From the Guidelines
For women with urinary retention, alpha-blockers like tamsulosin or alfuzosin are preferable due to their efficacy in relaxing the smooth muscle at the bladder neck and urethra, thus facilitating urination. When considering the management of urinary retention in women, it's crucial to evaluate the underlying cause, which could range from anatomical obstruction to neurological issues or side effects from other medications. The use of alpha-blockers, such as tamsulosin or alfuzosin, is supported by guidelines that suggest their effectiveness in patients with urinary retention, as indicated by the expert opinion in the AUA guideline on management of benign prostatic hyperplasia 1. Key points to consider in the management of urinary retention in women include:
- The choice of medication should be based on the underlying cause of retention.
- Techniques like double voiding and timed voiding can be beneficial.
- Addressing contributing factors such as constipation or discontinuing medications that may exacerbate retention is crucial.
- If medication does not provide relief within a reasonable timeframe, or if retention is severe, further medical evaluation is necessary to consider interventions like catheterization. Given the information available and prioritizing morbidity, mortality, and quality of life, alpha-blockers emerge as a preferred initial treatment option for women with urinary retention, provided there are no contraindications such as a history of alpha-blocker side effects or unstable medical comorbidities 1.

From the Research
Medication Options for Urinary Retention in Women
- The provided studies do not directly address urinary retention in women, but rather focus on overactive bladder symptoms.
- However, some medications mentioned in the studies, such as tolterodine, may be used to treat urinary retention in women.
Comparison of Medications
- Tolterodine is compared to oxybutynin in several studies, with tolterodine showing similar efficacy but a lower incidence of dry mouth 2, 3, 4.
- Solifenacin is compared to tolterodine, with solifenacin showing better efficacy but a similar incidence of dry mouth 4.
- Fesoterodine is compared to extended-release tolterodine, with fesoterodine showing superior efficacy but a higher risk of withdrawal due to adverse events and dry mouth 4.
Dosage and Formulation
- The standard recommended starting dose of tolterodine is 2 mg twice daily, but a 1 mg twice daily dose may be equally effective with less risk of dry mouth 4.
- Extended-release preparations of oxybutynin and tolterodine may have less risk of dry mouth compared to immediate-release preparations 4.
- Solifenacin 5 mg once daily is the usual starting dose, but may be increased to 10 mg once daily for better efficacy but with increased risk of dry mouth 4.
Safety and Efficacy
- Tolterodine has been shown to be well-tolerated and effective in treating overactive bladder symptoms in women, with a low incidence of serious adverse events 2, 3, 5.
- The safety profile of tolterodine is similar in patients aged 65 years and older compared to younger adults 2.
- Combination therapy of tolterodine and an alpha-blocker may be more efficacious than monotherapy, with a good safety profile 6.
