Overview
Renal caliceal diverticuli-deafness syndrome is an extremely rare genetic condition that combines kidney abnormalities with hearing loss. The kidney problem involves caliceal diverticula, which are small pouch-like outgrowths from the calyces — the cup-shaped structures inside the kidney that collect urine before it flows into the ureter. These pouches can trap urine and sometimes lead to kidney stones, urinary tract infections, or other complications. The hearing loss in this syndrome is sensorineural, meaning it results from problems in the inner ear or the nerve pathways that carry sound signals to the brain. This type of hearing loss can range from mild to severe and may affect one or both ears. Because this syndrome is so rare, very few cases have been described in the medical literature. The exact genetic cause has not been fully identified, and treatment is mainly focused on managing symptoms. Hearing aids or cochlear implants may help with hearing loss, while kidney complications such as stones or infections are treated as they arise. Monitoring kidney function over time is important. Patients benefit from a team of specialists including kidney doctors and hearing specialists who work together to provide coordinated care. Research into this condition is limited, and much remains to be learned about its long-term outlook and underlying genetic mechanisms.

How is Renal caliceal diverticuli-deafness syndrome inherited?
Renal caliceal diverticuli-deafness syndrome follows a autosomal dominant inheritance pattern. Genetic counseling can help families understand recurrence risk and testing options.
At what age does Renal caliceal diverticuli-deafness syndrome typically begin?
Typical onset of Renal caliceal diverticuli-deafness syndrome is childhood. Age of onset can vary across affected individuals.
