  Purpose

The purpose of this study is to determine whether combination therapy with Tolterodine ER and Tamsulosin is more effective than monotherapy with tamsulosin alone in reducing stent symptoms.

The investigators hope to show that the addition of Tolterodine ER to Tamsulosin will provided added benefits in reducing stent symptoms in patients who have had unilateral placement of a ureteral stent.

The investigators hypothesize that combination therapy with tamsulosin and tolterodine ER will yield greater symptom relief than tamsulosin alone.

Arms Assigned Interventions
Active Comparator: Tamsulosin plus placebo
Tamsulosin is a selective α1a-blocker (FlomaxTM), generic since 2009. It is an antagonist of α1-mediated contraction of prostate, bladder and proximal urethral smooth muscle, and as such, reduces urethral pressure and resistance, bladder outlet resistance, bladder hyperactivity, and consequently lower urinary tract symptoms.
Drug: Tamsulosin
0.4 mg by mouth once per day.
Other Name: Flomax (TM)
Experimental: Tamsulosin plus Tolterodine ER

Tolterodine ER is an anticholinergic agent, which is used as one of the first line agents for detrusor overactivity.

Drug: Tamsulosin

Other Name: Flomax (TM)
Drug: Tolterodine ER
4 mg by mouth once a day.
Other Name: Detrol (TM)

Detailed Description:

The investigators aim to show that the addition of Tolterodine ER to Tamsulosin will provide added benefits in ameliorating stent related symptoms in patients who have had unilateral placement of a ureteral stent for urolithiasis. This objective will be assessed by determining the mean difference in the urinary symptom index domain of the Urinary Stent Symptom Questionnaire, which is a validated tool used to assess stent symptoms1. The investigators felt that a 15% further decrease in the index score in the experimental group, compared to the control group would represent a clinically significant improvement in urinary symptoms, based on the prior studies evaluating lower urinary tract symptoms in patients with stents. The investigators hypothesize that combination therapy with Tamsulosin and Tolterodine ER will yield greater symptom relief than tamsulosin alone.
