Percutaneous Nephrolithotomy (PCNL) is recommended for large Kidney Stones. It is mostly done in prone position. However, PCNL in Supine position is another safe option. Only few centers in country are doing it and so it is challenging task to adopt supine PCNL approach in an institution initially. In this study our purpose was to assess initial experience of Supine PCNL in our center.
It is a preliminary retrospective study of our first fifty-one supine PCNL procedures, performed by a single Surgeon, over Twelve months period, from April 2021 to April 2022. We managed a retrospective review of patients' records. Analysis was completed by utilizing SPSS version 20. Implementation of Mean along with standard deviation values was utilized for continuous variables. While frequency/percentages represented categorical factors.
Patients mean age was 39 years, comprising of 62.74% male and 37.25% female patients. Thirty patients had their stones treated on the left side. Mean Stone burden was 3.2 cm. Most of the stones were GUYs score one and two (complexity wise). The mean procedure time 147minutes. Mean hospital stay of 2.17 days was observed in this study. Forty patients were stone free. Only seven patients (14%) had level I-II complications (Clavien-Dindo classification).
Supine PCNL can be adopted safely in an institute if careful selection of patients is done before surgery. In our center it had acceptable success rates and few complications.
经皮肾镜取石术（PCNL）适用于治疗较大肾结石。该手术大多在俯卧位下进行。然而，仰卧位PCNL也是一种安全的选择。国内仅有少数中心开展此项手术，因此，对于一个机构而言，最初采用仰卧位PCNL方法是一项具有挑战性的任务。在本研究中，我们的目的是评估我院中心开展仰卧位PCNL的初步经验。
这是一项初步的回顾性研究，回顾了2021年4月至2022年4月期间，由一位外科医生实施的首例51例仰卧位PCNL手术。我们对患者记录进行了回顾性分析。分析使用SPSS 20版本完成。连续变量采用均值及标准差进行分析。频率/百分比代表分类因素。
患者平均年龄为39岁，男性患者占62.74%，女性患者占37.25%。30例患者的结石位于左侧。平均结石负荷为3.2厘米。大多数结石的GUYs评分为1分和2分（从复杂性角度）。平均手术时间为147分钟。本研究中观察到平均住院时间为2.17天。40例患者结石清除。只有7例患者（14%）出现I-II级并发症（Clavien-Dindo分类）。
如果术前仔细选择患者，仰卧位PCNL可在机构中安全开展。在我院中心，该手术成功率令人满意，并发症较少。
