Non-visualizing kidney

Two-hundreds and fourty-seven patients showed non-functioning kidney, either unilateral or bilateral, on IVP for 3.5 years of 1964 to 1967. They were statistically investigated regarding sex, affected side, age, chief complaints, renal diseases, examinations further performed, treatments, etc. The hospitalized cases were precisely studied besides. Recently, non-visualizing kidney after surgery for carcinoma of the cervix has been remarkably increasing in number. Delayed excretory pyelograms taken after injection of double dosage of contrast dye seemed to be the best diagnostic method for non-visualizing kidney. Renal function studies of the patients with non-visualization on routine IVP showed that majority of them had RPF below 100 cc/min and creatinine clearance below 10 cc/min. As to treatment, nephrectomy was the operation most frequently performed on such kidney.
