What is a Cystometry/Cystometrogram (CMG)? Cystometry, or cystometrogram, with a pressure flow study is part of urodynamic testing (or UDS). These tests measure how well the bladder functions. They help diagnose problems related to urine control. These can be incontinence, difficulty emptying the bladder, overactive bladder, obstructions or frequent infections. Cystometry is used to measure how much urine the bladder can hold.
Tums - Expiration Date. I got a large package of Tums at a discount store for a really good price, but didn't notice the expiration date until later. They are marked June 2004 - I'd throw them out, but I remember my former boss who used to work at a pharmacy told me that asprin usually lasts much longer than its expiration date.
Visa Expiration Date is just the last date u can use the Visa to travel into the US. If your Visa expires on Dec 31 u can still travel on Dec 31 provided u will arrive in the US on the 31. The length of your stay is not on the Visa it is on the I-94. People do have expired Visa but their I-94 is still valid. A US Visa is just for u to travel to a US Point of Entry and apply for entry. The expiration date of the I-94 is the main thing.
