A seven year old intact male Rottweiler presented to the CUHA Internal Medicine Service on 2/19/14 for intermittent hematuria that had started in August 2013. The referring veterinarian prescribed Enrofloxacin in August which appeared to provide resolution but the hematuria then returned in December 2013. Subsequent courses of antibiotics were ineffective. A urinalysis, urine culture, and bladder ultrasound performed in January 2014 by the referring veterinarian revealed a specific gravity of 1.016 with the presence of blood, bilirubin, and protein. No bacterial growth was cultured and the ultrasound was positive for an enlarged prostate. On presentation at the CUHA in February 2014 the patient's general physical exam was normal. His abdomen palpated as tense but otherwise normal. On rectal exam the prostate was not palpable. The prepuce and penis were unremarkable and the urine he dribbled in the exam room appeared grossly normal with no blood present. His testicles were of normal size and shape and palpated normally and were non-painful. The patient was discharged at this time with a presumptive diagnosis of benign prostatic hyperplasia and a recommendation of further diagnostics and castration. The patient was castrated by the referring veterinarian on 4/15/14. Following this surgery the owner noted the patient was incontinent and the urine was brown-tinged. He was seen by the referring veterinarian on 5/12/14 and treated with trimethoprim/sulfamethoxazo/e which returned the color of the urine to normal but did not alleviate the incontinence. On presentation at the CUHA on 5/23/14 an abdominal ultrasound performed at this time revealed a large round cyst like structure similar to the bladder found adjacent to the bladder and prostate. The patient returned to the CUHA's Soft Tissue Surgery Service on 6/17 /14 and the paraprostatic cyst was successfully drained and removed with a subsequent resolution of his incontinence.
