Surgical management of comorbid pyometra and cystic calculus in a Spitz dog

Abstract

A six year old female nulliparous spitz dog weighing 4.5 kg was presented with the history of anorexia, vomiting, oliguria and not voiding faeces for past 3days. On clinical examination, distended abdomen, moderate dehydration and pus discharge from the vulva were observed. Radiological examination revealed cystic calculus and ultrasonography confirmed the presence of calculus in the bladder along with distended and sacculated uterine shadow suggestive of pyometra. Hemato-biochemical analysis revealed absolute neutrophilia with increased blood urea nitrogen and creatinine level. Under diazepam premedication, propofol induction, anaesthesia was maintained with isoflurane using variable vaporizer setting. Cystotomy was performed and removed a single calculus measuring around 3 cm lengths and the bladder was closed with PGA 3-0 in double layer inversion suture pattern. Ovariohysterectomy was performed as per standard operating procedure. Postoperatively fluid therapy, antibiotics, opioids and urinary acidifiers were administered. Urine analysis revealed phosphate crystals. Animal recovered uneventfully.
