Clinical report in treating children with concomitant anterior and posterior urethral valves

Objective To investigate the approach to reduce diagnostic error of concomitant anterior and posterior urethral valves. Methods The clinical data of 3 patients was retrospective analyzed, who was with concomitant anterior and posterior urethral valves admitted from January 2010 to October 2015.The literatures of the similar cases were reviewed. The 3 patients were all male, and the average age was 5 months (3 - 7 months) at diagnosis. The patients with remaining obstructive symptoms after the release of the posterior urethral valves underwent VCUG, cystoscope, and further surgical treatment for anterior urethral valves. Results Posterior urethral valves were found in all the 3 patients at diagnosis and were fulgurated. However, clinical symptom improvement was not obvious. Anterior urethral valves were indicated by VCUG and then fulgurated in all 3 patients. Thereafter, all clinical symptoms were improved significantly. Conclusions It was necessary to reexamine by VCUG, urodynamics, and cystoscope in the patients without obvious improvement after fulguration of posterior urethral valves, in order to avoid diagnostic error of concomitant anterior and posterior urethral valves.
