There are few reports on the use of PCNL for staghorn calculi in children. We evaluated the safety and efficacy of this technique, using adult equipment, in children below 16 years of age.
Data for pediatric patients undergoing PCNL for staghorn renal calculi was prospectively recorded. A staghorn calculus was defined as a branched stone occupying more than one part of the collecting system. A standard fluoroscopy guided PCNL was performed in the prone position using adult nephroscopes. Stone clearance was assessed on fluoroscopy and X-ray in all patients and an ultrasound or CT scan in selected cases.
Beginning October 2007, 33 pediatric patients underwent 34 PCNLs at our center. 12 of these children had staghorn calculi. All patients had normal renal function and no metabolic abnormality. One child had a solitary kidney. In 5 children, the primary tract was placed into the superior calyx and 4 of these were above the 12th rib. A 21Fr nephroscope was used through a 24Fr tract in 9 children while a 26Fr nephroscope was used through a 30Fr tract in 3 cases. 10 children were managed through a single tract. One patient each required SWL and ureteroscopy for residual fragments. 11 patients had complete clearance while 1 had insignificant residue. One child required intravenous antibiotics for post-operative fever while another developed an abdominal collection that was managed conservatively.
PCNL is safe and effective in the management of pediatric staghorn calculi.
