Part 2 – What Happens When I Have Prostate Surgery? 

As with other pelvic surgeries such as hernia repairs or hysterectomies, radical prostatectomies can be performed with a laparoscopic technique or with an open incision. Most laparoscopic prostatectomies are now performed in a robotic-assisted technique where several small incisions are made. Then, long robotic arms are inserted through these openings in the abdomen to complete the procedure. If an open procedure is chosen, it can be performed via a retropubic approach with an incision from the umbilicus to the pubic bone. Less commonly, open prostatectomies are performed with a perineal incision. A perineal approach can lead to a shorter recovery time, but this method does not allow for lymph node removal if the cancer has spread into the pelvic lymphatic system. Patients also have a greater chance of developing erectile dysfunction with the perineal approach. There is currently no difference in surgical outcomes when comparing urinary continence and erectile dysfunction after open and robot-assisted laparoscopic methods.1

Recovery time, blood loss and pain levels, however, are lower with laparoscopic methods. Younger age at time of surgery and the experience of the surgeon, regardless of surgical approach, are correlated to increased speed of recovery and fewer long-term issues with sexual function or continence as well. Unfortunately, even with the increasing popularity of robotic approaches, post-surgical urinary incontinence rates are still around 80%.2

While the term prostatectomy denotes that the prostate is removed, other local anatomical structures are also impacted. Seminal vesicles and surrounding lymph nodes can be resected depending on the extent of neoplasm growth. The seminal vesicles and prostate create the majority of fluids released during ejaculation, so post-operative orgasms can still be pleasurable but will be “dry.” The vas deferens are also dissected during a radical prostatectomy. Recall that these structures transport sperm from the testicles to the urethra, and consequently, postoperative infertility occurs. In addition, the cutting and subsequent shortening of the urethra can decrease penile length. Other possible side effects include increased risk of erectile dysfunction: the prostatic nerve plexus, a branch of inferior hypogastric plexus off the hypogastric nerve, surrounds the prostate. The plexus is involved in erection, which is almost always difficult after surgery. Normally, erectile function improves. However, lingering issue may be due to damage of this innervating structure.3 

Post-operatively, a 1- or 2-night hospital stay is standard, and catheterization is common for 7-14 days after the surgery. Pain medication and antibiotics are frequently prescribed during this period. Activities such as golf, calisthenics, and weightlifting are advised against for the first 2 months as tissues which are cut heal from the procedure, and urine leakage is common during the first few weeks. Leakage generally gradually decreases over the first year of recovery; consequently, adult diapers or pads are commonly required during this time while the continence is regained. Pelvic floor physical therapy can help with persistent, unresolved leakage.4

One of the greatest structural impacts to urinary continence is the loss of the prostatic urethra with its associated smooth muscle: a shortened residual urethra means there is less surface area left for the pelvic floor muscles to compress to prevent leaking. The striated urethral sphincter (external urethral sphincter) can also be impacted by the surgery. This muscle generates the greatest urethral pressure of all the striated pelvic floor muscles. Urinary continence can only be maintained when the pressure in the urethra exceeds that of the bladder. As a result, damage to the striated urethral sphincter can be particularly problematic, especially when intra abdominal pressure is increased during movement or coughing.5
