I have urinary retention for two weeks now, tomorrow I may have full diagnoses, weather its due to infection or blockage, i had it for 2 weeks now, when i want to urinate i stand for a while then it comes and not always fluently, i have to drink tons of water to urinate more than once, i just want to know what test to do to know if the kidney is full of fluids?? and how to evaluate its condition other than the creatinine level, mine is 1.2 now, I'm scared, i have the retention and pain in my left side, i did a ct scan but without dye, as I'm afriad something is wrong with my kidneys so I didn't want to push them more by injecting dye into my system, also the emergency doc i went to said this is due to infection and he prescribed cipro 250, is it safe to take it? all my blood work is within normal range and my sonar showed no stones, the CT ( without dye only drank lots of water) showed 2mm opaque stone ad middle calyx of left kidney, mild fullness of left pelvicalyceal system and ectatic left ureter and no stones in the bladder, should i do it with dye in order to be more visible? and since I have the retention I'm afraid the dye might damage my kidneys, please help anyone ;(
