Hi doctor,

Today I had a cystoscopy as I have blood in my urine. Nothing was found, so I have been referred for an ultrasound on my kidneys. I have had cancer twice and worry a lot. I was told to remove my trousers and underwear but keep my top and innerwear on. I realized after the scan that my innerwear straps were hanging down where the cystoscopy went in. Could this hinder the scan results? And is it ok to have a mobile phone and fitness watch on? Would that interfere with the camera scope? Kindly give your opinion.



Welcome to icliniq.com.

Gross hematuria should be investigated thoroughly. Investigations include urine analysis and culture urine for cytology with three samples, one sample each day, flexible cystoscopy, and CT-IVU (computed tomography with intravenous urogram). In some centers, by the time before the CT scan appointment, they get an ultrasound. Please note the ultrasound results will not be affected by the innerwear or any electronic device, whether it is a phone or digital watch, and it will not as well interfere with the scope result.

If you have any more queries, please do not hesitate to ask.

Hi doctor,

Thank you.

I have had blood in my urine for years, but it is only small and cannot be seen by the naked eye. Would my innerwear strap, mobile, or watch affect the cystoscopy results? Kindly give your opinion.



Welcome back to icliniq.com.

As I mentioned earlier, innerwear strap, mobile, or watch will not affect the cystoscopy results. Cystoscopy is a direct vision, and it is done by a urologist. And interpretation is made by the same doctor who did the scope. And the result of ultrasound is also not affected by the innerwear strap, mobile, or watch. I hope this was helpful.
