Active clinical trials for "Ureteral Calculi"

The purpose of this study is to assess if patients treated with silodosin will have a higher spontaneous passage rate of their ureteral stone than those treated with placebo.

This study aims to compare three groups of patients who underwent uncomplicated ureteroscopic lithotripsy (URSL) to evaluate whether stents could be eliminated after the procedure

Tamsulosin (Flowmax)is approved by the FDA for the treatment for enlarged prostate. Several studies regarding the use of Tamsulosin for the treatment of lower kidney stones have been carried out in the non-Emergency Department setting. This study will compare Tamsulosin 0.4 mg with placebo in regards to rate and time of stone passing and will also look at amount of pain. The purpose of this study is to compare the usefulness of Tamsulosin versus placebo on time to stone passage and pain relief in Emergency Department patients with kidney stones.

This study will assess improvement in the percentage of spontaneous stone passage for distal ureteral calculi for alfuzosin compared to placebo, decrease of pain and narcotic/analgesic use associated with stone passage, decrease of the time to spontaneous stone passage, shift in the size distribution of stones passed towards larger sizes.

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.

Patients with a ureteral or kidney stone that causes symptoms, like pain, frequently have small kidney stones that don't cause symptoms. If these small kidney stones are determined to be asymptomatic (not causing any problems or pain), then most urologists will simply remove the symptomatic ureteral stone and leave the additional stones in the kidneys. However, symptomatic kidney stones started as small stones that didn't cause symptoms. This means that the small stones remaining in the patient's kidney may cause problems later. The purpose of our research is to test if removing small stones from the kidney prevents future stone episodes.

One of the most effective strategies to decrease radiation exposure during ureteroscopy is to use low dose. However, the quality of the image obtained is inferior to full dose image. The main concern is to maintain the stone free and complication rate despite the inferior quality of image obtained. Our aim was to evaluate if reducing the dose of fluoroscopy to ¼ instead of full dose would impact in a reduction of total radiation exposure despite a possible increase in fluoroscopy time. Also, if this strategy would impact in operation time, stone free rate and complication rate of unilateral semi-rigid ureteroscopy for ureteral stone treatment due too less than optimal fluoroscopy image. All patients over 18 years old diagnosed with ureteral stone from 5 mm to 20 mm in diameter by CT scan were counseled regarding their treatment options. Patients who failed spontaneous passage or medical treatment or chose endourologic treatment were included in this study. Patients with abnormal urinary anatomy such as horseshoe kidney, pelvic kidney or duplex system were excluded from the study.

The purpose of this trial is to quantify the amount Celebrex, a specific cyclooxygenase-2 (COX-2) inhibitor, when used for the management of acute renal colic for a ureteral stone will: reduce pain medication usage improve the percentage of spontaneous stone passage decrease the time to spontaneous passage, and shift the size distribution of stones passed towards larger sizes

Ureterolithiasis pain is a severe condition for which it takes some 30 minutes for standard treatment to yield maximal pain relief, a period during which the patient suffers severe to intolerable pain. It would thus be valuable to further evaluate sterile water injection as a method for achieving rapid relief for this type of pain.
