Description
Masaki Shinohara is first author on a 2026 case report of kidney surgery in a child with OHVIRA syndrome. OHVIRA is a rare birth condition. It combines a blocked half-vagina with a kidney anomaly on the same side. Some variant cases have a tiny, poorly formed kidney draining into the vagina, causing constant urine leakage, so removing the kidney is required.
At age five, doctors found the misplaced urine tube opening by vaginal scope and threaded a fluorescent catheter, a glowing tube, backward through it. During keyhole surgery, the glow reliably showed the tube and the small kidney remnant, guiding safe removal. The authors present the technique as feasible and useful for selected children with this condition.
