PURPOSE
Micro percutaneous nephrolithotomy (Microperc) is one of the minimally invasive procedures for the treatment of urinary
stone disease. In this video we aimed to demonstrate how we do micro percutaneous nephrolithotomy in children
MATERIAL AND METHODS
A 7-year old girl complaining of abdominal pain was found to have three kidney stones, largest one 7 mm in diameter in
the left renal pelvis by KUB and CT scan. A micro percutaneous nephrolithotomy was planned for her.
RESULTS
Under general anesthesia the patient was placed in supine position. A 5-Fr ureteral catheter was placed into the left
kidney over a glide wire via a 9.5 Fr ureteroscope. Then the patient's position was changed to prone. Access to the left
kidney was made through the middle zone under direct visualization by a 0 degrees optic through an "all-seeing needle"
under scopic guidance. Three kidney stones, largest one 7 mm in diameter were observed in renal pelvis. Then the
stones were fragmented by using holmium:YAG laser. Following totally fragmentation of the stones, a 4.7 Fr/16 cm
ureteral double-J stent was placed into the left kidney. After confirmation of the stone-free status on postoperative day
1 with a KUB, urethral catheter and double-j stent was removed and the patient was discharged on the same day.
Anesthesia time was 65 minutes, scopy 3 minutes and hospital stay was 1 day.
CONCLUSIONS
Micro percutaneous nephrolithotomy technique, that shown step by step in this video, is an effective and safe procedure
for the minimally invasive treatment of selected kidney stones in children.
