Recruiting studies
- NCT07379814Recruiting
New muscle surgery for urinary retention
This trial tests a surgery that uses a muscle from your belly to help your bladder empty. It may be an option if you have trouble urinating because your bladder muscle is too weak to contract.
Cleveland, OhioAges 18–75 - NCT07603011Recruiting
Catheter timing after prostate laser surgery for urinary problems
This study looks at how long patients should keep a urinary catheter (a tube that drains urine) after having laser surgery to remove prostate tissue. Researchers want to understand what timing works best for patients who couldn't urinate before surgery.

Early vs. delayed catheter removal in men with sudden urinary retention
This study compares two approaches for men who have had a catheter placed for sudden urinary blockage: trying to remove the catheter early (after 1 day) versus waiting a few more days. It aims to see which timing works better to help you urinate without the catheter.
Harderwijk, GelderlandAges 18 years+ - NCT07650968RecruitingPhase 4
Prostate Medication Adjustment After Sudden Inability to Urinate
This trial tests whether increasing your prostate medication (tamsulosin) or switching to a different medication (silodosin) helps you urinate normally again after a sudden blockage caused by an enlarged prostate. The goal is to help you avoid long-term catheter use.
Banī Suwayf, Beni Suweif GovernorateAges 50 years+ - NCT04707001Recruiting
Tests urine problems after knee replacement surgery
This study looks at urinary retention (when you can’t pee normally) after elective total knee replacement. It may help doctors understand who is at risk and how to reduce this problem after surgery.
JyväskyläAges 18 years+ - NCT07174349RecruitingPhase 4
Medication to prevent urine retention after spine surgery
This trial tests whether a medication called tamsulosin can prevent or shorten the time you need a urinary catheter after spine surgery. It is for people having specific types of neck or lower back surgery.
Rochester, MinnesotaAges 35 years+ - NCT06978205Recruiting
Balloon dilation for urine retention after spinal cord injury

Jinan, ShandongAges 18–80 - NCT04597372RecruitingPhase 2
Tamsulosin for bladder urine retention after pelvic surgery
This trial studies whether tamsulosin can help drain the bladder when urine builds up after pelvic reconstructive surgery. It may help reduce the time and problems caused by “post-operative urinary retention.”
Pittsburgh, PennsylvaniaAges 18 years+ - NCT03609580RecruitingPhase 1/Phase 2
Testing Flomax to prevent urine retention after chest surgery
This study looks at whether starting Flomax around the time of thoracic (chest) surgery can help prevent a painful problem called urinary retention (not being able to pee after surgery). You might benefit if you’re at risk of not urinating after your operation and can safely take Flomax.
Hackensack, New JerseyAges 50 years+ - NCT06262048RecruitingPhase 2
Preventing urinary retention after chest surgery
This trial tests whether a medication called tamsulosin (commonly used for prostate problems) can help prevent trouble urinating after chest surgery. You may be eligible if you are at higher risk for this complication and have some urinary symptoms.
London, OntarioAges 40 years+ - NCT05657990RecruitingEarly Phase 1
Preventing trouble peeing after chest cancer surgery
This early-phase trial tests whether taking tamsulosin-like treatment around the time of chest cancer surgery can prevent urinary retention, when people cannot pee after surgery. It may help lower the chance of needing extra catheter care after the operation.
Brick, New JerseyAges 55 years+ - NCT06442995RecruitingPhase 4
Magnesium added to morphine after C-section to prevent urine blockage
This study tests whether adding magnesium sulfate to the usual painkiller (morphine) given through the epidural can help prevent trouble urinating after a C-section. It is for women who have had a C-section under epidural anesthesia and are at risk of needing a catheter due to urine retention.
ReimsAges 18 years+ - NCT07654413RecruitingPhase 4
Tamsulosin with or without tadalafil for catheter removal after urinary retention
This trial tests whether adding tadalafil to tamsulosin helps men pass a catheter removal test after a first-time urinary blockage caused by an enlarged prostate. The goal is to find which treatment works best to avoid needing a catheter again.
Banī Suwayf, Beni Suweif GovernorateAges 50 years+ - NCT07235371Recruiting
Electrical Acupoint Stimulation for Bladder Recovery After Cervical Cancer Surgery
This study tests whether a gentle, non-invasive electrical stimulation on specific acupoints (like acupuncture points) can help you regain bladder control after cervical cancer surgery. If you've had a catheter for a few weeks and haven't been able to pee on your own, this might be an option to help retrain your bladder.
Hangzhou, ZhejiangAges 18–70 - NCT07050277RecruitingPhase 3
Morphine for bladder issues after knee replacement
This study tests whether adding morphine to spinal anesthesia can reduce trouble urinating after a second knee replacement surgery. It may help you avoid needing a catheter after surgery.
Toronto, OntarioAges 21 years+ - NCT06179654Recruiting
Pelvic floor therapy before prostate surgery for leaking
This trial tests if doing pelvic floor physical therapy before prostate surgery (HoLEP) helps reduce stress urinary incontinence (leaking after sneezing, coughing, or laughing). It may help patients who are scheduled for this surgery due to an enlarged prostate.
Cleveland, OhioAges 18 years+ - NCT06037356Recruiting
Comparing two surgeries for enlarged prostate with urinary retention
This trial compares two surgeries for men with an enlarged prostate who have trouble urinating and need a catheter. It helps find out which procedure works better for getting patients back to normal urination.
Hong KongAges 40 years+ - NCT06918067Recruiting
Comparing catheter types for urine flow
This study compares different types of catheters to see how well they help empty the bladder. If you are a woman who uses catheters regularly, you might be able to join and help improve catheter design.
Charlotte, North CarolinaAges 18 years+ - NCT06769087Enrolling by invitation
Removing urinary catheter right after colorectal cancer surgery
This study compares taking out the urinary catheter immediately after colorectal cancer surgery versus leaving it in for one day. It aims to see which approach leads to fewer complications and faster recovery.
Seoul, SeoulAges 19–80 - NCT07714694Recruiting
Testing a new intermittent catheter for men
This study asks men who use a specific type of catheter (hydrophilic, size 14 French, 40 cm long) at least three times a day to try a new catheter and share their experience through online questionnaires. The goal is to see how well the new catheter works for daily use.
Libertyville, IllinoisAges 22 years+ - NCT05439902Recruiting
Tamsulosin for painful urination in women with multiple sclerosis
This trial studies whether tamsulosin can improve painful or difficult urination (dysuria) in women who have multiple sclerosis. It focuses on people whose symptoms are linked to bladder coordination problems, with stable ongoing treatment.

Does Shower Standing Help Women Empty Bladder After Catheter Removal?

AshdodAges 18–99 - NCT06843538RecruitingPhase 3
Tamsulosin for Easier Urination After Pelvic Floor Surgery
This trial tests whether the drug tamsulosin (a medication that relaxes bladder muscles) helps you urinate more easily right after same-day surgery for pelvic organ prolapse or incontinence. It aims to reduce the need for a catheter after surgery.

- How do I know if I qualify for a urinary retention trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a urinary retention trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
