Question: I just got the results of my urinalysis. The "uwbc" count was greater than 100 and the "urbc" count was 50-100. The doctor put me on omnicef for a sinus infection but never mentioned a UTI. What does urbc and uwbc mean and should I be concerned?

Thanks for your query. I understand your concerns. Following is my reply:

1) UWBC means Urine White Blood Cells. White blood cells in urine are indicative of UTI. Especially if they are more than 100 per high power field (hpf). Hence, it needs to be treated with antibiotics. Omnicef is an antibiotic, which also might help in treating this. Hence, continue the tablets.

2) URBC means Urine Red Blood Cells. RBC is nothing but suggests there is some mild bleeding in your urinary tract. It could be due to some mild trauma, infection or calculi (stone) in urinary system. However, as long as you have no problem, don’t worry about it.

3) I suggest you complete the course of omnicef your doctor has given you. Then repeat the urine analysis after 15 days from another standard laboratory. If still WBC exists, you get urine culture and sensitivity done which suggests sensitivity to best antibiotic.

4) If RBC again appears in urine after 15 days, please get an ultrasound to rule out calculi, which are a common cause.

I hope I answered your query.

I think I may have a bladder infection but the only pain I'm feeling is in my urethra. It is constant pain, it is the worst in the morning and during and after I urinate. I do not seem to have any of the other symptoms I have read about, No stomach or back pain, No fever. My urine is cloudy but no traces of blood. I am wondering if there is anything else, other than a bladder infection that has similar symptoms. This started after having sex, first it hurt during sex, then during urination and now it's constant, all within the last week, and has gotten severely worse to the point where I am in tears multiple times a day.

About 5 weeks ago I developed cystitis which I tried to get rid of myself by drinking plenty of fluids and cranberry juice. I couldn't get rid of it and was presribed trimethroprim for 3 days, this did nothing so I went to GP again on 4 day as I was vomiting and was unable to keep anything down by then. The GP prescribed Ciprofloxacin and painkillers but I couldn't keep these down either. By the following day my skin was a yellow colour and I was taken into hospital for 5 days and given Augumentum through a drip and the infection was the E-coli bacteria. I went home with 2 more days of antibiotics to take orally. I was still experiencing pain in the flank about 4 days after taking my last antibiotic so I called the Dr and blood test confirmed I still had the infection. I was given Augmentum for 7 days but 5 days after taking the last one I was still feeling bad. I was given Nitrofurdantoin on Friday to take 4 times a day but the pain seems to be getting worse. I am also anaemic and have been taking ferrous fulmurate since January. If I go back to the GP should I be asking to see a specialist?

I am a 46 year old woman with no medical problems other than one or two UTI's every few years. I am 5'8" and weigh 160 pounds. I have been to my doctor and she diagnosed me with possible interstitial cystitis. I was referred to a urologist and set up with an appointment that is two weeks away. I wasn't given anything for a pain or the sympotoms, but I was given an antibiotic. I started that yesterday. I have adjusted my diet and have even taken an over-the-counter meds for the pain. Is there something else that I can do now? Should I continue to suffer? Is there some immediate help that I can get at the ER?
