An interventional study of Performed flexible and navigable suction ureteral access sheath combined with needle perc and PCNL in Urinary Calculi, sponsored by Beijing Tsinghua Chang Gung Hospital. Not yet recruiting. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2025-04-07.
Sponsored by Beijing Tsinghua Chang Gung Hospital · Not applicable, Interventional, and Treatment
The goal of this clinical trial is to learn if flexible and navigable suction ureteral access sheath combined with needle perc works to treat partial staghorn renal calculi. It will also learn about the safety of drug ABC. The main questions it aims to answer are:

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
