Abstract

INTRODUCTION

Percutaneous nephrolithotomy (PNL) in technology today with the development of the equipment used from 1980, the stone-free rate increase, reduction in operation time, with a reduction in length of hospital stay has become more reliable and efficient. However, the perioperative and postoperative complication rates decreased over time but did not disappear. PNL has substituted of open stone surgery as a minimally invasive method. In this study, we aimed to determine the differences in the complications developed according to the modified Clavien system and the modified Clavien system adapted for PNL.

METHODS

The study included 1011 PNL operations performed in 980 renal units in 928 patients who underwent PNL operation between November 2004 and January 2013 in our clinic. Preoperative, operative and postoperative data were evaluated retrospectively for each unit. Complications developed in patients were classified according to the modified Clavien system and the modified Clavien system adapted for PNL.

RESULTS

The complication rate was %18.29 in all cases. According to Clavien's classified, there were 23 (%2.27) complications in grade 1, 143 (%14.14) complications in grade 2, 11 (%1.08) complications in grade 3A, 6 (%0.59) complications in grade 3B, 4 (%0.39) complications in grade 4A, 15 (%1.48) complications in grade 4B were seen, but no complication according to grade 5 was observed. According to the modified Clavien classified for PNL, 23 (%2.27) complications in grade 1, 144 (%14.24) complications in grade 2, 22 (%2.17) complications in grade 3A, 9 (%0.89) complications in grade 3B, There were 4 (%0.39) complications in grade 4A, but no complications according to grade 4B and 5.

DISCUSSION AND CONCLUSION

Classification according to modified Clavien system adapted to PNL did not show any difference in low-grade complications; there was a decline in high-grade complications. Therefore, we think that classifying according to modified Clavien system adapted to PNL is more objective.
