Nightmares in Salvage Robot-assisted Radical Prostatectomy After Primary Radiation Therapy for Prostate Cancer: A Step by Step Tutorial.

Salvage radical prostatectomy after primary radiotherapy (sRP) is considered a challenging procedure. We highlight the complications of sRP and detail critical surgical steps to help prevent them. A nonsystematic literature review in PubMed using the term "salvage radical prostatectomy" was performed on December 1, 2021. Salvage robot-assisted RP (sRARP) cases and imaging materials were used to create an educational video providing practical examples. Owing to radiation-induced changes in the prostate and surrounding tissues after radiotherapy, sRP is typically more challenging than primary RP. Among its critical steps are incision of the endopelvic fascia, bladder neck dissection with attempts at sparing the neck, development of posterior planes between the prostate and rectum, and dissection of the prostatic apex. Complication rates are significant, in particular for bladder neck contracture (0-16%) and anastomotic leakage (10-33%). Rectal injury is now rare (<2%) but still feared; careful adherence to surgical principles is required to avoid this complication. Functional outcomes are nonoptimal, with a high risk of urinary incontinence (severe incontinence in ∼25% of men). sRARP is a challenging urological procedure and should be performed by experienced surgeons. Thorough knowledge of the surgical anatomy and a meticulous technique for the most difficult surgical steps are crucial to minimise complications and to improve patient outcomes. Patient summary: In patients with prostate cancer, removal of the prostate because of cancer recurrence after primary treatment with radiotherapy can be difficult because of radiation-induced tissue damage. This challenging procedure should be performed by experienced surgeons to minimise the risk of complications.
