Introduction

 

To compare the efficacy of Mirabegron, Propiverine, and Solifenacin versus placebo for treatment of dysuria and storage symptoms during intravesical BCG therapy.

  

Materials and Methods

 

  • This was a blinded, computer-generated randomized controlled trial that involved patients who qualified for intravesical BCG immunotherapy and were classified as intermediate or high-risk for Non-Muscle Invasive Bladder Cancer (NMIBC). 

  • Included in the eligibility criteria were patients suffering from ongoing dysuria and urinary storage issues for at least one month after finishing the initial BCG treatment. 

  • The efficacy of Mirabegron, Propiverine, Solifenacin, and a placebo in alleviating dysuria was assessed using the Visual Analogue Score (VAS). 

  • To evaluate the improvement of storage Lower Urinary Tract Symptoms (LUTS), changes in the Overactive Bladder Symptom Score (OABSS), along with the changes in Maximum Urine Flow Rate(Qmax) and Post-Void Residual Volume(PVR) were analyzed at a three-month follow-up.

 

Results

 

  • 95 patients fulfilled the inclusion criteria and were allocated in the following categories:

  • Mirabegron- 20 patients

  • Propiverine- 21 patients

  • Solifenacin- 21 patients

  • Placebo- 22 patients

  • Comparisons between pairs indicated a notable decrease in the VAS for both Propiverine and Mirabegron in comparison to Solifenacin and the placebo(p = 0.001). There was no significant difference between Propiverine and Mirabegron (p = 0.9) or between Solifenacin and placebo (p = 0.8). 

  • No significant changes were observed in Qmax or PVR across all groups (p = 0.4 and p = 0.9, respectively).

Conclusion

Propiverine and mirabegron provide comparable, efficient and successful management of dysuria and other BCG cystitis-related urinary symptoms. solifenacin provides no significant value over placebo.
