A giant prostatic urethral calculus has not been previously reported in dogs and should be distinguished from prostatic calculus. A 7-year-old castrated male Maltese dog with a 2-month history of relapsing hematuria and urinary incontinence with slowly progressing paraphimosis was referred. On abdominal radiography and ultrasonography, there was a giant calculus in the region of prostate or urethra, one left ureteral calculus, one urinary bladder calculus, and two penile urethral calculi. On computed tomography for evaluating the accurate location and planning the surgical approach, the giant calculus was located at the prostatic urethra. The calculi in urinary bladder, prostatic and penile urethra were surgically removed. These calculi were mixed-type of calcium oxalate monohydrate, struvite and calcium phosphate carbonate. On the basis of the urolith analysis and urine bacterial culture results, antibiotics and prescription diet were adjusted. At the 3-month follow-up, there were no clinical sings but paraphimosis was still remained, and ultrasonography revealed newly-formed, small urethral calculi at the prostatic urethra. This is the first report to describe the case of a canine giant prostatic urethral calculus and its clinical signs, diagnostic imaging findings, treatment, and outcome. CT may be useful to assess the accurate location and surgical approach for such calculi.

문제 정의
Although the etiology of giant urethral calculus has not been fully investigated, urethral strictures, posterior urethral valves, and urethral diverticula are thought to be associated (1,3,8). This is the first report to describe the case of a giant prostatic urethral calculus in a Maltese dog and its clinical signs, diagnostic imaging, treatment, and outcome.
제안 방법
In order to determine the accurate location of the uroliths and plan the surgical approach, computed tomography (CT) of the abdomen was performed using a 32-row multi-detector CT scanner (Alexion, Toshiba Medical System; Tokyo, Japan). The dog was placed under general anaesthesia using propofol (5 mg/kg, IV, Provive; Myungmoon Pharm Co.
Closure of the surgery site was performed in a routine fashion. The dog was hospitalised for 5 days for postoperative observation and care with a Foley catheter during the first 48 hours. Maintenance fluid therapy with normal saline, as well as cephalexin (22 mg/kg, PO, BID, Falexin; Dongwha Pharm Co.
The dog was hospitalised for 5 days for postoperative observation and care with a Foley catheter during the first 48 hours. Maintenance fluid therapy with normal saline, as well as cephalexin (22 mg/kg, PO, BID, Falexin; Dongwha Pharm Co.), meloxicam (0.1 mg/kg, PO, once daily, Metacam; Boehringer Ingelheim), and famotidine (0.5 mg/kg, PO, twice daily, Hana Famotidine; Hana Pharm Co.) were administered orally for 10 days.
This case report describes the first case of a canine giant prostatic urethral calculus and its clinical signs, characteristics of diagnostic imaging, treatment, and outcome. CT may be useful to assess the accurate location of calculi and plan the surgical approach for dogs with a giant urethral calculus.
