Recruiting
Conditions
Percutaneous Nephrolithotomy

Procedure: one-handed technique
Registration Number
NCT05661175
Lead Sponsor
The First Affiliated Hospital of University of South China
Brief Summary

Percutaneous nephrolithotomy(PCNL) is a surgical method for upper urinary calculi.Traditional percutaneous nephrolithotomy usually requires the lithotripsy with the left hand holding the nephroscope and the right hand adjusting the laser fiber,which requires a lot of practice to master this technique.The goal of this study is to explore the safety and effectiveness of the PCNL with one-handed lithotripsy technique

Detailed Description

This is a key clinical research project of the University of South China(NO.USCKF201902K01).The goal of this study is to compare the safety,effectiveness and feasibility between the percutaneous nephrolithotomy with one-handed technique and the traditional percutaneous nephrolithotomy in the treatment of upper urinary calculi. 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.For random allocation,participants are randomly grouped by coin toss method.Participants with front side are assigned to experimental group,where they undergo PCNL with one-handed lithotripsy.Participants with reverse side are assigned to control group and undergo traditional PCNL.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.

Primary Outcome Measures
NameTimeMethod
Stone clearance rateDay 2 after the surgery

Preoperative and postoperative stone dimensions are compared by radiological assessment. Postoperative residual calculi \< 4 mm in diameter reflect complete removal of calculi (stone-free rate = 100%)

Renal pelvis mucosal injury rateduring the procedure

Number of accidental injuries of renal pelvis mucosa during operation

Operative timeduring the procedure

From the completion of anesthesia to the end of the suture incision.

Changes in renal bleeding after surgeryHour 3 after the surgery

Pre- vs. post-operative difference in hemoglobin and hematocrit values

Secondary Outcome Measures
NameTimeMethod
Hospital stayimmediately after the discharge

The number of days from hospitalization to discharge

Hospital costsimmediately after the discharge

The cost from hospitalization to discharge.
