Medical management of urethral obstruction complications
A 2-year-old intact male cat presented for lethargy, vomiting, and hematuria. Bloodwork revealed severe azotemia and hyperkalemia. The patient was diagnosed with urethral obstruction and was treated with urethral catheterization, calcium gluconate, IV fluid therapy, buprenorphine, and prazosin.
Since the patient improved, the urinary catheter was removed. The patient later developed pyrexia, worsening azotemia, hypoalbuminemia, hyperbilirubinemia, and dysuria. Abdominal radiographs revealed unilateral renomegaly, and abdominal ultrasound revealed left perinephric fluid. Perinephric fluid revealed septic inflammation. Fluid from the abscess and urine grew Pasturella spp. The patient was treated with perinephric catheterization, saline lavage, and a continuous infusion of cefotaxime for 72 h. The patient's azotemia quickly resolved, and the patient was discharged after 6 days of hospitalization and made a full recovery.
