Finger Length Ratio and Urinary Stone Disease
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This study looks at whether the length ratio of your index finger to ring finger (2D:4D) is related to having kidney or ureter stones. It compares people with stones to those without stones, using a simple hand measurement.
Summary written for real people, not researchers, by Clin2.

- You are 18 years old or older.
- You have had a non-contrast CT scan of your abdomen or pelvis at Malatya Training and Research Hospital during the study period.
- If you have a kidney or ureter stone, you can join as a case. If you have no stones in your kidneys, ureters, or bladder, you can join as a control.
- For controls: you have never had a doctor-diagnosed kidney stone or stone surgery before.
- You do not have any hand or finger deformity, injury, or surgery that makes measuring your fingers difficult.

This trial compares two types of disposable flexible ureteroscopes to see which works better for removing kidney stones in children. If your child has a single kidney stone or multiple stones that add up to less than 20 mm, this study may help guide better treatment.
This study measures the angle of your ureter (the tube that carries urine from your kidney) on imaging scans to predict whether a camera-based stone removal procedure will need to be converted to a larger surgery. Understanding this angle may help doctors prepare better and improve outcomes.
This study compares two different ureteral access sheaths used during flexible ureteroscopy (a scope through the urinary tract) to treat kidney stones. It aims to see if one type leads to better outcomes than the other.
This study looks for “biomarkers,” which are measurable signs in samples like urine or blood, to help understand and detect recurring urinary stone disease. It may help future patients by improving how doctors predict stone recurrence or identify stone types.
This trial tests a specific flexible scope (Shenzhen HugeMed 6.3 French) for removing kidney or ureter stones. It looks at how well it works, costs, and recovery, and may be a good option if you have stones smaller than 2.5 cm and need your first such surgery.
This study looks at how uncomfortable or bothersome ureteral stents (small tubes placed in the urinary tract after kidney stone treatment) can be, and whether using imaging to pick the right stent length reduces symptoms. You'll answer questions about any stent-related discomfort you experience.
