If no goals are associated with a plaything, it is a toy. (Crawford notes that by his definition, (a) a toy can become a game element if the player makes up rules, and (b) The Sims and SimCity are toys, not games.) If it has goals, a plaything is a challenge.
Topic Overview. The post-void residual (PVR) urine test measures the amount of urine left in the bladder after urination. The test is used to help evaluate: Incontinence (accidental release of urine) in women and men. Urination problems. An enlarged prostate (benign prostatic hyperplasia, or BPH).
Conclusions. TRV/TVI RVOT is a reliable method to identify patients with elevated PVR. In patients with TRV/TVI RVOT echo2 derived from TRV 2 /TVI RVOT provides an improved noninvasive estimate of PVR compared with PVR echo.
