Filter by: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.
Background: Many studies showed that stone-free rates (SFRs) after extracorporeal shock wave lithotripsy (SWL) might be related to both the patient (body mass index; BMI, skin-to-stone distance; SSD), and stone related factors (location, stone size, and stone density). However, the possible effect of pre-stenting on success as well as complication rates after SWL has not been evaluated in detail to date. Taking this fact into account, the effect of pre-stenting on the outcomes of SWL treatment in renal stones must be evaluated in the absence of possible effects induced by the patient and stone-related factors. Aim: To evaluate the effect of double J (JJ) stents on SWL treatment of moderate sized (15-25-mm) renal pelvic stones. Study design: Randomized prospective study Methods: Between January 2016 and December 2017, a total of 152 adult patients who were planned to undergo SWL for a single radiopaque renal pelvic stone were included in the study. Patients with solitary kidney, congenital abnormality, skeletal tract abnormalities, previous urinary system surgery, hydronephrosis (grade 2 or more), untreated urinary tract infection, bleeding disorder, and suspected pregnancy were excluded. The remaining 114 patients were randomly divided into two groups; nonstented and stented. Twenty-two patients whose stone could not be fragmented despite 3 consecutive sessions were also excluded from the study. A total of 92 patients (54 non-stented and 38 stented) were included in the final analysis.
