Giant bladder calculus in a patient with recurrent urinary tract infections

Resumen

A giant bladder stone is rare and is usually defined as “giant” if its weight is over 100g. We describe a 43-year-old man who presented with urinary sepsis, hypotension, abdominal pain, and a vesicocutaneous urinary fistula. Laboratory tests showed hemoglobin 6.6 g/dL, leukocytes 22,700/mm³, creatinine 7.29mg/dL (eGFR 8.8mL/min/1.73m2), urea 181 mg/dL, serum pH 6.99 and bicarbonate 6 meq/L. Abdominal tomography showed bilaterally reduced cortical thickness of the kidneys and a bladder stone of 6x6x11 cm. He was treated with antibiotic therapy, dialysis, and open cystolithotomy. Clinical improvement was observed, despite kidney disease persistence, with chronic dialysis therapy.
