Most people notice blood in their urine for several weeks after aquablation, though the heaviest bleeding typically resolves within the first few days. The amount and duration vary depending on prostate size, how the procedure was performed, and your activity level during recovery. Light pink or tea-colored urine can persist on and off for up to four to six weeks as the internal surgical site heals.
What Causes the Bleeding
Aquablation uses a high-pressure waterjet to remove excess prostate tissue that blocks urine flow. Unlike traditional procedures that cut and cauterize simultaneously, the waterjet removes tissue first, and then your surgeon controls bleeding separately, either with a heated loop or by inflating a catheter balloon against the treated area for up to two hours to apply pressure. This two-step approach means the raw tissue surface inside your prostate needs time to heal on its own after surgery.
A catheter with continuous bladder irrigation is placed immediately after the procedure to flush out blood and prevent clots from forming. This catheter typically stays in place for one to three days. While the catheter is in, your urine bag will likely appear red or dark pink, which is normal.
The Typical Bleeding Timeline
The first 48 hours tend to involve the most visible bleeding, which is why you’ll still have a catheter and bladder irrigation during this window. Once the catheter comes out, you may notice your urine looks clear or only slightly pink for a day or two, then becomes bloody again. This pattern of intermittent bleeding is common and happens because internal scabs form and then shed as the tissue heals, similar to how a scraped knee might reopen.
Most people see occasional blood in their urine for two to four weeks, sometimes longer. Drinking extra water helps dilute the blood and flush small clots before they cause problems. If you notice a sudden increase in bleeding after a period of clear urine, it usually means a scab has come loose. Increasing your fluid intake and resting for the remainder of the day is typically enough to manage these episodes.
Activities That Can Restart Bleeding
For the first 48 hours, avoid brisk exercise and heavy lifting entirely. After that, you can gradually return to normal activities as you feel able, but pushing too hard too soon is the most common trigger for a bleeding flare. Straining during bowel movements, vigorous exercise, prolonged sitting, and sexual activity can all irritate the healing tissue and cause fresh bleeding weeks into recovery.
Many urologists recommend avoiding strenuous activity for two to four weeks, even though you may feel physically fine much sooner. The internal wound takes longer to heal than you’d guess from how you feel on the outside.
How Often Serious Bleeding Occurs
Significant bleeding that requires medical intervention is uncommon. Early data from aquablation procedures showed a hemorrhage rate of about 8.3%, but as surgical techniques have improved, particularly with more systematic use of cautery during the procedure, that rate has dropped to around 1.4%. Larger prostates carry a higher risk of post-operative bleeding simply because more tissue is removed, leaving a larger raw surface to heal.
Signs That Need Immediate Attention
Some bleeding is expected, but certain symptoms signal a problem. Contact your surgeon’s office if you:
- See blood clots in your urine, especially if they make it difficult to urinate
- Cannot empty your bladder at all
- Have a fever of 101°F or higher
- Feel dizzy or weak
- Experience pain or burning that keeps getting worse rather than improving
Clots are the main concern because they can block urine flow entirely, which creates a painful and urgent situation. If your urine stream weakens and your urine turns dark red with visible clots, don’t wait to see if it resolves on its own.
Blood Thinners and Bleeding Duration
If you take blood thinners or antiplatelet medications, your bleeding may last longer and be heavier than average. Your surgeon will give you specific instructions about when to stop these medications before the procedure and when to restart them afterward. The timing varies depending on which medication you take and your cardiovascular risk, so this is one of the most important conversations to have with both your urologist and the doctor who prescribes your blood thinner. Restarting too early increases bleeding risk; waiting too long increases clotting risk.
Helping Your Body Heal Faster
Staying well-hydrated is the single most useful thing you can do during recovery. Aim for enough water that your urine stays light in color (aside from the blood). This keeps small clots from forming in your bladder and helps the tissue heal cleanly. Avoid caffeine and alcohol in the first week or two, as both can irritate the bladder and increase bleeding. Stool softeners help prevent straining, which is a surprisingly common cause of delayed bleeding episodes after prostate procedures.
