Benign prostatic hyperplasia (BPH) affects more than half of men by age 60 and almost 90 percent by age 85, often causing weak urinary stream, frequent nighttime urination, and incomplete bladder emptying. TURP surgery — short for transurethral resection of the prostate — has been the standard surgical treatment for BPH for decades. The procedure removes obstructing prostate tissue from inside the urethra, with no external incisions. Modern variations using bipolar energy and laser systems have made the surgery safer and more accessible than the original monopolar TURP introduced in the mid-20th century.
What TURP Is and Who Needs It
BPH is non-cancerous enlargement of the prostate that compresses the urethra and obstructs urine flow. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), treatment indications for surgery include severe symptoms not controlled by medication, urinary retention requiring catheterization, recurrent urinary tract infections, bladder stones, kidney damage from back-pressure, and persistent blood in the urine from prostate tissue.
TURP is typically considered for prostates between 30 and 80 grams. Larger glands often do better with simple prostatectomy or laser enucleation (HoLEP). Smaller glands may respond to less invasive office procedures.
How the Procedure Is Performed
TURP uses no external incisions. Under spinal or general anesthesia, the surgeon passes a resectoscope — a slim instrument combining a camera, irrigation channel, and electrical loop — through the urethra into the prostate. Tissue is shaved away in small chips that are flushed out at the end of the procedure. The American Urological Association describes the modern bipolar version, which uses saline irrigation rather than the older glycine solution and significantly reduces the risk of “TURP syndrome” (fluid absorption causing electrolyte imbalance).
Total operating time is usually 60 to 90 minutes. After surgery, a three-way catheter with continuous bladder irrigation runs for 24 to 48 hours to clear blood and small clots. Hospital stays typically run 1 to 2 nights, though some centers now perform same-day discharge in selected patients.
Laser variations of TURP, including HoLEP (holmium laser enucleation), GreenLight PVP (photoselective vaporization), and ThuLEP (thulium laser), achieve similar results with less bleeding and shorter catheter times in many cases.
Preparation and What to Expect on the Day
Pre-operative work-up usually includes a urinalysis and urine culture (active infection must be treated first), basic labs, an electrocardiogram, and sometimes urodynamic testing. PSA testing and prostate exam are routine to ensure cancer is not present. Blood thinners are stopped on schedule.
You will fast after midnight and arrive several hours before surgery. After the procedure, you wake up with the irrigation catheter in place. Pain is usually mild because there are no external incisions, though bladder spasms can be uncomfortable and are treated with anticholinergic medications. Most patients walk the same day.
Recovery Timeline
The catheter is usually removed at 1 to 3 days, after which you spend a few hours in the hospital to confirm you can urinate. Cleveland Clinic notes that most men return to desk work within 2 weeks and to full activity, including exercise and sex, within 4 to 6 weeks.
Expect blood-tinged urine off and on for 2 to 6 weeks as the prostate heals. Increased urinary frequency and urgency are common during the first month. Most surgeons advise drinking plenty of water, avoiding heavy lifting for 4 weeks, and not driving while on opioid medication. Constipation should be avoided to prevent straining and bleeding.
When to seek emergency care: Call 911 or go to the nearest emergency room if you experience inability to urinate, heavy bleeding with clots, fever above 101 degrees Fahrenheit, severe pelvic pain, calf pain or swelling, or signs of severe urinary tract infection such as flank pain with chills.
Risks, Complications, and Outcomes
TURP is one of the most studied surgical procedures in urology, with decades of outcome data. Most men experience significant improvement in urinary symptoms — peak flow rates roughly double on average, and quality-of-life scores improve substantially.
Common side effects include retrograde ejaculation (semen flows backward into the bladder during orgasm) in 50 to 75 percent of men. The orgasm sensation is preserved, but ejaculate volume drops dramatically. This is permanent and is the main reason younger or fertility-conscious patients sometimes prefer prostatic urethral lift (UroLift) or water vapor therapy (Rezum), which preserve antegrade ejaculation.
Other risks include bleeding (about 2 percent require transfusion), urinary tract infection, urethral stricture (1 to 3 percent), urinary incontinence (under 2 percent), and erectile dysfunction (about 5 to 10 percent of men report new erectile changes, though baseline aging and BPH itself contribute). The procedure does not treat or prevent prostate cancer.
Alternatives and When TURP May Not Be Needed
Many men with mild to moderate BPH respond to medication. Alpha-blockers (tamsulosin, alfuzosin) relax prostate smooth muscle and improve flow within days. 5-alpha-reductase inhibitors (finasteride, dutasteride) shrink the prostate over months. Combination therapy is common for moderate symptoms.
Less invasive office procedures include UroLift (small implants that hold prostate lobes apart), Rezum (steam injection that ablates prostate tissue), and iTind (a temporary nitinol implant). These preserve sexual function and have shorter recoveries but are less durable than TURP. For very large prostates, simple prostatectomy or HoLEP may be preferred. For acute kidney issues from prostatic obstruction, the broader urologic workup may overlap with conditions covered in kidney stone management.
Cost Considerations
Without insurance, TURP typically costs $10,000 to $20,000 in the US, including surgeon, anesthesia, and facility fees. Laser variations may be slightly more expensive due to equipment costs. With commercial insurance, out-of-pocket costs commonly run $1,000 to $4,000 after deductible. Medicare covers TURP for appropriate diagnoses; the procedure has been a Medicare-covered service for decades.

Frequently Asked Questions
Will I be able to have sex normally after TURP?
Erectile function is usually preserved, though about 5 to 10 percent of men report new erectile changes. Retrograde ejaculation occurs in 50 to 75 percent of patients — the orgasm feels normal but little or no semen is released. Fertility is significantly reduced as a result.
How long do TURP results last?
Most men get long-term symptom relief from TURP. About 5 to 15 percent require retreatment within 8 to 10 years, usually because the prostate continues to grow. Repeat TURP or alternative procedures are options if symptoms recur.
How does TURP compare to UroLift or Rezum?
TURP usually achieves the largest improvement in flow rates and is more durable, but causes retrograde ejaculation in most men. UroLift and Rezum preserve sexual function and have shorter recoveries but offer smaller flow improvements and may need retreatment sooner. The right choice depends on prostate size, symptom severity, and how much sexual function preservation matters.
Will I still need BPH medications after surgery?
Most men can stop alpha-blockers and 5-alpha-reductase inhibitors after TURP because the obstruction has been physically removed. Some need to remain on medications for residual symptoms or unrelated conditions like overactive bladder.
The Bottom Line
TURP remains the benchmark surgical treatment for BPH and provides durable symptom relief for most men who undergo it. Useful conversations with your urologist include whether you are a candidate for less invasive options first, what your prostate size suggests for the right procedure, what the expected impact on ejaculation is, and what the surgeon’s complication rates and case volume look like. For men who place high value on preserving ejaculation, the conversation may extend to UroLift, Rezum, or robotic simple prostatectomy.
