Traumatic strictures of the prostatomembranous urethra in children: radiologic evaluation before and after urethral reconstruction.
Impassible strictures of the posterior urethra are frequent sequelae of injuries of the prostatomembranous urethra. To select the appropriate type of urethral reconstructive procedure, the surgeon must know the length of the stricture, whether local complications are present, and whether the anterior urethra is strictured or bound down by fibrosis. The authors describe the radiographic techniques they use to plan urethral reconstruction and evaluate the operative result. The principles of the one-stage transperineal and combined transpubic-transperineal repairs and the two-stage Turner-Warwick scrotal skin inlay urethroplasty are presented to enable radiologists and urologists to interpret contrast studies of the lower urinary tract in patients who have undergone these operation.
