In children with full bladders verified by ultrasound, complications are rare. Small amounts of blood in the urine after the procedure is common and resolves quickly. Large amounts of blood in the urine or infection of the abdominal wall puncture site are rare. Puncture of the bowel with the needle can occur if a loop of intestine overlays the bladder, but peritonitis is rare with such a small puncture. This can be avoided with use of ultrasound.
