Position of the Bladder

so in this video I'm going to talk about

the position of the urinary bladder

inside the body so the bladder is a

pelvic organ it's retroperitoneal by

position and it is normally in in an

empty state it is present behind the

symphysis pubis so in front of you is a

Hemi section through the male pelvis

showing us the bladder and other

structures present in the pelvic cavity

and here you can see this is the

symphysis pubis and this is the lower

part of the anterior abdominal wall with

all the skin subcutaneous fat fascia and

then muscles and then the plutonium okay

all right here is the apex and this is

the ligament I was talking about

originating from the apex or attached on

the apex and reaches up to the umbilicus

this is the median umbilical ligament or

Eureka's or Eureka's okay so in normal

circumstances in an adult the urinary

bladder partially full or empty is mine

inside the pelvic cavity or true pelvis

while in an infant this bladder whether

it's empty or is filled it's lying

inside the abdominal cavity because in

the infant the pelvic region is still

growing and it's a small narrow space so

the urinary bladder is an abdominal

organ in infants and that explains why

the because due to the pressure and

negative pressure of the abdominal

cavity when a Venna when an infant is

peeing he has has a very fast stream

away like you know that rushes out

because of the pressure from the other

internal organs while in adults the the

bladder descends down and settles in to

its normal and advocate position that is

in the true pelvis or the lesser pelvis

okay now what happens I told you that

the the bladder has a capacity of up to

500 milliliters of urine in one point of

time it can hold okay as the bladder is

filling I want you to imagine I always

give this example you imagine the

bladder like a Sun rising over the

horizon okay so it's raw it is rising

slowly so the fundus of the bladder as

it is getting full you know the cavity

is getting full it's getting distended

urine is constantly collecting so it

just you know it rises up and and I have

mentioned that the superior surface or

the fundus of the bladder is covered by

the peritoneum from the top okay the

peritoneum is not wrapped around the

bladder it's just covering the soupy air

surface so as the the bladder is getting

full it is rising like a Sun on the

horizon and it's entering it's crossing

the symphysis pubis and just peeps out

of the pelvic cavity into the abdominal

cavity what is happening at is it it is

getting full it's getting distended and

distended it's it's you know peeling off

the parietal peritoneum or the abdominal

peritoneum and it's you know occupying

this area behind the peritoneum or

outside the peritoneal cavity okay it

always stays outside the Britannian we

have to keep in mind sometimes what

happens in small children and also in

adults there is extraordinary retention

of urine like in cases of BPH like

benign prostatic hyperplasia or any any

situation that leads to obstruction

urethral obstruction of some sort so

there would be chronic retention of

urine and minute reaches like it's

getting more and more it spilling of the

the petunia layer from the anti

abdominal wall and it's becoming an

abdominal organ so they perform

assistance taught me like they they

insert a needle to relieve the pressure

so how do they do that they cross

through the skin the the campers and

superficial fasciae both elements the

the Scarpas and campers and then the

Linea Alba which is the you know the

bloodless line the way a vascular line

present in the mid of the abdominal wall

that is like below the umbilicus and

then the you know the fasciae

transversal ascends and they reach to

this level which is the bladder wall so

that that needle has entered the swollen

or you know distended bladder wall after

crossing all these structures and the

the urine can be aspirated out to

relieve the pressure and and prevent the

bladder from rupturing okay so it's

important to understand by the way a

full bladder can up can reach up to the

level of umbilicus although it's a it's

a pubic or a pelvic organ it's lying

behind the pimple symphysis pubis but it

when it gets starts getting distended it

can't stand up to so much that it

reaches the umbilicus okay but there are

chances of rupture in case or if

somebody has blown blown or blown

someone's abdomen in the region of the

standard bladder so then tear

bladder wall will rupture and the urine

can get collected here in the

subcutaneous tissue which is fashio and

that you know Atkin can can call
