Filter by:A comparison on the outcomes of patients undergoing shockwave lithotripsy using the Storz machine versus the Dornier machine.
Patients included in the study included the necessary tests U / A, K, Na, Cr, BUN, CBC, And U / C was checked and anesthesia counseling was done. Patients were prepared for action. The demographic and clinical data of the patients, including age, sex, size, and location of the stones were recorded. Then patients as random allocation were divided into two groups: A (control group, no basket of bases and group B (use of pneumatic synchronous buccal waist). The dividing person and the patients themselves were not aware of which group they were in. They were double-blind was. In each group, ureteroscopy was performed using a standard F9.5 ureteroscope. After reaching the rock in group A (control), the probe of the pneumatic crusher was passed through the working channel of the ureteroscope and began crushing the rock. During the crushing process, the minimum flow of water, flattening and the single-shot impact was used to minimize the stone's retropulsion. In group B (using a basket of wires3F) the helical type was passed through the four wires of the working channel of the ureteroscope and routed to the proximal part of the rock, and the stone was routed to the bowl, then the stone was ducted The gasket was kept, and the probe of the pneumatic crusher also passed through the working channel and proceeded to break it down. Conditions were observed during the stomach as the control group. Ureteroscopic crushing was performed by a urologist in both groups under similar technical conditions. Findings during and after the completion of crushing include the success, stone retropulsion or parts larger than 3 mm, which requires secondary measures (SWL - ureter stenting, resection ureteroscopy), the duration of stone breakdown and traumatic ureteric complications in both groups it is registered.
A double blind randomized controlled trial designed to compare pain control and safety with ketorolac and oxycodone in the post-operative setting for patients undergoing ureteroscopy for treatment of urinary stones. Patients are followed for five days after their surgery as they record their pain scores, medication utilization, and stent related symptoms.
Ultraslow full-power SWL versus slow power-ramping SWL in ureteric stones with high attenuation value
The purpose of this study is to compare ureteroscopy with and without use of safety guide-wire in treatment of ureteral stone
This study will be conducted to compare the efficacy and safety of Parecoxib versus Paracetamol for treatment of acute renal colic due to ureteric stones.
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.
The aim of this study was to evaluate the role of flexible cystoscopy in preventing malpositioning of the ureteral stent after laparoscopic ureterolithotomy in male patients. From April 2009 to June 2015, 97 male patients with stones >1.8 cm in the upper ureter underwent intracorporeal double-J stenting of the ureter after laparoscopic ureterolithotomy performed by four different surgeons. In the last 50 patients who underwent laparoscopic ureterolithotomy flexible cystoscopy was performed through the urethral route to confirm the position of the double-J stent, while in the first 47 correct positioning of the stent was confirmed through postoperative KUB.
