How Do I Increase my Bladder Capacity?

Bladder: A muscular cystic organ that stores urine. Its shape, size, location, and wall thickness vary with the degree of urine filling. The average bladder volume of an adult is 350-500 ml. When it exceeds 500 ml, pain occurs due to excessive tension of the bladder wall. The maximum capacity of the bladder is 800 ml. The volume of the bladder in newborns is about one-tenth that of adults. The capacity of women is smaller than that of men. The elderly have increased capacity due to low tension of the bladder muscles.

Bladder Adult Volume Bladder Morphology

The empty bladder has a triangular vertebral body shape, divided into four parts: tip, body, sole and neck. The tip of the bladder is facing forward and upward, so there is a fold between the anterior wall of the abdomen and the umbilicus as the umbilical median ligament. The bladder body is between the tip of the bladder and the bottom of the bladder. The lowest part of the bladder is the bladder neck, which is adjacent to the anterior fissure of the male and the pelvic diaphragm of the female.

Anatomy of bladder in adult volume

The inner surface of the bladder is covered with mucous membranes. When the bladder wall contracts, the mucous membranes gather into folds called bladder loops. On the inside of the bottom of the bladder, there is a triangular area between the left and right ureteral openings and the inner urethral opening. Here the bladder mucosa is tightly connected to the muscular layer and lacks submucosal tissue. It remains smooth regardless of whether the bladder expands or contracts. Called the bladder triangle. The triangle of the bladder is a common site for tumors, tuberculosis, and inflammation. Special attention should be paid to cystoscopy. The fold between the two ureteral orifices is called the ureteral diaphragm. A pale band seen under cystoscopy is a sign of clinically looking for a ureteral orifice. In the triangle of the bladder behind the male urethral orifice, a longitudinal ridge-like bulge formed by the middle lobe of the prostate is called a bladder ptosis.

Bladder adult volume bladder urine storage abnormal

24 hours of urine output is a measure of whether the bladder storage function is normal. Among them, abnormal urine output refers to a normal person's 24h urine output of about 1500 to 2000ml, and the ratio of daily urine output to nocturnal urine output is 2: 1. When the 24h urine output exceeds 2500ml, it is said to be polyuria, less than 400ml or less than 17ml per hour. Oliguria, less than 50ml is said to be anuria.
Diabetes insipidus, diabetes, potassium deficiency, hypercalcemia, early stage of chronic renal failure, polyuria of acute renal failure, non-oliguric acute renal failure, solute polyuria, acute renal failure, severe dehydration, major bleeding , Large area burns, shock, left heart failure, severe arrhythmia, pericardial tamponade and constrictive pericarditis, hepatorenal syndrome, systemic lupus erythematosus, nodular polyarteritis, infective endocarditis, skin muscle Inflammation, chronic renal failure, renal atrophy, drug allergy, heavy metal salt poisoning, disseminated intravascular coagulation (DIC), pregnancy-induced hypertension syndrome, large-scale burns, stones, tumors, prostate hypertrophy, prostate cancer, diabetic neurogenicity The bladder and so on can cause abnormal storage of bladder urine volume.
