History A 47-year-old man presented with palpitations and decreased exercise tolerance. A peripheral blood smear revealed anemia, thrombocytopenia, and blast cells, and a diagnosis of acute myeloid leukemia was made. Immunohistochemistry revealed positivity for cluster of differentiation (or CD) markers, which have been reported to be associated with an increased risk of extramedullary leukemic involvement. Thus, contrast material-enhanced computed tomography (CT) of the thorax, abdomen, and pelvis was requested to enable exclusion of any extramedullary extension of leukemia. Unenhanced and contrast-enhanced nephrographic phase CT was performed. Follow-up CT 3 months later showed minimal interval change in the lesion (images not shown).

We describe a case of an infant born at 39 weeks of gestation who was in the neonatal intensive care unit for postoperative management of congenital heart disease and underwent bedside ultrasound-guided percutaneous cystostomy to treat an iatrogenic urethral injury. The procedure was uneventful, successful, and no complications were noted. This case demonstrates that this procedure is safe and minimally invasive. Indications, contraindications, techniques, potential complications, and the safety of performing this procedure in a bedside setting are discussed.
