Active clinical trials for "Calculi"

Around 10-18% of patients undergoing cholecystectomy for gallstones have common bile duct (CBD) stones. Currently, various procedures for the treatment of cholecystocholedocholithiasis are available including open cholecystectomy plus open common bile duct exploration (OC+OCBDE), laparoscopic cholecystectomy plus laparoscopic common bile duct exploration (LC+LCBDE), may be trans-cystic or trans-choledochal, and laparoscopic cholecystectomy plus endoscopic retrograde cholangiopancreatography (LC+ERCP), which may be performed pre, at, or after LC.

Evaluation of the best line of treatment of borderline CBD stones associated with gallbladder stones whether by conservative treatment or endoscopic stone extraction as regard complete clearance rate of the CBD stones followed by laparoscopic cholecystectomy. The secondary outcomes are overall complications related to each approach, technical difficulties and conversion rate during laparoscopic cholecystectomy and cost benefit relationship of each line of treatment.

The aim of this study is to identify the root cause for the significant discolouration of Boston Scientific Percuflex based stents.

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.

The purpose of this study is to determine whether continuous intravenous ketorolac infusion reduces pain in patients who are having percutaneous nephrolithotomy for kidney stone disease.

The patient will be asked to participate in a research project designed to determine the best way to prevent bleeding and promote patient comfort after having kidney stones removed. Two standard methods for ending the surgery are being compared to a newer method. In one standard method, the patient will have a tube draining urine from the kidney after the procedure. This tube may also prevent bleeding from the kidney. In another standard method the patient will have a tube left internally that drains urine from the kidney to the bladder and a stitch will be used to close the incision and deeper tissues in the back. In the third potential option, a tube would be left internally to drain urine from the kidney to the patient's bladder and the surgical site would be filled with a clot promoting agent (FloSeal) which is a FDA approved agent specifically formulated to stop bleeding during surgical procedures.

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.

Prospective randomized controlled single-blind parallel-group trial in order to compare symptoms related to loop-tail (Polaris Loop) stents versus conventional double J (Vortek) stents after uncomplicated flexible URS.

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.

In this clinical study, it was aimed to evaluate whether there is a decrease in patient anxiety by applying virtual reality glasses, which are the product of new technology, during scaling and root planing treatment. Patients who required scaling and root planing treatment and also scored 9 or above according to the Dental Anxiety Scale were included in our study. Scaling and root planing was performed in a randomly selected intraoral quadrant of the patients, in the same way, with or without the use of virtual reality glasses. In the virtual reality glasses application, a video consisting of images of nature landscapes developed for patient rehabilitation was projected onto the screen in front of the patient's eyes. The Dental Anxiety Scale was reapplied after the completion of the treatment. In the intraoral quadrant where virtual reality glasses were used, it is expected that lower Corah Dental Anxiety Scale scores may be obtained after the treatment is completed, compared to the intraoral quadrant where the treatment is performed without glasses, thus reducing anxiety.
