Conclusion

The first patient had cystic changes of the rete testis. Cystic dysplasia of the testis is often associated with  abnormalities of the kidney on the same side In this case the kidneys were normal and the cysts reversible. The second boy had an agenesis of the left testis and the left kidney.
