Background And Objectives: In patients with inguinal hernias who have undergone radical prostatectomy, dissecting the medial preperitoneal space is difficult because of the presence of fibrotic scars. It is also difficult to guarantee sufficient space for mesh implantation. We added laparoscopic iliopubic tract repair (IPTR) to transabdominal preperitoneal (TAPP) hernioplasty, and evaluated this for the treatment of inguinal hernias after radical prostatectomy.

We examined which part of the GSV is the most sensitive and dilated in association with venous reflux.
