popoff
mechanism will develop renal failure as opposed to40 % of patients with PUV without a protective factor. We present a 3-year-old boy with posterior urethral valves and a severe right unilateral vesicoureteral reflux. He had PUV ablation with Mohan’s valvotome and made satisfactory post operative recovery with indication on follow-up of preservation of renal function.
