BACKGROUND/AIM: Open or percutaneous renal stone surgery can have an adverse effect on the collecting system of the kidney. We evaluated retrograde intrarenal surgery outcomes in patients with ≤30 mm renal stones who had open or percutaneous renal stone surgery history.
A total of 707 patients who underwent retrograde intrarenal surgery treatment were included in this study. Fifty-six patients had open or percutaneous renal stone surgery history (Group 1) and the remaining did not (Group 2, n = 651). The groups were compared in terms of age, stone size, stone-free rates, and complications.
The mean age of the patients was 51.16 ± 14.8 and 45.95 ± 14.6 years in Groups 1 and 2, respectively (p = 0.008). The mean stone size was 14.97 ± 6.1 mm and 16.47 ± 6.9 mm in Groups 1 and 2, respectively (p = 0.107). The stone-free rates were 71.4% and 84.1% in Group 1 and 2 respectively and it was significantly higher in Group 2 (p = 0.013). The overall rate of postoperative complications was higher in Group 1 (p = 0.019), but there was no difference between the two groups in terms of Clavien 1–2 and 3–4a complication rates.
Our results showed that having a history of open or percutaneous renal stone surgery has a negative effect on the success and complication rates in retrograde intrarenal surgery. Therefore, patients should be well informed before this operation.
背景/目的：开放或经皮肾镜取石术可能会对肾脏集合系统产生不良影响。我们评估了有开放或经皮肾镜取石术史的≤30mm 肾结石患者行逆行肾内手术的结果。
共纳入 707 例接受逆行肾内手术治疗的患者。56 例有开放或经皮肾镜取石术史（组 1），其余 651 例无（组 2）。比较两组患者的年龄、结石大小、结石清除率和并发症。
患者的平均年龄分别为 51.16±14.8 岁和 45.95±14.6 岁（p=0.008）。组 1 和组 2 的平均结石大小分别为 14.97±6.1mm 和 16.47±6.9mm（p=0.107）。组 1 和组 2 的结石清除率分别为 71.4%和 84.1%，组 2 明显更高（p=0.013）。组 1 的术后总体并发症发生率较高（p=0.019），但两组的 Clavien 1-2 和 3-4a 并发症发生率无差异。
我们的结果表明，有开放或经皮肾镜取石术史会对逆行肾内手术的成功率和并发症发生率产生负面影响。因此，在进行手术前应充分告知患者。
