The surgeon could not find the collection. Using a tandem approach, a 6.7 Fr McGahan catheter was advanced and coiled in the lymphocoele cavity. After 24 hours of drainage, the lymphocoele cavity was filled with methylene blue, allowing the surgeon to easily identify the collection at laparoscopy. While most are small and do not require additional therapy, haematomas may occasionally compress the ureter and produce hydronephrosis. An AVF occurs as a consequence of simultaneous laceration of a renal artery branch and an adjacent vein during biopsy.
Observation is generally all that is necessary as most spontaneously thrombose.
