One of a Urologic emergency condition that we are going to discuss today is an acute urinary retention. The condition is most prevalent and common in male patient rather than the female. So the topic wills mainly focusing on the acute urinary retention in male patients. Typically, it happens in older gentleman who over 60 years and they were the most often group that realized and faced the condition of symptom. The following risks factors below shall have considered while the patients suffering from it;

Facteurs de risque de rétention urinaire
- Hypertrophie bénigne de la prostate (HBP) - Le facteur de risque le plus courant chez l'homme âgé ne peut être évité ou ignoré. Il s'agit de l'hypertrophie de la prostate. En règle générale, elle se traduit par l'apparition progressive d'un flux urinaire insuffisant chez les hommes de plus de 50 ans. Le traitement approprié par un urologue est capable de minimiser le risque de rétention urinaire dans l'avenir.
- Urethral stricture – Having history of urethral infection, STDs or Endoscopic urological procedure might induce a urethral scarring process which will makes urethral lumen narrowing and finally obstructed.

- Urethral stone – A rare condition which is occurred by urinary tract stone occluded inside the urethral lumen and that would need an emergency evacuation.

- Infections - Infection de la vessie, infection de la prostate ou infection urétrale peuvent provoquer une irritation sévère dans ces zones et, par conséquent, la rétention urinaire aiguë peut persister.

- Medications – Certain medications can interfere with bladder function. When the causative drug is stopped, acute urinary retention typically resolves.

- Constipation – Stool compacted in the rectum can compress the urethra and obstruct urinary flow, making constipation a surprisingly common and easily correctable cause of urinary retention.

- Limited ambulation – The bladder is controlled by the brain, which typically allows voiding in a quiet, standing position. Patients confined to bed often struggle to urinate and can improve simply by being encouraged to walk and stand.

- Neurological causes – A complicated condition that should be needed more carefully assessment by Urologist.
- Bladder dysfunction – Another rare bladder condition which cannot contract well and end up with full bladder.
An urgent management which we had always performed is the bladder decompression with urethral catheter or suprapubic tube insertion to release a large amount of the urines from the bladder before it becomes rupture. Then the certain treatment will be depended and done by a well-trained Urologist. Patient must be educated about plan of the treatment and the possibility causes of the retention. A few complications after draining a large volume of urine, such as hematuria, should be explained to the patient in advance to prevent unnecessary alarm.

Frequently Asked Questions about Acute Urinary Retention in Men
Acute urinary retention is a urological emergency in which a person is suddenly unable to urinate despite having a full bladder. It is most common in men over the age of 60 and causes significant pain and discomfort. Immediate treatment with bladder catheterization is required to relieve the obstruction and prevent bladder injury.
Benign Prostatic Hyperplasia (BPH), or enlargement of the prostate gland, is the most common cause of acute urinary retention in men. As the prostate grows, it gradually compresses the urethra, reducing urinary flow and increasing the risk of complete obstruction. Other causes include urethral stricture, infection, medications, constipation, and neurological conditions.
Yes. Several drug classes can impair bladder contractility or increase urethral resistance, leading to urinary retention. Common culprits include antihistamines, decongestants, anticholinergics, antidepressants, and opioid pain medications. In many cases, stopping the offending medication resolves the retention without further intervention.
The immediate treatment is bladder decompression via urethral catheterization or, in some cases, suprapubic tube insertion. This relieves the obstruction and prevents bladder rupture. After decompression, a urologist will investigate the underlying cause and plan definitive treatment, which may include medications, minimally invasive procedures, or surgery depending on the diagnosis.
Yes, mild hematuria (blood in urine) after draining a large volume of retained urine is a known and usually self-limiting complication. It occurs due to sudden decompression of the bladder wall and the release of small mucosal blood vessels. It typically resolves within 24–48 hours with adequate hydration. Your urologist will monitor this and advise if further evaluation is needed.
