NCT ID: NCT04169165 Not yet recruiting - Nephrolithiasis Clinical Trials

Patient Compliance for Metabolic Evaluation and Medical Management in Calcium Stone Patients

Start date: January 2020
Phase:
Study type: Observational [Patient Registry]

Calcium oxalate stone, the most common type worldwide, has a recurrence rate of around 50% in ten years. Therefore, identifying the underlying pathophysiological aspects via metabolic evaluation and suggestions for medical & dietary prophylaxis in calcium stone patients is of upmost importance. However, one of the greatest problem with metabolic evaluation and subsequent therapeutic advices is the patient compliance. Therefore, it is important to identify factors related to patient compliance for metabolic evaluation and medical & dietary prophylaxis in calcium stone patients

NCT ID: NCT04157452 Completed - Sepsis Clinical Trials

Prediction of Sepsis After Flexible Ureteroscopy

Start date: June 1, 2019
Phase:
Study type: Observational

Sepsis is a lethal complication of flexible ureteroscopy. The aim of this study is to identify predictors of sepsis after flexible ureteroscopy in patients with solitary proximal ureteral stones.

NCT ID: NCT04153474 Active, not recruiting - Pain Clinical Trials

Exit Strategy After Percutaneous Nephrolithotomy: Large or Small Bore Tube?

Start date: May 1, 2019
Phase: N/A
Study type: Interventional

Regarding to the distribution of nephrostomy tube (NT) size usage by country. There was a clear distinction between countries that used solely the small bore (SB) NT (Chile and Australia) and those that used solely the large bore (LB) NT (Czech Republic and Japan). There is also a trend toward SB NT in North America (~75% in USA and Canada) and toward LB NT in South America (~80% in Argentina and Mexico). In Europe the trend is equal (~50% in Germany, France, Greece and UK). Based on previous data and in view of conflicting data about postoperative complication including extravasation, bleeding and hemoglobin change and pain between previous studies, we will conduct this randomised trial comparing SB and LB NT following PNL. Our aim to evaluate the safety of small versus large bore NT reporting complications using the Clavien-Dindo system with categorisation of PNL-specific complications

NCT ID: NCT04153461 Active, not recruiting - Urolithiasis Clinical Trials

Mini- Percutaneous Nephrolithotomy Versus Standard Percutaneous Nephrolithotomy in the Treatment of Renal Stones.

Start date: May 1, 2019
Phase: N/A
Study type: Interventional

The EUA Urolithiasis Guidelines Panel meta-analysis suggest that mPNL is at least as efficacious and safe as sPNL for the removal of renal calculi. However, the quality of the evidence was poor, drawn mainly from small studies, the majority of which were single-arm case series, and only one of which was RCT. The risks of bias and confounding were high, highlighting the need for more reliable data from RCTs. So, the Panel recommended for more clinical research . The aim of this study is to compare between PNL and mPNL through a randomized controlled trial.

NCT ID: NCT04112160 Completed - Pain Clinical Trials

Prospective Randomized Controlled Trial for Pain Relief After Office Ureteral Stent Removal

Start date: June 28, 2018
Phase: Phase 2
Study type: Interventional

This is a prospective randomized double-blind controlled trial assessing the benefits of intramuscular ketorolac before or immediately after office ureteral stent removal.

NCT ID: NCT04110574 Not yet recruiting - Urinary Calculi Clinical Trials

Computed Tomography Evaluation of Urinary Stones Densities Compared to in Vitro Analysis of Its Chemical Composition

Start date: March 30, 2020
Phase:
Study type: Observational

The ability to predict stone composition, which influences patient treatment, depends on the accurate measurement of CT attenuation of stones. We will study the effects of stone composition, stone size, and scan collimation width on the measurement of attenuation in vitro.

NCT ID: NCT04080973 Not yet recruiting - Osteopenia Clinical Trials

Metabolic Workup in Patients Suffering From Kidney Stone Disease and Osteopenia

Start date: October 2019
Phase: N/A
Study type: Interventional

Patients suffering from acute renal colic are evaluated by non contrast computerized tomography with excellent identification rates of urinary stones. The scan also covers the bones of the ribs, spine and pelvis, allowing measurements of the bone density and identifying early osteopenic changes. Bone demineralization is associated with metabolic changes such as hypercalcemia or hypercalcuria. In this study the investigators will look for correlation between kidney stones, osteopenic bone changes and metabolic abnormalities.

NCT ID: NCT04073719 Not yet recruiting - Clinical trials for Kidney Stones, Urolithiasis, Hypocitraturia

Apple Cider Vinegar for the Prevention of Urinary Lithiasis (APUL)

APUL
Start date: September 1, 2019
Phase: N/A
Study type: Interventional

The purpose of this study is to assess whether certain beverages can increase urinary citrate levels in healthy individuals with no history of kidney disease.

NCT ID: NCT04069338 Completed - Urolithiasis Clinical Trials

Comparison of Lithotripsy Urolithiasis Machines

CoLUM
Start date: May 31, 2019
Phase: N/A
Study type: Interventional

A comparison on the outcomes of patients undergoing shockwave lithotripsy using the Storz machine versus the Dornier machine.

NCT ID: NCT04069013 Recruiting - Kidney Diseases Clinical Trials

Standard vs Mini-PCNL for the Treatment of Stone Disease

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

Randomized comparison of patient outcomes following standard PCNL versus mini-PCNL.
