The value of split renal function in severe neonatal and infant pelviureteric obstruction managed by percutaneous nephrostomy.
A percutaneous nephrostomy (PCN) was inserted as part of the management in 17 newborns and infants with severe pelviureteric junction obstruction between 1981 and 1993. Nephrectomy was performed in eight cases and pyeloplasty in nine cases, successfully in six cases (mean follow-up: 7.7 years). PCN was useful for predicting that no non-functioning kidney on intravenous pyelography (IVP) in this series should have been preserved. Among the kidneys with a high excretion delay on IVP, PCN showed that only those that had a split creatinine clearance of more than 1 ml/min/1.73 m2, or theoretical clearance for age and weight of over 6%, should be preserved.
