Patient Data

Age: 5 months
Gender: Male

There is partially distended, thick-walled urinary bladder with bilateral moderate hydroureter and hydronephrosis. There is a right perinephric anechoic collection which associated with upper pole calyceal fornix rupture. Moderate ascites is present in the abdomen. The posterior urethra is dilated. There is a presence of an echogenic linear structure in the posterior urethra at the junction of the distended and collapsed urethra.

Case Discussion

An infant presented with excessive crying and abdominal distension for the last few days. Ultrasound shows a posterior urethral valve. There is a rupture of a right renal upper pole calyceal fornix with right perinephric urinoma. The presence of the ascites is possibly due to intraperitoneal rupture of the urinary bladder. However, it could not be confirmed during the scan.
