Urethral duplication with bilateral megaureter and bladder outlet obstruction: unusual case managed by PADUA technique.

Abstract

Urethral duplication is a rare congenital anomaly of the lower urinary tract. The most used classification system was suggested by Effmann [1] in 1976, based on radiological findings. The duplication most commonly occurs in the sagittal plane with one urethra located ventrally and the other dorsally [2]. Treatment depends on the type of duplication and comorbidities [3]. We describe an unusual presentation of complete hypoplastic type 2A-2 urethral duplication according to Effmann with bilateral obstructive megaureter and prolonged bladder outlet obstruction, which was managed through Progressive Augmentation by Dilating the Urethra Anterior (PADUA).
