Outpatient tubeless percutaneous nephrolithotomy:the initial case series

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) has traditionally been performed on an inpatient basis. To the best of our knowledge, this is the first report of tubeless PCNL on a completely outpatient basis. The purposes of this study were to assess the safety and efficacy of outpatient PCNL. METHODS: We reviewed the initial consecutive outpatient tubeless PCNLs performed at our institution by a single surgeon. Patients were discharged home the day of surgery only after meeting strict discharge criteria. Preoperative, intraoperative and postoperative data were collected prospectively. RESULTS: Outpatient tubeless PCNL was performed in 3 patients. The mean maximum stone diameter was 14 mm. The average hospital stay was 175 minutes. All 3 patients were discharged home in stable condition after meeting all of the inclusion criteria. There were no emergency room visits or hospital readmissions postoperatively. The mean follow-up period was 47 days. All stones were calcium oxalate and the stone free rate was 100%. There were no minor or major complications. CONCLUSION: In properly selected patients, outpatient tubeless PCNL is safe and effective. Our initial experience with outpatient PCNL has been favourable and warrants further investigation in a larger patient population.
