Filter by:there is an increased incidence of renal stones, especially in the pediatric age group. the percutaneous approach in the pediatric age took a long time till it again accepted among surgeons worldwide. the prone position is the preferred approach to perform percutaneous nephrolithotomy in the pediatric age group. this study aims to compare supine versus prone position percutaneous nephrolithotomy in the pediatric age group.
Prospective, monocentric, single arm, observational PMCF - Study on the Performance and Safety of Double-Shank Titanium Ligation Clip in Urology (Prostatectomy and Nephrectomy)
Urolithiasis is a common health problem worldwide affecting approximately 10% of the population at some stage in their lives. The aim of this study is to evaluate the efficacy of adjuvant treatment with tamsulosin for improving the stone-free rate after a single session of extracorporeal shock wave lithotripsy (ESWL) in the treatment of radiopaque kidney stones.
In the present study investigators aimed to investigate whether homeodomain interacting protein kinase 2 (HIPK2) polymorphism is associated with renal stone formation in Turkish population or not. One hundred and twenty nine participants with calcium nephrolithiasis and 67 sex and age-matched healthy controls were enrolled in this study. For analysis of HIPK2 polymorphism, the real-time PCR amplification was performed in a final volume of 20μL reaction mixture, including 10 ng of genomic DNA, 5 µL of TaqMan® Universal PCR Master Mix, and 0.5 µL of 40X TaqMan® assay. The Rotor-Gene Q Series Software Version Q 2.3.1 (Rotor-Gene Q Series, Ziagen) was used for allelic discrimination. Chi square test was utilized to compare the differences of the genotype and allele frequencies between patients and controls.
Percutaneous nephrolithotomy (PCNL) is considered to be the first choice and a more conservative procedure than open stone surgery. Not only postoperative pain related to dilatation of the renal capsule and parenchymal tract, but also patient's discomfort & nephrostomy tube-related stress are reported to delay recovery time and increase the complication rates. This study is designed to provide postoperative analgesia by using ultrasound-guided continuous Quadratus Lumborum Block (QLB) III in patients undergoing PCNL and to assess pain scores & side effects with less opioids consumption.
Given the high recurrence of urolithiasis in patients, the search for less aggressive and preventive treatments is increasingly necessary. Renalof® is presented as an alternative to herbal medicine being a product that, due to its diuretic and demineralization properties of kidney stones, has been widely used in this patient population, disintegrating and eliminating calcium oxalate and struvite stones in a painless in the genitourinary system. With the objective of determining the efficacy of this therapy, an observational, prospective, randomized, single-blind, two-arm study was carried out: treatment group with Renalof® and control group, placebo.
Evaluation of a nonopioid recovery pathway after percutaneous nephrolithotomy is a pragmatic pilot study that will apply the knowledge and experience gained with development of an outpatient opioid reduction protocol to percutaneous nephrolithotomy (PCNL). We have previously demonstrated that outpatient ureteroscopy and stent placement without postoperative opioid prescriptions is possible in the vast majority of patients. The success of this is dependent upon a multimodal approach to the patient's experience of undergoing endoscopic kidney stone surgery (ureteroscopy) and focuses on the preoperative, perioperative, and postoperative stages of intervention. Our hypothesis is that a novel nonopioid pathway after PCNL is both feasible and safe and will reduce postoperative prescriptions for opioids without impacting clinical outcomes, patient satisfaction or outpatient resources.
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.
To analyze and compare the puncture success rate, puncture fluoroscopy time and intraoperative puncture complications of two different puncture techniques; fluoroscopic bi-planar (0-30º) versus newly reported bi-planar (0-90º) technique in PCNL.
Percutaneous nephrolithotomy (PCNL) is a first-line treatment for kidney stones >2cm. Frequently, patients require multiple procedures to address their stone burden. The decision to proceed with a second-look procedure is based on follow-up CT imaging, which is obtained postoperatively. In this study, we propose the use of a portable CT scan technology to obtain follow-up imaging while the patient is still under anesthesia for the initial procedure. The goal of this study is to determine whether this allows the surgeon to identify residual fragments and render the patient stone-free within a single anesthetic event.
