Objective: Recent scientific studies have shown different mechanisms for Low Intensity Shock Wave Therapy (LISWT) in treating Erectile Dysfunction (ED): mechanical effect, vasculogenic effect, neurogenic effect, and stem cells stimulation and proliferation; all mediated through different growth factors: TGF-D1, BDNF, VEGF, and nitric oxide. The role of BDNF (Brain-Derived Neurotrophic factor) in promoting Cavernous Nerve regeneration in rats via SC-dependent Janus kinase (JAK)/signal transducer and activator of transcription (JAK/STAT) pathways led us to question and test the role of LISWT in improving the male genitoperineal sensation and  Neurogenic ED in diabetic and neurogenic patients.

Material and Method: A 48 year old man known to have syringomyelia disease (fig1.A.B), dyslipidemia, hypertension, and diabetes; with history of bilateral lower extremities paresthesia since the age of 32, perineal and genital numbness since the age of 29, was presented with severe numbness and mild to moderate ED. Patient received six weekly sessions of linear low intensity shock wave therapy (PiezoWave2 from Richard WOLF) with an energy flux density of 0.16mj/mm2 and frequency set to 8 Hz, wave focus penetration depth set to 10mm. Patient received 6000shocks/session, 2000 shocks on the perineum (1000 each crus penis), 2000 shocks on dorsum penis, 2000 shocks on lateral aspect of penis (1000 each side) (fig2.A.B). The IIEF-5 score and percentage of improvement of numbness (subjective improvement of the touch sensation) in the genitoperineal were documented during each session, after 1 month, 3 months, and 8 months of receiving LISWT.

Results: The IIEF-5 score before and after the treatment were respectively documented: 14 and 18. The percentage of improvement of numbness in the genitoperineal area during each session, after 1 month, 3 months, and 8 months of receiving LISWT were respectively documented: 0% (first session); 20% (second session); 35% (third session); 45%(fourth session); 55% (fifth session); 70% (sixth session); 87% (after 1 month); 87% (after 3 months); 87% (after 8 months) (table1)

 Conclusion: LISWT might improve the male genitoperineal sensation and ED in diabetic and neuogenic patient. Randomized studies based on objective sensation tests are needed to further evaluate the effect of LISWT for such indication.
