Description
Shunya Takada and co-authors report a rare case from 2026 in which a baby boy was born with a doubled urine channel and a malformed anus and rectum. The infant also had several other birth defects, and passing urine was hard from the start. Scans and dye tests showed two channels where one should be, plus a pouch that formed after early surgery.
Care came in stages rather than one large operation. Surgeons first repaired the bowel, then used a thin scope, a balloon, and a laser to widen the narrow channel and remove the pouch. By twenty-one months the child could pass urine on his own, and his kidneys still worked well at the last check.
