Inclusion criteria

Inclusion criteria: Patients with ADPKD and ARPKD are diagnosed according to the Japanese PKD guideline criteria, or genetic information. For the ADPKD cohort, patients with an eGFR more than 15.0 will be included.

Exclusion criteria

Exclusion criteria: Exclusion criteria include: history of kidney transplantation, active cancer, cancer treatment within last 5 years, or participation in a PKD-related clinical trial. If pathological or genetic examinations reveal that a patient has a type of PKD other than ADPKD or ARPKD, they will be excluded from the study, even if they have already enrolled.

Design outcomes
