Filter by:It is aimed to evaluate the treatment results, rates of success and complications, and injury given to the kidney by measuring preoperative and postoperative blood and Cystatin C levels in patients with kidney stones smaller than 2 cm who will undergo either ultra-mini percutaneous nephrolithotripsy (PCNL) or micro PCNL.
To compare the safety and Efficiency of 20w 30w holmium laser device in treatment of 1-2 cm diameter kidney stones with Retrograde Intrarenal Surgery (RIRS).
To compare safety and efficiency of 20w 30w holmium laser device in treatment of 2-3 cm diameter kidney stones with Retrograde Intrarenal Surgery (RIRS).
We want to serach the relationship between the pain degree and stone localisation in kidney in Retrograde intrarenal surgery
Purpose: to investigate the postoperative outcomes of Retrograde intrarenal surgery versus percutaneous nephrolithotomy in 2 to 4 cm kidney stones.
The aim of this research is to determine an effective antibiotic regimen following definitive surgical therapy of kidney stones caused by bacterial infection (struvite stones).
The purpose of this study is to compare the postoperative systemic inflammatory response syndrome (SIRS) rates undergoing retrograde intrarenal surgery (RIRS) after multiple-, single-, zero-dose of ceftriaxone prophylaxis in a prospective randomized trail. The investigators will enroll 450 patients who are candidates for RIRS in the investigators study. By simple random sampling technique, patients will be assigned to three groups (multiple-, single-, zero-dose of ceftriaxone prophylaxis,respectively). In addition to the difference of usage of ciprofloxacin prophylaxis, the rest of the procedure is the same in all three groups.The end point of the study is the comparison of outcome of procedure including SIRS rate, stone free rate (SFR), operation time, length of stay,and hematuresis.
A prospective study comparing different laser settings used for stone fragmentation during ureteroscopy
The SKSC is a continuous database with the objective of a standardized diagnosis and monitoring of patients with kidney stones as well as the establishment of a Biobank.
Hospitalization for kidney stones in the Inflammatory Bowel Disease (IBD) population is common, particularly among Crohn's patients who had a small bowel resection. This patient population experiences a lifetime occurrence of kidney stone formation as high as 25% accompanied with a high rate of recurrence (the typical rate of stone formation is ~10% in the non IBD population). Giving oral calcium is used to bind oxalate in the intestine in an attempt to reduce the amount of oxalate that is absorbed into the body and to reduce urinary oxalate levels. However, there are no defined guidelines for the optimum dosing of calcium. This study's primary objective is to scientifically define an appropriate range of calcium supplementation that reduce the level of oxalate found in the urine of patients living with inflammatory bowel disease.
