Tamsulosin With or Without Tadalafil for Trial Without Catheter After Acute Urinary Retention Due to Benign Prostatic Hyperplasia (TAMS-TAD-TWOC)
Tamsulosin With Versus Without Tadalafil for Trial Without Catheter After Acute Urinary Retention Due to Benign Prostatic Hyperplasia: A Prospective Double-Blind Randomized Trial
Acute urinary retention is a common emergency in men with benign prostatic hyperplasia. After bladder drainage with a urethral catheter, patients usually undergo a trial without catheter to determine whether they can pass urine again without recatheterization.
This study will evaluate whether adding tadalafil 5 mg once daily to tamsulosin 0.4 mg once daily improves the chance of successful trial without catheter in men with first-episode acute urinary retention due to presumed benign prostatic hyperplasia.
Participants will be randomly assigned to receive either tamsulosin plus tadalafil or tamsulosin plus a matching placebo. Study medication will start within 24 hours after catheterization. The catheter will be removed on Day 7. If the first trial without catheter fails, the catheter will be reinserted and a second rescue trial without catheter will be performed on Day 14.
The main outcome is overall catheter-free success by Day 14. Participants will also be followed for recurrent urinary retention, post-void residual urine, urinary flow, catheter-related complications, drug-related adverse events, and the need for benign prostatic hyperplasia-related surgery within 3 months.

Comparador de Placebo: Tamsulosin Plus Placebo
Participants will receive tamsulosin 0.4 mg once daily plus a matching placebo once daily.
Treatment will start within 24 hours after urethral catheterization and continue until the Day-7 trial without catheter.
Participants who fail the Day-7 trial without catheter will continue the assigned treatment until the rescue trial without catheter on Day 14.
|
Tamsulosin 0.4 mg will be administered orally once daily as open-label background therapy in both study arms.
Treatment will start within 24 hours after urethral catheterization and continue until the scheduled Day-7 trial without catheter.
Participants who fail the Day-7 trial without catheter will continue treatment until the rescue trial without catheter on Day 14.
A matching placebo tablet will be administered orally once daily in the placebo comparator arm in addition to open-label tamsulosin 0.4 mg once daily.
The placebo will be identical to tadalafil in appearance, packaging, and labeling to maintain blinding.

Experimental: Tamsulosin Plus Tadalafil
Participants will receive tamsulosin 0.4 mg once daily plus tadalafil 5 mg once daily.
Treatment will start within 24 hours after urethral catheterization and continue until the Day-7 trial without catheter.
Participants who fail the Day-7 trial without catheter will continue the assigned treatment until the rescue trial without catheter on Day 14.

Treatment will start within 24 hours after urethral catheterization and continue until the scheduled Day-7 trial without catheter.
Participants who fail the Day-7 trial without catheter will continue treatment until the rescue trial without catheter on Day 14.

Overall Catheter-Free Success by Day 14
Prazo: Day 14
|
Proportion of participants who achieve successful spontaneous voiding after either the scheduled Day-7 trial without catheter or the rescue Day-14 trial without catheter.
Success is defined as spontaneous voiding after catheter removal, voided volume of at least 100 mL, post-void residual urine less than 150 mL measured within 10-15 minutes after voiding, no recatheterization within 24 hours after the relevant trial without catheter attempt, and remaining catheter-free until Day 14 for participants who initially pass the Day-7 trial without catheter.
