What are my chances of successfully passing my stone?- A KidneyStoners.org Infographic

We frequently receive questions from patients trying to pass a stone who want to know whether they will be able to pass it successfully.  There are three main factors that your doctor uses to predict your chances of successful stone passage. These include stone size, stone location, and what length of time you have been trying to pass the stone. We go over each factor in the infographic below.

    On a Friday night I went to the emergency room at the hospital. I was in a lot of pain. CT Scan showed I was passing a kidney stone and that their was a large stone still in my left kidney. Thay gave me pain pills and sent me home. I was told that if the pain got worse or if I started to throw up and feel worse to come back to the ER. I did fine on Saturday but on Sunday morning I felt achie. My pain pills didn’t seam to help. That night I felt chilled to the point that I had a hard time getting warmed. I got to chattering so bad I had to take a hot bath to get warm. When I woke in the morning on Monday I felt nice and cuddly warm under my covers but when I got up to use the restroom I became really chilled. My restroom has a good base board heater and I cranked it up all the way. I was feeling like I was drunk, my head was swimming. It took me two hours to get ready for the day. The same thing happened on Tuesday. I called my doctor, I was told to go to the ER. On the way to the hospital I noticed a cold soar starting on my lip. They checked my temp. It was ok. They had me take off my shoes and shirt and bra. I imeadiatly went into cold chills. They checked my temp again and it was 103. CT Scan showed that a stone had blocked my kidney. My blood pressure dropped real low and they had to put the IV in my neck. They took me into surgery and placed a stint from the kidney to the bladdar then set in a cathater. The stone blocked all flow from the kidney. In return, infection set in. I was so sick I was in ICU two days and another day and a half in a room. I’m set for surgery in two weeks. I’m taking antibotics and drinking a lot of water. This is a down side to waiting. I’ve been so sick I just want it to be over with.

    I have an “unobstructed” 6mm stone in my right kidney. In December I had a CT scan that showed it was 4mm. My doctors think it’s the same stone that’s increased in size. I’ve had blood in my urine (oftentimes visible to the naked some, sometimes very much).

    I would like to try to pass it but am concerned at this point that if I do, it can get blocked and cause more problems. And why would it just sit in my kidney without trying to pass?

      Dear Brenda,

      Please don’t worry too much. About three weeks ago, I did an advanced yoga position that dislodged a 4mm kidney stone. It left my kidney and entered my ureter on an early Saturday morning. I went to the urgent care on the same day. There was some ‘pressure’ but not a great deal of pain. Two days later I had a CT that revealed it as a 4mm stone. They gave me some Flomax pills to relax the ureter and bladder muscles. They also gave me a funnel to urinate through – so that the stone could be caught and examined. Well, I took the Flomax pill on 11 pm and when I woke up at around 7 am, I urinated through the strainer and I heard a “click”…. it was the stone. I did notice that the urine was a dark color while I was urinating.

      Well, the stone passed and I didn’t feel a thing!

    After having pain and visible blood loss on and off for about 6 months (and nothing being spotted on ultrsound or IVU) I had a 6mm stone identified by CT scan at the outlet to my left Kidney. My consultant advised that I take one 400mcg Tamsulosin capsule daily. The drug widens the tubes from the Kidney and bladder (they’re meant to treat the symptoms of an enlarged prostate). They caused a few mild side effects but I was amazed that after about 4 weeks, largely pain free, I suddenly passed the stone; more uncomfortable than painful (although I did load up on pain killers when I thought it was on its way!) and no blood. I’d had a smaller stone (about 4.5mm and very jagged) about 14 years ago that had to be removed so I was very pleased with the outcome this time round.

  5. Leona says:

    If a stone left in the ureter and does not posess any problems such as blood in urine, pain in side, that means its not moving which can lead to serius problems. It can be stuck in which if it is it will continue to grow and cause obstruction of the kidney or will rupture his ureter. He needs immediate doctors attention.

    How did this turn out for your husband? I have a 3 mm stone still in my kidney and it causes some stabbing pain here and there. The urologist told me to wait another 3 weeks and if it has not come out then we’ll pursue more aggressive treatment.
