24-hour urine collection and stone analysis24 ghante ka peshab collection aur pathri ka tajziya

A 24-hour urine collection measures what your urine contains over a full day, and how much you pass. It helps find out why stones form, and whether changes to your diet or fluids could help prevent them. If you have passed or had removed a stone, the stone itself can be sent for analysis to find out what it is made of. This guide explains how to collect the urine and what the results can tell you.

Yeh test kya hai aur kyun kiya jata hai

Is 24 ghante ke peshab collection mein aap aik poore din ka har qatra peshab aik khaas container mein jama karte hain. Lab hajam (volume) aur un cheezon ko napti hai jo pathri bana sakti hain, jaise calcium, oxalate, citrate aur uric acid.

Is pathri ke tajziye mein, jo pathri nikli ho ya nikali gayi ho, woh lab bheji jati hai. Lab dekhta hai ke woh kis cheez se bani hai, jis se urologist sahi rokthaam ka faisla karta hai.

Aasaan tasveer. Baayen taraf dhakkan wala container jis mein aik din ka peshab hai. Daayen taraf sealed pot mein pathri, tajziye ke liye.

Urologist yeh tests keh sakta hai agar aap ko baar baar pathri bane, agar bachay mein pathri mili ho, ya agar pathri ka tajziya ho chuka ho aur wajah abhi bhi saaf na ho.

Shuru karne se pehle

  • Team se collection ka container aur likhit hidayat shuru karne se pehle le lein.
  • Aisa din chunein jab aap saara peshab jama kar sakein, aur container qareeb rakhein.
  • Apni aam diet aur pani jaari rakhein, jab tak team kuch aur na keh de. Test ke liye naya supplement shuru na karein ya bari tabdeeli na karein.
  • Apne taur par koi dawa band na karein. Team ko apni tamam dawaon ke baare mein batayein.
  • Agar aap beemar hon, bukhar ho, ya peshab ka infection ho, to team ko batayein, kyun ke is se nateeja badal sakta hai.

Peshab kaise jama karein

Pehle din subah, peshab toilet mein kar dein aur woh peshab jama na karein. Waqt note kar lein. Us ke baad aap har peshab container mein jama karein, agle din subah ka pehla peshab bhi, jab tak agle din usi waqt tak ka collection poora na ho.

  • Container ko thandi jagah rakhein, jaise fridge mein, jab tak lab kuch aur na kahe. Khane se door rakhein.
  • Agar container par nishan hon to kul hajam likh lein, aur koi masla ho, jaise koi sample chhoot jana, woh bhi likh lein.
  • Agar koi sample chhoot jaye to lab ko batayein. Dobara collection zaroori ho sakti hai.
  • Container ko haath lagane se pehle aur baad mein haath dhoyein, aur dhakkan band rakhein.

Pathri ke tajziye ke liye, pathri ko saaf aur sukhe container mein rakhein, aur team ke kehne par woh lab le aayein. Pathri ko khud saaf karne ya todne ki koshish na karein.

Collection ke baad

  • Container ko hidayat ke mutabiq lab ya clinic wapas karein, is par apna naam aur tafseel lagi ho.
  • Aap apna mamool ka din shuru kar sakte hain.
  • Nateeje aam tor par thore arse mein tayar hote hain aur aap ke urologist ko bheje jate hain. Nateeje par baat kiye bina diet ya pani mein khud tabdeeli na karein.

Mumkin khatre

Ghar par peshab jama karne mein koi jismani khatra nahi. Asal masla durustagi ka hai: agar collection adhoora ya chhoot jaye to nateeja aap ke aam pattern ko zahir nahi karega. Isi liye team test dobara keh sakti hai.

Pathri ka tajziya mehfooz test hai. Pathri ko khud nikalne ya todne ki koshish na karein.

Aap ke nateeje

Report mein peshab ka kul hajam, aur woh cheezein jo pathri bana sakti hain, un ki miqdar dikhayi jati hai. Agar pathri ka tajziya hua ho to report batati hai ke pathri kis cheez se bani hai.

Aap ka urologist in nateejon ko aap ki history, muaine aur scans ke saath dekh kar faisla karta hai ke diet, pani ya dawaon mein koi tabdeeli madadgar hai ya nahi. Apni diet, supplements ya dawaon ko khud na badlein. Report apne urologist ko dikhayein, jo samjhayega aur agle qadam tay karega.

Fauran madad kab lein

Yeh test fauran wala test nahi. Agar collection ke dauran ya baad mein yeh hon to fauran madad lein:

  • Pait ke ek taraf ya peeth mein shadeed dard, khaas tor par ulti ke saath (dekhein gurdon ke dard ki guide).
  • Bukhar ya kaampna, jalan ya kamar ke dard ke saath (dekhein UTI guide).
  • Peshab bilkul nahi ho raha.
  • Peshab mein bhari khoon ya khoon ke lothray.

Agar shak ho to qareebi emergency department jayein aur test ka khat dikhayein.

Aam sawalaat

Kya mujhe har qatra jama karna hai?

Haan, jahan tak mumkin ho. Nateeja poore din ka saara peshab jama karne par munhasir hai. Agar koi sample chhoot jaye to lab ko batayein, kyun ke dobara test zaroori ho sakta hai.

Kya main aam tor par pani pi sakta hoon?

Haan, jab tak team mukhtalif hidayat na de. Yeh test aap ka aam pattern dikhata hai, is liye test ke liye pani mein tabdeeli madadgar nahi.

Kya roza rakhna zaroori hai?

Nahi. Apna aam khana khayein, jab tak team aur na kahe.

Itni cheezon ka test kyun hota hai?

Mukhtalif pathriyan mukhtalif wajah se bantin hain. Kai cheezon ko napne se urologist asal wajah dhoondh sakta hai, taake sahi rokthaam chuna ja sake.

Kya test dobara karna parta hai?

Kabhi kabhi. Peshab din ba din badalta hai, is liye urologist dobara collection keh sakta hai taake tasveer pakki ho.

Agar pathri nikal gayi ho lekin main ne sambhal kar na rakhi ho to?

Team ko batayein. Woh baaqi tests ka mansooba bana sakti hai, aur agli pathri ka tajziya ho sakta hai.

Kya main pathri roknay ke liye supplements le sakta hoon?

Apne taur par supplements shuru na karein. Kuch cheezein kuch logon mein pathri ka khatra badha sakti hain. Koi bhi cheez shuru karne se pehle urologist se poochhein.

What it is and why it is done

In the 24-hour urine collection, you collect every drop of urine passed over one full day, in a special container. The lab measures the volume and the substances in it that can form stones, such as calcium, oxalate, citrate and uric acid.

In stone analysis, a stone that has passed, or been removed, is sent to the lab. The lab looks at what it is made of, which helps your urologist choose the right prevention.

Your urologist may ask for these tests if you form stones more than once, if a stone has been found in a child, or if a stone has been analysed and the cause is still unclear.

Before you start

  • Ask the team for the collection container and any written instructions before you start.
  • Choose a day when you can collect all your urine, and keep the container close by.
  • Keep your usual diet and fluids, unless your team has given you different advice. Do not start a new supplement or make big changes just for the test.
  • Do not stop any medicine on your own. Tell the team about everything you take.
  • Tell the team if you are unwell, or if you have a fever or a urine infection, as this can change the result.

How to collect the urine

On the first morning, empty your bladder into the toilet and do not keep that urine. Note the time. From then on, collect every sample you pass into the container, including the first urine of the next morning, until the same time the following day.

  • Keep the container in a cool place, such as a fridge, unless the lab tells you otherwise. Keep it away from food.
  • Write down the total volume, if the container has measurements, and any problems you had, such as a missed sample.
  • If you miss a sample, tell the lab. A repeat collection may be needed.
  • Wash your hands before and after handling the container, and keep the lid on.

For a stone analysis, keep the stone in a clean, dry container and bring it to your team as they have asked. Please do not try to clean or break the stone yourself.

After the collection

  • Return the container to the lab or clinic as instructed, with your name and details on it.
  • You can carry on with your usual day straight away.
  • Results are sent to your urologist, usually within a short time. Please do not try to change your diet or fluids on your own before you have discussed the results.

Possible risks

Collecting urine at home has no physical risk. The main issue is accuracy: a missed or incomplete collection can give a result that does not reflect your usual pattern. This is why the team may ask you to repeat the test.

Stone analysis is a safe test. Please do not attempt to remove or break a stone yourself.

Your results

The report shows the total urine volume, and the levels of substances that can form stones. The stone report, if one was done, describes what the stone is made of.

Your urologist uses these results with your history, examination and scans to decide whether any changes to diet, fluids or medicines are useful. Please do not change your diet, supplements or medicines on your own. Take the report to your urologist, who will explain it and agree the next steps with you.

When to seek urgent help

This test is not an emergency test. Please seek urgent help if any of these happen during or after the collection:

If you are in any doubt, go to the nearest emergency department and show them your test letter.

Common questions

Do I have to collect every drop?

Yes, as far as you can. The result depends on collecting all the urine for the day. If you miss a sample, tell the lab, because a repeat may be needed.

Can I drink as normal?

Yes, unless your team gives you different advice. The test shows your usual pattern, so changing your fluids just for the test is not helpful.

Do I need to fast?

No. Keep your usual meals, unless your team tells you otherwise.

Why does the lab test for so many substances?

Different stones form for different reasons. Measuring several substances helps your urologist find the likely cause, so the right prevention can be chosen.

Do I need to repeat the test?

Sometimes. Urine changes from day to day, so your urologist may ask for a second collection to confirm the picture.

What if I have passed a stone but not kept it?

Tell your team. They can still plan the other tests, and the stone analysis can be done on a later stone.

Can I take supplements to help prevent stones?

Please do not start supplements on your own. Some can make stones more likely in certain people. Ask your urologist before you start anything.
