Measuring the kidneys-practical applications using a growth and hypertrophy chart.

A graphic and practical method for displaying renal growth utilizes a growth-hypertrophy chart. It is best suited for following renal growth on sequential intravenous urograms in patients with urinary tract infection, reflux and problems in which renal growth reflects the efficacy of therapy. The chart uses established standards for normal kidney length, and rates of growth and hypertrophy, and enables one to tell at a glance whether the renal growth is normal. Pitfalls both in the method of measuring the renal lengths and in the interpretation of the measurements are discussed.

Combined portal and vena caval hypertension in Gaucher disease: The value of preoperative venography.

Portal hypertension in Gaucher disease is unusual; the seventh known patient with this complication is reported. Prior to portacaval shunting in this child, a localized obstruction of the inferior vena cava at the subdiaphragmatic level was demonstrated by caval manometry and inferior vena cavography. At autopsy, centrilobular hepatic fibrosis seemed to be responsible for the portal hypertension. Nodular enlargement of the right and caudate lobes of the liver was the cause of the caval obstruction; elevated caval resistance may have contributed to the portal hypertension and possibly was responsible for failure of a portacaval anastomosis. The value of preoperative inferior vena cavography in addition to arterial portography in children with portal hypertension is stressed.

A safe, simple and reliable method for percutaneous (closed) renal biopsies in children: results in 100 consecutive patients.

A safe, simple and reliable technique for percutaneous renal biopsy in children has been described. Specimens adequate for pathologic interpretation were obtained in 97 patients. Significant complications (gross hematuria lasting more than 36 hours, severe pain, perirenal mass or unexplained fever) occurred in 8 patients. No secondary operations or transfusions were required. No mortailty or late complications occurred.

Fate of 90 children with ileal conduit urinary diversion a decade later: analysis of complications, pyelography, renal function and bacteriology.

A study of the long-term results of ileal conduit urinary diversion for non-malignant disease in 90 children has shown that there were 75 survivors after 10 to 16 years. Stomal stenosis and ureteroileal or other intrinsic obstructions requiring ileal loop revisions occurred frequently and as late as 13 years postoperatively. Of 144 renal units 76 per cent improved or remained stable and 69.3 per cent of normal kidneys remained normal after more than a decade of urinary diversion. In order to obtain these results close lifetime followup and aggressive loop revisions have been required. Urine cultures were consistently negative in 70.5 per cent of all patients. Good results were obtained in terms of preservation of renal function in all categories. Creatinine clearance remained in the normal range after 10 years if the excretory urogram remained normal. Ileal conduit urinary diversion remains a major surgical undertaking but it also remains the standard of urinary diversion against which all other methods must be judged. The results in terms of renal preservation are impressive but so too are the significant number of long-term complications. Any other method of diversion (such as the sigmoid conduit) that can improve upon these results will be welcomed. All children with ileal conduit urinary diversion for reasons other than a neurogenic bladder must be considered candidates for urinary reconstruction.
