In patients with penile prosthesis, any transurethral procedure could place the implant at risk. The use of long or extra-long resectoscope can be of some assistance; however, these are not available in many institutions. So suprapubic transvesical endoscopic prostatectomy is newly developed to bypass the anterior urethra. Thus, the aim of this study is to determine safety and efficacy of Suprapubic Transvesical endoscopic prostatectomy.
