Summary
Children with unilateral renal agenesis have a higher risk of neurosensory hearing loss, particularly females with genital abnormalities. Early auditory follow-up is recommended for these patients.
Area of Science:
- Pediatric Nephrology
- Otolaryngology
- Genetics
Background:
- Unilateral renal agenesis (URA) is a congenital condition affecting kidney development.
- Auditory abnormalities can occur alongside congenital anomalies.
- The association between URA and hearing impairment requires further investigation.
Purpose of the Study:
- To investigate the link between unilateral renal agenesis and auditory dysfunction.
- To characterize the spectrum of hearing loss in children with URA.
Main Methods:
- Auditory examinations were performed on 75 children with URA.
- A control group of 75 healthy schoolchildren was included for comparison.
- Audiometric testing assessed hearing function, with exclusion of controls with urogenital anomalies.
Main Results:
- Auditory abnormalities were more prevalent in children with URA (5.3%) compared to controls (0%).
- Four children with URA exhibited ipsilateral sensorineural hearing impairment, predominantly high-frequency.
- All affected children were female with coexisting genital abnormalities, experiencing mild to moderate hearing loss.
Conclusions:
- Neurosensory hearing loss is associated with unilateral renal agenesis.
- Children with URA, especially females with genital anomalies, warrant audiometric follow-up.
- Further research into the underlying mechanisms is suggested.
