Purpose: To determine the effect of previous single or multiple open stone surgeries on percutaneous nephrolithotomy (PCNL) results and complications.

Materials and Methods: We reviewed medical records of 1422 patients who had been undergone PCNL in our institute between 1998 and 2011 by the same surgeon. Patients were divided into 3 groups. The first group included patients with no history of previous ipsilateral open stone surgery (n = 711). Patients in second group had been undergone only one open stone surgery before PCNL (n = 405) and patients with more than one previous open stone surgery were placed in third group (n = 306). We compared operation duration, stone free rate (SFR), number of  attempts to access the collecting system and intraoperative and postoperative complications between 3 groups.

Results: There were no differences in sex, body mass index, stone burden and laterality between 3 groups. Operation time was significantly shorter in the first group (P = .000) while there was no statistically significant differences in operation duration between second and third groups (> .973). The number of attempts to enter the collecting system was significantly lower in the first group in comparison to other two groups (P = .00). We didn’t find significant differences between 3 groups in hospital stay, SFR, intraoperative and postoperative complications.

Conclusion: Our findings demonstrated that PCNL can be performed in patients with one or more open stone surgery history successfully without further complications.
