Botox for Enlarged Prostate-Mayo Clinic

Urinary problems caused by BPH are known as lower urinary tract symptoms, or LUTS. Men with LUTS often have problems in the bedroom.

The link between LUTS and sexual problems is not fully understood. But many of these men have a lowered sex drive, trouble maintaining an erection, and theyâre less satisfied with sex. Depression, loss of sleep due to frequent nighttime trips to the toilet, or some related physical cause may play a role.

Whatever the reason, the worse LUTS get, the more trouble a man may have in the bedroom. LUTS can be treated, so see a doctor early, before the symptoms cause a bladder problem or begin to spoil your sex life.

Population Standard Error Of The Mean

Let us consider our 301 prostate volumes as a population. The mean of the 301 volumes becomes the population mean =36.47;ml and the standard deviation =18.04;ml. If we randomly draw prostate volumes, they will generally be somewhat different from one another, and these differences will follow some frequency distribution; is the standard deviation of this distribution. Similarly, if we calculate means m1, m2, , from repeated samples, they will generally be somewhat different one from another and will follow some frequency distribution; the SEM is the standard deviation of this distribution. It is often symbolized as m. It will be smaller than , because it reflects the behavior of 301 observations rather than 1. It turns out that

Large Prostate With Few Symptoms

Patients with very enlarged prostates may have few symptoms or mild symptoms. Doctors verify that there are no problems with kidney or bladder function. If not, they know that the enlarged prostate is not harming the body. In this case, doctors may recommend just watching the prostate or doing non-surgical treatments. Options include changing certain eating and drinking habits and urinating less often. Patients can take medications that relax the prostate, such as tamsulosin, or shrink the prostate, such as finasteride or dutasteride. Patients also may try supplements like saw palmetto to help their symptoms.

Anatomy Of The Prostate

The prostate is a small;gland;in the male reproductive system. It is situated in front of the;rectum, below the;bladder, and surrounds the;urethra, which is the tube through which;urine;flows out of the body. The main function of the chestnut-sized prostate is to secrete part of the;seminal fluid;that combines with sperm to form;semen.

Requirements For Normal Voiding


1.Average Bladder Capacity 350-550 cc.

In the elderly, the capacity may decrease to 250 – 300 cc. Approximately 150-250 cc may be stored before there is a sensation of bladder pressure. As the bladder fills beyond 150-250 mL the individual begins toilet seeking.

2. Anatomical integrity of the bladder, urethra and external sphincter.

The bladder and external sphincter actvity must be coordinated to store and release urine. The healthy bladder muscle is stable and does not contract until the person relaxes the external sphincter. Post void residual of 50 to 100 mL is generally accepted as normal in the elderly. The literature suggests that younger people empty their bladder every 4 to 5 hours and older people empty their bladder every 3 to 4 hours within a 24 hour period.

Does Bph Increase Your Risk Of Developing Prostate Cancer

Based on research to date, the answer is no. However, BPH and prostate cancer have similar symptoms, and a man who has BPH may have undetected cancer at the same time.

The American Cancer Society recommends that men make an informed decision with their health care provider whether to be screened for prostate cancer. For men at average risk, this discussion should start at age 50. They also say that for men who are at high risk, such as African-American men and men with a family history of prostate cancer, screening should be considered at age 45. Men at an even higher risk, such as having more than one relative with a history of prostate cancer at an early age, should consider earlier testing.

The American Urological Association recommends against routine screening for men age 40 – 54 who have an average risk of prostate cancer. Those with a higher risk are encouraged to discuss prostate cancer screening tests with their doctor. The association recommends that men ages 55 – 69 should weigh the risks and benefits of screening and treatment. For those who choose screening, the AUA suggests that they may be screened every two years rather than annually. Tests used to screen for prostate cancer include a blood test for a substance called prostate-specific antigen and the digital rectal exam . The AUA does not recommend PSA screening in men over age 70 or any man with less than a 10-15-year life expectancy.

Bmi Body Fat And Metabolic Markers

There was no association between body mass index and prostate size , nor were men with a BMI above the median more likely to experience BPH , controlling for age . Likewise, body fat percentage was not associated with prostate volume , or BPH , controlling for age and height. Neither systolic nor diastolic blood pressure was associated with prostate volume or BPH , nor were individuals with high systolic or high diastolic blood pressure more likely to have larger prostates or BPH , controlling for age and height. However, men with higher HbA1c had larger prostates and trended towards presentation with BPH controlling for age and height. Men with HbA1c greater than 6% trended toward a higher likelihood of BPH , controlling for age and height.

The prostate is a walnut-sized organ that is part of the male reproductive system. It sits in front the bladder and above the rectum. The prostate is responsible for the production and supply of fluid that helps nourish sperm in the ejaculate. The urethra, where urine travels from the bladder to the penis, runs through the prostate.

As a result of family history, lifestyle, diet, and natural hormonal changes, the prostate begins to grow in size as men age, starting in their mid-30s. When the prostate becomes more enlarged over time, it might press against the urethra and block urine flow . This condition is called benign prostatic hyperplasia, or BPH.

Enlarged prostates differ in size. The size can be estimated on digital rectal exam or prostate imaging like an ultrasound. People with very enlarged prostates have several treatment options. However, size is not the only factor used to choose a treatment.

When doctors evaluate the prostate, symptoms are just as important as size. In addition, size and symptoms don’t always correspond. For example, one person might have a mildly enlarged prostate with noticeable symptoms, while another person could have a very large prostate with no symptoms.

All of this information is the basis of a personalized treatment plan. Here are the options for patients with very enlarged prostates, with or without symptoms.

The next step was to examine differences in individual prostate dimensions according to the method used to obtain them. We compared each dimension estimated by ultrasound prior to surgery vs. the same respective prostate dimensions measured post-surgery from our initial cohort of 153 patients. This comparison is shown in Fig.;. We observed that the mean length of the prostate was overestimated by 10.8% using ultrasound . The mean height was overestimated using TRUS by 11.1% . Finally, the width of the gland estimated by TRUS was fairly similar to the measured value .

Generations Of Men Underwent Prostate Cancer Tests During An Aggressive Screening Regimen Then The Screenings Stopped Now Doctors Are Reevaluating Just How Worried Men Should Be About Their Prostate

by Michael J. Mooney

Its tucked deep within the body, nestled between the bladder and penis, an elusive gland roughly the size of a Ping-Pong ball. Many people dont know what, if any, purpose the prostate serves most of what we hear about it revolves around the problems it can cause, especially later in life. But without it, there might not be any life at all.;

In some ways, the male prostate gland is equivalent to the female mammary glands. Mammary glands are responsible for nourishing a child in the early stages of life; the prostate is responsible for protecting the sperm even earlier. It does this by producing an enzyme called prostate-specific antigen , which liquefies the semen, essentially freeing it from the seminal coagulum. PSA also gets credit for neutralizing the cervixs blocking enzyme, which allows sperm to freely enter the uterus and, hopefully, penetrate the egg.;

The prostate gland, small as it is, is like a multifaceted diamond: every time you look at it from a different angle, under a different light, you see a different aspect of it, find a new scientific challenge, unresolved mysteries, says urologist Dr. Claus Roehrborn, who specializes in prostate diseases and has chaired the University of Texas Southwestern Medical Center Department of Urology since 2002. His work is at the forefront of current innovations in treating and diagnosing prostate cancer.;

Symptoms Of Prostate Cancer: What Are The Symptoms For Prostate Cancer

Usually, prostate cancer does not produce symptoms by itself until it is fairly advanced. Prostate cancer arises silently and usually passes through a curable stage into an incurable stage silently. Therefore, the only means of detecting it when it is curable is to actively look for it with screening. Symptoms could include urinary difficulties ; however, these symptoms are usually caused by benign enlargement of the prostate. However, these symptoms are usually caused by urinary obstruction from benign prostatic enlargement,scar tissue or from inflammation. Bone pain occurs in very advanced prostate cancer, but the aches and pains that most people experience are usually caused by arthritis.

Case Presentation

A 67-year-old male is seen in the Emergency Department for urinary retention. He has a history of moderate lower urinary tract obstructive and irritative symptoms consisting of frequency, urgency, poor force and caliber of his urinary stream, and nocturia. In the last few days prior to his admission to the hospital, he had dribbling of urination and lower abdominal pain. A physical exam revealed a bladder palpable above the pubic symphysis, the rectal exam revealed a markedly enlarged prostate gland, and a urinalysis revealed 5-7 white blood cells/high power field. The patients prostate-specific antigen was 6.5 ng/mL. The blood urea nitrogen was 40 mg/dL, and serum creatinine was 2.6 mg/dL. An abdominal ultrasound revealed hydroureteronephrosis with a markedly distended bladder. A Foley catheter was inserted, and he had approximately 900 cc of residual urine. He experienced a post-obstructive diuresis with normalization of his BUN and creatinine levels. A cystoscopy revealed coaptation of the lateral lobes of the prostate and grade 3 trabeculation of the bladder. The patient had GreenLight laser treatment of his outlet obstruction and used a catheter for 3 days after the procedure. He was able to void with a good stream and had less than 75 cc of post-void residual. Follow-up BUN and creatinine levels 3 weeks after the GreenLight laser procedure were 15 mg/dL and 1.7 mg/dL.

Treating Enlarged Prostate With A Weight Of 105 Gram

QUESTION: I am 65 years old. I got my ultrasound yesterday. The weight of my prostate was 105 gram.


  • Other important thing in here is that the only way to reduce the size and the weight of your prostate is surgery. There are several surgical procedures like Trans Urethral Resection of the Prostate , Trans Urethral Needle Ablation and others. During these procedures an instrument is situated on the prostate thru the urethra and this instrument is cutting of a piece of your prostate.
  • Furthermore, there are several medications used for the treatment of enlarged prostate. These drugs are Alpha blocker and 5-alpha reductase inhibitors, which are used to reduce partially the size of the prostate and to remove the symptoms. However, you have to know that these drugs are prescribed only by qualified specialist, because there are affecting the cardio-vascular system, which limits the use of them if the patient is having problems with the blood pressure or with the heart.
  • Relationship Between Measured And Estimated Prostate Volumes

    The estimated volume from TRUS imaging assumes an ellipsoid geometrical shape of the prostate using the formula . In order to identify the best coefficient for this series of 153 fresh prostate specimens, we used the measured prostate weight converted to measured prostate volume by using 1.02g/cc as the density, as defined above. Thus, the mean measured volume of our cohort was 48.1cc .

    Measured prostate volumes along with TRUS-obtained prostate dimensions were then used to calculate a new coefficient from the rearranged algebraic formula: Coefficient=V/L x H x W, where L, H and W were all obtained by TRUS, and V is the measured prostatic volume of fresh prostates, obtained just after surgery, as mentioned above. This calculation was performed for each of the 153 prostates, which led to a calculated mean coefficient of 0.66.

    Linear regression plots were created in order to compare the newfound coefficient of 0.66 with the ellipsoid coefficient of 0.52. Figure;a shows that plotting estimated prostate volumes against measured prostate volumes using 0.66 as a coefficient yielded an equation of y=0.892x+8.8829 with an R2 value of 0.42 . By performing the same analysis using 0.52 as the coefficient, the equation generated was y=0.5652x+13.028 with R2=0.32 .

    How Is Bph Diagnosed

    After evaluating your medical history and giving you a complete physical, your doctor will perform a digital rectal examination.

    Because the prostate gland is in front of the rectum, the doctor can feel if the back of the gland has any abnormalities during this examination. This enables the doctor to estimate the size of the prostate and to detect any hard areas that could be cancer.

    Several studies may be done to help diagnose your condition:

    • A urine test called a urinalysis
    • A seven-question BPH Symptom Score Index survey to evaluate the severity of your symptoms
    • A flow study to see if the urine stream is slow compared with normal flow
    • A study to detect how much urine is left in the bladder after urination

    How Many Grams Is An Enlarged Prostate


    The mean weight of the normal prostate in adult males is about 11 grams, usually ranging between 7 and 16 grams. The volume of the prostate can be estimated by the formula 0.52 ×length× width ×height. A volume of over 30 cm3 is regarded as prostatomegaly .

    Secondly, how do you reduce the size of an enlarged prostate? To help control the symptoms of an enlarged prostate, try to:

  • Limit beverages in the evening.
  • Limit caffeine and alcohol.
  • Go when you first feel the urge.
  • Schedule bathroom visits.
  • Urinate and then urinate again a few moments later.
  • Also to know is, what is enlarged prostate size?

    Enlarged prostate. The prostate gland surrounds the urethra, the tube through which urine passes out of the body. An enlarged prostate means the gland has grown bigger. Prostate enlargement happens to almost all men as they get older. An enlarged prostate is often called benign prostatic hyperplasia .

    At what size of prostate requires surgery?

    For patients with prostate glands larger than 80 grams, an open prostatectomy is performed. After the surgeon makes an incision from the navel to the pubic bone, the bladder is opened and tissue of the prostate is removed.

    Know Your Prostate Size

    Since everyone is different, it should be no surprise that every mans prostate is a different size.; Heres why it can matter and how it can help to know: What IS surprising to me after over a decade as an advocate, and on a Helpline, is that most men dont know what size their prostate is, and most men are never even told.

    SCREENING For men who are PSA testing and screening for prostate cancer, it is very helpful to know how large or small your prostate is because it bares on how much PSA you should be making.; I have seen different experts use different formulas, but in simple terms, a 60cc prostate should make twice the PSA of a 30cc prostate.; I know there is an age-specific PSA, but honestly, it is based on the reality that a prostate gets larger as you get older, but if thats the case, why not find out what size it really is?; Ive had a couple of Helpline callers in their 70s one with a 17 cc prostate and the other with a 200 cc prostate.; And, yes they were both in their 70s.; So how does age-specific PSA work for them?; So ask your urologist for a number What is the size of my prostate?; This may be an estimate, but that is still helpful.; An urologist can estimate on DRE , and if youve ever had a biopsy, there is an ultrasound report from the biopsy that has a measurement and should have a number a prostate volume or size.; Ask for it.
