Abstract

Aim: To evaluate efficacy and morbidity of the treatment in total 533 patients underwent percutaneous nephrolithotomy (PCNL).

Material and Methods: Between November 2004 and December 2011, the records of 533 patients with renal calculi who underwent PCNL were reviewed retrospectively. All patients were evaluated with intravenous urography and/or computerized tomography. Patient related factors such as age, body mass index (BMI), ipsilateral history of SWL, PCNL and open surgery together with stone size and localization and degree of hydronephrosis were noted. Number and localization of access, blood transfusion requirement, success rate, length of hospitalization, intraoperative and postoperative complications and secondary procedures were reviewed.

Results: The application of 533 PNL procedures, 226 women (%47.5), 280 men (%52.5), %47.5 right side, %52.5 left side, BMI 26.38 kg/m2, mean stone volume 4196.64 mm3 were determined. Before the PNL procedures, 134 patients were used ESWL(%25.1), open nephrolithotomy in 77 patients (%14.4), PNL 29 patients (%5.4) applied. 221 patients didn’t have hydronephrosis (%41.5), 312 patients had hydronephrosis (%58.5) was detected before the PNL procedures. 407 patients underwent single-port (%76.4), 2 ports with 86 patients (%16.1), 38 patients with 3 ports (%7.1), 1 patient was 4 port input. Balloon dilatator (%81.6), sequential dilatator (%17.8) were used. The mean of operation and fluoroscopy time 125.91 min and 6.1 min were detected. Perioperative complications occured in 39 patients (%7.1). Required blood transfusion in 81 patients (%15.2).

Conclusion: PNL method acceptable complication rate in the treatment of kidney Stones, can be administered safety and effectively.
