Filter by:This is a two arm, double blind RCT comparing the use of a single dose ciprofloxacin prior to SWL to saline alone. The multicenter trial will be conducted with a pragmatic emphasis including both high volume and low volume sites internationally.
The investigators have developed an extremely low dose renal computed tomography (CT) protocol that on preliminary testing has an effective dose in the range of a single view abdominal radiograph. The investigators plan to test this exam in patients with known or suspected urolithiasis undergoing clinically indicated CT.
This a study aiming to compare treatment with tamsulosin versus placebo in patients undergoing endoscopic treatment for urolithiasis. The main outcome is the rate of stone free patients.
The purpose of this research study is to compare how well two treatments work for removing kidney stones. The two study groups include ureteroscopy with long/short pulse lithotripsy to remove kidney stones. Both of these options are considered standard of care and are used currently in surgery.
comparative study of two treatment modalities (ureteroscopy and extracorporeal shock wave lithotripsy) in management of upper third ureteral calculi
The prevalence of urolithiasis is steadily increasing with an estimation of 1 out of 11 people in the United States. The prevalence of calculi in Afro-Asian region including Arab Republic of Egypt ranges from 4% to 20%. Ureteroscopy is one of the first line treatments for definitive management of ureteric stones. Conventional ureteroscopy relies on intraoperative fluoroscopy for visualization and guidance, exposing the patient, surgeon and operating room staff to ionizing radiation. To minimize the hazards of ionizing radiation there has been a trend toward radiation free alternative imaging modalities . Ultrasound provides an excellent alternative for upper urinary tract imaging because it is radiation free, rapid, portable and allows excellent visualization of the renal pelvis and calyces. There is increasing awareness and concern about the clinical use of ionizing radiation and the need to decrease exposure of patients and medical professionals. Ultrasound guided ureteroscopy in pregnant females and children- in whom fluoroscopy is to be minimized or avoided when possible - has been reported.
Double J ureteral stents (DJ) are widely used in urological practice and commonly inserted after most of ureteroscopies. Stent-related symptoms (SRS) represent a major issue. Many research lines have been explored with the aim of decreasing SRS: Vogt et al. projected a self-made pigtail suture stent (PSS) replacing the distal pigtail with a 0.3 Fr suture reaching the bladder, showing decreased SRS and good tolerance. To date, these promising results hasn't been confirmed by a prospective randomized controlled trial (RCT) involving a marketed PSS. Thus, we designed a prospective single-blind RCT to compare SRS caused by marketed PSS and conventional DJ after uncomplicated URS for stone treatment.
Précis: Randomised control trial to evaluate safety and efficacy of intraluminal injection of high pH-high concentration of a long-acting local anesthetic and long-acting glucocorticoid in the ureter after ureteroscopy. Objectives: To evaluate a novel method to ameliorate post-ureteroscopy pain in all patients (with and without stents) Endpoints: Primary endpoint: mean visual analog pain scale (VAS) post-operatively starting at 1 hour, 4 hours, 8 hours, 24 hours and 7 days post-procedure (minimum of 3 VAS scores). VAS pain, ureteral stent symptoms and analgesic requirement will be assessed at different points during this time period. Secondary endpoint: Postoperative Nausea/Vomiting (PONV), safety of intraluminal injection of high concentration alkalinized local anaesthetic solution by comparing adverse events between placebo and treatment arms. In addition, rehospitalisation rates and postoperative length of stay will be compared between the three groups. Population: 150 adult patients undergoing ureteroscopy for ureteric stone disease stratified into negative ureteroscopy and those treated for a stone with or without stent insertion postoperatively Number of Sites: Tallaght Hospital Study Duration: 8 months
To estimate the efficacy of tamsulosin in: A - Expulsion of lower ureteric stones from10-15 mm diameters (primary goal). B - Pain relief and hyronephrosis improvement (secondary goal).
