Immediate Management: Decompression

Urinary Retention

For Acute Urinary Retention, the immediate goal is to relieve pain and prevent bladder rupture.

  • Urethral Catheterization: A Foley catheter is passed through the urethra into the bladder. This is the standard first-line treatment. Catheter size matters; typically, a 16Fr or 18Fr catheter is used.
  • Suprapubic Catheterization: If the urethra is blocked (e.g., by a stricture, an enlarged prostate, or a false passage from previous attempts) and a wire cannot pass, a catheter is inserted directly into the bladder through the skin of the lower abdomen using a needle and guide wire. This is performed under local anesthesia.
  • Slow vs. Rapid Decompression: Historically, it was taught to drain the bladder slowly (e.g., 500mL at a time) to prevent hypotension or hematuria. However, modern high-quality evidence suggests rapid, complete drainage is safe and effective, provided the patient is monitored for post-obstructive diuresis.

Medical Management (Pharmacotherapy)

Once the bladder is drained, medications are started to improve voiding mechanics, aiming for a “Trial Without Catheter” (TWOC).

  • Alpha-Blockers (Tamsulosin, Alfuzosin, Silodosin, Doxazosin): These drugs relax the smooth muscle of the prostate and bladder neck. They open the “internal door,” reducing outflow resistance. They are the mainstay of treatment for BPH-related retention. Tamsulosin is uroselective and has fewer cardiovascular side effects.
  • 5-Alpha Reductase Inhibitors (Finasteride, Dutasteride): These shrink the prostate gland volume by blocking the hormonal conversion of Testosterone to Dihydrotestosterone (DHT). They take 3-6 months to work, so they are for long-term prevention rather than acute crisis management.
  • Antibiotics: Used only if there is a documented infection. Asymptomatic bacteriuria in a catheterized patient is generally not treated to avoid the emergence of resistant “superbugs.”

Surgical Management: Relieving the Obstruction

If medication fails or the retention is recurrent, surgery is the definitive treatment to remove the blockage.

1. Transurethral Resection of the Prostate (TURP) The “Gold Standard” for decades. An electrified loop is used to shave away the inner core of the prostate tissue piece by piece, coring out the channel like an apple. It is highly effective but carries risks of bleeding, electrolyte imbalance (TUR syndrome), and retrograde ejaculation.

2. Holmium Laser Enucleation of the Prostate (HoLEP) A state-of-the-art technique performed at Liv Hospital. A high-power Holmium laser acts like a “tactical knife” to separate the entire prostate adenoma from its capsule. The tissue is pushed into the bladder and removed with a morcellator.

  • Advantage: Can treat massive prostates (>100g) that would otherwise require open surgery. It is anatomically complete (like peeling an orange), has less bleeding, and offers shorter catheter time (often <24 hours).

3. Minimally Invasive Therapies (MISTs)

  • Rezum (Water Vapor Therapy): Injecting sterile steam into the prostate to kill tissue, which the body reabsorbs over weeks.
  • Urolift: Using tiny implants to pin the prostate lobes back like curtains, mechanically opening the channel without cutting tissue.
  • Advantage: Preserves sexual function (ejaculation) better than TURP, but may not be suitable for gigantic glands or severe retention.

4. Prostatic Artery Embolization (PAE) An interventional radiology procedure where the blood supply to the prostate is blocked via the femoral artery, causing the gland to shrink. Suitable for patients who cannot undergo anesthesia.

5. Urethrotomy / Urethroplasty For Urethral Strictures. A laser or knife cuts the scar tissue (Urethrotomy), or the scarred segment is surgically removed and reconstructed using a graft from the mouth lining (Buccal Mucosa Graft Urethroplasty).

Management of Non-Obstructive (Acontractile) Retention

If the bladder muscle is dead (myogenic failure) or disconnected (neurogenic), opening the outlet won’t help. The pump is broken.

  • Clean Intermittent Catheterization (CIC): The patient learns to insert a single-use catheter 4-5 times a day to empty the bladder. This is the gold standard for safety and independence, mimics everyday bladder cycling, and reduces infection risk compared to permanent catheters.
  • Indwelling Catheter: A Foley or Suprapubic catheter left in place permanently. This is a last resort due to risks of infection, stones, and bladder cancer.
  • Sacral Neuromodulation (Interstim): A “bladder pacemaker” that stimulates the sacral nerves. It can sometimes restore voiding in patients with non-obstructive retention (like Fowler’s syndrome) by modulating the nerve signals.

Behavioral Management

  • Timed Voiding: Voiding on a schedule (every 3 hours) to prevent over-distension, even if the urge is not felt.
  • Double Voiding: Peeing, waiting 30 seconds, and trying again. This helps empty the residual urine by allowing the muscle to recover and contract a second time.

FREQUENTLY ASKED QUESTIONS

What is a "Trial Without Catheter" (TWOC)?

After you have a catheter placed for retention, we usually start you on medication (Alpha-blockers) for 3-7 days to relax the prostate. Then, you come to the clinic, we remove the catheter early in the morning, and observe you for several hours to see if you can pee on your own. We measure the residual urine. Suppose you can empty efficiently, great. If not, the catheter is replaced, and we discuss surgery options.

Insertion can be uncomfortable, but once it is in, it should not be painful. You may feel a sensation of “needing to pee” because the balloon is stimulating the bladder base, but this usually subsides. If you have sharp pain, the catheter may be blocked, in the wrong position, or causing bladder spasms.

If the cause is obstruction (like a large prostate), surgery (TURP/HoLEP) has a very high cure rate (>90%). If the cause is a weak bladder muscle (acontractile), surgery to open the prostate might help gravity drainage, but it won’t restore the muscle power. Urodynamics helps predict this success rate before surgery.

The most common side effects are dizziness (due to lower blood pressure, orthostatic hypotension), stuffy nose, and “Retrograde Ejaculation” (where semen goes backward into the bladder during climax, resulting in a dry orgasm). This is not dangerous but can be bothersome for some men.

It sounds daunting, but it is a simple, clean technique that thousands of people do daily. Liv Hospital nurses provide hands-on training. It takes about 2 minutes to do, gives you complete freedom (no bag attached to your leg), and protects your kidneys better than any other method.
