A 60-year-old man visited our hospital with a complaint of right renal incidentaloma which was pointed out on abdominal ultrasonography for a medical check-up. Abdominal computed tomography showed a renal tumor in the right kidney, which was a slightly high-dense relative to the renal parenchyma and was enhanced in the arterial phase. The tumor had grown gradually from 1.4 to 1.7 cm in diameter. After the observation for 4 years, he underwent pure laparoscopic non-ischemic partial nephrectomy using a microwave tissue coagulator. Histological examination of the specimen revealed a leiomyoma of the kidney. This is the 5th case of successful laparoscopic partial nephrectomy for renal leiomyoma in Japan within the retrieved references.
