Filter by:The primary purpose of this study was to compare the effects of erector spinal plane block (ESP) and IV patient-controlled analgesia (PCA) performed to provide analgesia in percutaneous nephrolithotomy surgeries on visual analog skala (VAS), additional analgesia need, patient satisfaction and mobilization times.
The purpose of this study is to collect descriptive performance data using the MONARCH Platform, Urology (a novel robotic device) to perform mini-percutaneous nephrolithotomy (kidney stone removal) procedures. Data gathered from this study will be used to optimize the robotic platform and inform training and education material for the future users.
This is a randomized prospective study to compare stone free rates and operative efficiency of two laser systems used during retrograde intrarenal surgery for kidney stone disease: 1. A superpulsed thulium fiber laser (thulium) 2. A pulse modulated high power holmium laser (Holmium)
Extracorporeal shock wave lithotripsy (ESWL) is the least invasive and effective treatment for upper ureteric stones with a stone clearance rate of 60-90%. Tamsulosin is an alpha-blocker widely used in urological practice to relax smooth muscle of the prostate and bladder neck. Its role as part of medical expulsion therapy for the treatment of patients with kidney and ureteric stones has proved to be of considerable success. However, its role in clearing upper ureteric stones as an adjunct to ESWL is controversial. Therefore, this study will be conducted to evaluate its role in stone clearance along with extracorporeal shock wave lithotripsy in patients with upper ureteric stones
Due to the anatomic characteristics of the lower calyx, lower pole stones are difficult to be eliminated through the ureter, even if the stones had been fragmented. Retrograde intrarenal surgery (RIRS) can be used to deal with lower pole stones of 1.0-2.0 cm, while percutaneous nephrolithotripsy (PCNL) is mainly used to deal with lower pole stones with larger diameter or when RIRS failed to resolve the stone. This study was conducted to compare mini PCNL and retrograde intrarenal surgery (RIRS) for the management of lower pole kidney stones in terms of efficacy.
Nephrolithiasis is the third most common disease of the urinary tract. As minimally invasive technologies develop, shock wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS), and percutaneous nephrolithotomy (PCNL) are different surgeries to treat renal stones. Aim of the Study is to compare results, safety and outcome of Ultra mini PCNL versus stented extracorporeal shock wave lithotripsy (SWL) for the management of renal calculi from 10 - 20 mm. Patients were randomized to either Ultra-Mini-Percutaneous nephrolithotomy group or stented SWL group via the closed envelope method. Patient data was collected preoperatively, immediately postoperatively and 2 and 4 weeks postoperatively to assess operative time, hospital stay, complications regarding fever, hematuria and need for blood transfusion, residual stones and need for retreatment.
This study is designed to provide an evaluation of currently available disposable flexible ureteroscopes in real-world conditions. Due to high re-processing costs associated with re-usable flexible ureteroscopes, there has been a demand for Urologic device manufacturers to provide single-use flexible ureteroscopes.
To compare the efficacy of ultrasound-guided erector spinae plane block versus ultrasound-guided paravertebral block in pediatric patients undergoing percutaneous nephrolithotomy
The extracorporeal shock wave lithotripsy (ESWL) is the treatment of choice for most stones in any of their locations. It is about breaking the stone without surgically intervening on the patient and getting him to expel the fragments himself. It is thought that additional treatments to the ESWL could improve the success rate of ESWL for less favorable stones. The components of our authorized food supplement have shown an inhibitory effect in vitro on the growth of calcium oxalate monohydrate crystals, even in hightly supersaturared solutions. Also these components show an inhibitory effect on the growth of calcium phosphate crystals. To sum up, it reduces the formation, inhibits the growth and promotes the dissolution of calcium oxalate and calcium phosphate kidney stones. This is the reason why this experimental study aims to modify the size limit of the stones in the ESWL with adjuvant food supplement.
We believe that kidney donors with kidney stones accepted for a donation do not have an increased risk of loss of kidney function and will not be at increased risk of symptomatic kidney stone events compared to donors without a history of kidney stones.
