Active clinical trials for "Ureteral Calculi"

Ultraslow full-power SWL versus slow power-ramping SWL in ureteric stones with high attenuation value

to compare efficacy and safety of Silodosin and Tamsulosin in Medical expulsive therapy of Distal Ureteric Calculi.

Extracorporeal shock wave lithotripsy (ESWL) is the least invasive and effective treatment for upper ureteric stones with a stone clearance rate of 60-90%. Tamsulosin is an alpha-blocker widely used in urological practice to relax smooth muscle of the prostate and bladder neck. Its role as part of medical expulsion therapy for the treatment of patients with kidney and ureteric stones has proved to be of considerable success. However, its role in clearing upper ureteric stones as an adjunct to ESWL is controversial. Therefore, this study will be conducted to evaluate its role in stone clearance along with extracorporeal shock wave lithotripsy in patients with upper ureteric stones

The aim of this prospective comparative clinical study to compare DJ stenting and Sildosin after ureteroscopic lithotripsy for lower ureteric stones.

The study will be a prospective randomized double-blind placebo-controlled trial of mirabegron for medical expulsive therapy (MET) in patients with a CT (Computed Tomography) scan-proven ureteral stone between 4 to 10 mm undergoing expectant management.

Ureteral stones have an important place in daily urological practice, usually causing acute episodes of ureteral colic by obstructing the urinary tract. The aim of the study is to evaluate whether repeated administration of tamsulosin, a drug routinely used in the treatment of lower urinary tract symptoms, could lower the delay of elimination of the stone in patients with pelvis ureterolithiasis.

Kidney stones are very common, and can inflict a significant degree of pain and renal damage. Some stones become obstructed in the ureter, the tube that drains the kidney. In order to remove these stones, an Urologist and their team use fluoroscopic guidance to do so, this involves continuous X-ray. Flouroscopy delivers a significant dose of radiation to the patient, as well as the health care team, which has been shown to have serious health consequences. Previous studies have shown that in certain populations, like pregnant women, stones can be managed using ultrasound guidance. The investigators propose that mid and distal ureteral stones could be managed using ultrasound guidance in conjunction with conventional stone removal techniques (ureteroscopy, lithotripsy, and ureteral stent placement), in lieu of fluoroscopy, thereby minimizing radiation to healthcare staff and patients. The investigators hypothesize that distal ureteral stones can be identified and efficiently fragmented and removed under ultrasound guidance in a safe and effective manner without the use of radiation.

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.

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.

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.
