Abstract
To determine the effect of previous single or multiple open stone surgeries on percutaneous nephrolithotomy (PCNL) results and complications. 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. 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 (P > .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. Our findings demonstrated that PCNL can be performed in patients with one or more open stone surgery history successfully without further complications.
