Neonatal bladder rupture is rare as a complication of bladder obstruction due to abnormal anatomy or iatrogenic cause such as umbilical catheterization. The present study describes the case of a 27-day old infant with ascites due to bladder perforation secondary to bladder wall necrosis as a result of severe urinary tract infection. The baby was treated aggressively with antibiotics and underwent successful surgical repair of the perforation.
