Filter by:The specific aim of this study is to validate our hypothesis that the magnetic ureteral stents have the same amount of adverse effects as the more commonly used non-magnetic ureteral stents. If this hypothesis would be confirmed then the usage of magnetic ureteral stents would be justified for both reducing patient discomfort by way of fewer cystoscopies and possibly also decreasing the overall expenditures of treatment.
A randomized clinical trial to investigate the impact of increased fluid intake and increased urine output on the recurrence rate of urinary stone disease (USD) in adults and children. The primary aim of the trial is to determine whether a multi-component program of behavioral interventions to increase fluid intake will result in reduced risk of stone disease progression over a 2-year period.
compare the outcomes of SWL for renal and upper lumbar ureteric stones using the alternating bidirectional approach versus the standard approach.
This is a single arm, single center study to assess the safety and efficacy of a form of extracorporeal lithotripsy, called the Enhanced Lithotripsy System, to treat urinary stones.
The aim of this study was to evaluate the role of flexible cystoscopy in preventing malpositioning of the ureteral stent after laparoscopic ureterolithotomy in male patients. From April 2009 to June 2015, 97 male patients with stones >1.8 cm in the upper ureter underwent intracorporeal double-J stenting of the ureter after laparoscopic ureterolithotomy performed by four different surgeons. In the last 50 patients who underwent laparoscopic ureterolithotomy flexible cystoscopy was performed through the urethral route to confirm the position of the double-J stent, while in the first 47 correct positioning of the stent was confirmed through postoperative KUB.
Double blinded randomized controlled clinical trial to assess the impact of intraoperative Toradol on post-operative pain scores for patients undergoing ureteroscopy for urinary stone management.
Up-to-date, urology guidelines introduce safety guidewire (SGW) as an integral tool in ureteroscopy and recommended its routine use. However, the necessity of SGW placement in endourological procedures lack evidence and is being suggested as an expert opinion. Present study aimed to evaluate the use of SGW placement and its necessity in treatment of ureteral stones with semi-rigid ureteroscopy (s-URS). For this purpose patients with ureteral stones are being stratified according to ureteral stone location and prospectively randomized into two groups' according to SGW usage or not in s-URS. Ureteroscopy and litotripsy is being done with a semi-rigid ureteroscope of 6.4/7.8 Fr (Olympus) and laser. Chi-square and student t-test were used for comparing data.
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).
The incidence of nephrolithiasis in children has been reported to increase by approximately 6-10% annually, and the incidence is currently 50 per 100,000 children with high recurrent rate. Investigators aimed to determine the metabolic risk factors in Chinese children through metabolic evaluation. In order to identify diagnostic criteria of hypocitraturia and hyperoxaluria in western country wether adapt to Chinese children, investigators aim to determine normal urine levels of oxalate and citrate in children without kidney stone.
Investigators observed that during the Extracorporeal Shock Wave Lithotripsy (ESWL) non-pharmacological methods used for reducing the level of the pain and anxiety among the patients with the urinary stones are not sufficient and the effectiveness of these methods is controversial. There are very few studies, which investigated the effects of music on the pain and anxiety during ESWL. In addition, any randomized clinical trial related to the use of stress ball for relaxation and distraction on the reduction of pain and anxiety during lithotripsy has not been found in the relevant literature. Investigators also evaluated that further evidence-based studies are necessary. Thus, investigators aimed to investigate the effectiveness of stress ball and music for reducing the pain and anxiety of the patients during ESWL in this study.
