A 2-month-old girl is brought to the pediatric clinic due to persistent irritability, poor feeding, and failure to gain weight. Her parents also note that her abdomen appears somewhat swollen, and she has been urinating less frequently than expected. The parents mention that she was born at term with an unremarkable pregnancy but had a history of urinary tract infections shortly after birth.

On examination, the baby is fussy and has a mildly distended abdomen. Her weight gain is below the expected curve for her age. A palpable bladder is noted in the lower abdomen. Further investigations, including an abdominal ultrasound, reveal a small, underdeveloped bladder and mild hydronephrosis of the kidneys, consistent with vesical hypoplasia, a condition where the bladder does not develop fully.

The baby is referred to a pediatric urologist for further evaluation. A management plan, including possible surgical interventions, is discussed, and the parents are educated on the condition. The baby is closely monitored for renal function and urinary tract infections, and a follow-up plan is established for ongoing care.
