A 79-year-old woman with a history of total hysterectomy for cervical cancer with ureterocutaneostomy presented with high fever. She had tenderness and a hard lump around the ureterocutaneostomy site. Computed tomography scan revealed 1.5 cm ureteral calculus in ureterocutaneous fistula (Fig. 1A) associated with bilateral hydronephrosis (Fig. 1B) and we performed a transureteral stent insertion. Blood culture grew methicillin-sensitive Staphylococcus aureus (MSSA), Haemophilus parainfluenzae, Veillonella species and Bacteroides fragilis and urine culture revealed Escherichia coli, MSSA, and Enterococcus faecalis. The patient's clinical signs and symptoms gradually improved with ampicillin/sulbactam. Patients with urinary diversions including ureterocutaneostomy and iliac conduits are at increased risk of urolithiasis (1), which can cause sepsis, pyelonephritis, and renal insufficiency (2). Since most patients become colonized with a multitude of bacteria including Enterobacteriaceae and skin flora such as Staphylococcus aureus and Streptococcus spp., we should empirically treat with broad-spectrum antimicrobials until the culture results are available. Early diagnosis and urological intervention are required because it can be life-threatening with delayed treatment.
