If you can't urinate after surgery (Postoperative Urinary Retention or POUR), contact your healthcare provider immediately, as the bladder needs to be drained to prevent damage; they will likely insert a temporary catheter to empty it, and treatment often involves this short-term drainage, sometimes with medications like alpha-blockers, until bladder function returns, which is a common issue that usually resolves with time.
[12] One should also take note of how long it has been since a postoperative patient's last void. Most patients should go no more than 6 to 7 hours without passing some urine.
If you did not go home with a catheter, drink fluids and spread them throughout the day. Also, avoid drinking a lot at bedtime. If you did go home with a catheter, drink fluids regularly throughout the day. Avoid alcohol and caffeine.
Surgery. You may experience urinary retention after having joint replacement surgery (such as hip replacement) or spinal surgery. Having general anesthesia during a procedure can also cause temporary urinary retention.
Leaning forward and rocking may promote urination. After you have finished passing urine, squeeze the pelvic floor muscle and then relax it, to try and completely empty. Tapping over the bladder may assist in triggering a contraction in some people.
For mild cases, you can try these home remedies:
A: Most adults can safely hold their pee for about 3 to 5 hours, but it's best not to wait that long. Holding it too often can irritate your bladder and increase your risk of infection. The average bladder holds 400–600 mL of urine. “Go” when you first feel the urge, especially on long trips.
With acute urinary retention, a health care professional will immediately drain the urine from your bladder using a catheter. Removing the urine from the bladder eases your pain and helps prevent your bladder and kidneys from being damaged.
To facilitate the process of urination after catheter removal, consider the following helpful suggestions:
Use your fingers to tap firmly over your bladder (just above your pubic bone). This can help the bladder muscle to contract and allow more urine to flow. Learn to relax your pelvic floor muscles. This will also help you to empty your bladder more completely.
The "21-second pee rule" comes from a scientific discovery that most mammals over about 3 kg (like dogs, cows, elephants) empty their bladders in roughly 21 seconds, regardless of their size, due to physics involving urethra length and gravity. For humans, this serves as a loose benchmark: urinating significantly faster (e.g., under 10 seconds) or slower (over 30 seconds) might signal holding it too long or an overactive bladder, though it's not an exact diagnosis.

Effects of Anesthesia and Pain Medications
Anesthesia can slow down the normal movement of your intestines, leading to sluggish bowel activity. Pain medications, particularly opioids (like oxycodone), are another common cause of constipation after surgery.
Catheterization. However, if you can't pee after surgery, a urinary catheter is the best treatment for a full bladder that does not respond to repeated attempts to urinate. 3 Your healthcare provider may recommend a catheter, even if you didn't need one during your procedure.
See a health care professional right away if you are unable to urinate or have severe pain in your abdomen. Acute urinary retention can be life threatening.
Diuretic medicine increases the production and flow of urine from your body. By removing excess fluid from your body in the afternoon, it may improve symptoms at night.
See your doctor immediately if your bladder feels full but you cannot urinate at all. If your doctor is not available, go to the emergency department. Acute urinary retention needs treatment straight away.
Bladder catheterization is the standard treatment of POUR, however, further studies are necessary to establish patients who need a bladder catheter, bladder volume thresholds and duration of catheterization.
For 2 days after your catheter is removed, your bladder and urethra will be weak. Do not push or put effort into urinating. Let your urine pass on its own. Do not strain to have a bowel movement (poop).
If you haven't urinated for 6 hours, you may have urinary retention. This is fairly common after some surgeries. But it could become serious if left untreated. Treatment includes draining the bladder with a small tube called a catheter.
You should seek emergency care if you can't urinate and have pain in your lower abdomen. If you are experiencing chronic urinary retention, you may have a weak or slow urine stream or urinate in frequent, small amounts.
A healthy bladder can hold up to 500 ml of urine before it's full. It takes your body almost 9 to 10 hours to produce 500 ml of urine. That's about how long you can hold your urine and still be in the safe zone without damaging your organs.
The body takes about 9 to 10 hours to produce 400-500 ml of urine. This is the safe time frame where holding urine will not harm your organs. Your bladder is an organ that can stretch. The process of emptying the bladder involves coordination between the bladder muscles and the abdominal muscles.
See a healthcare provider as soon as possible if you have decreased urine output. Anuria treatment depends on the cause. If the cause is heart failure, sepsis, shock or another emergency medical condition, the first priority for a provider is to treat that condition.
