Plain-English summary
A 9-year-old mixed-breed dog was brought in for a second opinion after being diagnosed with kidney and bladder stones. He underwent surgery to remove the stones and had some complications afterward, including inflammation and pain in the genital area. A follow-up test revealed that some of the contrast used during imaging had leaked into the surrounding tissue, but thankfully, the dog improved with treatment. Six months later, a follow-up exam showed he had fully recovered and was doing well.

Abstract
A 9-year-old 6-kg male castrated mixed-breed dog was admitted to the hospital as a second opinion for left-sided nephrectomy. Plain radiographs, ultrasound, excretory urography and retrograde urethrography revealed left-sided hydronephrosis and calculi in the bladder and urethra. The urethral calculi were hydropropulsed into the bladder and nephrectomy and cystotomy were performed. Three days after surgery, the patient showed preputial inflammation, pain and pollakiuria. Retrograde urethrography was repeated and extra-urethral leakage of contrast medium into the penile tissue was identified, followed by filling of the draining veins, reaching the caudal vena cava, with subsequent opacification of the right renal pelvis and ureter and opacification of a lymph node. The dog improved during hospitalisation and a retrograde urography performed 6 months after the initial surgery confirmed full recovery.
