Myiasis (maggots) around nephrostomy tube

Abstract

Myiasis is caused by the presence of dipterous larvae in humans and animals. It is usually associated with poor hygienic conditions. A urologist rarely comes across myiasis. We report a case of myiasis around a recently placed nephrostomy tube. A 55-year-old male farmer from a rural area underwent right percutaneous nephrolithotomy. The procedure was terminated because of bradycardia and arrhythmia. There were residual calculi. A nephrostomy was kept. His relook nephroscopy was planned, but he was not willing. Hence, he was discharged with an indwelling nephrostomy tube. Two weeks later, he presented with severe pain around the right nephrostomy tube with surrounding pruritus. The wound hygiene was poor. He was found to have maggots around the nephrostomy tube. These were treated by local instillation of turpentine oil and oral and topical ivermectin, followed by manual removal of the maggots.
