NCT ID: NCT04871984 Not yet recruiting - Renal Stone Clinical Trials

Effectiveness of Holmium and Thulium Lasers With Ureteroscopy for Urinary Lithiasis

LiThuHol
Start date: May 2021
Phase:
Study type: Observational [Patient Registry]

Holmium laser is the current gold standard for lithotripsy on urinary lithiasis, while Thulium is brand new. The latter has been released in July 2020 in Europe, and only in-vitro studies have been published. The aim of this study is to compare the stone free rate in ureteroscopy, for all consecutive patients treated with laser fragmentation, between both Holmium and Thulium lasers. The costs and complications will also be studied.

NCT ID: NCT04504084 Not yet recruiting - Clinical trials for Shared Decision Making

Influence of Patient Decision-Making Aids for Patients With Unilateral Ureteral Stone: A Randomized-Controlled Trial

Start date: September 1, 2020
Phase: N/A
Study type: Interventional

Ureteral stone is a common disease with high prevalence and recurrence rate in Taiwan. Taiwan is located in subtropical zone, where urolithiasis is commonly seen. A national survey in Taiwan determined that 9.6% of the population suffered stones throughout their lifetime. Symptoms of ureteral stone include renal colic, hematuria, and urinary tract infection. Without proper treatment, ureteral stone could lead to renal function impairment such as acute kidney injury (AKI) or chronic kidney disease (CKD). There are several treatment options for ureteral stone, such as ureteroscopic lithotripsy (URSL), flexible urteroscopic lithotripsy (F-URSL), percutaneous nephrolithotomy (PCNL), extracorporeal shock wave lithotripsy (ESWL), and Medical expulsive therapy (MET). However, there are only few minutes from diagnosis of ureteral stone to possible treatment options explanation. It's difficult for patients to well understand all the details of possible treatments under such circumstances. Therefore, we design a patient decision aid (PDA) for unilateral ureteral stone to help patients understand all the treatment options. The PDA is standardized, written in plain language and patient-centered, with pictures attached.
