Tubeless Percutaneous Nephrolithotomy Without Reverse Insertion of a Ureteral Catheter
Trial Parameters
Brief Summary
Percutaneous nephrolithotomy(PCNL) is a surgical method for upper urinary calculi. The advent of tubeless PCNL (without indwelling nephrostomy tube) has been proved to be safe and effective in reducing postoperative discomfort, shortening hospitalization time and reducing hospitalization costs. Traditional tubeless PCNL usually involves retrograde insertion of the ureteral catheter, which may cause many ureteral related surgical complications. However, there are few reports on tubeless PCNL without reverse ureteral catheter insertion. The goal of this study is to explore the safety and effectiveness of the tubeless PCNL without reverse ureteral catheter insertion.
