“…Posterior urethral valves (PUVs) have an incidence rate of approximately 1/5000 to 1/8000 among male neonates, [1] while anterior urethral valves (AUVs) are less common than PUVs, with an incidence rate of approximately 1/15 to 1/30 relative to that of PUVs. [2] Because it constitutes an extremely rare congenital urologic anomaly, the clinical understanding of concomitant PUVs and AUVs has remained poor. [3] The mechanism of concomitant PUVs and AUVs is unclear, and is presumably similar to that of PUVs, with respect to gene mutations.…”

Background: Concomitant anterior urethral valves (AUVs) and posterior urethral valves (PUVs) is an extremely rare congenital urologic anomaly, which may be easily overlooked in the clinic. Objective: This study assessed the prognosis of children with concomitant PUVs and AUVs. Methods: The clinical data of inpatients with concomitant AUVs and PUVs in our hospital were collected from January 1983 to June 2022. The clinical manifestations, auxiliary inspection, and treatment were described in detail. Results: In total, 6 cases of concomitant AUVs and PUVs in boys were found in our hospital, with ages ranging from 3 months to 9 years; the main clinical manifestation was abnormal urination. Four patients exhibited concomitant AUVs and PUVs preoperatively and underwent simultaneous anterior and posterior urethral valvotomy. Follow-up studies showed that 3 patients’ clinical symptoms substantially improved with well-maintained renal function. One patient died of renal failure. In the other 2 patients, PUVs were initially identified and excised, but their clinical symptoms did not show substantial improvement. Following voiding cystourethrography (VCUG), the AUVs were found and obstructions were then completely relieved. However, 2 patients died of renal failure. Conclusions: If urinary symptoms cannot be substantially relieved after posterior urethral valvotomy, VCUG and cystoscopy should be repeated to shorten the interval between anterior and posterior urethral valvotomies to improve patient prognosis.
