Overview

The objective of this project is to compare the efficacy of hyoscyamine to tamsulosin monotherapy in treating lower urinary tract symptoms in patients with indwelling double-J ureteral stents.

Ureteral stents are routinely used in a variety of urologic conditions. Unfortunately, indwelling ureteral stents commonly cause significant pain and discomfort due to irritation to the urinary system. Many studies have looked at methods to reduce these uncomfortable symptoms ranging from altering stent designs to pharmacologic therapies attempting to alleviate stent-discomfort. However, stent-related discomfort continues to be an issue and is often the cause of their removal earlier than planned. While the efficacy of certain alpha blockers and anticholinergics in treating stent-related symptoms have been studied, the data for the use of hyoscyamine in this setting is lacking. A literature search yielded no studies evaluating the use of hyoscyamine in this setting to date. The investigators hypothesize that hyoscyamine (brand name Levsin) is equivalent to tamsulosin in treating lower urinary tract symptoms in patients with indwelling double-J ureteral stents due to its anticholinergic properties. Furthermore, the investigators hypothesize that patients in the hyoscyamine arm will not require additional pain medications (e.g. Pyridium, narcotics) to help control stent-related discomfort compared to the tamsulosin arm.

Outcomes

Primary Outcomes

Ureteral Stent Symptom Questionnaire Score

To evaluate the efficacy of hyoscyamine compared to tamsulosin in improving the lower urinary tract symptoms of patients with indwelling double-J ureteral stents as assessed by the validated Ureteral Stent Symptom Questionnaire (USSQ).

Time frame: Three Years

Secondary Outcomes

Additional Medication Needed

To determine if there is a difference between the amount of additional medications needed to treat stent related discomfort between patients receiving hyoscyamine versus those that receive tamsulosin

Time frame: Three Years

Factors That Determine if Additional Medication Needed

To determine factors contributing to patients needing additional medication for treatment of stent-related discomfort

Time frame: Three Years
