Inc. The most common developmental abnormality of the puppy bladder is a persistent urachus. This tube allows fetal urine to exit the fetus and be absorbed into the mother's system for elimination from her body. At the time of birth the urachus should be closed and non-functional. If the urachus fully persists and is open then urine will leak from the newborn's navel area. Bacteria frequently invade this diverticulum from inside the bladder causing repeated bladder infections and painful urination.
Risks vary depending on the extent of abnormality and the associated urinary infections.
All cases are potentially serious if left untreated. Surgery to remove the tube or diverticulum from the bladder surface is required if a cure is to be expected. Antibiotics will help treat any associated infections. Inc. All rights reserved.
