22days post ureteroscopic kidney stone removal&stent placement still passing stones not on CT ?  Scans show nonobstructing  stones  how  can  this be?

Possible: It is good to pass the stones- obstructing or non- obstructing is only a matter of size of the stone and diameter of the ureter ( which is the tube from kidney to the bladder) small size stones may not be seen on ct. Check with your doctor- if kidney stones is a recurrent issue, may benefit if you see a nephrologist who can do some special tests and advise preventive measures. ...Read more

Most of the time it is stained and looked at through a microscope to arrive at a diagnosis. Special processes are done for some tissues or problems. The purpose is to tell what the problem is (diagnosis). ...Read more

Can a long dormant, asymptomatic kidney stone be precipitated into renal colic and eventual passage by a digital prostate exam?

Can a long dormant, asymptomatic kidney stone be precipitated into renal colic and eventual passage by a digital prostate exam?

Complex question: I do not believe that a digital rectal exam can help move a stone out. If you have a dormant kidney stone, it depends on where it is located in the urinary passage. Colics are produced only when the stone is moving down the ureter. Once it has passed down the ureter then there is lesser odds of colic although it can get stuck in the urethra and cause painful urination. Let us know where its locate. ...Read more

Will urethral stent removal be painful?

Will urethral stent removal be painful?

Very briefly.: An indwelling ureteral stent is removed in one of two ways. A quick pull on a little string to pull it out of the urethra, or by using a flexible scope to enter the bladder and pulling out the stent with forceps. Both can cause bladder discomfort and some flank pain as it is quickly removed. Some residual pain can linger for a day or two. Pain can be variable with many feeling no pain. ...Read more

For the left urethra at the bladder with blockage from kidney stone or scare tissue from past ureteroscopies have a stent or resection as a choise ?

For the left urethra at the bladder with blockage from kidney stone or scare tissue from past ureteroscopies have  a stent or resection as a choise ?

Here are some ...: How to manage the blockage at the ending part of left ureter by the scar after ureteroscopic stone procedures relies on the degree and length of the scar and the balance between medical necessity and professional possibility. At that level, options of care may range from doing nothing or incision + a period of stent or permanent stent with regular change 2-3 times yearly or surgical correction... ...Read more

How do they remove a stent placed after kidney stone removal surgery?

How do they remove a stent placed after kidney stone removal surgery?

Two ways: If the stent is left with a long "string" if intended to be short term, this can be grasped and pulled out easily. If there is no visible string, an office procedure to retrieve it with a flexible fiberoptic scope (cystoscopy) is a rapid and relatively painless method to remove the stent. ...Read more

Recurrent stones: Most likely due to calcium oxalate stones, a specific salt that causes these stones. It is possible that you have hyperoxaluria, a high amount of this "oxalate" in your blood. If you have this, it should be tested for in your blood so that you can know. ...Read more

What are symptoms of damage to urethra, bladder or ureter after urethral stent removal and is there a way to determine damage without imaging?

Stent removal: If you are referring to a ureteral stent removal there are very few side effects associated with their removal. The length of time they were indwelling could have an effect on whether they are encrusted with stone or not. Imaging with I.V. Dye and cystoscopy would be appropriate if symptoms remained after 3 to 4 weeks from removal. ...Read more

Can anything be done at home to speed passage of small, painful kidney stones? ~12, largest 4mm, dx by U/S, none visible on CT, one sent to lab.

Drink water: Drink enough water so that your urine is colorless. Flow of urine may facilitate the passage of stones. You need to keep up high intake of water to prevent more stones from forming. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

Lithotrypsy 10/15/14 kidney & opposite ureter. Still have Hydronephrosis both  kidneys. Can cause be healing from procedure. CT Scan scheduled. Thanks?

Congratulation....: Congratulate for having successfully gone through procedures as reported 4 weeks ago. Lesser dedree of hydronephrosis may be still present if it was prominent resulting from long-term obstruction before procedures. So, ask Doc to elaborate the sequence of events in the imaging studies before & after procedures. At times, a degree of hydronephrosis may persist forever after a reasonable resolution. ...Read more

I am 24 year old suffering from kidney stone which obstructed in ureter confirmed by ultrasound exam is of 7-8 mm. Can it be pass without surgery?

I am 24 year old suffering from kidney stone which obstructed in ureter  confirmed by ultrasound exam is of 7-8 mm. Can it be pass without surgery?

Possibly: Stone size is the major determinant of the likelihood of spontaneous stone passage. The location of the stone is also important. With stones larger than 4 mm in diameter, there is a progressive decrease in the spontaneous passage rate, which is unlikely with stones > 10 mm. Proximal ureteral stones are also less likely to pass on their own. ...Read more

Rare, but depend...: Urethral stricture (scar) may rarely occur reflecting the types-rigid or flexible-of scope used, the times of scoping, personal anatomical variation, & personal healing ability. For one at 27 without prior urethritis & instrumentation, the cause for recurrent voiding usually results from poor relaxation in prostate urethra. More?
