Filter by:To determine the optimal time between the first and second operations in patients with bilateral kidney stones and scheduled percutaneous nephrolithotomy for the contralateral kidney. Patients who underwent percutaneous nephrolithotomy to the contralateral kidney 2-4 weeks and 4-6 weeks after the first operation will be compared.
The aim of this study is to prospectively analyze patient satisfaction, pain, delivered energy and clinical effectiveness of using VR as a complimentary treatment modality during SWL.
To evaluate the efficacy and stone free rate of placebo versus tamsulosin as medical expulsive therapy post-SWL in patients with renal stone less than 20 mm
Renal stones are one of the most common urological problems and there are multiple methods for their management such as percutaneous nephrolithotomy, mini and ultra-mini percutaneous nephrolithotomy, flexible ureteroscopy and laser lithotripsy, and extracorporeal shock wave lithotripsy. percutaneous nephrolithotomy is the treatment of choice for the management of renal calculi, in spite of the increasing stone clearance rate, the complication rate of this procedure is relatively higher.
The current study is designed to assess the efficacy of a single shot ESPB with Dexmedetomidineversus continuous ESPB in perioperative analgesia for PCNL. Both techniques are conducted for patients undergoing PCNL under GA.
To investigate the effectiveness of percutaneous nephrostomy catheter placement versus retrograde double J catheter placement in patients with symptoms of obstructive kidney disease (with either infection and/or pain and/or kidney function deterioration) caused by urolithiasis.
Background: Standard-PCNL was considered as the first choice for ≥2 cm renal stones. Miniaturized technique Mini-PCNL has also been implicated in the past two decades. Recently, Super-mini PCNL (SMP) was introduced to treated ≤2.5cm renal stone. The miniaturized techniques seemed to take a longer operating time and have risk of getting infectious complications. However, there is no high quality of evidence showing that which kind of PCNL is best or what kind of patients is suitable for standard-PCNL, mini-PCNL or SMP. Objective: To compare the efficacy and safety of Standard-PCNL (≥24Fr), Mini-PCNL (12-20Fr) and SMP(10-14Fr) for the treatment of ≥2 cm renal stones Study design: This study is a prospective, observational, international, multicenter registry cohort study Study population: All patients ≥14 years with ≥2 cm renal stone who are planned for Standard-PCNL, Mini-PCNL or SMP are eligible for this study.
Background: The exit strategy after ureteroscopy for stone treatment remains a topic for discussion. Current EAU guidelines on urolithiasis state that postoperative stenting is indicated in patients at increased risk of postoperative complications. Stenting is not considered necessary in all other cases, and after uncomplicated procedures. Objective: To analyse the postoperative ureteral stenting strategy in clinical practice looking at the indication, type of stents used and the duration of stenting after ureteroscopy for stone treatment. Furthermore, the investigators will examine in what setting the stents are being removed postoperatively. Study design: This study is a prospective, observational, international, multicentre registry study executed by uCARE. Study population: All patients >18 years with a ureter or renal stone who are planned for ureteroscopic treatment by semi-rigid and/or flexible ureteroscopy are eligible for this study.
compare the efficacy of of ultrasound guided SWL versus dissolution therapy versus combined SWL and dissolution therapy in management of 1 - 2.5 cm renal stones.
