Laparoscopic diverticulectomy and ureteric reimplantation for congenital bladder diverticulum

Congenital bladder diverticula are rare anomalies that may be associated with vesicoureteric reflux, ureteric ectopia, and impaired bladder emptying. We report a male infant initially found to have distal ureteric dilatation on postnatal ultrasonography. Micturating cystourethrogram demonstrated a contrast-filled structure adjacent to the bladder, raising suspicion of distal ureteric dilatation or bladder diverticulum. Serial imaging confirmed persistence of the lesion. By 3 years of age, the patient developed recurrent urosepsis and voiding dysfunction. Further assessment demonstrated a large bladder diverticulum with ureteric insertion. The patient underwent cystoscopy and laparoscopic diverticulectomy with ureteric reimplantation. Intraoperative findings confirmed a large diverticulum with ureteric insertion into its mid-portion. Reconstruction was achieved without complication, with resolution of symptoms and improved bladder emptying at 3 months follow-up. This case highlights the diagnostic challenges of distal ureteric dilatation and demonstrates the role of minimally invasive surgery in managing complex lower urinary tract anomalies.
