- The therapeutic effects of tadalafil (Cialis) for bladder outlet obstruction (BOO) can be predicted based on pretreatment total testosterone (TT) level.
Why this matters
- This finding could help clinicians selecting a therapeutic strategy for patients with lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH).
- Researchers studied outpatients with LUTS due to BOO, treating them with 5 mg tadalafil daily for 12 months (n=69; mean age, 69.8 years; mean prostate volume, 48.8 mL).
- They then separated patients into good and poor responders, based on improvements in BOO index (BOOI).
- Funding: None disclosed.
- After 12 months, mean BOOI in good responders (30 patients or 43.5%) improved from 71.8 to 39.3 (P<.001>
- Mean BOOI in poor responders (39 patients or 56.5%) only changed from 70.6 to 64.3 (P=.25).
- Pretreatment TT was the only independent predictor related to improvements in BOO (R=0.33; P=.003).
- The study was single-center and open-label, with a small sample size.
