Damage to the kidneyKidneys: lie deeply on

the posterior abdominal wall not easily damaged

Fractures of the lower ribs, penetrating wounds in the lumbar region produce kidney damage

Vaskularisasi dan Inervasi

Arterial supply: a. vesicalis inferior, a. profunda penis, a. urethralis

MICTURITIONPressure within the bladder rise afferent

impulses n. splanchnicus pelvicus S2-4 parasympathetic motor: contraction of m.

detrussor, relaxation of m. sphincter vesicaeSomatic fibre relaxation of m. sphincter

urethraRelaxation of the pelvic floor musclesFull contraction of the detrussor assisted by the

muscle of the anterior wall and diaphragmaThe ability to stop the flow of urine

voluntary in midstream:Contraction of the intrinsic striated sphincterContraction of the pelvic floor

Obstruction to urine flow in the male

After the age of 45-50 years the prostate gland very frequently enlarges

Consequence:The tissue pressure on the walls of the prostatic urethra rises the detrussor muscle has to raise pressure to force urine out detrussor muscle hypertrophies:Fail to empty the bladder completelyThe urine stream has less force

Residual urine after micturition:

Obstruction to urine flow in the maleObstruction to urine flow in the male

Residual urine after micturition:The time that elapses before the desire to pass

urine again becomes shorterInfection of the bladder: cystitis

Enlarged bladder & persistently high intraluminal pressures difficult for the ureters to empty: hydroureter hydronephrosisInfection ascend from the bladder

The final stage of prostatic enlargement complete inability to pass urine: acute retention of urine
