Answer:
Abstract two primaries for this scenario per Rule M7. The first primary is the renal pelvis in Oct. 2006; the second primary is the ureter in Nov. 2009. The bladder tumor in July 2008 is not a new primary per Rule M8.
Compare the diagnosis date of the current (most recent) tumor to the diagnosis date of the original tumor. This applies even if the patient had six occurrences in-between these dates; you still compare the current tumor to the diagnosis date of the original tumor and ignore recurrences in this process.
