ABSTRACT
A 65-year-old woman with a history of a left heminephrectomy for renal carcinoma developed hypercalcaemia 11 years after the operation. The same kidney was found to contain a recurrent renal carcinoma. After the radical nephrectomy of the left kidney, hypercalcaemia remitted but reappeared 11 months later. The right kidney was small but functioned at a level of creatinine clearance of 10--15 ml/min. Metastatic work-up was negative, and secondary causes of hypercalcaemia were excluded. A neck exploration revealed a parathyroid adenoma. With parathyroid resection the serum calcium declined to normal, and the risk of hypercalcaemic nephropathy in the remaining kidney was precluded.

A study by questionnaire was sent to 134 Surgical Services at Veterans Administration Hospitals to ascertain the prevalence of the practice of preoperative hydration during the period of hydropenia preceding surgery. A 92.5 per cent response was noted and the following conclusions are drawn: (1) The majority of Veterans Administration Surgical Services do not routinely provide intravenous fluids during the immediate preoperative period. (2) Affiliation with a medical school-based postgraduate training program does not alter significantly the proportion of Surgical Services providing preoperative intravenous therapy on a routine basis. (3) These observations suggest a need for Surgical Services to assess the desirability and indications of preoperative hydration. (4) However, in the case of chronic renal failure patients there is little question of the necessity for careful preoperative, intraoperative, and postoperative hydration.

In gastric tubes interposed between small bowel a clear wave pattern was found, differing markedly from the bowl above and below. The gastric tube appears to be not an inert conduit since it continues to exhibit automatic rhythmic contraction. The possibility of slowing intestinal transit by the interposition of an antiperistaltic gastric tube seems to be supported by the demonstration of regular contraction.
