Phosphodiesterase type 5 inhibitors do not prevent curvature progression but shorten pain duration in the active phase of Peyronie's Disease: A retrospective cohort study
Abstract
Treatment with Phosphodiesterase Type 5 inhibitors (PDE5is) has shown promise in managing Peyronie’s disease (PD) during its active phase. In a retrospective cohort study of 133 PD patients, we compared daily PDE5i treatment (sildenafil 25 mg or tadalafil 5 mg) in Group 1 (n = 101) to no treatment in Group 2 (n = 32). The mean age ± SD was 58.5 ± 10, (range: 29-77) years in Group 1 and 59 ± 13.7 years (range: 23-80) in Group 2 (p = 0.5). Mean symptom onset-to-visit time was 10.6 ± 7.2 months (range: 1-37) in Group 1 and 11 ± 6.3 months (range 3-27) in Group 2 (p = 0.5). Mean penile curvature change was +0.87° (95% CI: -1.8, 3.5) in Group 1 and +5.72° (95% CI: 1.4, 10) in Group 2 (p = 0.07) between first and last observations. Group 1 experienced shorter mean pain duration (9.1 ± 4.7 months, range: 2.5-24) than Group 2 (12.2 ± 6.5 months, range: 5-28) (p = 0.04). When controlling for baseline curvature and symptom onset-to-visit time, there were no differences between groups (-4.7, 95% CI: -10, 0.6) (p = 0.08). In conclusion, continuous PDE5i treatment did not affect PD curvature progression but showed a promising effect on pain.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 133 participants or records.
