Tubeless Percutaneous Nephrolithotomy Without Reverse Insertion of a

Status Recruiting

Clinical Trial 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.

Clinical Trial Description

This is a key clinical research project of the University of South China (No. USCKF201902K01). The goal of this study is to comparative the safety and clinical efficacy between the tubeless percutaneous nephrolithotomy without reverse insertion of a ureteral catheter and the traditional tubeless percutaneous nephrolithotomy with reverse insertion of a ureteral catheter in the treatment of upper urinary calculi, and to explore the former' applications. It is a prospective, randomized controlled single center study that is conducted for 2 years anticipatively. The clinic physician is responsible for patient recruitment and allocation and the application of computerized random-number generation. For random allocation, participants are given random numbers. Participants with odd numbers are assigned to experimental group, where they undergo tubeless PCNL without reverse insertion of a ureteral catheter. Participants with even numbers are assigned to control group and undergo tubeless PCNL with reverse insertion of a ureteral catheter. The doctors managing the operations accept participants and execute the surgical treatments. All participants sign clinical-trial informed consent and surgical informed consent during the preoperative conversation. Follow-up observation is conducted for 1 month after surgery. After completion of the study, we collect relevant clinical data from the participants. The primary and secondary outcomes are analyzed and compared between the two groups. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
