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.
The EUA Urolithiasis Guidelines Panel meta-analysis suggest that mPNL is at least as efficacious and safe as sPNL for the removal of renal calculi. However, the quality of the evidence was poor, drawn mainly from small studies, the majority of which were single-arm case series, and only one of which was RCT. The risks of bias and confounding were high, highlighting the need for more reliable data from RCTs. So, the Panel recommended for more clinical research . The aim of this study is to compare between PNL and mPNL through a randomized controlled trial.
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.
The purpose of this study is to assess whether certain beverages can increase urinary citrate levels in healthy individuals with no history of kidney disease.
- The primary aim is to study the natural history of single-calyx asymptomatic nonobstructing stone disease. - The Secondary aim is to determine the predictors of the need for intervention and of cure in such population.
A comparison on the outcomes of patients undergoing shockwave lithotripsy using the Storz machine versus the Dornier machine.
Randomized comparison of patient outcomes following standard PCNL versus mini-PCNL.
This study will test whether oxalate stimulates urinary crystals and impacts the immune system in healthy subjects using two controlled diets (low and high oxalate).
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.
To determine if the effects of MOSES laser modulation technology can improve the safety and efficiency to laser fragmentation resulting in decreased total laser time, reduced potential for injury to the patient, and total OR time and utilization.
