colic is among the most severe pains the human body produces. It arrives suddenly, peaks within an hour or two, comes in waves, and leaves people unable to find any position that helps.

A stone that leaves the kidney and lodges in it blocks the flow; pressure builds behind the obstruction, and it is that pressure \u2014 not the stone scraping \u2014 that produces the pain. Stones tend to stick at three narrow points: where the kidney joins the ureter, mid-way, and at the entry to the bladder, which is the tightest of the three.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Where the pain travels gives a rough hint about where the stone is \u2014 loin pain radiating to the testicle suggests a stone higher up, pain going into the groin suggests one lower down, and a stone right at the bladder entrance often causes urgency and a burning sensation that gets mistaken for a urinary infection. It is only a hint, not a diagnosis; the imaging decides.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img data-recalc-dims=\"1\" decoding=\"async\" width=\"800\" height=\"533\" data-attachment-id=\"4184\" data-permalink=\"https:\/\/drsoaraweeurology.com\/my\/2021\/09\/24\/ureteric-stone-pain-management\/salt-in-shape-of-kidney-on-dark-floor\/\" data-orig-file=\"https:\/\/i0.wp.com\/drsoaraweeurology.com\/wp-content\/uploads\/2021\/09\/Salt-kidney.jpg?fit=1200%2C800&amp;ssl=1\" data-orig-size=\"1200,800\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;8&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;Canon EOS 5D Mark III&quot;,&quot;caption&quot;:&quot;salt in shape of kidney on dark floor&quot;,&quot;created_timestamp&quot;:&quot;1605279479&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;50&quot;,&quot;iso&quot;:&quot;125&quot;,&quot;shutter_speed&quot;:&quot;0.008&quot;,&quot;title&quot;:&quot;salt in shape of kidney on dark floor&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"Ureteric stone always be the consequence from falling down kidney stone.\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;Ureteric stone always be the consequence from falling down kidney stone. &lt;\/p&gt;\n\" data-large-file=\"https:\/\/i0.wp.com\/drsoaraweeurology.com\/wp-content\/uploads\/2021\/09\/Salt-kidney.jpg?fit=800%2C534&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/drsoaraweeurology.com\/wp-content\/uploads\/2021\/09\/Salt-kidney.jpg?resize=800%2C533&#038;ssl=1\" alt=\"Diagram of a kidney stone descending into the ureter \u2014 a ureteric stone begins as a kidney stone that drops into the ureter\" class=\"wp-image-4184\" srcset=\"https:\/\/i0.wp.com\/drsoaraweeurology.com\/wp-content\/uploads\/2021\/09\/Salt-kidney.jpg?w=1200&amp;ssl=1 1200w, https:\/\/i0.wp.com\/drsoaraweeurology.com\/wp-content\/uploads\/2021\/09\/Salt-kidney.jpg?resize=300%2C200&amp;ssl=1 300w, https:\/\/i0.wp.com\/drsoaraweeurology.com\/wp-content\/uploads\/2021\/09\/Salt-kidney.jpg?resize=1024%2C683&amp;ssl=1 1024w, https:\/\/i0.wp.com\/drsoaraweeurology.com\/wp-content\/uploads\/2021\/09\/Salt-kidney.jpg?resize=768%2C512&amp;ssl=1 768w, https:\/\/i0.wp.com\/drsoaraweeurology.com\/wp-content\/uploads\/2021\/09\/Salt-kidney.jpg?resize=18%2C12&amp;ssl=1 18w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">A ureteric stone is a kidney stone that has dropped into the ureter and lodged there.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What Genuinely Helps Before You Are Seen<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>An anti-inflammatory painkiller (NSAID) is the most effective simple option<\/strong> \u2014 more effective than paracetamol for this particular pain, because it lowers the pressure in the obstructed system as well as relieving pain. But NSAIDs are not harmless, and in ureteric colic several of the cautions apply at once. <strong>Do not take one<\/strong> if you have kidney impairment, an ulcer or previous gastrointestinal bleeding, asthma that is worsened by these drugs, heart failure, or if you are pregnant \u2014 and be careful if you take a blood thinner, or blood pressure medication of the ACE-inhibitor or diuretic type, where the combination with dehydration can injure the kidneys. If you are dehydrated from vomiting, that is itself a reason to be cautious and to be seen rather than to dose yourself further. Paracetamol is the fallback where NSAIDs are unsuitable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A warm compress or hot shower over the loin<\/strong> genuinely eases the muscle spasm for some people and carries no risk.

For the prevention side, which is where fluid genuinely earns its reputation, see <a href=\"https:\/\/drsoaraweeurology.com\/2020\/06\/19\/8-good-habits-for-the-prevention-of-kidney-stones-formation\/\">the eight habits that prevent kidney stones<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One more thing not to do: <strong>do not strain and then discard<\/strong>.

Low-dose protocols are used where possible, since the radiation is not nothing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Two exceptions matter: <strong>in pregnancy and in children, ultrasound is used first<\/strong>, to avoid radiation. Ultrasound is also a reasonable first look in anyone with a known stone history \u2014 it shows whether the kidney is swollen even when it cannot see the stone itself \u2014 but it is not accurate enough to plan a procedure around.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Size is what most often decides the plan: small stones frequently pass on their own with time and pain control, sometimes helped by medication \u2014 covered in <a href=\"https:\/\/drsoaraweeurology.com\/2021\/10\/01\/medical-ureteric-stone-expulsive\/\">medical expulsive therapy<\/a> \u2014 while larger ones, or any stone in an infected or non-functioning system, are dealt with actively. The options are set out in <a href=\"https:\/\/drsoaraweeurology.com\/services\/kidney-stone-treatment-bangkok\/\">kidney stone treatment<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What does ureteric stone pain feel like?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Sudden, severe, one-sided loin pain that peaks within an hour or two and comes in waves, usually with nausea or vomiting and an inability to keep still. It may travel to the testicle if the stone is higher up, or to the groin if it is lower; a stone at the bladder entrance often causes urgency and burning that gets mistaken for a urinary infection. The location of the pain is a hint, not a diagnosis.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When is ureteric stone pain an emergency?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Above all, fever or chills with flank pain \u2014 a blocked kidney that is also infected can become life-threatening within hours and needs urgent drainage, because antibiotics cannot sterilise urine trapped behind a stone. Also: vomiting that prevents keeping fluids down, passing little or no urine, having only one or a transplanted kidney or known kidney impairment, pregnancy, and pain that simple painkillers do not control. Attend an emergency department or call 1669 in Thailand.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does drinking a lot of water help pass a stone during an attack?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No \u2014 this is a widespread belief and it is not supported. There is no good evidence that forcing fluids during acute colic speeds passage or reduces pain, and adding urine to an already obstructed system can worsen the pain. High fluid intake is the single best way to <em>prevent<\/em> stones forming, which is where the advice comes from, but it is not a treatment for the attack. Drink normally to thirst, and if vomiting prevents that, you need intravenous fluids rather than more effort at home.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Which painkiller works best for ureteric colic?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">An anti-inflammatory (NSAID) is more effective than paracetamol for this pain, because it lowers pressure in the obstructed system as well as relieving pain. It is not suitable for everyone: avoid it with kidney impairment, ulcer or previous gastrointestinal bleeding, NSAID-sensitive asthma, heart failure, or in pregnancy, and take care alongside blood thinners or ACE-inhibitor and diuretic blood pressure medication, particularly when dehydrated. Paracetamol is the fallback. Pain not controlled by simple painkillers means being seen rather than taking more.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why is a CT scan used rather than ultrasound?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Non-contrast CT shows where the stone is, how large it is, how obstructed the kidney is, and how dense the stone is \u2014 the four things that decide treatment, including whether shockwave treatment is likely to work. Low-dose protocols are used where possible. In pregnancy and in children, ultrasound is used first to avoid radiation, and ultrasound is a reasonable initial look in a known stone-former, but it is not accurate enough to plan a procedure around.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Should I keep the stone if it passes?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes.
