Filter by:Urolithiasis has an increasing incidence and prevalence worldwide, and some patients may have multiple recurrences. Because these stone-related episodes may lead to multiple diagnostic examinations requiring ionizing radiation, urolithiasis is a natural target for dose reduction efforts. Abdominopelvic low dose CT, which has the highest sensitivity and specificity among available imaging modalities, is the most appropriate diagnostic exam for this pathology. The main objective of this study is to evaluate the diagnostic performance of ultra-low dose CT using deep learning-based reconstruction in urolithiasis patients.
The purpose of this study was to explore the effects of uric acid control on stone recurrence and renal function in patients with calculi of hyperuricemia through a prospective controlled study.
The purpose of this study is to determine if CBD oil has any effect on decreasing postoperative pain control following ureteroscopy for urinary stone disease, and to determine if CBD oil has any effect in decreasing the amount of postoperative opioids (commonly used drug) used by patients after undergoing ureteroscopy for urinary stone disease.
The aim of this study is to evaluate if music listening relieves pain and discomfort during Extracorporeal Shock-Waves Lithotripsy (ESWL).
Despite the advent of treating stones with Extracorporeal Shock Wave Lithotripsy (ESWL) and Percutaneous nephrolithotomy (PCNL), the recurrence rate for renal stones remains high and this may be due to poor compliance of patients with dietary and fluid advice, age, metabolic abnormalities, medicines and the formation of "new stones" from clinically insignificant residual fragments (CIRF). Though some patients become stone-free after ESWL/PCNL or open surgeries, the majority develop "new stones" and it is difficult to predict when these stones will recur until either they have imaging perform or they developed symptoms. However, the use of regular imaging for monitoring will be costly and involve radiation exposure. Therefore, a diagnostic tool is needed to enable the clinician and/or patient to monitor for stone recurrence. In the previous studies, some urine markers were identified that are related to stone formation. The relationship of these urine markers with the recurrence of renal stone will be further explore in this study. Also, potential markers that could predict stone recurrence will be identified, and hence earlier intervention could be offered to patients.
The authors hypothesize that the RIRS using 150-microm Tm-fiber laser is superior than fiber with larger diameters, as 200-microm Tm-fiber laser or 200-microm holmium fiber laser, in such points as follows: - decreasing surgery time and laser-on time due to possibility of 4.3 fold ablation efficacy increase, which has been shown by Andreeva et al.; - increasing the flexible ureteroscope tip deflection lower pole stones availability; - decreased risk of complications and a better irrigation and visualization due to better irrigation with smaller fiber; - increasing of lithotripsy efficacy and laser beam density by lowering of beam focal spot due to using of lesser fiber diameter
We aim to determine the preoperative predictors of sepsis after percutaneous nephrolithotomy (PCNL) in patients with unilateral, solitary and proximal ureteral stones.
The aim of this study is to evaluate if music listening relieves pain and discomfort during Extracorporeal Shock-Waves Lithotripsy (ESWL).
Obstructing urolithiasis can be life-threatening in the setting of urinary tract infection. The purpose of this study is to identify and validate risk factors and markers for the presence of infection and development of sepsis among patients with obstructing urolithiasis.
The aim of this study is to estimate the role of Parents' Health-Education Handbook in preventing pediatric urolithiasis. This study is designed as an unmatched clusters randomized intervention trial. A total of 171 villages and communities in Shufu Count in Kashgar Region of China are assigned to intervention group or control group by a simple random sampling technique with a rate of 1:1. Newborns and their parents are assigned to intervention group or control group as their villages or communities. And at least 2314 newborns are needed in this study. Participants include newborns and their parents. The baseline of newborns includes demographic data, blood cell analysis, urinary tract ultrasonographic examination. Newborns' parents will be asked to answer a questionnaire which regarding the knowledge, attitudes, and practices (KAP questionnaire, estimated by scores) related to pediatric stone. Parents in intervention group will undergo and active health education by the investigator with " Parents' Health-Education Handbook", while parents in control group are without the program. Newborns are invited to undergo blood cell analysis, urine analysis and urinary tract ultrasonographic examination separately when they are one, two and three years old. Their parents will be asked to answer the same KAP questionnaire at the same time. The incidence of urolithiasis is evaluated and compared between the two groups. Improvement of knowledge, attitudes, and practices (KAP questionnaire) related to pediatric stone of parents are evaluated. Association between urolithiasis incidence and improvement of scores in KAP questionnaire are evaluated.
