BACKGROUND: This study aims to elucidate the clinical characteristics, management, and prognosis of anterior urethral valves (AUV) in children.
METHODS: A retrospective analysis was performed on 8 pediatric AUV patients (2015-2025), examining their clinical presentation, imaging and renal function data, surgical management, and reoperation rates. Prognosis was evaluated during follow-up.
RESULTS: Among the eight patients, four were diagnosed with AUV (one including posterior urethral valves (PUV)), and four had AUV combined with diverticula (one also associated with PUV). All diagnoses were confirmed by retrograde cystography and/or cystoscopy. Associated findings included bladder trabeculation in four cases and vesicoureteral reflux in four. Three patients had renal impairment. Treatment included cystoscopic electrocoagulation of the urethral valves, or a combination of valve resection, diverticulectomy, and urethral reconstruction. Postoperatively, five patients recovered completely, while one experienced occasional urinary tract infections (UTI). Two patients required reoperation; they continue to exhibit vesicoureteral reflux and renal impairment, and remain under close observation.
CONCLUSION: AUV can be definitively diagnosed via cystoscopy or voiding cystourethrogram (VCUG). Surgical intervention, including endoscopic valve ablation or open urethroplasty, yields favorable outcomes. However, the prognosis for patients with pre-existing renal impairment remains poor. Consequently, close monitoring and long-term follow-up are imperative.
