Perform comprehensive preoperative assessment, including prostate-specific antigen (PSA) levels, urinalysis, urine culture, and coagulation profile. Ensure patient is NPO for at least 8 hours. Administer prophylactic intravenous antibiotics and obtain informed consent. Discontinue anticoagulants as per medical guidelines.
Monitor vital signs and post-operative bleeding. Maintain continuous bladder irrigation (CBI) to prevent clot formation until urine clears. Manage pain and encourage early ambulation. Monitor hemoglobin/hematocrit for potential hemorrhage. Remove catheter upon clinical clearance and ensure patient can void spontaneously before discharge.
Comprehensive Clinical Guide: Transurethral Resection of the Prostate (TURP)
Transurethral Resection of the Prostate (TURP) remains the "gold standard" surgical intervention for the treatment of Benign Prostatic Hyperplasia (BPH). Despite the emergence of various minimally invasive surgical therapies (MIST), TURP continues to demonstrate superior long-term outcomes in alleviating lower urinary tract symptoms (LUTS) secondary to bladder outlet obstruction (BOO). This guide provides an exhaustive clinical overview of the procedure, from patient selection to long-term post-operative management.
1. Introduction and Overview
BPH is a progressive condition characterized by the non-malignant enlargement of the prostate gland, which often results in the compression of the prostatic urethra. TURP is a minimally invasive endoscopic procedure performed via the urethra, involving the systematic excision of prostatic adenomatous tissue. By removing the obstructive tissue, surgeons restore the patency of the urinary channel, significantly improving voiding efficiency and quality of life for patients.
Core Objectives of TURP
- Decompression: Relieving the physical obstruction at the bladder neck and prostatic urethra.
- Symptom Resolution: Alleviating storage and voiding symptoms (urgency, frequency, nocturia, weak stream).
- Complication Prevention: Reducing the risk of urinary retention, recurrent UTIs, bladder stones, and renal insufficiency.
2. Technical Specifications and Mechanisms
The procedure is executed using a resectoscope, an instrument equipped with a light source, a camera, and a wire loop electrode. The mechanism relies on electrocautery (monopolar or bipolar) to simultaneously excise tissue and achieve hemostasis.
The Bipolar Advantage
Modern urological practice has largely shifted toward Bipolar TURP (B-TURP). Unlike traditional monopolar TURP, which uses non-conductive irrigation (glycine), bipolar systems utilize conductive saline.
| Feature | Monopolar TURP | Bipolar TURP |
|---|---|---|
| Irrigation Fluid | Glycine (non-conductive) | Saline (0.9% NaCl) |
| Current Path | From electrode through patient to grounding pad | Within the loop (localized circuit) |
| TUR Syndrome Risk | Higher (due to fluid absorption) | Negligible |
| Hemostasis | Good | Superior |
3. Clinical Indications and Usage
The decision to proceed with TURP is based on the failure of conservative management (watchful waiting) and pharmacotherapy (alpha-blockers, 5-alpha-reductase inhibitors).
Absolute Indications
- Refractory Urinary Retention: Failure of a trial without a catheter (TWOC).
- Recurrent Urinary Tract Infections: Caused by residual urine/stasis.
- Bladder Calculi: Secondary to chronic obstruction.
- Gross Hematuria: Recurrent episodes of prostatic origin.
- Renal Impairment: Obstructive uropathy leading to hydronephrosis or elevated creatinine.
Relative Indications
- Severe LUTS (IPSS score > 20) that significantly impairs quality of life.
- Patient preference for definitive surgical management over lifelong medication.
4. Pre-Operative Preparation
Preparation is critical to minimizing surgical morbidity.
- Urodynamic Assessment: To confirm bladder outlet obstruction and rule out detrusor underactivity.
- Imaging: Transrectal ultrasound (TRUS) or MRI to estimate prostate volume (essential for planning resectability).
- Laboratory Workup:
- PSA Testing: To rule out occult prostate cancer.
- Urinalysis/Culture: Must be sterile before surgery; antibiotics are administered if infection is present.
- Coagulation Profile: Patients on antiplatelets/anticoagulants must undergo a structured washout period as per cardiology guidelines.
- Patient Counseling: Discussion regarding retrograde ejaculation (the most common side effect) and the potential for temporary urinary incontinence.
5. The Procedure: A Step-by-Step Breakdown
- Anesthesia: Usually performed under spinal or general anesthesia.
- Cystoscopy: Systematic inspection of the urethra, bladder, and prostate anatomy.
- Resection: The surgeon utilizes the wire loop to excise the prostate tissue in "chips." The resection typically begins at the bladder neck and proceeds toward the verumontanum.
- Hemostasis: Continuous coagulation of bleeders using the electrode to ensure a clear field.
- Evacuation: The resected chips are evacuated from the bladder using an Ellik evacuator.
- Catheterization: A large-bore (22-24Fr) three-way Foley catheter is inserted for Continuous Bladder Irrigation (CBI).
6. Post-Operative Recovery and Protocol
The immediate post-operative period focuses on preventing clot retention and ensuring bladder drainage.
- CBI Management: Irrigation rates are adjusted based on the color of the urine (aiming for "rosé" or clear).
- Catheter Removal: Typically performed 24–48 hours post-op, provided the urine is clear of significant hematuria.
- Activity Restrictions: No heavy lifting (>10 lbs) or strenuous exercise for 4–6 weeks to prevent secondary hemorrhage.
- Pharmacology: Analgesics for bladder spasms and stool softeners to prevent straining during bowel movements.
7. Risks, Complications, and Contraindications
While highly successful, TURP is an invasive surgical procedure with inherent risks.
Potential Complications
- Retrograde Ejaculation: Occurs in 65–80% of patients; the bladder neck is opened, allowing semen to enter the bladder rather than exiting the urethra.
- Urinary Incontinence: Rare (1–2%), usually temporary.
- Urethral Stricture/Bladder Neck Contracture: Long-term scarring from the procedure.
- TUR Syndrome: A rare but dangerous hyponatremia caused by excessive absorption of irrigation fluid (mostly associated with monopolar TURP).
- Hemorrhage: Risk of secondary bleeding 1–3 weeks post-op due to sloughing of the eschar.
8. Alternative Treatments
Patients seeking alternatives to TURP may consider:
* HoLEP (Holmium Laser Enucleation of the Prostate): Superior for very large prostates (>80-100g).
* PVP (Photoselective Vaporization): Using GreenLight laser to vaporize tissue; excellent for patients on anticoagulants.
* UroLift/Rezum: Minimally invasive office-based procedures for milder cases.
9. Frequently Asked Questions (FAQ)
1. Is TURP a cure for prostate cancer?
No. TURP is specifically for Benign Prostatic Hyperplasia. It does not treat or prevent prostate cancer.
2. Will I be impotent after TURP?
Erectile dysfunction is not a direct result of the surgery itself, though it is a known risk of any pelvic surgery due to potential nerve injury. The risk is significantly lower with TURP compared to radical prostatectomy.
3. How long do the results of a TURP last?
TURP is a durable procedure. Most patients experience long-term relief, though the prostate can technically grow back over 10–15 years, potentially requiring a repeat procedure.
4. When can I return to work?
Sedentary work can be resumed in 1–2 weeks; physical labor should be avoided for at least 4–6 weeks.
5. Why do I have to use a catheter after surgery?
The catheter serves two purposes: keeping the bladder empty to allow the raw prostatic bed to heal and providing a channel for continuous irrigation to prevent blood clots.
6. Is TURP painful?
Post-operatively, patients may experience bladder spasms, which can feel like a sudden, sharp need to urinate. This is managed with medications like oxybutynin.
7. Can I have sex after the procedure?
Patients are generally advised to abstain from sexual activity for 4–6 weeks to allow the prostatic fossa to re-epithelialize.
8. Will my urine look different?
Initially, it will be blood-tinged. Over a few weeks, it should return to a normal yellow color.
9. What is the success rate?
TURP has a success rate of approximately 90–95% in terms of symptom improvement.
10. What if my PSA is still high after TURP?
PSA levels will drop after TURP because the bulk of the prostate tissue is removed. If PSA remains elevated or rises, a biopsy is mandatory to rule out malignancy.
10. Conclusion
Transurethral Resection of the Prostate remains the benchmark for surgical BPH management. Through a deep understanding of the physiological obstruction and the application of standardized surgical techniques, urologists can provide life-changing relief for men suffering from urinary symptoms. While newer technologies are emerging, the reliability, cost-effectiveness, and proven long-term data associated with TURP ensure its continued dominance in clinical urology.
