What are complementary exams in BPH?

PSA Rate (detect cancer associated w/BPH, if >4 indication for biopsy, specific for prostate gland but not cancer, can increase w/infection, ejaculation, age...) Creatinine (evaluate UUT and detects renal insufficiency) Cytobacterial exam of urine (eliminates any infection presence, can be eliminated by absence of leukocytouria and negative uroculture) Urodynamic Tests Measuring Flow (debimetry, Measures flow quantifies dysuria, volume must be >150 ml, sees volume, max flow, average flow and mictionnel, bell-shaped curve normal, flattenned is for obstruction/BPH max flow rate 10ml/s) US (sees repercussion on UUT see bilateral dilations of pyelocaliceal cavities thinning of renal parenchyma, impact on LUT detrusor hypertrophy, bladder diverticula, stones, post-void residue, prostate US transrectal/suprapubic, see volume and median lobe) Others (bladder fibroscopy, neuro bladder exam)
