Determining the cause of a male reproductive discharge is directed first by the nature of the discharge—but then what? Use this algorithm to resolve these cases.

How to Perform Prostatic Wash

1. Allow the patient to urinate
2. Sedate the patient
3. Empty the dog’s bladder via catheter and flush with 5–10 mL of saline. Save sample for urine cytology and culture.
4. Pass a polypropylene or red rubber catheter over the pelvis rim. With a digit in the rectum, position the tip of the catheter just caudal to the prostate
5. Vigorously massage the prostate per rectum with the inserted digit
6. Occlude the urethral opening and inject 5–10 mL sterile saline
7. Advance the catheter forward a few centimeters while aspirating as much sample as possible
8. Perform cytology and culture on the recovered sample and compare to urine sample.
