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: NCT02734914 Not yet recruiting - Renal Calculi Clinical Trials

Suctioning Flexible Ureteroscopy With Intelligent Control of Renal Pelvic Pressure

Start date: May 2016
Phase: N/A
Study type: Interventional

This study evaluates the safety and efficacy of the suctioning flexible ureteroscopy(SF-URS) with automatic control of renal pelvic pressure for the treatment of upper urinary calculi using a prospective, randomized design. Half of participants will receive suctioning flexible ureteroscopy with automatic control of renal pelvic pressure, while the other half participants will receive retrograde intrarenal surgery using the classic flexible ureteroscopy.

NCT ID: NCT02711670 Completed - Kidney Stones Clinical Trials

Night Time Use of Thiazide Diuretics for Improved Reduction in Stone Risk in Stone Formers With Elevated Urine Calcium

Start date: February 2014
Phase: N/A
Study type: Interventional

Thiazide diuretics will be more effective in lowering urine calcium excretion if taken at night as compared to the daytime. It will therefore be more effective in reducing kidney stone recurrence in nephrolithiasis patients with elevated urine calcium who are known to have increased risk of kidney stones at night time.

NCT ID: NCT02690662 Completed - Obesity Clinical Trials

Influence of Hypocaloric Diet on Urinary Lithogenic Factors of Obese Patients With Kidney Stones

Start date: February 2016
Phase: N/A
Study type: Interventional

The objective of this study is to evaluate the influence of low-calorie diet on serum and urinary metabolic parameters of obese adults with urinary calculi and lithogenic metabolic abnormalities.

NCT ID: NCT02683993 Active, not recruiting - Stone Clearance Clinical Trials

Utilizing Holmium Laser for FURS Renal Stone Lithotripsy Comparing Stone Breaking vs. Stone Dusting Settings

Start date: February 2016
Phase: N/A
Study type: Interventional

Twenty (20) subjects presenting with a renal stone and candidates for FURS (flexible ureteroscopic renal surgery) will undergo a single FURS procedure for a kidney stone as part of the study, using the study device. These subjects will be randomized into stone breaking treatment or stone dusting.

NCT ID: NCT02658942 Completed - Renal Stones Clinical Trials

Flexible Ureteroscopy Versus ESWL in the Management of Lower Calyceal Stones

Start date: May 2010
Phase: N/A
Study type: Interventional

to assess safety, efficacy of Flexible ureteroscopy (FURS) holmium:YAG laser lithotripsy (LL) compared to extracorporeal shockwave lithotripsy (ESWL) in management of lower calyceal stones (LC) stones.

NCT ID: NCT02645708 Recruiting - Renal Calculi Clinical Trials

External Physical Vibration Lithecbole(EPVL) Versus Traditional Row of Stone After Retrograde Intrarenal Surgery(RIRS)

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

The treatment of renal calculus by retrograde intrarenal surgery(RIRS) isn't able to eliminate stone completely, hastening fragments clearance just only rely on traditional expulsive methods such as high fluid intake ,increasing physical activity, medical expulsive therapy and changing body position. Therefore, researchers purpose to evaluate the effectiveness of external physical vibration lithecbole(EPVL) in treatment of residual fragments after RIRS by prospective study of clinical trial, which will improve stone-free rate of residual fragments and benefit more patients.

NCT ID: NCT02645058 Completed - Renal Stones Clinical Trials

RIRS Versus ESWL for the Treatment of Renal Stones

Start date: March 2, 2015
Phase: N/A
Study type: Interventional

To evaluate the effectiveness of RIRS (retrograde intrarenal surgery) and ESWL (extracorporeal shockwaves lithotripsy) in the treatment of renal stone ranging form 6 to 20 mm size.

NCT ID: NCT02643134 Recruiting - Renal Calculi Clinical Trials

External Physical Vibration Lithecbole Versus Traditional Row of Stone After Extracorporeal Shockwave Lithotripsy(ESWL)

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

The traditional stone row method comprises increasing exercise, drink lots of water, drug row of stone and stone row position. External physical vibration lithecbole(EPVL) is a non-invasive device active row of stone, the researchers hope that through this test prospective clinical study to evaluate the effectiveness of in vitro physical vibration row of stones after extracorporeal shockwave lithotripsy(ESWL) treatment of stones discharged, thereby improving after ESWL stone clearance rate.

NCT ID: NCT02635048 Completed - Kidney Calculi Clinical Trials

Mini-PCNL Versus Standard-PCNL For The Management of 20-40 mm Size Kidney Stones

Start date: January 1, 2016
Phase: N/A
Study type: Interventional

Percutaneous nephrolithotomy (PCNL) has been considered as the first-line choice for the management of >20mm kidney stones. The traditional nephrostomy tract of PNL was dilated to 24-30F, which is referred to as "Standard-PCNL". Standard PNL has an ideal stones free rate (SFR), however, at the cost of severe morbidity. To decrease the disadvantages related to standard PNL, "mini-perc" or "mini-PCNL", 20F or less, was first introduced to pediatric procedure in 1997, and subsequently implemented in adults with the expectation of similar SFR and low morbidity in the past twenty years. Although abundant efforts have been done, whether mini-perc outweigh standard-PNL for the treatment of >20mm calculis in terms of efficiency and safety remains controversial. To solve this problem, we performed this multicenter, parallel, open-label randomized controlled trial (RCT).
