What are 4 types of peritransplant fluid collections?

These commonly develop 1-2 weeks after transplant, and have a anechoic appearance that will increase in size

These are the most common fluid collection that cause hydronephrosis, are a anechoic mass located medial to TX, and frequently contain septations

These take a few weeks to develop after surgery, and require drainage, and appear as irregular complex systic masses
