I was diagnosed with chronic bacterial prostatitis (CBP) and bladder-neck stenosis.
In 2008, transurethral evaluation and cystoscopy showed dense prostate calcification and fibrosis. My prostate was about 20 g, with a normal digital rectal examination and PSA below 0.7 ng/mL.
I had bladder-neck incision surgery in 2009, but the symptoms returned after about three months. Flomax has not helped.
The only treatment that seems to help is minocycline 50 mg daily. When I stop the antibiotic, the symptoms return.
My urologist has now suggested TURP but has told me it may not solve the problem. I understand there can be complications.
My prostate is small. Can TURP still be performed, and is it reasonable for chronic bacterial prostatitis?
Quick Answer
Yes, transurethral surgery can technically be performed in a man with a small prostate, but prostate size alone does not tell us whether TURP is the right operation.
A prostate of approximately 20 g is not a typical enlarged BPH prostate. In this case, the more important questions are whether there is recurrent bladder-neck obstruction, urethral scar tissue, significant urinary retention, or genuinely documented recurrent bacterial prostatitis.
TURP is not a routine treatment for chronic bacterial prostatitis simply because calcification or fibrosis is present. However, surgery may sometimes be considered when there is a structural obstruction that prevents adequate bladder emptying or contributes to recurrent infection. NIDDK notes that men with chronic bacterial prostatitis may require surgery when urinary retention is caused by obstructing scar tissue. :contentReference[oaicite:1]{index=1}
The fact that symptoms improve on minocycline is clinically interesting, but it does not by itself prove that persistent bacteria trapped inside prostate calcifications are causing every symptom. Ideally, the diagnosis of recurrent bacterial prostatitis should be supported by cultures and the anatomy of the bladder neck and urethra should be reassessed before irreversible prostate tissue is removed.
Because your urologist has already warned that TURP may not solve the symptoms, I would want a very clear explanation of what anatomical abnormality the surgeon intends to correct before proceeding.
What Is Chronic Bacterial Prostatitis?
Chronic bacterial prostatitis is a persistent or recurrent bacterial infection of the prostate.
It often develops gradually and may last for months or years. Symptoms can include:
- burning or painful urination;
- urinary frequency or urgency;
- weak or interrupted urinary flow;
- pelvic, genital or lower abdominal pain;
- painful ejaculation;
- and recurrent urinary tract infections.
NIDDK describes chronic bacterial prostatitis as a bacterial infection that can develop slowly and last a long time, with symptoms that may come and go. :contentReference[oaicite:2]{index=2}
This differs from chronic prostatitis/chronic pelvic pain syndrome , where persistent pelvic symptoms may occur without an ongoing bacterial infection.
How Should Chronic Bacterial Prostatitis Be Confirmed?
This distinction is important before considering surgery.
A clinician generally looks for evidence that bacteria are actually present, usually using urinalysis and urine culture and, in selected cases, additional localization testing.
NIDDK specifically notes that the bacterial forms of prostatitis can be identified through urine testing and culture. The laboratory can identify the organism and help determine appropriate antibiotic treatment. :contentReference[oaicite:3]{index=3}
Antibiotics can have effects beyond killing bacteria, and chronic pelvic pain conditions can naturally fluctuate. Repeated isolation of the same organism makes the diagnosis of recurrent bacterial prostatitis much more convincing.
Is Minocycline a Standard Long-Term Treatment?
Antibiotic selection for chronic bacterial prostatitis should be based, when possible, on the organism identified and its antibiotic susceptibility, while also considering whether the drug reaches therapeutic concentrations in prostate tissue.
NIDDK notes that chronic bacterial prostatitis generally requires a longer antibiotic course than acute infection and that some men with recurrent infection may receive prolonged low-dose treatment. :contentReference[oaicite:4]{index=4}
That does not mean indefinite minocycline is automatically the correct solution. Long-term antibiotic treatment has potential adverse effects and contributes to antimicrobial resistance.
If symptoms repeatedly return after stopping treatment, I would want to know:
- Which bacterium has actually been cultured?
- Has the same organism been found more than once?
- Was antibiotic susceptibility testing performed?
- Are cultures negative while symptoms are still present?
- Could part of the problem be bladder-neck obstruction or chronic pelvic pain rather than persistent infection?
Does Prostate Calcification Cause Chronic Infection?
Prostatic calcifications can be found in men with previous inflammation and sometimes coexist with chronic prostatitis.
However, finding calcification does not automatically prove that bacteria are living inside it or that surgically removing the calcified tissue will cure prostatitis.
This is one of the important corrections to the old answer.
The previous explanation presented a simple sequence: infection → fibrosis/calcification → trapped bacteria → TURP removes the source → infection clears.
Real clinical disease is more complicated than that.
What Does Prostate Fibrosis Mean?
Fibrosis means that scar-like connective tissue has developed.
Inflammation can contribute to tissue remodeling and fibrosis, but the presence of fibrosis inside the prostate does not by itself establish that the urethra is being compressed enough to justify TURP.
The clinically relevant question is whether objective testing demonstrates an obstruction.
Is a 20-Gram Prostate Enlarged?
A prostate of approximately 20 g is generally considered relatively small and is not the kind of enlarged gland typically associated with conventional BPH surgery.
That matters because TURP is most commonly used to remove obstructing transition-zone tissue in men with benign prostatic obstruction.
Ahmed’s case therefore should not be approached as: “The prostate is enlarged, so remove some of it.”
Instead, the question is: “Where exactly is the obstruction, and what operation is most likely to correct it?”
A man can have severe urinary obstruction despite a small prostate if the bladder neck is narrow or scarred. That situation is different from ordinary large-volume BPH and may require a different surgical strategy.
What Is Bladder-Neck Stenosis?
The bladder neck is the opening where urine leaves the bladder and enters the urethra.
If this area becomes abnormally narrow, urine flow may become restricted even when the prostate itself is small.
Symptoms can include:
- weak flow;
- difficulty starting urination;
- straining;
- incomplete bladder emptying;
- frequency or urgency;
- and sometimes urinary retention.
Ahmed already underwent bladder-neck incision, or BNI, and symptoms returned. That history makes reassessing the bladder neck particularly important.
Why Might Symptoms Return After Bladder-Neck Incision?
Several possibilities need to be considered.
- The bladder neck may have narrowed again.
- Scar tissue may have developed elsewhere in the urethra.
- The original obstruction may not have been completely relieved.
- Bladder muscle function may be abnormal.
- Chronic bacterial infection may still be occurring.
- Chronic pelvic pain may coexist with the structural problem.
This is why repeating objective evaluation can be more informative than simply changing from BNI to TURP.
What Tests Could Clarify the Need for TURP?
| Assessment | What It Helps Answer |
|---|---|
| Urinalysis and urine culture | Is there current bacterial infection, and which organism is present? |
| Previous culture review | Has the same bacterial organism repeatedly been isolated? |
| Uroflowmetry | How impaired is the urinary flow? |
| Post-void residual | Is significant urine remaining after voiding? |
| Cystoscopy | Is the bladder neck stenosed again? Is there urethral scar tissue or another visible obstruction? |
| Urodynamic testing | In selected difficult cases, can help distinguish outlet obstruction from weak bladder contraction or other functional problems. |
| Prostate imaging | Confirms prostate anatomy, volume, calcification and other structural findings. |
NIDDK lists urine studies, urodynamic testing, cystoscopy and ultrasound among investigations that may be used in men with prostatitis depending on the clinical situation. :contentReference[oaicite:5]{index=5}
Can TURP Be Done on a Small Prostate?
Technically, yes.
TURP removes prostate tissue through the urethra using an endoscopic instrument. The procedure is not physically impossible simply because the prostate weighs about 20 g.
But that is not the same as saying it is the best procedure.
With a small gland, the surgeon needs a clear reason for removing prostate tissue and must balance the expected benefit against complications.
Is TURP a Treatment for Chronic Bacterial Prostatitis?
Not routinely.
The standard treatment for documented chronic bacterial prostatitis is antibiotic therapy directed at the bacterial infection.
NIDDK states that treatment generally requires a longer antibiotic course and that surgery may be needed when chronic bacterial prostatitis causes urinary retention. Removing obstructing scar tissue in the urethra can improve urinary flow and reduce retention. :contentReference[oaicite:6]{index=6}
That is an important distinction: surgery treats a structural obstruction or complication—it is not a routine method of sterilizing the prostate.
When Could Surgery Make Sense in This Situation?
A procedure becomes more reasonable when objective evidence shows a problem that surgery can actually correct, such as:
- recurrent bladder-neck stenosis;
- significant urethral scar tissue;
- persistent bladder-outlet obstruction;
- substantial post-void residual urine;
- recurrent or refractory urinary retention;
- or recurrent infection clearly associated with poor urinary drainage.
If none of those is present and the main problem is pelvic pain with negative cultures, removing prostate tissue may be much less likely to solve the symptoms.
Why Did the Urologist Say TURP Might Not Solve the Problem?
That is actually an important and responsible warning.
Chronic prostatitis symptoms can involve more than one mechanism. Pain and urinary symptoms may involve:
- bacterial infection;
- bladder-neck obstruction;
- scar tissue;
- pelvic-floor muscle dysfunction;
- nerve sensitization;
- bladder dysfunction;
- and chronic pelvic pain mechanisms.
A TURP can remove obstructing prostate tissue. It cannot guarantee elimination of every source of chronic pelvic pain.
Could This Actually Be Chronic Pelvic Pain Syndrome?
Possibly, either instead of or alongside chronic bacterial prostatitis.
NIDDK describes chronic prostatitis/chronic pelvic pain syndrome as the most common form of prostatitis and notes that it frequently occurs without demonstrable bacterial infection. :contentReference[oaicite:7]{index=7}
Symptoms can include prolonged pain involving the perineum, penis, scrotum, lower abdomen or back, along with urinary symptoms and painful ejaculation.
If cultures repeatedly become negative while symptoms remain, that possibility becomes increasingly important.
A patient with repeated positive cultures plus obstruction is clinically very different from a patient with years of pelvic pain, negative cultures and a normal-flowing urinary tract—even when both have been given the label “prostatitis.”
Why Is Long-Term Antibiotic Use Worth Reviewing?
Long-term antibiotics may sometimes be used for recurrent documented bacterial prostatitis, but prolonged treatment should have a clear clinical reason.
Potential problems include:
- antibiotic resistance;
- gastrointestinal adverse effects;
- drug-specific toxicity;
- alteration of normal bacterial flora;
- and continued treatment of symptoms that may no longer be caused by infection.
With minocycline specifically, prolonged therapy can have adverse effects that deserve monitoring. Ahmed should not stop or alter prescribed therapy based on this page, but the ongoing indication should be periodically reviewed by the treating physician.
What Are the Main Risks of TURP?
The exact risk depends on the procedure, surgeon and patient, but possible complications include:
- bleeding;
- urinary infection;
- temporary difficulty urinating;
- urethral stricture or recurrent bladder-neck scarring;
- urinary incontinence, though persistent severe incontinence is uncommon;
- ejaculatory changes, particularly retrograde ejaculation;
- and less commonly erectile or other sexual problems.
At age 42 with four children, sexual and ejaculatory consequences deserve a specific discussion rather than being treated as an afterthought.
What Is Retrograde Ejaculation?
After some bladder-neck and prostate procedures, semen may travel backward into the bladder rather than exiting through the penis.
The orgasm may still occur, but little or no semen comes out.
This matters particularly for men who may want future fertility.
Ahmed already has four children, but the decision remains personal and should be discussed before any further bladder-neck or prostate surgery.
Dr. Albana’s Perspective
Ahmed, I would not advise you to have TURP simply because your prostate contains fibrosis and calcification.
Your prostate size—about 20 g—actually makes me want to understand the anatomy more carefully, because this is not a typical large-prostate BPH case.
The most important question for your urologist is: What exactly will TURP correct that is causing my current symptoms?
If cystoscopy or other testing demonstrates recurrent bladder-neck obstruction, significant scar tissue or another fixed obstruction associated with poor emptying and recurrent infection, then further surgery may be reasonable.
If urinary flow and bladder emptying are acceptable and cultures are repeatedly negative, I would be much more cautious about assuming that removing prostate tissue will cure chronic pelvic symptoms.
I would also want the history of bacterial cultures reviewed carefully. If the same pathogen repeatedly returns and antibiotic treatment only temporarily suppresses it, that is different from symptoms returning despite sterile cultures.
Because your own urologist has already said TURP may not solve the problem, asking for a second urological opinion before an irreversible operation would be reasonable if you remain uncertain.

Questions to Ask Before Agreeing to TURP
- Is my bladder neck stenosed again?
- Where exactly is the obstruction?
- What is my current urinary-flow rate?
- What is my post-void residual urine?
- Have repeated cultures documented the same bacterium?
- Are my cultures positive when symptoms return?
- What tissue do you intend to remove during TURP?
- Why TURP instead of repeat bladder-neck treatment or another procedure?
- What is the estimated chance that TURP will improve my pain?
- What is the estimated chance it will improve urinary flow?
- What is the risk of retrograde ejaculation in my case?
- Could surgery cause additional bladder-neck or urethral scar tissue?
- If I do not have TURP now, what is the expected risk of waiting?
“Are you recommending TURP to treat documented obstruction, recurrent bacterial infection related to poor drainage, or chronic pain?” Those are different treatment goals and have different probabilities of success.
When to Seek Prompt Medical Care
Seek urgent assessment if chronic prostatitis symptoms are accompanied by:
- complete inability to urinate;
- fever or chills with painful, urgent urination;
- blood in the urine;
- severe worsening lower abdominal or urinary-tract pain;
- or signs of severe systemic illness.
NIDDK specifically advises immediate medical care for these symptoms because acute urinary obstruction or serious bacterial infection can require urgent treatment. :contentReference[oaicite:8]{index=8}
Frequently Asked Questions
Can TURP be performed on a 20 g prostate?
Technically yes, but a small prostate changes the clinical reasoning. TURP should have a clearly defined target such as proven obstruction rather than being performed simply because prostatitis or calcifications are present.
Is a 20 g prostate enlarged?
It is generally considered a relatively small prostate rather than a substantially enlarged BPH gland. Severe urinary obstruction can still occur if the bladder neck or urethra is narrowed.
Does TURP cure chronic bacterial prostatitis?
TURP is not a standard routine cure for chronic bacterial prostatitis. Antibiotics are the principal treatment for documented bacterial infection. Surgery may have a role when an anatomical obstruction or urinary retention needs correction.
Do prostate calcifications trap bacteria?
Calcifications may coexist with chronic inflammation and recurrent prostatitis, but their presence alone does not prove that bacteria are trapped inside them or that surgically removing the calcified tissue will eliminate symptoms.
Why do my symptoms return when I stop antibiotics?
Recurrent bacterial infection is one possibility, particularly if repeat cultures identify the same organism. But symptom recurrence alone does not prove persistent infection. Chronic pelvic pain and urinary obstruction can produce similar symptoms.
Can bladder-neck stenosis recur after incision?
Yes. Scar tissue can recur after bladder-neck treatment in some patients. Repeat cystoscopy, flow testing and residual-urine measurement may help determine whether recurrent narrowing is contributing to symptoms.
Should I get a second opinion before TURP?
A second urological opinion is reasonable when the indication for an irreversible procedure is uncertain, particularly when the prostate is small and the surgeon has already explained that the operation may not resolve the symptoms.
