[Glycine poisoning after percutaneous kidney surgery].

We describe two cases of altered consciousness associated with nausea and vomiting after renal surgery. These events occurred respectively one and two hours after surgery. They are believed to be caused by the transfer of large amounts of irrigating solution containing glycine 1.5%. The effects of hyponatraemia (132 and 129 mmol.L-1) and glycinaemia (3518 and 8589 mmol.L-1) are discussed. We conclude on the importance of an early clinical diagnosis completed by biological investigation to allow an adequate symptomatic management.
