Our kidneys act as filters which constantly flushes out toxins and excess minerals with water in form of urine. Urine contains lots of minerals which may precipitate and form stones. Urine has lots of pro-precipitating agents and anti-precipitating agents. When their balance disturbs due to some disease, stones start forming. These stones may often lead to abdominal pain which is referred to as renal colic. 

What exactly is renal colic? 

Renal or ureteric colic is the term used for typical pain in one side of abdomen in flank region starting from back and radiating forward towards lower abdomen up to scrotum. This is usually associated with nausea, vomiting and urinary discomfort. There may be blood in urine. 

How kidney stones are related to renal colic? 

Kidney stones usually form inside kidney and lies there without causing any pain. But whenever they are dislodged and stuck at mouth of kidney (pelvis) or anywhere in ureter, they block the passage of urine of that kidney. This causes swelling in kidney termed as hydronephrosis. This swelling in kidney causes renal / ureteric colic. This colic is protective phenomenon and tries to push out the stones. Small stones do come out in urine by this natural process. This spontaneous expulsion of small stones is common and many local practitioners used to get credit of it feigning benefit of their medicine. However large stones need some form of intervention to come out. Otherwise, they do harm to kidneys in long term. 

Symptoms of kidney stones along with renal /ureteric colic - 

Most stones which are lying in calyces of kidney are asymptomatic 
Nausea & vomiting 
Frequent urinary tract infections 
Fever with chills 
Foul smelling urine 
Hesitency, frequency and burning in urination 
Blood in urine (urine with a reddish, pink or brownish hue) 
Passage of small stones in urine 
Treatment of renal colic 

Treatment of ureteric/renal stones involves control of symptoms and stone removal. 

Expectant Treatment or Medical Expulsion Therapy: Small stones of less than 4 mm size usually pass on its own and some medicines like alpha-blockers and steroid hasten up their expulsion. Medium size stone (4-6 mm), sometimes passes with aid of these medications. But stones larger than 6 mm usually require intervention. 
Lithotripsy: This method involves breaking of stones by shock waves into small dusty particles which pass through urine on its own. This is usually suitable for stones upto 1.5 cm and lying in kidneys. This is non-operative treatment which can be done on OPD or Daycare basis. 
Ureteroscopy (URS): This method involves entry of very thin semirigid scope through urethra into ureter. Stone is broken by LASER and removed. This involves single day admission and spinal anaesthesia. 
RIRS- Retrograde Intra Renal Surgery: In this method very thin flexible scope in maneuvered through urethra into the upper ureter and pelvi-calyceal system of kidney. Stones in kidney or upper ureter are broken by LASER and removed. This is also done under anaesthesia and requires a day admission. 
Mini- PCNL: This method is suitable for large renal stones. In this technique, a small hole is made into the kidney through back and tiny scope is entered into the kidney. Stones are broken by LASER and removed. This is done under anaesthesia and require two to three days admission.

Renal Colic - Ways it Can Be Treated?

Chronic kidney disease or CKD is the decreased function of the function of the kidney for a minimum of three months or more. In this the end stage renal disease usually refers to the end of the kidney function where the kidneys work for less than 15% of what they are supposed to. The kidneys play a vital role in the human body and if they do not function properly then a person can die. The functioning of many organs depends on the kidneys. However, the main function of the kidneys is to remove the products and regulate blood and water, control blood pressure, promote healthy and strong bones, and produce hormones.

Here are 5 facts about kidney disease you should know about:

1. Causes of the kidney disease: There are two main common causes of the end-stage kidney disease. These are preventable causes. These are diabetes and high blood pressure, but then kidney disease can be caused by other inherited diseases such as infection, trauma or polycystic kidney disease.

2. Serious Stages: The kidney disease has five stages and stage 5 is known as the end stage renal disease; this is the point where patients usually need dialysis or kidney transplant to lead a sane life. The stages of kidney disease are:

Stage 1   Slight kidney disease
Stage 2   Mild decrease in kidney function
Stage 3   Moderate decrease in kidney function
Stage 4   Severe decrease in kidney function
Stage 5   End stage renal disease

3. Detection of the disease: Kidney disease is usually difficult to detect because of the presence of very few symptoms. Age, gender along with the blood test is one way to determine information regarding kidney function. The people who are at a risk of getting kidney disease are:

    Over the age of 55 years
    People who suffer from hypertension and diabetes
    Ethnic groups such as Asians, Africans, Americans, Pacific Islanders and Hispanics

4. Signs and Symptoms: CKD is usually considered to be a silent disease and many people don t know that they are suffering from the disease. The signs and symptoms of the disease are:

    Fatigue and weakness
    Nausea, vomiting and loss of appetite
    Dizziness
    Numbness and headaches in hand and feet
    Frequent urination

5. Renal Replacement Treatment: This is the treatment for the end stage of the kidney disease. Dialysis involves the replacement of some part of the lost function of the kidneys and is usually continued throughout life. There are 2 types of dialysis:

    Hemodialysis: This cleans the blood via an artificial kidney which is hooked to the machine
    Peritoneal Dialysis: This removes the excess water and waste products and cleans the blood of the body by using the peritoneal cavity as a filter. 

5 Facts About Kidney Disease You Should Know

The presence of blood in urine is known as Haematuria. It is categorized under 2 types:

    Macroscopic haematuria, which means the patient has seen blood.
    Microscopic dipstick haematuria, which means blood is identified by urine microscopy or by dipstick testing either in association with other urological symptoms (symptomatic microscopic haematuria) or during a routine medical examination. It has been variably defined as 3 or more , 5 or more or 10 or more Red Blood Cells (RBCs) per high - power field.

Urological and other Causes of Hematuria

    Cancer: Bladder, Kidney and Prostate Cancer
    Stones: Kidney, Ureteric
    Bladder Infections: Bacterial tuberculosis, infective urethritis Inflammation
    Interstitial Cystitis Trauma : Kidney, bladder, urethra, pelvic fracture causing urethral rupture
    Renal cystic disease: (e.g. medullary sponge kidney)
    Other urological causes: Benign prostatic hyperplasia, vascular malformations
    Other medical causes of haematuria: anticoagulation therapy (e.g. asprin, anti platelet therapy) Nephrological Causes: more likely in children and young adults, proteinuria; red blood cell casts.
    Urological investigations: Urine culture, urine cytology, cystoscopy, renal ultrasonography and intravenous Urography and CT Urography.

Management of haematuria depends on the cause as determined by the urologist.

Causes and Treatment for Hematuria

Diabetes is a lifestyle disease that is very prevalent in the current generation. According to a report by the World Health Organisation (WHO), the number of people with diabetes has risen from 108 million in 1980 to 422 million in 2014. The global prevalence of diabetes among adults over 18 years of age has risen from 4.7% to 8.5% from 1980 to 2014. Diabetes should not be taken lightly as it can affect other body organs besides the pancreas, such as the kidneys. Diabetic nephropathy refers to damage to your kidneys caused by diabetes, and may also lead to kidney failure in various cases.

Causes of diabetic nephropathy
Not everyone who suffers from diabetes will suffer from diabetic nephropathy. The main function of the kidneys is to filter waste from your blood. However, this is not always the case. Due to high a concentration of blood sugar caused by diabetes, several blood vessels in the kidney are destroyed, thereby, preventing the kidneys from carrying out its job. Over time, the kidneys may stop working altogether, resulting in kidney failure. If you are diabetic, the probability of you suffering from diabetic nephropathy will increase if you smoke or have high blood pressure or high cholesterol.

Catching it early
Today, diabetic nephropathy is the leading cause of chronic kidney disease in the US and other western countries. Since the symptoms of this condition aren t visible in its early stages, you need to undergo urine tests on a regular basis. If detected early, the effects of diabetic nephropathy can be reversed. Common symptoms of this disease include the following:

Swelling in legs and feet
Detection of albumin in urine
Decline in glomerular filtration rate (GFR)
Elevated arterial blood pressure
What are the treatment options?
Medication to lower the blood pressure is the most commonly prescribed form of treatment suggested by doctors to prevent or slow the damage to your kidneys. There are other lifestyle changes that you may have to undertake in order to keep a check on the condition:

Limit sugar intake and keep blood sugar levels within the target range
Exercise regularly and work towards keeping your heart healthy
Limit protein intake, as it could put extra pressure on your kidneys
Limit salt intake to control blood pressure
Quit smoking and drinking
Diabetes is an unfortunate condition to have to live with. But don t let it bog you down! With these simple lifestyle changes and taking care of your general well-being, you can beat the disease and emerge a winner!

Diabetic Nephropathy - Who is at Risk of Acquiring it?

The bladder is a hollow storage organ that collects urine from the kidneys and stores it until it can be passed out of the body through the urethra during the process of micturition or urination. It has a thin inner lining of cells called urothelial cells and a thick muscular wall, which exerts pressure to push the urine out of the body.

Causes of Bladder Tumors

In most cases, the bladder tumor develops on the inner layer due to a combination of some of the following factors.

1. Hereditary: A strong family history of cancer predisposes a person to cancer.
2. Gender: Men are 3 times more prone for bladder cancer than women.
3. Ethnicity: White people are more prone for bladder cancer black people.
4. Smoking: Smokers develop bladder cancer 2-6 times more frequently than non-smokers. cigarettes contain toxic, carcinogenic substances which reach the kidney and are stored in the bladder, leading to their damage.
5. Occupational hazards: Some workplaces have a higher likelihood of causing bladder cancers, especially dye and rubber industries. The effects can be damaging, and the person may develop cancers years after the exposure has happened.
6. Recurrent bladder infections: In some people, this can also lead to bladder cancer in the long run.

Types of Bladder Tumor

Depending on the extent of the cancerous spread, it can be of two types:

1. Non-muscle-invasive bladder tumors: The tumor spread is limited to the inner part of the bladder (urothelial cells)
2. Muscle-invasive bladder tumor: The tumor has spread to the thick muscular outer layer. This is more advanced and prognosis is poor compared to the noninvasive type.

The most common and diagnostic symptom of bladder cancer is the presence of blood in the urine, known as hematuria. This will be intermittent and happens whenever the tumor bleeding happens. Other symptoms include pain in the lower abdomen and frequent urination.

Diagnosis

From the most noninvasive to the most invasive diagnostic test, these include:

1. Urine microscopy to detect cancer cells in the urine
2. Cystoscopy A tube inserted into the urethra to look into the inner wall of the bladder is highly diagnostic
3. Ultrasound, CT Scan, and biopsy can also be further used to identify severity of the tumor.

Treatment

Once the tumor is diagnosed, treatment would depend on the severity of the tumor. For both invasive and noninvasive tumors, definitive therapy is surgery, known as transurethral resection of the bladder tumor (TURBT). The cancerous bladder tissue is removed through a cystoscope as done for diagnosis. The bladder is then flushed with chemotherapy agent to kill any residual cancer cells in the bladder. This is then followed by BCG vaccine, which is again done 1 to 4 weeks for several months to avoid recurrence. In some cases, radiotherapy may also be included.

Bladder Tumor and Its Common Causes

Blood in urine, medically known as Hematuria is not usually a cause of concern, but it can translate into an adverse condition if left unevaluated. The kidneys and other structures in the urinary tracts such as urethra (tube connecting the bladder to the outer part of the body); bladder (that stores the urine) and ureters (tube joining the bladder to the kidney) are the sources of blood flow to the urine. Hematuria can be accompanied by symptoms such as discharge of tea-colored, brownish-red or pink colored urine due to the presence of red blood cells, traces of which can only be detected under the microscope.

Underlying causes behind this disorder might be

Urinary tract infection is where the bacteria enter the body through the urethra and begin to proliferate in the bladder.
Kidney infections (pyelonephritis) is when bacteria infiltrate into the kidneys from the bloodstream or travel up from the uterus to the kidneys.
A kidney or a bladder stone is marked by the minerals in the concentrated urine precipitating out and molding into crystals that deposit on the bladder or kidney walls.
Enlarged prostate is a condition in which the prostate gland, that is situated just below the bladder surrounding the upper part of the urethra, starts growing as males head towards their middle age.
Kidney disease such as glomerulonephritis causes swelling of the kidneys, thus disrupting the filtering system.
Bladder, kidney and prostate cancer are also possible causes.
Hereditary disorders such as sickle cell anemia (a hereditary disease of the red blood cells in the hemoglobin) can also pose as a cause behind this disorder.
Kidney injury as a result of heavy blows, accidents or injuries sustained while playing a spot can also contribute to this condition.
Medications such as penicillin or the anti-cancer drug  cyclophosphamide 
Strenuous physical exercises like intense workout or running may also result in Hematuria.
Treatments
There is no fixed cure for Hematuria; instead the doctor would work on treating the repressed conditions behind the symptoms, such as prescribing antibiotics to heal the urinary tract infection or a medicine to shrink and normalize the enlarged prostate or administer a shock wave therapy to destroy the kidney or bladder stones.
