Symptoms Of Kidney Stones

Many patients with small kidney stones do not display any symptoms throughout their lifetime.

In these cases, kidney stones are very small, and they eliminate without symptoms when patients urinate. However, when symptoms start to appear, they usually include pain, blood in the urine, and nausea with or without vomiting.;

Pain triggered by kidney stones is often located on the affected side of the spine, below the ribcage, which is why it is described as flank pain.

The nature of the pain is variable, and it often irradiates to the groin, testicles, labia majora, or the legs. It is a very intense pain, and it is often accompanied by profuse sweating, nausea, and vomiting.;

Not every case of kidney stones includes blood in the urine as a symptom. However, it is an important sign that the stone is passing through the urinary tract.

Other symptoms include a burning sensation while urinating and fever, especially when theres a urinary tract infection associated with an injury to the inner linings of the urinary tract .;

If you see a lot of older male patients, its likely that youve often had a conversation about the ocular effects of Flomax , an oral medication for men who suffer from benign prostatic hypertrophy . Flomax, an alpha-1a blocker, decreases symptoms of BPH such as frequency, urgency, weak urine stream, difficulty in starting urine flow, dysuria and nocturia.

The decrease in BPH symptomatology observed with tamsulosin is directly related to the drugs ability to preferentially antagonize alpha-1a receptors and, therefore, relax smooth muscle in the prostate and bladder neck. Although other non-subtype alpha-1 blockers exist, tamsulosins affinity and selectivity for the alpha-1a receptor subtype results in superior efficacy in treating BPH without the hypotensive side effects common with less selective agents.1 Unfortunately, it also relaxes the iris dilator muscle, leading to miosis.

In recent years, the use of tamsulosin has expanded to off-label indications in both men and women. Here is an overview.;

Off-Label UsesThe most common off-label use of tamsulosin is to assist in the passage of kidney stones by increasing urinary fluid volume and pressure as well as relaxing smooth muscle in the ureters.2 Studies have verified that tamsulosin increases the expulsion rate of kidney stones while decreasing the time to expulsion and the need for adjunctive pain management, hospitalization and surgical intervention.3

Small Kidney Stones Usually Pass On Their Own

Small kidney stones are defined as being less than 5mm in size. These stones are normally able to pass through the urinary tract on their own.;Depending on the circumstances, it is generally safe to wait as long as four to six weeks for a small kidney stone to pass out of the body. However, if an infection develops, or urine flow becomes blocked, intervention will be required.

Studies have evaluated the use of tamsulosin in patients with acute renal colic.

The results show that patients receiving tamsulosin in the emergency room have a lower requirement of pain medication and anesthetics. They also have a significant reduction in their hospital stay and lower the need for surgical removal .

These results of applying Flomax in the treatment of kidney stones may even lead to an estimated reduction of 29% in frequency of visits to the emergency department and a 24% reduction in healthcare expenses .;

The 2016 American Urological Association guidelines for the management of stones indicates that alpha-blockers may be beneficial for stones that are less than 10mm.; However, research is not conclusive on the use of tamsulosin in the treatment of kidney stones.

How Does Flomax Work for Kidney Stones?

Question: I’m a 38-year-old woman who recently went to the hospital for left-side pain that turned out to be a 4mm kidney stone. What was surprising was that the doctor in the emergency room sent me home with a prescription for Flomax to help the stone pass.


I’m a 38-year-old woman who recently went to the hospital for left-side pain that turned out to be a 4mm kidney stone. What was surprising was that the doctor in the emergency room sent me home with a prescription for Flomax to help the stone pass.

When I went to fill the prescription, my insurance plan wouldn’t pay for it because I’m a woman and Flomax is only FDA-approved for treating a man’s prostate. The stone eventually did pass without the Flomax, but have you ever heard of using it for kidney stones?

Answer: Yes. Doctors are now using the male prostate drug Flomax to aid in the passage of kidney stones – even in women. While it’s not approved by the Food and Drug Administration for that use, it’s a widely used and proven kidney-stone treatment.

At least nine clinical trials in the literature show that beyond the usual advice of increasing fluid intake and straining the urine to capture the stone, Flomax and the calcium-channel blocker blood pressure drug nifedipine decrease the spasm of smooth muscle cells lining the junction where the two kidney ureter tubes connect with the bladder, aiding in the passage of kidney stones.

Whats The Urinary Tract How Does It Work

Your urinary tract is vital to your body because it gets rid of waste and extra fluid. Its made up of both your kidneys, two ureters, your bladder and your urethra. Each organ has an important job :

  • Kidneys: Your fist-sized, bean-shaped kidneys are located on either side of your spine, below your rib cage. Each day they filter 120 to 150 quarts of your blood to remove waste and balance fluids. Your kidneys make one to two quarts of urine every day.
  • Ureters: After your kidney creates urine, the liquid travels through the tube-shaped ureter to the bladder. There is one ureter per kidney. Kidney stones can pass through the ureters or, if theyre too big, get stuck in them. You may require surgery if the stone is too large.
  • Bladder: Between your hip bones is your bladder, an organ that stores urine. It stretches to hold about one and a half to two cups.
  • Urethra: Like a ureter, your urethra is a tube through which urine passes. Its the final stop of the urinary tract where your urine leaves your body. This is called urination.
