Filter by: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.
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.
Sepsis is a lethal complication of flexible ureteroscopy. The aim of this study is to identify predictors of sepsis after flexible ureteroscopy in patients with solitary proximal ureteral stones.
This is a prospective randomized double-blind controlled trial assessing the benefits of intramuscular ketorolac before or immediately after office ureteral stent removal.
A comparison on the outcomes of patients undergoing shockwave lithotripsy using the Storz machine versus the Dornier machine.
The investigators propose a pilot clinical trial on the use of perioperative pregabalin in order to decrease ureteral stent related symptoms and decrease opioid usage after ureteroscopy with stent placement. Patients undergoing ureteroscopy with stent placement will receive a single dose of 300 mg pregabalin PO in the preoperative area. This work will assess safety and feasibility of studying this regimen at our institution, with the aim of performing a randomized, placebo-controlled, double-blinded study in the future.
The purpose of this study is to determine the rate of absorption of fluids (water or saline) during ureteroscopy and to assess the effects on electrolyte levels. The investigators also want to measure how much better the urologist can see the ureter based on the type of irrigation fluid that is used.
The purpose of this study is to examine the feasibility of using sipIT tools (i.e., wrist-worn sensors, smart water bottles, mobile applications) to increase compliance with physician-recommended fluid consumption guidelines in participants with a history of urolithiasis. The study aims to: 1) deliver notifications regarding fluid consumption to the FitBit Versa and the participant's smartphone based on the participant's assessed fluid intake, and 2) determine the acceptability of using the sipIT tools to increase fluid consumption. It is hypothesized that receiving notifications regarding fluid consumption will lead to an increased compliance in attaining fluid consumption guidelines. Further, it is hypothesized that the frequency of notifications will diminish across the study duration.
