The prostate gland is a muscular, walnut-shaped gland in men. It is located right below the
bladder
and surrounds the urethra (the tube that carries urine out of the body). It is responsible for making the fluids that carry sperm. As a man ages,
the prostate begins to slowly enlarge and may begin to squeeze the urethra, causing
problems with urination.
The normal adult prostate weighs 18 grams; measures 3cm in length, 4cm in width,
and 2cm in depth. The prostate is composed of approximately 70% glandular elements
and 30% of fibromuscular stroma. Although anatomically divided into different zones,
the prostate is described as having 2 palpable lateral lobes separated by a central
sulcus and one nonpalpable median lobe that may project into the bladder in older
men.
Typical symptoms of include:
- Decreased Stream — Decreased size and strength of urine stream; a weak urine
flow
- Hesitancy— Having a hard time "getting started"
- Intermittence— An "on again, off again" flow of urine
- Incomplete Urination — The feeling that your bladder is not quite empty after
you urinate
- Urinary Retention
— Being completely unable to urinate
- Frequency— Having to urinate much more often than usual
- Urgency— An extremely strong desire to urinate as soon as possible
- Nocturia— The need to get up and urinate in the night
- Incontinence— Being unable to hold back urine until you reach the bathroom
(often accompanied by feelings of urgency)
2.1 Microwave (TUMT)
Transurethral microwave therapy (TUMT) is an outpatient procedure to treat urinary symptoms caused by an enlarged prostate. With TUMT,
your doctor inserts a small
microwave antenna attached to a flexible tube (catheter) through the tip of your
penis. The catheter extends through the tube that carries urine from your bladder
(urethra) to part of the prostate that's blocking urine flow. TUMT uses an antenna
to emit a dose of microwave energy that heats up and destroys excess prostate cells.
TUMT is one of several alternatives for treating an enlarged prostate, a condition
also known as benign prostatic hyperplasia (BPH). Other
treatments
include medications, transurethral resection of the prostate (TURP), transurethral needle ablation (TUNA),
laser surgery and open prostatectomy.
2.2 Greenlight Laser Prostatectomy
The GreenLight™ Laser Therapy is a treatment
that combines the effectiveness of the traditional surgical procedure known as "Trans Urethral Resection of the Prostate"
(TURP) with fewer side effects.
GreenLight is suitable for most patients
with an enlarged prostate. With over 200,000 procedures performed worldwide, the GreenLight procedure is creating a new standard
of care — a standard that offers freedom from enlarged prostate symptoms.
Most patients
return home a few short hours after the PVP procedure and can return to normal, non-strenuous activities within days.
The GreenLight laser system delivers the ultimate benign prostatic hyperplasia (BPH) solution — free from
urinary
symptoms, free from compromise, free to go!
Benefits of GreenLight
- Rapid urine flow improvement
- Quick return to normal activities
- Virtually bloodless procedure
- Less than 1% reported cases of erectile
dysfunction
- Short to sometimes no catheterization (less than 24 hours in most cases)
- Outpatient procedure in otherwise healthy
patients
- Long lasting symptom relief
Urinary incontinence — the loss of bladder control — is a common and often embarrassing
problem. The severity of urinary incontinence ranges from occasionally leaking urine
when you cough or sneeze to having an urge to urinate that's so sudden and strong
you don't get to a toilet in time.
If urinary incontinence affects your day-to-day activities, don't hesitate to see
your doctor.
In most cases, simple lifestyle changes or medical treatment can ease
your discomfort or stop urinary incontinence.
Treatments and drugs
Treatment
for urinary incontinence depends on the type of incontinence, the severity
of your problem and the underlying cause. Your doctor
will recommend the approaches best suited to your condition. Often a combination of treatments is used.
Treatment options for urinary incontinence range from more conservative approaches,
including behavioral techniques and physical therapy to more aggressive options,
such as surgery.
In most cases, your doctor
will suggest the least invasive treatments first, so you'll try behavioral techniques and physical therapy first and
move on to other options only if these techniques fail.
The success of your treatment
depends most of all on the right diagnosis. Talk to your
doctor about the specifics and possible
complications of any treatment. Ask questions and express concerns to help determine which
treatment is right for you.
Male sexual dysfunction
is one of the most common health problems affecting men and is more common with increasing age. Male sexual dysfunction
can be caused by physical or psychological problems. The June 23/30, 2004, issue of JAMA includes
an article about the various types of male sexual dysfunction and
treatments for them.
MAIN TYPES OF MALE SEXUAL DYSFUNCTION
- Low libido (sexual interest)
- Erectile dysfunction (ED, difficulty achieving or maintaining an erection)
- Premature ejaculation (reaching orgasm [sexual climax] too quickly)
- Delayed or inhibited orgasm
- Physical abnormalities of the penis
CAUSES OF MALE SEXUAL DYSFUNCTION
- Problems in the relationship with the sexual partner can lead to sexual dysfunction
- Lowered levels of the male hormone testosterone (a condition known as
hypogonadism) can cause low libido or ED.
- Certain drugs, such as antidepressants and blood pressure medications, can cause
sexual dysfunction.
- Erectile function can be impaired by a stroke or by nerve damage from diabetes or
surgery.
- Disorders affecting blood vessels, such as atherosclerosis (hardening of
the arteries) and high blood pressure, are risk factors for ED.
- Other possible causes of sexual dysfunction include smoking, obesity,
kidney problems,
depression, anxiety disorders, and alcoholism.
DIAGNOSING MALE SEXUAL DYSFUNCTION
If you think you are experiencing male sexual dysfunction, see your
doctor.
- Your doctor
will ask you to describe the problem and will ask questions to help
determine whether the cause is physical, psychological, or a combination of both.
- A general physical examination, including examination of the penis and testicles,
will be performed, and other tests may be done to evaluate your health.
- Blood tests may be done to determine if there is a hormonal problem contributing
to sexual dysfunction.
TREATING MALE SEXUAL DYSFUNCTION
- For psychological causes of sexual dysfunction, such as relationship problems, counseling,
either individually or as a couple, may be beneficial. Sexual therapy with a therapist
who specializes
in sexual dysfunction may also help.
- Depression or anxiety disorders may need
treatment.
- Any physical problems that may be affecting sexual function should be addressed.
- If a medication is interfering with sexual function, it may be possible to change
or discontinue the medication.
- Prescription medications that treat erectile dysfunction may help a man achieve
and maintain erections.
- Prescription medications
that treat erectile dysfunction may help a man achieve and maintain erections.
- Other non surgical treatments include injections therapy and vacuum erection device.
- Surgery
is indicated when other options fail and consists of inflatable and semirigid
penile implants. Surgery
can be performed on an outpatient basis.
A kidney stone is a hard mass developed from crystals that separate from the urine
and build up on the inner surfaces of the kidney. Normally, urine contains chemicals
that prevent or inhibit the crystals from forming. These inhibitors do not seem
to work for everyone, however, so some people form stones. If the crystals remain
tiny enough, they will travel through the
urinary
tract and pass out of the body in the urine without being noticed.
Kidney stones
may contain various combinations of chemicals. The most common type
of stone contains calcium in combination with either oxalate or phosphate. These
chemicals are part of a person's normal diet and make up important parts of the
body, such as bones and muscles.
A less common type of stone is caused by infection in the
urinary tract.
This type of stone is called a struvite or infection stone. A bit less common is the uric
acid stone. Cystine stones are rare.
Treatments:
Conservative therapy: Most kidney stones eventually pass through the
urinary tract
on their own within 48 hours, with ample fluid intake. Pain medications can
be prescribed for symptom relief. There are several factors which influence the
ability to pass a stone. These include the size of the person, prior stone passage,
prostate enlargement, pregnancy, and the size of the stone. A 4 mm stone has an
80% chance of passage while a 5 mm stone has a 20% chance. The doctor usually asks
you to save the passed stone(s) for testing. (You can catch it in a cup or tea strainer
used only for this purpose.)
Medical therapy: Certain drugs or lifestyle changes can be used to help dissolve
stones. See preventive therapy for more information.
Surgical Therapy: Surgery
may be needed to remove a kidney stone for the following reasons: if it does not pass after a reasonable period of time and causes
constant pain; if it is too large to pass on its own or is caught in a difficult
place; if it blocks the flow of urine, causes ongoing urinary tract infection, damages
kidney tissue or causes constant bleeding. Various surgical options are now available
to patients with kidney stones. Our practice offers all of the latest innovations
in stone
treatment.
Pediatric urology is the diagnosis and treatment of congenital (i.e., present at
birth) and acquired urological conditions and diseases in children. Pediatric urologists
treat conditions of the male reproductive tract (e.g., undescended testicle) and
the male and female urinary tracts (e.g., urinary tract infection).
The urinary tract consists of the organs that filter the blood and form urine (kidneys),
the tubes that carry urine from the kidneys (ureters), the organ that stores urine
(bladder), and the tube that carries urine from the bladder and removes it from
the body (urethra).
The most common condition treated by pediatric urologists is urinary tract infection
(UTI).
Other conditions include the following:
- Abnormally located urethral opening (hypospadias)
- Backup of urine from the bladder into the ureter (vesicoureteral reflux [VUR])
- Bedwetting (nocturnal enuresis)
- Distention of the kidney in utero (antenatal hydronephrosis)
- Ureteropelvic junction obstruction (UPJ obstruction; may cause kidney damage)
Pediatric Urological Examination Most children under the care of a pediatric
urologist are school-aged and younger. UTIs (e.g., cystitis) are most common in
young girls and pediatric urological conditions are usually congenital and treated
at a young age. Conditions such as vesicoureteral reflux and antenatal hydronephrosis
are frequently diagnosed during prenatal ultrasound and hypospadias is usually diagnosed
during infancy.
The pediatric urological examination includes a medical history and a comprehensive
physical examination. A history of symptoms, illnesses, injuries, medications,
prenatal ultrasound, and family history are documented. A urinary catheter
may be inserted into the bladder through the urethra to withdraw urine.
Diagnostic tests include the following:
- Blood tests
- Cystometrogram, which measures bladder pressure at various stages of filling
- Cystoscopy, which is an examination of the bladder and ureter
- Intravenous pyelogram, which is a series of x-rays of the ureter and renal pelvis
taken after injecting a contrast agent
- Magnetic resonance imaging (MRI scan)
- Renal scan
- Ultrasound (to detect blockage in the urinary tract)
- Urinalysis and urine culture (to detect UTI)
- Urodynamic studies, which measure the storage and rate of movement of urine from
the bladder)
- Uroflowmetry, which measures urine flow
- Voiding cystourethrogram (VCUG; used to observe the urinary tract before, during,
and after urination)
Vasectomy is a safe and effective method of permanent male contraception. In the
United States, it is employed by nearly 7% of all married couples and performed
on approximately one-half million men per year, more than any other urological surgical
procedure.
Historically, some men have shied away from vasectomy because they fear pain and
the possible complications. In clinical practice, however, one of the commonest
voiced concerns is that of ‘the needle’ for injection of local anesthetic into and
through the scrotal skin. Efforts to enhance the popularity of vasectomy have led
the Chinese to develop refined methods of no-scalpel vasectomy that minimize trauma,
pain and complications.
Vasectomy reversal is a surgery to undo a vasectomy. After successful vasectomy
reversal, sperm are present in your semen again and you may be able to get your
partner pregnant.
Statistically, five to ten percent of the over 600,000 men in North America who
annually undergo a vasectomy, will choose to have theirs' reversed at some time.
Reasons for reversing a vasectomy can include the loss of a child, a new marriage,
or just a desire to have more children to complete the family.
In recent years, with the development of better techniques and a larger pool of
skilled microsurgeons to perform the reversal, excellent results can be obtained
with a high chance of obtaining pregnancy. Vasectomy reversal is generally carried
out in hospital as an outpatient procedure using a general anaesthetic. Success
rates vary by individual patient and the surgeon. Two techniques may be employed
depending upon the circumstances:
- Reconnecting the vas deferens (vasovasostomy) - the preferred connection, or
- Connecting the vas deferens to the epididymis (vasoepididymostomy) -when no sperm
are identified in the testicular vas deferens.
Keep in mind that ultimately, a vasectomy reversal will be considered successful
when a couple achieves becoming pregnant and giving birth. So there are factors
in the decision to have a vasectomy reversal that also involve the female partner.
