Bilateral congenital midureteral adynamic segments.
Two cases of congenital midureteral adynamic segments are presented. Both children were successfully managed with excision of the lesions and primary reanastomosis. Pathologic examination revealed probe-patent ureters with muscular disarray, suggesting functional obstruction. Appropriate management of the anomaly was dependent on precise radiographic localization of the area of narrowing, and for this retrograde urography was essential. Primary ureteroureterostomy was successful in both cases. In this report we discuss the diagnosis, embryology, radiographic evaluation, and management of this rate situation.
