Abstract
Abstract Introduction Severe corporeal fibrosis presents significant challenges in penile implant insertion. LISWT studies in rats and humans have suggested its ability to rejuvenate cavernous bodies through various mechanisms and growth factors. Objective This prompted our evaluation of LISWT's effectiveness in facilitating prosthesis implantation in patients with penile fibrosis, which are typically considered difficult cases. Methods A 34-year-old male smoker with a history of sickle cell disease, bilateral hip replacements, and splenectomy due to sickle cell crisis sought penile prosthesis implantation. He presented with severe erectile dysfunction and corporeal fibrosis following two ischemic priapism episodes caused by sickle cell disease, which were treated with distal shunts 4 and 1 years prior, respectively (Fig. 1). After obtaining consent, the patient underwent four cycles of LISWT, spaced one month apart. Each cycle consisted of four weekly sessions using the PiezoWave2 device from Richard WOLF with settings of 0.16mj/mm2 energy flux density, 6Hz frequency, and 10mm wave focus penetration depth. In each session, the patient received a total of 6000 shocks, distributed between the perineum, dorsum penis, and the lateral aspect of the penis. Results A month post-LISWT, the patient's Erection Hardness Score (EHS) improved from 0 to 1 following an intracavernous injection of 20 mcg of alprostadil (Fig. 2). Subsequently, he underwent a malleable penile implant procedure through the penoscrotal approach. Cavernosal dilation was successful up to 10mm using a Hegar dilator, with bilateral corporal measurements of 8cm proximally and 9cm distally. A Tactra malleable penile prosthesis (9.5mm girth and 17cm length) from Boston Scientific was implanted without complications (Fig. 3.A.B) Conclusions In cases of severe corporeal fibrosis, pre-treatment with LISWT may aid in the dilation of the corpora during penile prosthesis implantation, potentially reducing complications. Randomized studies are warranted to validate this indication Disclosure No.
