title: [Anuria due to bilateral renal artery spasm during hysterectomy and oophorectomy].
abstract: A decrease in urinary volume during surgery is often encountered. Usually it can be treated with intravenous fluid or diuretics. We here report a rare case of intraoperative anuria in which renal blood flow ceased totally. The patient was 36 year old female (166 cm 50 kg), who was admitted for a investigations of long-term severe hypertension of unknown origin. Radiographic examination showed no adrenal tumor but a right ovarian cyst was found and suspected to be malignant, for which oophorectomy was indicated. After epidural catheterization, general anesthesia was induced by intravenous propofol and vecuronium, and maintained with epidural lidocaine and the inhalation of isoflurane and nitrous oxide mixed with oxygen. During surgery, urinary outflow decreased gradually leading to total anuria, which was resistant to intravenous fluid and furosemide. Intraoperative pyelography was performed and both kidneys and urinary tracts were not visualized. After the surgery, when the patient returned to the ward, urine began to flow. Postoperative pathological examination of the removed ovary showed a presence of renin excreting tumor cells. The anuria was considered to be the result of transient spastic obstruction of bilateral renal arteries, presumably in response to a high level of plasma renin.
