Low-intensity extracorporeal shockwave therapy for Peyronie's disease: An Indian experience.

Introduction: Efficacy of low-intensity extracorporeal shockwave therapy (LiESWT) in Peyronie's disease (PD) has not been studied in an Indian population. Here, we studied the effect of LiESWT in Indian PD patients.

Methods: This prospective study was conducted on 25 patients who completed weekly sessions of LiESWT for 6 weeks with a follow-up of 6 months. Patients were evaluated using International Index of Erectile Function (IIEF)-5 questionnaire for erectile dysfunction and visual analog scale for pain. Baseline and follow-up examinations included measurement of plaque size and curvature. The primary outcome was to assess remission of pain and reduction of plaque size along with improvement of penile curvature and erectile function as the secondary outcome.

Results: Primary goal of pain reduction and ≥50% reduction of plaque size was achieved in 64% and 20% of patients, respectively. Improvement in vaginal penetration during sexual intercourse and IIEF-5 score increase of ≥3 was achieved 20% and 36% cases, respectively. The mean reduction of penile curvature was more with plaque calcification (PC), but the difference was not statistically significant (P = 0.26). The difference in mean visual analog scale reduction was more in noncalcified plaque (P = 0.002). The mean reduction of plaque size in patients with PC was significant (P = 0.03).

Conclusions: Shockwave therapy is a probable alternative treatment option. A significant improvement was observed in pain and plaque size in patients treated by LiESWT. The presence of PC may affect the outcome of LiESWT in PD.
