Аденома простаты, новые способы уменьшения железы. Обзор недостатков и преимуществ всех методов
Main summary
Key takeaways
Main ideas / lessons
-
Purpose of the talk: The speaker explains non-radical / minimally invasive ways to reduce prostate enlargement (BPH/“adenoma”) and improve urinary symptoms, with a focus on maintaining sexual function for men who are sexually active.
-
Why it’s needed: With age, prostate size increases and can worsen quality of life and urinary symptoms, such as:
- frequent urination
- nighttime urination
- weak urine stream
- difficult urination
-
Problem with “information overload”: Online marketing and clinic websites often highlight only advantages, making it hard for patients to choose a method.
-
Treatment philosophy: “Gentle” methods aim to improve symptoms without radical tissue removal, but may have:
- temporary effects, and/or
- a higher chance of recurrence compared with surgery.
-
Structure of the video: This segment covers the first five methods (gentler options). A later segment will cover more radical approaches (laser technologies and laparoscopy).
Method-by-method: pros, cons, and key concepts (first five methods)
1) Permanent/long-term prostatic stent (example: “Mi-Macat” spiral stent)
Concept
- A spiral stent made from nitinol (nickel-titanium shape-memory alloy) is implanted to keep the urethral passage open.
- It can be positioned in the prostate/urethra (and is also described as usable in the ureter).
Pros
- Potentially non-surgical and bloodless.
- Can restore urine flow by expanding the narrowed passage.
Cons / limitations
-
Stent migration (shift): If the stent moves away from its intended location, the intended effect can be lost.
-
Constant pressure on tissue: Ongoing pressure may disrupt microcirculation, leading to pressure sores, then infection and scarring.
-
Encrustation: Salt/stone buildup can:
- block the stent (stop working), and
- make removal difficult.
Bottom line
- Promising, but real-world drawbacks limit its widespread use.
2) Temporary nitinol stents (example: “Mika-Atin” stents)
Concept
- Similar shape-memory stent material, implanted temporarily (average duration stated: ~5 days).
- Intended to expand the urinary passage lumen.
Pros
- Minimally invasive.
- Can provide a temporary improvement in urinary flow.
Cons / limitations
-
Does not reduce prostate size: It mainly “pushes apart” the lumen temporarily.
-
Short-lived benefit: Symptoms relief tends to be brief.
-
Positioned as palliative care, especially when:
- an operation is not possible (for example, due to health constraints).
Bottom line
- Useful for selected patients, but not ideal as a universal long-term solution.
3) Prostatic urethral “lift” / retractor implant (called “Ralif” in subtitle text)
Concept
- A permanent implant placed like a “retractor” analogy:
- “stitches through” prostate thickness
- creates/increases the urethral lumen channel.
Pros
-
Preserves ejaculation: No retrograde ejaculation; semen exits normally.
-
Can improve “descent/quality” (interpreted as sexual function-related quality).
- Minimally invasive.
- Can be performed transurethrally.
- Notes possible subsequent procedures if needed (e.g., Aquablation after revision/assessment).
Cons / limitations
-
Size limitation: Indicated only for prostates up to ~70 cm³.
-
Often temporary effect: Average duration stated: ~3 years.
-
Reason: The adenoma remains and can continue growing, eventually overgrowing/pressing on the implant—leading to symptom return and possible re-intervention.
Bottom line
- Effective for selected prostate sizes and patients prioritizing sexual function, but not definitive shrinkage.
4) Water vapor ablation / vapor thermoablation
Concept
- Minimally invasive access through the urethra (no incisions or direct punctures through urine).
- A needle is used to deliver high-temperature water vapor into the prostate.
- This causes tissue necrosis/cell death in adenoma tissue, reducing effective volume and improving symptoms.
Pros
- Bloodless: no direct cutting/removal of adenoma tissue.
- Preserves ejaculation and erectile function (as claimed by the speaker).
- Potentially outpatient.
- Less need for deep anesthesia.
- Execution time stated: ~10–15 minutes.
- Symptoms can decrease and urine flow improves.
Cons / limitations
-
Volume limitation: Mentioned as needing a more “methodical” approach (specific criteria not fully clarified).
-
Delayed effect: Adenoma volume does not shrink immediately. Time to effect: ~3 weeks to 3 months.
-
Non-radical → relapse risk remains: Remaining tissue may regrow.
-
Evidence mentioned:
- A 2022 study on re-intervention/re-operation after initial results: ~47%. The speaker notes this is a minority overall and interprets that most patients still do better, while emphasizing that long-term outcomes beyond early years (method used ~5 years) are still being established.
Bottom line
- Good minimally invasive option, but results are not immediate, and recurrence remains possible.
5) Prostatic embolization (arterial method)
Concept
- Performed under local anesthesia, commonly via the femoral artery.
- Feeding arteries are visualized using contrast.
- Microspheres (micro-EMs) are placed into arteries supplying the prostate.
- Blood supply is blocked → prostate tissue becomes ischemic → atrophy and size reduction.
- The bladder neck is not targeted, and adenoma tissue is not directly removed.
Pros
- No general anesthesia required (local anesthesia).
- Works for any prostate size (as claimed by the speaker).
- Preserves ejaculation, because the bladder neck is not affected.
- Improves urination by reducing prostate size.
Cons / limitations
- Complication risks (from literature):
- microsphere thrombosis could impair nearby structures (e.g., bladder wall, penis, rectum).
- Speaker’s quantified risk:
- serious complications described as about ~1–4%.
- Possible temporary side effects:
- perineal pain
- burning/discomfort when urinating
- urethral discomfort
- Non-radical → recurrence possibility remains (adenoma not removed).
- Evidence mentioned:
- Two publications (2014–2018 timeframe referenced in subtitles) suggest ~9–20% of patients needed repeat surgical treatment within the first 2 years (example given: TURP).
- Also discussed as suitable for seriously ill patients who can’t tolerate surgery (palliative role).
Bottom line
- Strong minimally invasive approach with broad applicability, but not a “cure-all” due to recurrence risk and non-radical nature.
Overall comparison / concluding points
- The speaker frames these five methods as gentler alternatives to surgery:
- often aiming to preserve sexual function,
- but frequently being temporary or non-radical, meaning re-intervention/relapse remains possible.
- The next part of the series will cover more radical options, including laser technologies and laparoscopy, with comparisons such as enucleation vs laser vaporization.
