[Prostate transurethral resection syndrome].
The "transurethral resection of prostate" syndrome (TURPS) is the clinical manifestation of the resorption into the patient's body of a large amount of glycocolle-containing irrigating fluid used for this procedure. The full clinical picture, which is seldom seen, consists of dyspnoea, nausea, arterial hypertension, an increased central venous pressure, cerebral oedema, cardiogenic shock and renal failure. Improved surgical techniques, as well as incomplete and atypical forms of the syndrome could explain this low incidence. Absorption into the blood stream may be rapid, by way of the prostatic venous plexi, or slower, from the spaces around the prostate and under the peritoneum. The present-day pathophysiological theory explains this syndrome by an acute hyponatraemia, sometimes dissociated from the hypoosmolality, the toxicity of glycocolle, and the neurological effects of hyperammonemia. Acute hyponatraemia, with blood sodium concentrations below 115 to 120 mmol.l-1, should be considered as potentially serious. The different mechanisms involved may act alone or together, thus explaining that the minor forms of the syndrome mostly consist of a neurological picture. The emergency treatment depends on the natraemia. It includes diuretics and progressive reloading of the patient with sodium in case of severe hyponatraemia with seizures. The best prevention is a correct surgical indication and technique. The resection should not last for more than 90 to 120 min. The major problem remains the early diagnosis of TURPS. Carrying out this surgery under regional anaesthesia is helpful for this purpose, but, in the near future, the best means might be the monitoring of expired ethanol concentrations.
