Filter by:This multi-center trial is being completed to compare patient outcomes related to the Imajin silicone stent in comparison to non-silicone polyurethane stents after ureteroscopy. Eligible participants will be enrolled and randomly assigned to receive the Imajin silicone stent or a non-silicone stent. In addition, the participants will complete questionnaires and have follow-up information collected (approximately 60 days after surgery). The trial hypothesizes that a ureteral stent made of silicone, will have superior outcomes when compared to non-silicone stents.
Nowadays, Percutaneous Nephrolithotomy (PCNL) has been the surgical procedure of choice for renal stones larger than 2cm or staghorn stones. Yet, the associated postoperative pain is a major drawback. The regional anesthetic management of pain in PCNL operation has been of great concern. The introduction of ultrasound guided erector spinae plane block and paravertebral plane block has been under great focus regarding the efficacy of postoperative pain management. Paravertebral plane block (PVB) is a regional nerve block technique that depends on local anesthetic injection adjacent to the vertebra to block spinal nerve roots in a dermatomal distribution. Erector spinae plane block (ESPB) is a newer regional anesthesia technique that depends on injecting local anesthetic (LA) in a plane between the transverse process and erector spinae muscle. The LA diffuses into the paravertebral space and spreads on both rami (dorsal and ventral) of spinal nerves through spaces between adjoining vertebrae. The aim of this study is to compare the effect of ultrasound guided Paravertebral blockade versus Erector spinae blockade on postoperative opioid use as well as postoperative pain control in patients undergoing unilateral PCNL.
Holmium laser is the current gold standard for lithotripsy on urinary lithiasis, while Thulium is brand new. The latter has been released in July 2020 in Europe, and only in-vitro studies have been published. The aim of this study is to compare the stone free rate in ureteroscopy, for all consecutive patients treated with laser fragmentation, between both Holmium and Thulium lasers. The costs and complications will also be studied.
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.
The optimal management of medium-sized renal stones remains quite challenging and continues to be contested. In the present study, the investigators will compare mini-PNL, RIRS and SWL in the treatment of non- lower pole, medium size, high dense renal stones regarding the stone-free rate, the safety of the procedures, cost, and patients' and surgeon's satisfaction. Eligible patients will be randomly allocated into three equal groups (mini-PNL, RIRS, and SWL). Postoperative, patients will be followed-up by regularly for 3 months. The study parameters will be compared between groups.
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.
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.
This study aims to compare the narrow focus (F1) versus the wide focus (F3) in terms of the efficacy of Shock Wave Lithotripsy (SWL) in the management of renal calculi 1-2 cm and their injurious effect on the kidney.
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.
The purpose of the study is to compare the effects, good and/or bad, of a treatment for removing kidney stones called the SURE procedure for stone evacuation to the standard treatment using a basket for stone removal.
