【 摘 要 】

Background

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary renal disorder. In most cases, ADPKD similarly affects bilateral kidneys.

Case presentation

Among the 605 ADPKD patients that were followed up by our center, we identified two male patients with unilateral ADPKD. The cases were remarkable because the patients also had ectopia and multicystic dysplasia in the contralateral kidney, which are generally sporadic disease conditions. Both patients tested positive for polycystic kidney disease 1 mutation, but negative for hepatocyte nuclear factor 1 beta mutation. Moreover, the deterioration of their kidney function seemed to be quicker than their age- and sex-matched controls and siblings. Both patients had started a long-term hemodialysis in their 40s.

Conclusion

Anatomical and genetic abnormality in patients with ADPKD may be more frequent and complex than previously believed. The compensatory capacity in patients with ADPKD is fragile, and missing one kidney could accelerate the deterioration of renal function.
