Multicystic Kidney: is there any new scientific evidence to recommend nephrectomy?]

With the aim to create a scientific evidence of the convenience or not of removing the Multicystic Kidney (MK), a systematic review has been done over the last 20 years, selecting those articles with determinant criterions. Our experience has been also evaluated. We have obtained an evidence table of 1082 MK, with a follow-up from 2 to 7 years. No case degenerated. The complications were: urinary tract infection (UTI) in 5% and hipertensión (HTA) in 0.7%. In our serie (68 cases): nephrectomy was done in 10 cases. 82% completely involved (66.6% before 5 years and 15.6% from 5 to 15 years of follow-up). 18% involved partially. No case degenerated. The complications were UTI (6 cases) and HTA in one. Periodical ultrasound follow-up is our recommendation for MK due to the results of our serie and from the systematic review of the literature.
