painful micturition, and difficult micturition
pain on voiding typically from urethral, bladder or vaginal inflammation, UTI? May also be STI, prostatitis. Rare causes= stones, urethral lesions e.g. carcinoma.
voiding difficulty= outflow obstruction e.g. BPH, urethral stricture e.g. post-gonococcal.
what is freqency?
voiding more often.
frequent passage of small amounts of urine could be due to cystitis, urethritis, neurogenic bladder.
or bladder compression or outflow obstruction e.g. bladder tumour, enlarged prostate.

urine output <400ml/24hr- sign of shock or acute renal failure
what is anuria?
no urine output
<50ml/24hr e.g. renal stones
what is polyuria?
increase in urine volume, >3L/24hr
could be due to diabetes mellitus and insipidus, giving too much IV fluids
what is urinary incontinence?
involuntary leakage of urine

normal urine doesn’t really smell
old urine= ammonia
fishy smell= infection
pear drops= ketotic urine in type 1 diabetes mellitus
