Abstract Objectives Fibrosis of the corpora cavernosa follows removal of an infected implant or protracted / recurrent priapism. Penile prosthesis implantation in cases with fibrosis is both difficult and risky. Complications include perforation and/or failure. Shaeer’s Cavernotome (patent application number PCT/EG2021/050003) is a coring / grinding cavernotome that relies on rotational movement without force instead of forward stabbing notorious for complications. Methods Eighteen patients with severe corporal scarring were operated upon. Surgery is performed through a peno-scrotal incision with urethral catheter in place. Two cm long core of fibrous tissue is excised with scalpel, excavating the corporotomies. Shaeer’s Cavernotome (ShC) is lodged-in against the fibrous tissue. Rotational coring is performed proximally and distally with the penis on stretch. ShC doubles as a sizer. Following coring, penile prosthesis implantation proceeds. Results Dilation of the corpora cavernosa was successful up to either girth 11 or 13 Hegar with a single pass, in 17 out of 18 patients. Average coring time was 8 minutes ±3.2. No perforations or infections were encountered Conclusions Shaeer’s Cavernotome facilitates excavation of scarred corporal bodies without forward stabbing, thereby decreasing the difficulty and risk. Conflicts of Interest Author is the inventor of the instrument.
