摘要: A 2-year-old, 45 kg, Shami buck was referred to the Veterinary Health Center (VHC) at Jordan University of Science and Technology with a 2-month history phimosis. The owner reported that, initially, there bilateral symmetrical, soft, fluctuating swelling, cranial scrotum. treated antibiotics anti-inflammatory drugs. swelling had become smaller harder over time, but it not resolved. On presentation VHC, alert normal heart rate (90 beats/min), rectal temperature (38.7°C), respiratory (34 breaths/min). placed in lateral recumbency penis partially extruded. large asymmetrical approximately 10 cm × 4 diameter, could be felt distal end sigmoid flexure (Figure 1). Longitudinal cross-sectional ultrasonographical imaging, using 5 MHz linear array transducer, depicted homogenized hyperechoic mass small anechoic spots surrounded by capsule 2). Based on history, clinical signs, findings, penile hematoma suspected surgical exploration area recommended owner. Figure 1 The is recumbency; represents hematoma. Figure 2 A sonographic image hematoma. Notice margins cavity mixed echogenicity lumen. Preoperative antibiotics, procaine penicillin, 20 000 IU/kg bodyweight (BW), streptomycin sulfate, mg/kg BW, (Pen-Strep; Norbrook, Newry, Ireland), IM, flunixin meglumine, 1 (Finadyne; Schering Plough, Levallois-Perret, France), IV, were administered. Presurgical sedation achieved administering xylazine hydrochloride (Rompon; Bayer, Leverkusen, Germany), 0.05 IV. The positioned dorsal aseptically prepared from base scrotum external preputial orifice. Lidocaine 1% infiltrated locally anesthetize site. An elliptical skin incision, 10–12 length, made directly subcutaneous peripenile connective tissues dissected bluntly expose penis. originated aspect bend flexure, opposite attachment retractor muscle. blood clot evacuated flushed diluted betadine solution. 3 cm- 5-cm rent tunica albuginea repaired size 0 absorbable suture material bootlace pattern, replaced its position. Then elastic penis, tissues, sutured separately. Antibiotic nonsteroidal drugs administered for d. The instructed separate females rest him least 60 d any sexual activity. Two weeks after surgery, decreased significantly exteriorized fully. Six months that returned service without complications. The cause this determined. Perusal available databases references failed find reports ruminants, information textbooks usually extrapolated data bulls. The etiology ruminants unknown, likely similar bulls. Penile or ruptured broken common injury beef dairy bulls (1–4), seen mostly an unsuccessful attempt mating. In bulls, erection classified as low-volume, high-pressure type erection. Peak pressure corpus cavernosum fibrocartilaginous may rise up 14 mm Hg (1,5,6). As bull tries breed, failure intromission leads erected being bent ventrally ruptured. Rupture breaks closed system covernosum escapes. Subsequent attempts mate increased flow result further accumulation (1). The bucks also mechanism seems (2,3). Although traumatic injuries are uncommon due fighting, report running freely females, so logical conclude case breeding injury. Failure return treatment appears related both nonsurgical complications, including abscess formation, recurrence next season, fibrous tissue adhesion formation between layers skin, glans analgesia direct trauma nerve impinging during healing, finally vascular shunts vessels (1,8–10). No complications noted following surgery buck. fully 2 wk season. Since long-term complication, hand mating suggested doe estrus avoid occurrence attempts.
