What Exactly is Reservoir Herniation?
In a standard 3-piece IPP, the fluid reservoir (the balloon that holds the saline when you are flaccid) is tucked away inside your abdomen. Historically, this was almost always placed in the Space of Retzius (deep behind the pubic bone, near the bladder). Today, especially for guys who have had robotic prostatectomies or pelvic radiation, high-volume surgeons often use Ectopic / Submuscular placement (tucked high up under the abdominal wall muscles but outside the main abdominal cavity).
A herniation occurs when that reservoir slips out of the surgical pocket created by the doctor. Instead of staying hidden and protected, the pressure of your abdomen pushes the reservoir out through the fascial defect (the hole the surgeon made to pass the tubing).
What does it feel/look like?
- You might notice a new, visible bulge in your lower abdomen or groin, especially when you stand up, cough, or strain.
- It might feel like a smooth, semi-firm lump that you can sometimes push back in.
- It can cause groin pain, or a feeling of pressure.
- In some cases, it can cause auto-inflation, because the abdominal muscles are now squeezing the reservoir and pushing fluid down into the cylinders.
The Core Causes of Herniation
Reservoir herniation is relatively rare, especially with high-volume implanters, but when it happens, it usually boils down to a mix of surgical factors and post-op mechanical stress.
1. Surgical & Anatomical Factors
- Fascial Defect Size: To get the reservoir inside, the surgeon has to pierce the transversalis fascia. If this hole is made too large, or if the tissue is weak and tears, the reservoir has an escape route.
- Inadequate Closure: High-volume implanters know they need to tightly close the tissue around the tubing (often called a "purse-string suture") so the tubing can pass but the reservoir cannot. If this isn't secured properly, herniation risk skyrockets.
- Ectopic Placement Nuances: Submuscular placement is fantastic for avoiding bladder/bowel injuries in guys with scarred pelvises, but it inherently places the reservoir in a more shallow muscular plane. If the pocket isn't dissected perfectly, muscle contractions can force the balloon out.
2. Post-Op Mechanical Factors (The "Valsalva" Effect)
Your abdomen is a pressurized cylinder. Any time you bear down, you create a spike in intra-abdominal pressure (the Valsalva maneuver). If you do this before the surgical pocket has had time to heal and form a protective scar-tissue capsule around the reservoir, that pressure will squeeze the reservoir right out of its home.
- Heavy Lifting: Lifting weights, groceries, or children too soon after surgery.
- Straining on the Toilet: Post-op constipation (often caused by opioid painkillers and anesthesia) is the #1 enemy of a new IPP reservoir.
- Severe Coughing/Sneezing: Chronic coughs from COPD, smoking, or catching a cold right after surgery.
Tips for Prevention: Securing Your Reservoir
Preventing this complication requires a team effort between you and your surgeon. Here is the playbook.
Pre-Op & The Surgeon
- Go to a High-Volume Implanter: A surgeon who does 50-100+ of these a year has the muscle memory to size the fascial defect perfectly and stitch it tight. Don't be afraid to ask your surgeon: "What is your protocol for securing the reservoir to prevent herniation?"
- Discuss Reservoir Location: Have a frank discussion about whether the Space of Retzius or Ectopic placement is right for your specific anatomy and surgical history.
Post-Op Care (The First 4-6 Weeks)
The goal here is to let a firm capsule of scar tissue form around the reservoir. Once that capsule forms, herniation is incredibly unlikely.
- Respect the Weight Limit: If the doc says no lifting over 10 lbs for 4 weeks, they mean it. A gallon of milk and a heavy door is your absolute limit.
- Aggressive Bowel Management: Start taking Miralax, Colace, or whatever stool softener your doctor recommends the day you get home. Hydrate constantly. When you sit on the toilet, do not push or strain. Let gravity do the work.
- The Coughing Protocol: If you feel a sneeze or cough coming on, grab a pillow and press it firmly against your lower abdomen/groin. This braces the abdominal wall and counters the pressure spike. If you catch a cold, get on cough suppressants immediately.
- Getting Out of Bed: Do not do a "sit-up" to get out of bed. Roll onto your side, drop your legs over the edge, and use your arms to push your upper body up. Protect your core!
- Wear the Jock/Binder: If your doctor sends you home in a surgical binder or supportive jockstrap, wear it exactly as prescribed. It provides external counter-pressure while you heal.
Bottom Line: Herniations suck, and usually require a brief revision surgery to push the reservoir back in and stitch up the defect. But by choosing a great surgeon and being incredibly disciplined with your core pressure for the first month, you can keep those odds near zero.
