RESUMEN
Although accurate diagnosis of seminal vesiculitis still seems to be a problem, the disease can be treated surgically if the value of the animal warrants. Although this technique offers superior surgical exposure and seems to be successful in young bulls, its value in adult bulls is still questionable. There have been no reports of successful seminal vesiculectomy in aged bulls of which the authors are aware.

CASE DESCRIPTION: An 11-year-old 72-kg (158-lb) sexually intact female alpaca was examined for diagnosis and treatment of hematuria of 4 months' duration. CLINICAL FINDINGS: Pigmenturia was detected by the owner when the alpaca was 8 months pregnant. Radiographic, ultrasonographic, vaginal speculum, and cystoscopic evaluation of the urinary tract revealed normal vaginal and urethral epithelia and increased bladder vessel tortuosity, with pulses of hemorrhage from the left ureter. Regenerative anemia and mild leukopenia were detected and serum urea nitrogen and creatinine concentrations were within reference ranges. TREATMENT AND OUTCOME: Chronic hematuria resolved after unilateral nephrectomy of the left kidney, and no dysfunction was detected in the remaining kidney. Histologic evaluation of the kidney revealed a transitional cell tumor in the renal pelvis. CLINICAL RELEVANCE: Although anemia is common in South American camelids, hematuria is an uncommon sign of this condition. Chronic urinary tract infection, toxin ingestion, and neoplasia causing hematuria or hemoglobinuria should be considered in South American camelids with pigmenturia. Thorough and systematic evaluation of the urinary tract should be performed to locate the site of hemorrhage to treat hematuria appropriately.

OBJECTIVE: To document signalment, clinical signs, and long-term outcome of surgical treatment for femoral capital physeal fractures in cattle. STUDY DESIGN: Retrospective study. Animals-Twelve cattle with femoral capital physeal fractures. METHODS: Cases were identified by a search of radiographic records. Historical, diagnostic, surgical, and outcome data were collected from the medical records. Owners were contacted for follow-up information by telephone. RESULTS: Fractures were repaired by screws inserted in lag fashion in 4 animals and by use of multiple intramedullary pins in 8 animals. Six of 12 animals required repeat surgery to reposition screws or pins. Nine animals were considered successfully treated at discharge. Six months after surgery, 6 of 11 animals for which follow-up was obtained were still sound. At 12 months, 4 of 4 animals alive were still sound. Animals that bore weight earliest postoperatively were more likely to have a successful outcome. Animals <12 months of age had better outcomes than animals >12 months of age. CONCLUSIONS: Prognosis for serviceable soundness is good in cattle <12 months of age and fair in animals >12 months of age after surgical repair of femoral capital physeal fracture by stacking intramedullary pins or by screws inserted in lag fashion. CLINICAL RELEVANCE: Surgical repair of femoral capital physeal fracture is most successful in younger cattle and can result in productive animals.

An adult, 23 yr-old, male greater one-horned rhinoceros (Rhinoceros unicornis) was repeatedly immobilized with combinations of etorphine, detomidine, and ketamine to provide medical and surgical care to chronic, bilateral, soft tissue lesions on the hind feet and to collect semen by electroejaculation. The rhinoceros was successfully immobilized on 24 occasions over a 55 mo period at approximately 8-10 wk intervals, 17 times with a combination of etorphine and detomidine (M99-D, i.m.) by projectile dart and seven times with a combination of etorphine, ketamine, and detomidine (M99-K-D, i.m.) by pole syringe. The combination of etorphine, detomidine, and ketamine repeatedly and safely induced prolonged anesthesia, and a suitable drug combination includes 3.5-3.8 mg etorphine, 14 mg detomidine, and 400 mg ketamine (M99-K-D) administered i.m. into the neck.

OBJECTIVE: To evaluate signalment, surgical treatment, postoperative complications, and future breeding success or semen production in a group of bulls with naturally occurring disease of the scrotum or testis. STUDY DESIGN: Retrospective study. ANIMALS: 21 bulls that underwent unilateral castration after evaluation for scrotal swelling. PROCEDURE: A computer-assisted search of medical records at 2 veterinary teaching hospitals was performed. Historical, diagnostic, surgical, and follow-up data were collected and analyzed for those bulls with scrotal swelling that underwent unilateral castration. RESULTS: Four of 5 pasture breeding bulls and 9 of 10 semen collection-center bulls successfully bred cows or produced viable semen within 6 months of surgery. Fourteen of 21 surgical procedures were performed after induction of general anesthesia. Sixty-six percent of procedures were performed as open castrations. Seventy-one percent of bulls developed postoperative complications, most of which were mild swellings. Unilateral castration returned 13 of 15 bulls with unilateral disease of the scrotum or testis to productive service by 6 months after surgery. CONCLUSION AND CLINICAL RELEVANCE: Unilateral castration is an effective treatment for unilateral disease of the,scrotum or testis in bulls, allowing return to reproductive function.
