The effect of peri-operative blood transfusion on survival after surgery for renal carcinoma was studied in 201 patients. In addition to blood transfusion, several other factors were included in a multivariate analysis. Using Cox's proportional hazards model, transfusion of more than 4 units of blood was found to be an independent prognostic factor in addition to tumour stage, erythrocyte sedimentation rate and macrohaematuria.

In the treatment of acute ureteral colic opinions differ regarding the consequences of fluid intake. This study was undertaken to evaluate a possible relationship between fluid load and the pain. One group of patients received 3 liters of fluid intravenously, while in another group all fluids were withheld. No intergroup differences as regards pain was found after 6 hours of observation.

The effect of fluid load on pain was estimated in 60 patients with acute ureteral colic treated with 50 mg. intravenous indomethacin. One group received 3 l. fluid intravenously, while in another group all fluids were withheld for 6 hours. Pain was assessed with a visual analogue scale. No intergroup difference in regard to pain was found after 1, 3 and 6 hours of observation.
