Filter by:The investigators aim to investigate the effect of peritubal local anesthetic infiltration on pain scores and analgesic consumption in patients who underwent percutaneous nephrolithotomy.
Randomized treatment trial of baking soda or LithoLyte to determine if baking soda and Litholyte are effective in raising 24 hour urine citrate and pH.
A comparison on the outcomes of patients undergoing shockwave lithotripsy using the Storz machine versus the Dornier machine.
Patients undergoing retrograde intrarenal surgery for kidney stones from November 2017 to May 2018 were prospectively recruited to participate in the study. In each case after the beginning of general anesthesia with mechanical ventilation surgeons were asked to assess the mobility of the operative field and conditions for laser lithotripsy according to the developed questionnaire scale. The questionnaire consisted of 5 degrees of assessment of kidney mobility and each question was scored from 1 to 5, 1 being very mobile (extremely poor conditions for dusting) and 5 completely immobile (Ideal conditions for dusting). After this assessment modified technique of general anesthesia was applied called combined respiratory support which consisted of reduction of tidal volume to 250-300 ml and respiratory rate to 4-5 per minute with transcatheter high frequency jet ventilation through endotracheal tube with a respiratory cycle frequency of 300 per minute and maintained during retrograde intrarenal surgery. At the beginning of combined respiratory approach, surgeons were once again asked to assess the mobility of the operative field and the conditions for laser lithotripsy. Main ventilation parameters were recorded and compared in both regimens.
Patients with nephrolithiasis and evidence of hypocitraturia or aciduria who would otherwise be started on potassium citrate, can achieve similar urine alkalization with 500-1000 mL of daily low calorie orange juice consumption.
The purpose of this study is to measure how well two different devices work to break up and remove kidney stones. We are comparing a newer device to an older one to see which one is faster at breaking up kidney stones. We hypothesize that the Trilogy will increase the stone clearance rate by 25% compared to the Shockpulse-SE
Patients who underwent retrograde intrarenal surgery (RIRS) were randomly allocated to general anesthesia (GA) or spinal anesthesia (SA) groups. Renal function was assessed using estimated glomerular filtration rate, and relative renal function was evaluated using nuclear medicine tests. Maneuverability and accessibility were evaluated after every surgery. We analyzed the influence of anesthesia methods on surgical outcomes and renal function in retrograde intrarenal surgery in a prospective, randomized controlled study.
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.
A double blind randomized controlled trial designed to compare pain control and safety with ketorolac and oxycodone in the post-operative setting for patients undergoing ureteroscopy for treatment of urinary stones. Patients are followed for five days after their surgery as they record their pain scores, medication utilization, and stent related symptoms.
The purpose of this research study is to compare how well two medications work to control post-operative pain.
