NCT ID: NCT03032458 Completed - Analgesia Clinical Trials

Efficacy of Pethidine, Ketorolac And Xylocaine Gel As Analgesics For Pain Control In Shockwave Lithotripsy

Start date: January 2017
Phase: Phase 4
Study type: Interventional

A randomised prospective trial comparing the efficacy of pethidine, Ketorolac, and Xylocaine gel as analgesics for pain control in shockwave lithotripsy.

NCT ID: NCT02983409 Completed - Urinary Calculi Clinical Trials

Analysis the Relationship Between the Abdomen CT and Outcomes in Acute Urinary Stone Patients

Start date: January 2011
Phase: N/A
Study type: Observational

This is an observational study based on retrospectively collected data of ureter stone patients between 2011 and 2014. Aim of study is to determine radiologic findings of non-contrast abdominal computerized tomography as predicting clinical outcomes of suspect ureter stone patients in emergency department (ED).

NCT ID: NCT02895711 Completed - Urolithiasis Clinical Trials

Radiation Dose of Pediatric Patients During Ureteroscopy

Start date: September 2010
Phase:
Study type: Observational

The purpose of this study is to quantify the radiation exposure from diagnostic testing and surgical treatment during routine endourologic procedures for symptomatic urolithiasis.

NCT ID: NCT02875717 Completed - Urolithiasis Clinical Trials

Influence of Acetylsalicylic Acid and Low Molecular Weight Heparins on the Incidence of Renal Hematoma of Shockwave Lithotripsy

Start date: January 2009
Phase: N/A
Study type: Observational

Retrospective Analysis of patients that received shockwave lithotripsy as Treatment of ureteral or kidney Stones. Condition examinated is the effect of low molecular weight Heparins and acetylsalicylic acid on the Formation of renal hematoma after shockwave lithotripsy. Primary outcome is documented hematoma in a postoperative ultrasound control. Secondary outcomes are perioperative complication, Need for erythrocyte tranfusion, interventions for bleeding control, readmission or death within 30 days.

NCT ID: NCT02739919 Completed - Urolithiasis Clinical Trials

Bacterial Analysis of Kidney Stones Removed by Percutaneous Nephrolithotomy

Start date: June 2016
Phase:
Study type: Observational

The aim of this research is to use a controlled laboratory setting to determine whether bacteria isolated from kidney stones of patients play a role in the formation of non-infectious kidney stones. It is well known that struvite stones are associated with active bacterial infection, however the role of bacteria in the formation of non-infection stones (like calcium oxalate) is not well characterized and there are theories that bacteria are involved in the making of these stones.

NCT ID: NCT02539004 Completed - Urolithiasis Clinical Trials

US-Non Contrast Computed Tomography Real-time Fusion for Urinary Stones Follow up

Start date: June 2015
Phase:
Study type: Observational

Urolithiasis is a universal problem, a large part of patients will be affected by multiple stones throughout their lifetime, with estimated recurrence rates of 75% within 20 years. The high recurrence rate requires an increasing amount of imaging follow-up. US-NCCT real-time fusion (Fusion) enables lesion assessment and follow up using both modalities as reference for each other. Our study proposes a novel approach for short term follow up of patients using Fusion instead of repeat NCCT exams. the goal of the study is to create an initial proof of concept that Fusion is effective for follow up of known urinary stones. the study is a prospective study on Patients with an obstructing ureteral stone found on a NCCT. Patients will undergo Fusion (using General Electric Logiq E9) after NCCT. The primary endpoint was the ability to locate the ureteral stone using US with guidance of the NCCT as a "Road Map".

NCT ID: NCT02538016 Completed - Cystinuria Clinical Trials

TCUPS- Tolvaptan Use in Cystinuria and Urolithiasis: A Pilot Study

TCUPS
Start date: October 2016
Phase: N/A
Study type: Interventional

The goal of this research project is to establish that in short-term use, tolvaptan is a safe and potentially effective new therapy for cystinuria, by conducting a short-term pilot study of the safety and tolerability of this drug, and assess impact on urinary stone risk parameters, among adolescent and young adult patients with clinical cystinuria.

NCT ID: NCT02501525 Completed - Urolithiasis Clinical Trials

Effect of Ureteral Access Sheath Use on Postoperative Pain Level in Patients Undergoing RIRS

Start date: August 2015
Phase: N/A
Study type: Interventional

This study will include patients aged between 18 and 70 who will undergo retrograde intrarenal surgery (RIRS) due to renal stone(s). A total of 80 patients (male or female) will be recruited, and will be randomized into 2 groups consisting of 40 patients in each group. The first group of patients will undergo RIRS with a ureteral access sheath (UAS) positioned prior to surgery; and the second group will undergo RIRS without UAS. As use of UAS decreases the pressure in the renal pelvis during RIRS, it is aimed to evaluate whether using UAS or not affects the level of pain felt by patients in the postoperative period.

NCT ID: NCT02485002 Completed - Urolithiasis Clinical Trials

Differences in Urine NGAL Levels in Patients Undergoing RIRS With or Without Ureteral Access Sheath

Start date: June 2015
Phase: N/A
Study type: Interventional

This study will include patients aged between 18 and 65 who will undergo retrograde infrarenal surgery (RIRS) due to renal stone(s). A total of 60 patients (male or female) will be recruited, and will be randomized into 2 groups consisting of 30 patients in each group. The first group of patients will undergo RIRS with a ureteral access sheath (UAS) positioned prior to surgery; and the second group will undergo RIRS without UAS. As use of UAS decreases the pressure in the renal pelvis during RIRS, it is aimed to evaluate whether using UAS or not affects the kidney functions. besides the routine kidney function tests, namely urea and creatinine, neutrophil gelatinase-associated lipocalin (NGAL) (a more specific and early marker of kidney function) will be used to assess the differences in the kidney functions. Preoperative blood urea and creatinine levels and urine NGAL levels will be studied for all patients. After the surgery, blood urea and creatinine levels will be again studied as well as urine NGAL levels at postoperative 2nd hour, 72nd hour and 1st week.

NCT ID: NCT02373384 Completed - Urolithiasis Clinical Trials

The Predictors of Successful Oral Dissolution Therapy in Radiolucent Renal Stones; A Prospective Evaluation

Start date: February 2015
Phase: Phase 4
Study type: Interventional

The aim of the study is to evaluate the predictors of success of oral dissolution therapy in radiolucent renal stones in a large series of patients from a tertiary referral center in order to define the optimum case scenarios where oral dissolution therapy could be implemented.
