Can I Have Kidney Stone Surgery During My Period?

Yes. Having your period is not a medical reason to postpone kidney stone surgery. RIRS, URSL, ESWL and PCNL can all be performed safely during menstruation, and the surgical team handles it routinely.

Many women still ask about it, often quietly, and some cancel a planned surgery date because their period arrived. That delay is usually unnecessary. In a few situations it can be harmful.

This article explains why your period does not affect the surgery, the small practical points that do matter, and when you can choose to reschedule for comfort.

Why Your Period Does Not Affect the Surgery

It does not increase surgical bleeding. Normal menstruation does not change your blood's ability to clot in any meaningful way. The bleeding risk during stone surgery is the same on day two of your period as on any other day.

It does not change the anaesthesia. General and spinal anaesthesia are given in exactly the same way. See do patients need anaesthesia during RIRS.

It does not affect the urinary tract being operated on. Menstrual blood comes from the uterus through the vagina. Stone surgery works through a completely separate passage, the urethra, bladder, ureter and kidney. The two do not interfere with each other.

It does not raise the risk of infection. Standard sterile preparation is the same whether or not you are menstruating.

So from the surgeon's point of view, your period is a practical matter of hygiene and communication, not a medical risk.

The Practical Points That Do Matter

Tell the Team

Let the nurse or doctor know when you are admitted. It is routine for them and they will simply plan for it. Women who stay silent out of embarrassment often worry far more than they need to.

Tampons and Menstrual Cups

You will usually be asked to remove a tampon or menstrual cup before going to theatre. During stone surgery you lie on your back with your legs supported, and the team needs clear access to the urethral opening. A tampon forgotten for many hours also carries its own risk of infection. A sanitary pad is the normal alternative and is perfectly acceptable during the procedure. Staff will help manage this while you are asleep.

Your Urine Test

Before surgery you will almost always have a urine test, and often a urine culture to check for infection. Menstrual blood can contaminate the sample and make it look as though there is blood or infection in the urine when there is not.

Tell the staff you are on your period before giving the sample. They may ask for a careful clean-catch midstream sample, or collect urine through a small catheter, so the result is accurate. A misleading urine report can delay surgery or lead to unnecessary antibiotics.

Pregnancy Test Is Still Needed

Women of reproductive age are routinely given a pregnancy test before stone surgery, even if they are currently bleeding. This matters because some procedures use X-ray imaging, and shock wave treatment is not performed during pregnancy.

Light bleeding in early pregnancy can sometimes be mistaken for a period, so the test is done regardless. If your period is late, lighter than usual or unusual in any way, mention it. See kidney stones in pregnancy.

Heavy Periods and Low Haemoglobin

If your periods are very heavy, you may have a low haemoglobin level, which is checked in routine pre-operative blood tests. Mention heavy periods, and any medication you take for them, such as tranexamic acid or hormonal tablets, so the team has the full picture.

Birth Control Pills

Tell the team if you take combined hormonal contraceptive pills. For short day-care procedures like RIRS they are usually continued. For longer or more extensive surgery, your surgeon may give specific advice. Do not stop them on your own.

After Surgery: Telling Period Blood From Urine Bleeding

This is the one area where your period genuinely causes confusion.

After RIRS or URSL, blood in the urine is normal for a few days, and longer if a DJ stent is in place. If you are also menstruating, it becomes hard to judge how much of the blood is coming from the urinary tract.

A simple approach helps. Wear a pad, and when you need to check, pass urine into a clean disposable cup or container rather than looking into the toilet. Urine that is pink or light red and clears with fluids is expected. Thick clots in the urine, or urine that stays dark and does not clear, needs assessment. See blood in urine, what it means.

Some women also find period cramps and stent discomfort overlap, since both are felt in the lower abdomen and pelvis. Simple painkillers prescribed after surgery usually help both. See DJ stent explained.

It is also common for a period to arrive a few days early or late after surgery. Physical stress, anaesthesia and disturbed sleep can shift the cycle slightly. It settles by the next cycle and is not a sign of a problem.

Stent Removal During Your Period

If your DJ stent removal falls during your period, the short procedure can still go ahead in most cases. The same points apply: tell the team, and expect a pad rather than a tampon. Some women prefer to move the appointment by a few days for comfort, which is reasonable as long as the stent does not stay in much beyond the planned date. A forgotten or long-delayed stent is a far greater risk than any period. See is DJ stent removal painful.

When You Can Choose to Reschedule

For a planned procedure on a stone that is not causing a blockage or infection, it is entirely reasonable to move your date by a few days if you would feel more comfortable. Some women prefer this for personal, practical or cultural reasons, and that is a valid choice. Discuss it with your surgeon, ideally when the date is being fixed, so the schedule can be planned around your cycle from the start.

When You Should Never Wait

Do not postpone surgery because of your period if you have:

• Fever or chills with flank pain. A blocked, infected kidney is an emergency and can deteriorate within hours.
• A stone blocking urine flow, especially with swelling of the kidney on the scan
• Severe pain not controlled by medication
• Very little or no urine
• Only one working kidney

In these situations, delaying treatment for a few days can cause lasting kidney damage or a serious infection. The team will manage your period without difficulty. See how to know when a kidney stone is serious.

Getting Ready for Surgery

For the wider preparation checklist, see preparing for kidney stone surgery and the recovery after kidney stone surgery. For stone problems specific to women, see kidney stone symptoms in women and what causes kidney stones in women.

The procedure itself, whether RIRS, URSL, ESWL or Mini PCNL, is chosen based on the stone, not on your cycle. Our kidney stone checker gives a quick idea of what your stone size and location usually need, and our kidney stone treatment page explains the options.

If you would like to plan your surgery date around your cycle, or have questions you would rather ask privately, book a consultation with Dr. Deepanshu Gupta.

Frequently Asked Questions

Can kidney stone surgery be done during periods?

Yes. Menstruation is not a medical reason to postpone RIRS, URSL, ESWL or PCNL. The bleeding risk, anaesthesia and outcome of surgery are the same.

Does having my period increase bleeding during surgery?

No. Normal menstruation does not meaningfully affect blood clotting, so it does not increase surgical bleeding.

Can I wear a tampon or menstrual cup during surgery?

You will usually be asked to remove it before theatre and use a sanitary pad instead. The team needs clear access to the urethra, and a tampon left in for many hours carries an infection risk.

Will my period affect my urine test before surgery?

It can. Menstrual blood may contaminate the sample and give a misleading result. Tell the staff, and they may collect a careful clean-catch sample or use a small catheter.

Do I still need a pregnancy test if I am on my period?

Yes. Women of reproductive age are routinely tested before stone surgery, because some bleeding in early pregnancy can resemble a period and some procedures involve X-ray or shock waves.

How do I tell period blood from blood in my urine after surgery?

Wear a pad and pass urine into a clean container when you want to check. Pink urine that clears with fluids is expected after surgery. Clots or persistently dark urine need assessment.

Can surgery make my period come early or late?

It can shift your cycle by a few days because of physical stress, anaesthesia and disturbed sleep. This usually settles by the next cycle.

Can I reschedule my surgery because of my period?

For a planned procedure on a stone that is not blocking urine or causing infection, yes, moving it by a few days is reasonable. If there is fever, blockage, severe pain or very little urine, surgery should not wait.
