Types of nephrostomy bags
Nephrostomy bags are integral medical apparatuses that hold renal or kidney drainage tubes inserted directly into the pelvis of one or both kidneys through the skin. There are several types of nephrostomy bags, including:
Drainage bags
This bag helps the physician clearly see the output and assist in monitoring changes in a patient's health condition. The drainage bags are transparent culture bags with volume measurements. This bag also has a shut-off valve to avoid backflows. This facilitates easy drainage through a drainage tap. However, many healthcare facilities apply closed systems and do not detach the drainage bag until the nephrostomy tube is changed.
Collecting bags
As the name implies, these bags are solely used for urine collection. Unlike drainage bags, collection bags do not have measuring capacity. They are usually opaque, and an opaque appearance makes it impossible to see the contents through the bag. These bags are often used in home-care situations where patients and families are in charge of care, or healthcare-specific items are not required. They are often rotated with drainage bags, sometimes separately shared, as in situations where it is necessary to measure urine output but not consistent with medical interpretation.
Night bags
These bags have higher volume and can hold urine for several hours' worth of output. They also come with an extension leg clamped and a longer drain tube with a tiny soft suction cup. Night bags are comfortably attached over the leg and discreetly hidden, helping a person continue with dignity even when the bag is full. Most are designed with a draining tap so the bag can be separated from the tube without spillage.
Some bags also feature a sterile valve that seals off the nephrostomy tube, preventing effluent from leaking once the collecting bag is stopped. This facilitates easy carrying of the patient without fear of spillage, even when the bag is fully collected.
Materials & Durability of nephrostomy bags
Nephrostomy bags are made from highly durable materials. Here's a breakdown:
- PVC: Polyvinyl chloride (PVC) is a highly durable material that can withstand exposure to medical-grade disinfectants. PVC is recyclable, contributing to environmental sustainability. PVC nephrostomy bags are flexible and tear-resistant, making them comfortable for patients.
- Polycarbonate: Nephrostomy bags with polycarbonate tubing are impact-resistant and can withstand high temperatures. Polycarbonates provide excellent clarity, allowing easy visual assessment of the bag's contents. The strength of polycarbonate materials makes them suitable for applications that require durability and top performance.
- Elastomers: Medical-grade silicone elastomers ensure prolonged contact with the patient's skin is safe. Silicone elastomers' flexibility and adaptability make them fit for diverse medical uses, including nephrostomy bags. Silicone is environmentally friendly since it is recyclable.
- Polyethylene: Polyethylene film is highly resistant to chemical agents, guaranteeing the integrity of the bag in various settings. It also is lightweight and highly resilient, contributing to user comfort and ease of handling.
- Vinyl: Vinyl is a versatile thermoplastic that contains polyvinyl chloride (or PVC), a durable and flexible synthetic plastic made for heavy-duty uses in producing nephrostomy bags. Vinyl can be recycled as part of the makers' environmental consideration.
- Steel Reinforcement: Steel reinforcement provides exceptional strength and rigidity to the structure of the nephrostomy bags. Steel reinforcement can withstand harsh conditions, including high temperatures and aggressive substances. The long lifespan of any equipment is crucial in medical and industrial settings, ensuring reliability and safety.
Nephrostomy bags are made with skin-friendly adhesives to ensure secure attachment with minimal irritation. This comfort is particularly important for patients needing long-term nephrostomy care.
Scenarios & Expiration for nephrostomy bags
- Renal obstruction treatment: nephrostomy bags are used to manage hydronephrosis or kidney swelling from fluid buildup due to suture obstruction. The tube drains urine, relieving pressure and preventing kidney damage.
- Post-surgical drainage: in kidney tumor removals or transplant surgeries, nephrostomy bags help drain accumulated fluids and prevent infection.
- Infection management: for patients with pyonephrosis or kidney infections, nephrostomy bags facilitate drainage of infected fluid, aiding healing.
- Ureteral obstruction relief: conditions like uretal stones or cancer can obstruct urine flow. Nephrostomy bags provide a way to relieve the obstruction and prevent bladder overdistention.
- Congenital condition management: congenital abnormalities like horseshoe kidney or cystic kidney disease can cause obstruction or fluid buildup. Nephrostomy bags are temporary or long-term solutions to manage these.
- Antibiotic or other medication infusion: nephrostomy bags can be used to infuse antibiotics directly into the kidney to treat severe infections or administer other medications.
- Diagnostic purposes: doctors assess kidney function, urine composition, or kidney-related issues with nephrostomy bags and attached tubing.
- Nephrostomy switch: palliative care uses nephrostomy bags to enhance the quality of life for patients with end-stage kidney disease, allowing for pain-free urine drainage.
Expiration guidelines for nephrostomy bags
The expiration date of a nephrostomy bag varies by manufacturer and type. Several factors influence how long it will last, including the materials used to manufacture the bag, frequency of use, exposure to the elements, and environmental conditions.
- Wear and tear: after frequent handling, spillage risks increase as the bag may develop leaks or weak points. Prolonged use may lead to tube blockages, affecting kidney function.
- Hygiene concerns: bacterially contaminated bags pose infection risks, leading to severe health complications.
- Changes in urine pH and composition can negatively affect the bag material, causing beads or chemical reactions that could result in a bag failure.
For these reasons, monitoring nephrostomy bags for issues often facilitates timely exchanges, reduces risk, and meets medical needs.
How to choose nephrostomy bags
- Comfort and skin-friendliness: nephrostomy bags must have padding and soft-touch, hypoallergenic adhesives that do not harm the skin, especially for patients with a sensitive touch or irritated skin.
- Patient mobility: consider lightweight bags designed for active patients. Mobility could be a factor for patients who need to move around often.
- Bag size and capacity: larger bags with more substantial capacity are preferable for patients with higher output needs. Even so, optimum size should be considered for patients' comfort and discretion.
- Drainage features: choose bags with easy and hygienic drainage systems to avoid spillage and contamination. Some bags have tap systems that facilitate the emptying of the bag without detaching it from the tube.
- Accurate measurements: measurement-transparent bags allow healthcare providers to monitor the urine output of patients effectively, which is vital for assessing patients' health conditions.
- Odor control and ventilation: choose products with effective odor control technologies and ventilated features.
- Ease of attachment and detachment: correctly choosing a nephrostomy bag will ensure simple attachment and detachment from the tubes to facilitate straightforward changing and upkeep.
- Compatibility with existing systems: ensure the chosen bag is suitable for the current nephrostomy tube or other renal equipment.
- Cost and reimbursement options: nephrostomy bags often come in varying cost levels. Choose one that fits the budget without sacrificing quality. Also, check for any insurance or Medicare coverage that might assist with the product's purchase.
