Abstract:
Urethral polyps are rare benign lesions causing urinary tract obstruction in pediatric patients, predominantly affecting males. They arise from the posterior urethra in males and mid-urethra in females. An 11-day-old male with antenatal hydronephrosis presented with UTI. Imaging revealed bilateral grade II hydronephrosis, distended bladder, and grade 5 bilateral vesicoureteral reflux. A fibroepithelial urethral polyp was identified and treated with bipolar resection. Postoperative evaluation showed complete resolution of symptoms, emphasizing the importance of comprehensive urological evaluation in neonates with antenatal hydronephrosis.
