A cystostomy is a surgical opening made through the lower abdominal wall directly into the urinary bladder, typically to allow urine to drain when the normal route through the urethra is blocked, damaged, or unusable. The procedure has been part of urological practice for over a century, and a catheter placed through this opening is called a suprapubic catheter because it enters the body just above the pubic bone. The reasons someone might need one range from emergency trauma to long-term management of a bladder that no longer empties on its own, and the choice between a cystostomy and other drainage options involves trade-offs that are worth understanding clearly.
How the Procedure Works
There are two broad ways to create a cystostomy. The first is an open surgical approach, where a surgeon makes a small incision in the lower abdomen and cuts directly into the bladder wall to place a drainage tube. This method is typically used during other abdominal or pelvic surgeries when direct access is already available, or in emergencies where the bladder cannot be adequately visualized any other way.
The second and more common method today is percutaneous placement, meaning the catheter is inserted through the skin using a needle and guide wire, often with ultrasound or other imaging to confirm the bladder’s position. This can be done at the bedside or in a procedure room and takes only minutes. One study evaluating a dedicated percutaneous device found that procedures averaged under ten minutes from start to finish, with no complications and minimal blood loss across all cases.1PubMed Central. The transurethral suprapubic endo-cystostomy (T-SPeC): a novel suprapubic catheter insertion device Newer dedicated catheter kits have been developed specifically to make percutaneous insertion safer, and in a small evaluation of one such system, the vast majority of physicians reported feeling safer and more comfortable using the guided device compared to conventional cystostomy sets.2PubMed Central.

The key requirement for a safe percutaneous approach is that the bladder must be adequately full so it rises above the pubic bone and sits directly behind the abdominal wall, keeping loops of bowel out of the way. Patients who have had previous lower abdominal surgery, whose bladder cannot be adequately filled, or who have acute pelvic trauma that distorts normal anatomy are generally not candidates for this approach and may require open placement or an alternative strategy.3PubMed Central.

Emergency and Trauma Situations
One of the clearest reasons for a cystostomy is traumatic urethral injury. Pelvic fractures from car accidents, falls, or crush injuries can tear or completely sever the urethra, making it impossible to pass a catheter through the normal route. When that happens, a suprapubic catheter provides an immediate way to drain urine and relieve pressure on the bladder while the rest of the injuries are addressed.
In some of these cases, surgeons attempt to realign the torn urethra during the initial operation. But when the damage is too extensive, a cystostomy alone may be the only practical option. A case report of a young man with a severe pelvic fracture and a completely transected urethra documented that after suprapubic cystostomy alone, follow-up imaging showed the urethra had spontaneously reconnected within four months, allowing normal urination to resume.4PubMed Central. Spontaneous recanalization of complete urethral injury treated by suprapubic cystostomy alone after severe pelvic bone fracture in a young male patient in Korea: a case report That is an unusually good outcome, though, and should not be taken as the norm.
A systematic review comparing the two main strategies for pelvic-fracture urethral injuries found that attempting to realign the urethra right away led to a significantly lower stricture rate than cystostomy alone. However, the two approaches showed no meaningful difference in rates of erectile dysfunction or incontinence.5Urology. Primary Realignment vs Suprapubic Cystostomy for the Management of Pelvic Fracture–associated Urethral Injuries: A Systematic Review and Meta-analysis In an older but often-cited series of 64 patients managed initially with cystostomy and delayed reconstruction, about 95% eventually needed a secondary operation for impassable strictures, compared to roughly half of those who had primary realignment.6PubMed. Prostatomembranous urethral disruptions: management by suprapubic cystostomy and delayed urethroplasty So the cystostomy reliably handles the immediate crisis, but it does not eliminate the likelihood of further surgery down the road.
Long-Term Use for Neurogenic Bladder and Other Chronic Conditions
Not everyone who gets a suprapubic catheter has it for a short period after an injury. Some people need bladder drainage for months, years, or the rest of their lives. This includes people with spinal cord injuries, advanced multiple sclerosis, severe stroke, or other neurological conditions that prevent the bladder from emptying properly. It also includes some people with severe urethral strictures that cannot be repaired, or those with advanced prostate or pelvic cancers that obstruct the urinary tract.
Intermittent self-catheterization, where a person passes a small disposable catheter through the urethra several times a day, is generally considered the gold standard for neurogenic bladder management. But it requires good hand dexterity, motivation, and enough cognitive function to learn the technique. For people who cannot manage self-catheterization, a suprapubic catheter becomes a practical alternative. One review of suprapubic cystostomy in spinal cord injury patients noted that when modern management practices were followed, including anticholinergic medications, regular catheter changes, and bladder washouts, the complication profile was similar to that of intermittent catheterization.7PubMed. Contemporary role of suprapubic cystostomy in treatment of neuropathic bladder dysfunction in spinal cord injured patients An earlier long-term analysis came to a more tempered conclusion, noting that while continuous cystostomy drainage is not considered ideal, some patients with neurogenic bladder genuinely benefit from it when other options are not feasible.8PubMed.

Infection Rates Compared to Urethral Catheters
Catheter-associated urinary tract infections are one of the most common healthcare-associated infections, so the question of which catheter type causes fewer infections matters a great deal. The evidence here is more nuanced than many people expect.
A network meta-analysis comparing suprapubic tubes, standard urethral catheters, and intermittent catheterization in the post-surgical setting found that when catheters were needed for only a few days, there was no clear infection advantage to any of the three methods. But when drainage lasted longer than five days, both suprapubic tubes and intermittent catheterization were associated with significantly lower infection rates compared to urethral catheters.9PubMed. Comparison of Urinary Tract Infection Rates Associated with Transurethral Catheterization, Suprapubic Tube and Clean Intermittent Catheterization in the Postoperative Setting: A Network Meta-Analysis That five-day cutoff is a useful practical marker: for brief catheterization, the route probably does not matter much, but for anything longer, the suprapubic approach starts to pull ahead on infection risk.
An earlier randomized trial in general surgery patients was more emphatic. Of 34 patients catheterized through the urethra, nearly half developed urinary tract infections, compared to only two out of 32 suprapubic catheter patients.10British Journal of Surgery. Prospective randomized controlled trial of urethral versus suprapubic catheterization In long-term care, a study of nursing home residents found that after adjusting for other health differences, those with suprapubic catheters had a lower incidence of catheter-associated urinary tract infection than those with urethral catheters.11PubMed Central. Indwelling urethral versus suprapubic catheters in nursing home residents: determining the safest option for long-term use Large Cochrane reviews have similarly found that suprapubic catheterization tends to reduce bacteriuria, the need for recatheterization, and patient discomfort compared to the urethral route.12Scientific Scholar / American Journal of Interventional Radiology.

Complications and What Can Go Wrong
No catheter is risk-free, and the suprapubic route has its own set of potential problems. The most serious acute complication is bowel perforation. Because the catheter must pass through the abdominal wall, there is a small risk of puncturing a loop of intestine that has slipped between the bladder and the abdominal wall. A scoping review of this complication found that bowel perforations most commonly involve the small intestine, particularly the terminal ileum, and can lead to peritonitis and sepsis if not recognized and treated quickly.13PubMed Central. Intestinal Injury After Suprapubic Catheterisation: A Scoping Review A CT-based risk analysis confirmed that bowel interposition along the planned catheter path is the central danger of the procedure.14PubMed Central. Suprapubic cystostomy: risk analysis of possible bowel interposition through the percutaneous tract by computed tomography This is why adequate bladder filling and, ideally, ultrasound guidance are so important during placement.
Over time, other complications emerge. Bladder stones are a well-documented risk for anyone with an indwelling catheter, whether urethral or suprapubic. A large study of spinal cord injury patients found that those with suprapubic catheters had a roughly tenfold higher risk of bladder stone formation compared to patients using intermittent self-catheterization, with an absolute annual risk of about 4% per year. The risk of stones was essentially identical whether the catheter entered through the urethra or the abdominal wall. And once a patient formed one stone, the chance of forming another quadrupled.15PubMed. Bladder management and risk of bladder stone formation in spinal cord injured patients
Catheter encrustation is a related nuisance. Mineral deposits can build up on the catheter surface over time, sometimes making it difficult to deflate the balloon and remove the catheter during scheduled changes. When a catheter becomes truly stuck, options include specialized techniques to break up the encrustation.16PubMed Central. Encrusted and incarcerated urinary bladder catheter: what are the options? This is one reason why regular catheter changes are important. Current recommendations call for changing a suprapubic catheter every two to six weeks, depending on the catheter material and the individual patient’s tendency toward encrustation.17PubMed Central. Change of the suprapubic catheter: Not always safe! Even routine changes are not entirely without risk, and clinicians are advised to approach them with care, particularly in patients who have had the catheter for a long time or who have scar tissue around the tract.
Living with a Suprapubic Catheter
For people who need long-term catheterization, quality of life is at least as important as complication rates. The picture here is mixed, and a lot depends on what you compare it to.
A nationwide survey of long-term catheter users found that people using intermittent self-catheterization reported the best satisfaction and quality-of-life scores overall. Both indwelling urethral catheters and suprapubic catheters were independently associated with lower satisfaction.18PubMed Central. Patient satisfaction, quality of life, and catheter-related complications in long-term urinary catheter users: a nationwide survey But when suprapubic catheters are compared directly to urethral catheters, the suprapubic option often comes out ahead. After pelvic reconstructive surgery, women with suprapubic drainage reported meaningfully higher quality-of-life and satisfaction scores than women with urethral catheters, even though the suprapubic group had their catheters for longer.19PubMed. Suprapubic versus transurethral bladder drainage following reconstructive pelvic surgery: a comparison of patient satisfaction and quality of life
Qualitative interviews with long-term catheter users offer a more textured view. Some people who switched from a urethral to a suprapubic catheter described it as a clear improvement, citing fewer infections, better hygiene, more comfort, and an improved sense of control over their own care. The suprapubic route also tends to be preferred by people who are sexually active, since the catheter exits the lower abdomen rather than the genitals. That said, a suprapubic catheter does not eliminate body-image concerns or anxiety about intimacy. Some participants in one qualitative study reported that even with the catheter moved to the abdomen, they still worried about sex or avoided physical intimacy altogether.20Journal of Wound, Ostomy, and Continence Nursing. Comparing Transurethral and Suprapubic Catheterization for Long-term Bladder Drainage: A Qualitative Study of the Patients’ Perspective Patients also reported that having some say in the decision-making process, including where on the abdomen the catheter would be placed, contributed to their satisfaction.
When the Catheter Comes Out
If the underlying problem resolves, whether it is a urethral injury that heals, postsurgical swelling that subsides, or an obstruction that gets treated, the suprapubic catheter can be removed. In most cases, the tract through the abdominal wall closes on its own within a day or two once the catheter is pulled. The body treats the tract much like a wound, and the muscle and skin layers contract shut. Occasionally, a tract that has been open for a very long time may need minor surgical closure, but this is uncommon.
One practical complication during removal involves the catheter balloon. Silicone catheters in particular can develop a “cuffing” effect when the balloon is deflated, where the collapsed balloon material bunches up around the catheter tip and catches on the tract wall, making removal feel as if the catheter is stuck.21PubMed Central. Clinical skills: how to remove and change a suprapubic cathether Knowing that this is a mechanical issue rather than a sign of something more serious helps nurses and caregivers manage the situation without unnecessary alarm.
Research Into Better Catheter Materials
One area of active research aims to solve the chronic problems of encrustation and biofilm formation that plague all indwelling urinary catheters, including suprapubic ones. A European research initiative has explored a range of strategies to prevent mineral buildup on catheter surfaces. These include antibody coatings, enzyme treatments, biomimetic surfaces, bioactive nanocoatings, and even the use of bacteriophages, which are viruses that kill bacteria. Other approaches under investigation involve embedding pH sensors into catheter materials to detect early encrustation, developing biodegradable metals for catheter components, and using ultrasound energy to break up deposits before they become clinically problematic.22PubMed Central. Potential strategies to prevent encrustations on urinary stents and catheters – thinking outside the box: a European network of multidisciplinary research to improve urinary stents (ENIUS) initiative None of these technologies are in routine clinical use yet, but they represent a recognition that the catheter itself is a major contributor to complications and that better materials could meaningfully improve life for long-term users.
Cystostomy in Veterinary Medicine
Suprapubic cystostomy is not limited to human patients. In veterinary practice, tube cystostomy is a well-established treatment for obstructive urolithiasis, the condition where urinary stones block the urethra, particularly in small ruminants like goats and sheep. Male goats, especially castrated ones, are prone to urethral blockages because of their narrow, winding urethra. An early case series reported that tube cystostomy successfully relieved the obstruction in 12 out of 15 animals, with most able to urinate normally within about 11 to 12 days.23PubMed. Tube cystostomy for treatment of obstructive urolithiasis in small ruminants
A larger follow-up study confirmed these results, finding that roughly three-quarters of animals were successfully treated and that short- and long-term survival was good for those that made it through the initial hospitalization. Reobstruction occurred in fewer than one in five animals at six and twelve months. Pygmy goats and castrated males were overrepresented in the study, consistent with the known anatomy-related risk in these animals.24PubMed. Short- and long-term outcome and factors predicting survival after surgical tube cystostomy for treatment of obstructive urolithiasis in small ruminants The veterinary approach follows the same basic logic as the human one: bypass the blocked urethra, let urine drain safely, give the body time to heal, and then see if normal urination can resume once the tube is removed.
