title: [A case of infected urachal cyst successfully drained by a catheter perforating the bladder].
abstract: A 42-year-old man complained of lower abdominal pain. Computed tomographic scan and magnetic resonance imaging revealed an infected urachal cyst. A drainage catheter, which had multiple holes over a 10 cm length from the catheter tip, was placed in the urachal cyst. The catheter was inserted from the subumbilicus region and the catheter tip was intended to be situated at the caudal end of the urachal cyst. However, the catheter tip accidentally perforated the bladder and urine flowed out of the bladder through the catheter. Because the urine diluted and washed out the pus in the urachal cyst, the infected urachal cyst was successfully drained. Percutaneous drainage and antibiotics allowed resolution of the inflammatory process. On the twenty-third day after catheter placement, excision of the urachal cyst and partial cystectomy were performed with relative ease and without any complications.
