Allantoic cysts and posterior urethral valves: a case report

Allantoic cysts and posterior urethral valves: a case report.

Allantoic cysts are a somewhat rare entity. They are identifiable on antenatal ultrasound examination but are not easily distinguishable from pseudocysts, which are often associated with a poor prognosis. Their etiology remains obscure and obstructive uropathies have been proposed to be one of the underlying mechanisms. We report on a case in which both allantoic cysts and a patent urachus were...

Posterior Urethral Valves

Posterior Urethral Valves

The most common cause of lower urinary tract obstruction in male infants is posterior urethral valves. Although the incidence has remained stable, the neonatal mortality for this disorder has improved due to early diagnosis and intensive neonatal care, thanks in part to the widespread use of prenatal ultrasound evaluations. In fact, the most common reason for the diagnosis of posterior urethral...

Anterior urethral valves. A case report.

Anterior urethral valves are rare anomalies which cause obstructive uropathy in the lower urinary tract of young men. We discuss our illustrative case and review the English medical literature in order to analyze the clinicopathologic spectrum. We propose a hypothesis of embryology of this lesion and present guidelines for its management.

A case of hypospadias, anterior and posterior urethral valves

This report outlines the case of a 3-year-old boy whose initial presentation was that of asymptomatic hypertension (lowest recording 148/90), found at preoperative check prior to stage 2-correction surgery for distal hypospadias. Upon diagnosis of true hypertension, an ultrasound of the child's renal tract showed evidence of marked hydronephrosis and calyceal dilatation. On the background of de...
