Brief Summary:
To determine if emergency department patients with acute ureteral colic pain due to a ureteral stone who are treated with tamsulosin, versus placebo, will experience a shorter time to passage of their stone or resolution of their pain. A secondary study objective will be to determine if there is a relationship between response to tamsulosin and stone size or position in the ureter.

Detailed Description:

This is a prospective randomized placebo controlled study of tamsulosin alone, vs placebo, to determine its effect on the rates of stone passage and resolution of pain in patients with acute renal colic pain that present to the emergency department. The study will be conducted in the Emergency Department (ED)and Emergency Department Observation Unit (EDOU) of William Beaumont Hospital, a high volume, university affiliated 952 bed suburban teaching hospital.

Patients will be given a seven-day supply of tamsulosin (0.4mg daily) or placebo. They will also be given a prescription for Vicodin (30 pills) and Ibuprofen (600mg, 30 pills). They will be called on days 1, 2, 3, 7, and 10 following the index visit regarding passage of stone or 48 hours without pain. Patients will be asked to call in if they pass their stone or are without pain for 48 hours. Related return visits to Royal Oak or Troy Beaumont within 30 days of their index visit will be followed by chart review.

The study will be limited to patients presenting to the emergency department with acutely symptomatic renal colic pain. Confirmation of a symptomatic stone will be made by imaging (helical CT scan or intravenous pyelogram).

Study exclusion criteria:

  • Stone not documented on imaging
  • Stones >10mm
  • Pregnancy
  • Age <18 years
  • Evidence of infection with an obstructing stone
  • Obstructing stone in a solitary kidney
  • Currently taking tamsulosin, vardenafil, nifedipine, or steroids
  • Contraindications or allergy to tamsulosin
  • Ureteral surgery
  • Patients that are unable to understand consent
  • Patients that are unable to comply with follow-up

Primary Outcome Measures :
  1. Stone Passage [ Time Frame: 1-7 days ]
    Participants were asked during the follow-up phone call to indicate if their stone had passed within seven days. Phone calls were conducted at days 1, 2, 3, 7, 10 and 30 days after the emergency department discharge. Data is reported based on the information obtained up to the 7th day.


Secondary Outcome Measures :
  1. Amount (Mean Number of Tablets Taken) of Pain Medication Taken by Subjects up to Seven (7) Days Post Emergency Department Discharge [ Time Frame: 1-7 days ]
  2. High Pain Score by Treatment Group [ Time Frame: 7 Days ]
    Severity of Patient Pain at 7 days Post Emergency Department Visit. Patients were asked to describe their pain severity at each followup phone call, using a numerical scale, ranging from 0 (no pain) to 10 (worst possible pain). We report this measure at 7 days.
