Which condition is characterized by the accumulation of urine in the bladder due to obstruction?

The accumulation of urine in the bladder due to obstruction is accurately described as urinary retention. This condition occurs when the bladder cannot empty completely, leading to an increase in its volume. It can result from various factors, such as physical blockage (e.g., enlarged prostate, bladder stones) or functional issues related to the bladder's muscle control.

In urinary retention, the patient may experience symptoms such as a frequent urge to urinate, discomfort, or an inability to urinate despite feeling a strong need to do so. Chronic urinary retention can lead to complications like urinary tract infections, bladder damage, or kidney problems.

Other conditions listed, such as incontinence, neurogenic bladder, and overflow incontinence, do not directly align with the specific characteristic of urine accumulation due to obstruction. Incontinence refers generally to involuntary leakage of urine, neurogenic bladder involves issues with nerve signals affecting bladder function, and overflow incontinence occurs when urine overfills the bladder and leaks out, often associated with urinary retention but doesn't directly define the obstruction aspect.
