Percutaneous nephrolithotripsy for treatment of complex kidney calculi

【Objective】To summarize the clinical treatment experience of percutaneous nephrostomy followed by ureteroscopy and pneumatic lithotripsy,in order to seek a minimally invasive therapies for complex kidney calculi. 【Methods】To retrospectively analyze the clinical data of 19 patients with complex calculi in kidney treated by per-cutaneous nephrolithotripsy (PNL).【Results】Mean operative time was 120 min with an average estimated blood loss of 80 ml. The free stone rate was 91% in 19 patients. One-off removal of calculi was in 15 cases. At twice removal were in 4 cases. Single nephrostomy access track was required for clear off stone fragments in 15 patients,and dou-ble nephrostomy access tracks were required in 4 patients. With the exception of hemorrhage and urosepsis,no se-vere complications were observed. Average hospital times were 8 days.【Conclusions】Percutaneous nephrolithotrip-sy by use of rigid ureteroscopes be of advantages with small wound,lower residual stones rate,less complications and rapid recovery. It is a safe,minimally trauma and effective methods for treating complex calculi in kidney.
