What Are the Disadvantages of a Suprapubic Catheter?

A suprapubic catheter (SPC) is a tube placed directly into the bladder through a small incision in the lower abdomen to drain urine. This method is often chosen for long-term bladder drainage when the urethra cannot be used. The use of an SPC introduces drawbacks, ranging from immediate procedural risks to chronic health complications and significant lifestyle impacts. Understanding these negative consequences is essential.

Immediate Risks of Catheter Placement

The initial placement of an SPC is a surgical procedure that carries acute, though relatively infrequent, risks. While the overall complication rate is generally low, the severity of potential complications can be high. A primary concern is damage to surrounding organs, particularly the bowel, which can be injured if the bladder is not adequately distended before insertion. Bowel perforation is a rare but serious complication. The procedure also carries a risk of bleeding and hematoma formation at the insertion site. Patients on anticoagulant therapy face an elevated risk of prolonged bleeding. Furthermore, incorrect placement, such as inflating the catheter balloon outside of the bladder, can cause significant trauma to the abdominal tract.

Common Clinical Health Complications

Once the SPC is in place, the high likelihood of developing catheter-associated urinary tract infections (CAUTIs) is a major disadvantage. All indwelling catheters become colonized with bacteria, which often progresses to symptomatic infection, resulting in recurrent UTIs for many long-term users. Another frequent problem is catheter blockage, which occurs when urine sediment, crystals, or mucus accumulates within the tube. Blockages are a major cause of emergency department visits for SPC users. The presence of the foreign body in the bladder also promotes the formation of bladder stones (calculi), a common issue with long-term catheter use. Patients often experience painful bladder spasms, which are involuntary contractions of the bladder muscle triggered by the catheter’s presence and irritation. These spasms can be severe and may cause urine leaking around the catheter. The irritation caused by the catheter may also lead to symptoms that mimic a urinary tract infection, complicating diagnosis and management.

Managing the Stoma Site and Leakage

The site where the catheter enters the abdomen, known as the stoma, presents localized issues requiring constant management. Persistent drainage or discharge around the exit site is a common complaint, which can lead to skin breakdown and local infection, such as cellulitis. The presence of the tube can also stimulate the growth of excessive tissue, known as granulation tissue, which can narrow the tract and make future catheter changes difficult or painful. Urine leakage around the catheter, or bypassing, is a challenging complication. This leakage can be caused by catheter blockage, bladder spasms, or the tract widening over time. Managing this leakage often necessitates frequent dressing changes and can lead to odor, which significantly impacts a person’s social comfort and hygiene. If the leakage is persistent and severe, it can cause maceration of the skin and predispose the area to chronic inflammation and infection. In some cases, the catheter tract can be lost entirely, requiring a difficult or complicated re-insertion procedure. The ongoing need for supplies and meticulous hygiene to manage the stoma and prevent these complications adds a considerable burden to the patient or their caregiver.

Impact on Daily Activities and Lifestyle

Living with an SPC imposes restrictions and psychological burdens that diminish quality of life. The need to manage drainage bags and secure the catheter can limit clothing choices and interfere with physical activities, such as contact sports or swimming. The constant presence of the device requires a shift in self-image and can cause psychological distress. Sexual intimacy can also be affected, despite the catheter not passing through the urethra. The presence of the tube and the need to manage the drainage system can introduce self-consciousness and practical difficulties. For those requiring long-term care, the device places a significant maintenance burden on caregivers, who must manage supplies, hygiene, and frequent troubleshooting. The chronic nature of these issues means constantly prioritizing catheter care over other aspects of daily life.
