Urethral crest
Anatomical feature of the urinary system
The urethral crest is an anatomical feature present in the urinary system of both males and females.
In males, the urethral crest is known as the crista urethralis masculinae, or the crista phallica, and is a longitudinal fold on the posterior wall of the urethra extending from the uvula of the bladder through the prostatic urethra.
It is from 15 to 17 mm. in length, and about 3 mm. in height, and contains muscular and erectile tissue.
When distended, it may serve to prevent the passage of the semen backward into the bladder.
In females, it is known as the crista urethralis femininae, and is a conspicuous longitudinal fold of mucosa on the posterior wall of the urethra.

Why this record matters
“Urethral crest” is worth following because a concise public description often conceals a longer documentary argument. Here, Urethral, crest and Anatomical provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Oct 5, 2025. The linked authority identifier is Q3697092. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2016.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
