Supine Percutaneous Nephrolithotomy: Preliminary experience in a single hospital

Background and Objective: 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. Methods: 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. Results: 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). Conclusion: 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.
