Synonym(s): Prostate wash; Prostate massage

Contributor(s): Andrew Gardiner

Introduction

  • To obtain a sample of prostatic fluid for culture and/or cytological evaluation using the urinary catheter method.
  • This usually entails comparing the prostatic fluid sample to both a urine sample and a urethral swab, in an attempt to minimize the confusing effect of urine and urethral bacterial contamination on the prostatic fluid sample.
  • If higher numbers of bacteria are present in the post-prostatic massage sample, then a prostatic infection is likely.
  • Neoplastic cells may also be retrieved from the post-massage sample.

Uses

  • → In the investigation of prostatic diseases, especially infection and neoplasia.

Advantages

  • Relatively cheap and easy to perform.

Disadvantages

  • Problems can arise due to bacterial contamination from (a) the bladder and (b) the urethra, such that there can be uncertainty as to the significance of culture results. These problems are minimized, but not removed entirely, by good technique and by obtaining samples from these areas prior to collecting the prostatic fluid.
  • Prostatic massage can be difficult to perform in large breed dogs with an anteriorly situated prostate.
