Review of Kidney Biopsies of Dent Disease Patients

Systematic Review of Clinical Biopsies of Dent Disease Patients

This study is being done to obtain pathology reports from all patients in the Dent disease registry who have had a kidney biopsy. The investigator will collect the biopsy slides and reports in an attempt to determine if they have any common findings.

If the patient agrees to be in the study, the patient will be asked to participate in the following:

• Sign a consent form indicating the patient's willingness to participate.
• Provide a signed medical release form allowing the investigator to request your official kidney biopsy reports, and also allowing the investigator to request the original slides for review. At the end of the study, all slides will be returned to the referring facility.
• The investigator will also review your medical record

Inclusion Criteria:

• All patients in the Dent Disease Registry with a previous renal biopsy.

Exclusion Criteria:

• None.
