TWO CASES OF CONGENITAL URETHRAL VALVE

Abstract

Two cases of congenital urethral valve were experineced. One was a four-year-old boy with congenital anterior urethral valve, who was treated with transurethral resection of the valve.
After the operation, normal voiding was established. Histological examination of the valve revealed smooth muscle and connective tissue proliferation.
The other case was a seventeen-year-old boy with congenital anterior urethral stricutre and posterior urethral valve. Since marked hydronephrosis and decreased renal function were seen in both kidneys, conservative neprhostomy was chosen. On account of this valve and stricture, his urinary stream was weak. These two cases indicate that the formation of the anterior urethral valve is necessary for the power of urinary stream.
