If the urethra is less than one and a half centimeters, we'd advocate for a urogenital separation. And the reason for that is if you were to do a TUM on a patient with a one centimeter urethra, and although these patients aren't common, they do exist, then you will have their bladder neck sewn right near the perineum. And that could render the patient incontinent.
I think if you look at these pictures we have, you can see when we're looking at a lateral view, how the common channel actually takes a very significant turn as it gets behind the pubis.

clinicalCongenital perineal groove has a normal anal opening and is an exposed wet sulcus of non-keratinized mucous membrane that usually epithelializes on its own by age two↗
▶Ep 98 · 9:11
clinicalThree qualities to assess in anal location are: anal size, location (whether surrounded by sphincter muscle complex), and the peroneal body that separates it from the introitus or urinary structures↗

clinicalUrogenital sinus plus a normal anus is an endocrine problem, but no anus and a urogenital sinus is a cloaca↗

▶Ep 98 · 15:03
clinicalThe biggest question with female anorectal malformation exam is how many perineal orifices are there↗
▶Ep 98 · 15:03
clinicalIf there are three orifices, the question is whether it is a perineal fistula or a vestibular fistula↗
▶Ep 98 · 15:03
clinicalIf there are two orifices, it is important to know if there is a fistula at all, vaginal atresia, or a rectal vaginal fistula↗
guidelineA cloaca or anorectal malformation is associated with VACTERL and needs to be worked up as such.↗
▶Ep 102 · 3:10
guidelineVACTERL association requires three or more anomalies: vertebral, imperforate anus, cardiovascular, tracheoesophageal fistula, esophageal atresia, renal/radial, and limb defects.↗
▶Ep 102 · 8:45
guidelineInitial workup should consist of an NG tube and chest X-ray, cardiac echo, and pelvic and renal ultrasound to assess for TEF, cardiac anomalies, hydrocolpos, and hydronephrosis.↗

clinicalCystoscopy significantly undermeasures anatomical structures compared to 3D reconstruction because the straight scope cannot accurately measure the turn behind the pubis↗
▶Ep 237 · 6:45
quoteWhat we found when we studied it was that the cystoscopy significantly undermeasures the structures when you scope and you compare the same patient's 3D reconstruction to their scope.↗

quoteYour straight scope can't measure that turn.↗
▶Ep 237 · 11:57
clinicalIf urethral length is less than 1.5 cm, urogenital separation is advocated because performing TUM would result in the bladder neck being sewn near the perineum, potentially rendering the patient incontinent↗
