NCT ID: NCT03388060 Completed - Urologic Diseases Clinical Trials

(SWL) Versus (ODT) Versus Combined SWL And ODT For Radiolucent Stone

Start date: April 1, 2017
Phase: N/A
Study type: Interventional

compare the efficacy of of ultrasound guided SWL versus dissolution therapy versus combined SWL and dissolution therapy in management of 1 - 2.5 cm renal stones.

NCT ID: NCT03379922 Completed - Nephrolithiasis Clinical Trials

Strategies to Maximise Patient Comfort During ESWL

Start date: March 27, 2017
Phase: N/A
Study type: Interventional

Extracorporeal shockwave lithotripsy is an outpatient treatment for patients with intrarenal calculi. Standard of care involves offering oral analgesia prior to commencing the treatment. Most patients do not take the offered analgesia after the initial treatment. It has been suggested that distraction techniques may be equivalent to oral analgesia in improving tolerability of extracorporeal shockwave lithotripsy treatment. The use of distraction techniques also removes the potential side effects of mediation administration.

NCT ID: NCT03373617 Completed - Renal Stone Clinical Trials

The Effect of Anesthesia Type on RIRS

Start date: December 13, 2017
Phase:
Study type: Observational [Patient Registry]

Retrograde intrarenal surgery (RIRS) with flexible ureteroscopy is based on video monitoring of urinary tract during operation. Therefore, shaking vision on monitor can bother surgeons and make them tired. This can lead in tissue injury from lasing. The purpose of this study is to investigate the stability of monitoring of surgical field which is assessed by surgeon.

NCT ID: NCT03349099 Completed - Urolithiasis Clinical Trials

Impact Ureteral Sheath Design During Ureteroscopy

Start date: June 27, 2014
Phase: N/A
Study type: Interventional

The purpose of this study is to assess whether one of two ureteral access sheaths is safer for patients undergoing ureteroscopy. Both sheaths are FDA approved devices and commercially available. The investigators will compare the ability of sheaths to access the kidney through the ureter and will compare damage done to the ureter after completion of the procedure. Access sheaths are standard of care for this procedure; this study seeks to optimize outcomes for patients. Patients undergoing ureteroscopy who do not have ureteral stents in place and who have not had an ipsilateral procedure within 90 days will be recruited and consented.

NCT ID: NCT03348228 Completed - Nephrolithiasis Clinical Trials

Effect of Hydroxycitrate on Urine Chemistry

Start date: October 4, 2018
Phase: N/A
Study type: Interventional

Hydroxycitrate (HCA) is a compound extracted from the fruit, Garcinia Cambogia. Hydroxycitrate supplements are available over the counter and are primarily promoted as a weight loss supplement. There has been recent evidence that hydroxycitrate is a potent inhibitor of calcium oxalate crystal growth and can lead to the dissolution of the crystals. The purpose of this research study is to study the effect of Hydroxycitrate (HCA) supplements on HCA urinary excretion and on urine chemistries in kidney stone formers and normal subjects.

NCT ID: NCT03344107 Completed - Pain Clinical Trials

Stent-related Symptoms Comparison: Polaris Loop vs Vortek Double-J Stents

Start date: January 10, 2018
Phase: N/A
Study type: Interventional

Prospective randomized controlled single-blind parallel-group trial in order to compare symptoms related to loop-tail (Polaris Loop) stents versus conventional double J (Vortek) stents after uncomplicated flexible URS.

NCT ID: NCT03332056 Completed - Nephrolithiasis Clinical Trials

The Use of Belladonna and Opium Suppository in the Treatment of Postoperative Stent Pain

B&O
Start date: August 2013
Phase: Phase 4
Study type: Interventional

The purpose of this study is to determine if preemptive B&O suppository placement will decrease post-operative pain in patients undergoing ureteral stent placement.

NCT ID: NCT03318926 Completed - Renal Stone Clinical Trials

Increased Tea Consumption is Associated With a Decreased Risk of Renal Stone Disease in a Taiwanese Population

Start date: June 2001
Phase: N/A
Study type: Observational

The objective of the this study was to examine the amount and duration of tea consumption in relation to the risk of renal stone disease.

NCT ID: NCT03130907 Completed - Ureteroscopy Clinical Trials

The Role of Ureteral Stenting Following Uncomplicated Ureteroscopy for Ureteral and Renal Stones: A Randomized, Controlled Trial

Start date: June 1, 2017
Phase: N/A
Study type: Interventional

It is well established that uncomplicated distal ureteroscopy can be safely performed without leaving a ureteral stent. However, many urologists continue to leave ureteral stents following uncomplicated ureteroscopy, regardless of stone location, due to concerns for post-operative complications, patient symptoms and to reduce unplanned medical visits. There is a paucity of data regarding the utility of stent placement for proximal ureteral or renal stones following ureteroscopy. We have designed a prospective, randomized controlled trial to evaluate the role of ureteral stent placement following ureteroscopy and pyeloscopy in proximal and renal stones.

NCT ID: NCT03112499 Completed - Renal Insufficiency Clinical Trials

The Effect of Three Endourological Procedures for the Management of Renal Calculi Regarding Acute Kidney Injury

Start date: June 5, 2018
Phase: N/A
Study type: Interventional

The main aim of the study is to investigate and compare the possible acute effect of standard PCNL, mini-PCNL and RIRS on renal function. Secondary aims are to investigate the efficacy (stone-free rate), safety (complication rate, long-term kidney function) and other parameters (operation, fluoroscopy and hospitalization time) concerning the 3 endourological operations (PCNL, mini- PCNL, RIRS) for the treatment of renal calculi.
