NCT ID: NCT06465784 Completed - Ureteric Stone Clinical Trials

Laser Lithotripsy for Ureteral Stones

Start date: March 1, 2023
Phase: Phase 4
Study type: Interventional

Objectives: To present the outcomes of retrograde and antegrade ureteroscopic laser lithotripsy in the treatment of proximal ureteral stones ranging in size from 10 to 20 millimeters in diameter. Patients and methods: From March 2023 to December 2023, 70 patients were included in this prospective randomized double-arm interventional study. Patients were divided into two groups: Group 1: (35 patients) had semi-rigid retrograde ureteroscopic laser lithotripsy and group 2: (35 patients) had semi-rigid antegrade ureteroscopic laser lithotripsy.

NCT ID: NCT05218057 Completed - Ureteric Stone Clinical Trials

to Compare the Effectiveness of Thulium Fiber Laser and Holmium YAG Laser for Ureteroscopic Lithotripsy

Start date: May 1, 2022
Phase: N/A
Study type: Interventional

This prospective randomized clinical trial aimed to compare the difference in stone ablation rates of TFL and Ho:YAG laser in a clinical setting. Patients are randomized to receive URS with lithotripsy (URSL) either with TFL or Ho:YAG with an allocation ratio of 1:1. Primary outcome is the efficiency of stone ablation in terms of the stone ablation rate

Semi-rigid Ureteroscopy Versus Flexible Ureteroscopy For the Treatment of Proximal Ureteric Stone

Start date: November 26, 2020
Phase: N/A
Study type: Interventional

The present study is randomized in nature, comparing the stone free rate and complications rate between semi-rigid ureteroscopy (SR-URS) and Flexible Ureteroscopy (F-URS) for the treatment of Proximal Ureteric stone (PUS), whereby the preoperative assessments, procedure and reporting of outcomes will all be standardized.

Comparison of CHOKAI vs STONE Score to Predict the Presence of Ureteric Stones in Patients With Renal Colic: A Multi-center Prospective Observational Study

Start date: February 1, 2021
Phase:
Study type: Observational

Background: The STONE score has traditionally been used as a clinical prediction tool to predict the presence of ureteric stones in patients presenting with renal colic. More recently, the CHOKAI score was introduced and found to have superior diagnostic accuracy on both internal and external validation. Objective: Our study aims to externally validate and compare the use of both the CHOKAI and STONE score in a population of UAE patients presenting to the Emergency Department for renal colic. Methods: Over a period of approximately 6 months, the study will follow Emergency Department Physicians at each institution and retrieve data from their encounters with patients presenting with renal colic. Parameters for both CHOKAI and STONE scores will be logged, extracted and matched against a reference standard of CT scan to compare diagnostic accuracy of both scores to predict the presence of ureteric stones in this population. Goals: Evaluation of the findings will discern applicability of scores to the UAE population and contribute to reducing unnecessary radiation exposure. To our knowledge, no studies have compared the use of these scores to diagnose urolithiasis in the United Arab Emirates. Furthermore, this will be the first study to externally validate the CHOKAI score outside of Japan using a controlled, prospective design.

NCT ID: NCT03795545 Completed - Ureteric Stone Clinical Trials

Ultraslow SWL Versus Slow SWL for Ureteric Stones With High Attenuation Value

ESWL
Start date: January 11, 2019
Phase: N/A
Study type: Interventional

Ultraslow full-power SWL versus slow power-ramping SWL in ureteric stones with high attenuation value

NCT ID: NCT03704623 Completed - Ureteric Stone Clinical Trials

Parecoxib vs Paracetamol in the Treatment of Acute Renal Colic

Start date: May 1, 2019
Phase: Phase 4
Study type: Interventional

This study will be conducted to compare the efficacy and safety of Parecoxib versus Paracetamol for treatment of acute renal colic due to ureteric stones.

NCT ID: NCT03404986 Completed - Ureteric Stone Clinical Trials

Ultrasound Guided Ureteroscopy and Ureteric Stones

Start date: April 1, 2018
Phase: N/A
Study type: Interventional

The prevalence of urolithiasis is steadily increasing with an estimation of 1 out of 11 people in the United States. The prevalence of calculi in Afro-Asian region including Arab Republic of Egypt ranges from 4% to 20%. Ureteroscopy is one of the first line treatments for definitive management of ureteric stones. Conventional ureteroscopy relies on intraoperative fluoroscopy for visualization and guidance, exposing the patient, surgeon and operating room staff to ionizing radiation. To minimize the hazards of ionizing radiation there has been a trend toward radiation free alternative imaging modalities . Ultrasound provides an excellent alternative for upper urinary tract imaging because it is radiation free, rapid, portable and allows excellent visualization of the renal pelvis and calyces. There is increasing awareness and concern about the clinical use of ionizing radiation and the need to decrease exposure of patients and medical professionals. Ultrasound guided ureteroscopy in pregnant females and children- in whom fluoroscopy is to be minimized or avoided when possible - has been reported.

NCT ID: NCT03274700 Not yet recruiting - Ureteric Stone Clinical Trials

The Use of Tamsulosin in Treatment of (10-15 mm) Lower Ureteric Stones in Adults With Non-emergent Symptoms

Start date: October 1, 2017
Phase: Early Phase 1
Study type: Interventional

To estimate the efficacy of tamsulosin in: A - Expulsion of lower ureteric stones from10-15 mm diameters (primary goal). B - Pain relief and hyronephrosis improvement (secondary goal).
