Transurethral prostate biopsy

Hi all,
I have an op report generating some confusion for me...

I then switched to the 25-French resectoscope. The urethral meatus was sounded using Van Buren sounds to 28 French. A 25-French resectoscope was then inserted. Swipes were taken from the lateral lobes as well as the posterior aspect of the prostate.

The doctor was performing biopsies of the bladder and both renal pelvis' via washing and samples of bladder wall tissue. For the paragraph above the dr coded 52601-52. I'm sure this is incorrect, however, I cannot find a code that accounts for this biopsy.
Can anyone help?

Thank you
Jennifer
