Percutaneous nephrostomy in neonates, infants, and children.
In a 20-month period, 13 percutaneous nephrostomies were placed in 10 pediatric patients ranging in age from one day to six and one-half years. The procedure was successful in all cases with no significant complications. Final diagnoses included ureteropelvic junction obstruction, ureterovesical junction obstruction, posterior urethral valves, and pyonephrosis. Localization of the obstruction as detected on initial antegrade nephrostography was found to be incomplete or incorrect in three patients. In one patient, both ureteropelvic and ureterovesical junction obstruction were present. In the other two patients, the misdiagnosis probably related to the difficulty of filling a distended, obstructed ureter prior to drainage.
