Evaluation of Tamsulosin in the Treatment of Ureteral Stones - Full Text View

ClinicalTrials.gov Identifier:	NCT00151567

Purpose

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.

Spontaneous stone elimination rate [ Time Frame: days 1, 7, 14, 21, 28, 35, and 42 ] [ Designated as safety issue: No ]
Spontaneous stone elimination rate, according to stone size (2-3 mm, 4-5 mm, 6-7 mm) [ Time Frame: days 1, 7, 14, 21, 28, 35, and 42 ] [ Designated as safety issue: No ]
Rate of need for surgery [ Time Frame: Within 42 days ] [ Designated as safety issue: No ]
Time to surgery in days in patients with surgical elimination [ Time Frame: between day 1 and day 42 ] [ Designated as safety issue: No ]
Rate of pain recurrences [ Time Frame: within 42 days ] [ Designated as safety issue: No ]

Arms	Assigned Interventions
Experimental: 1 Tamsulosin	Drug: Tamsulosin Oral tamsulosin once a day until stone elimination or the end of the follow-up (42 days)
Placebo Comparator: 2 Placebo	Drug: Placebo Oral placebo of tamsulosin once a day until stone elimination or the end of the follow-up (42 days)

Detailed Description:

Ureteral colic, mainly due to ureterolithiasis, represents 1 to 2% of hospital emergency admissions. When a surgical intervention is not required, usual treatment combines hydration and anti-inflammatory drugs.

Alpha1-blockers, firstly developed as anti-hypertensive drugs, are now also used in the management of benign prostatic hyperplasia, due to their relaxing properties on the urinary tract. The aim of the study is to investigate whether tamsulosin could lower the delay of elimination of the stone in patients with pelvis ureterolithiasis. Patients are randomized to receive either tamsulosin or a placebo in addition to usual treatment until stone elimination. Efficacy is assessed by evaluating the time to spontaneous passage of the stone between day 1 and day 42, the need for surgery and pain recurrences.
