Effects of benign prostatic hyperplasia

Effects of benign prostatic hyperplasia

It is important to realise that the relationship between anatom - ical prostatic enlargement, LUTS and urodynamic evidence of BOO is complex ( Figure 84.2 ). Summary box 84.2 Consequences of BPH /uni25CF /uni25CF /uni25CF /uni25CF /uni25CF

No symptoms, no BOO No symptoms, but urodynamic evidence of BOO LUTS, no evidence of BOO LUTS and BOO Others (acute/chronic retention, haematuria, urinary infection and stone formation)

Anatomically , the e ff ects are as follows: /uni25CF Urethra . The prostatic urethra is lengthened, sometimes to twice its normal length, but it is not narrowed anatom ically . The normal posterior curve may be so exaggerated that it requires a curved catheter to negotiate it. When only one lateral lobe is enlarged, distortion of the prostatic ur thra occurs. /uni25CF Bladder . If BPH causes BOO, the musculature of the bladder hypertrophies to overcome the obstruction and ap pears trabeculated ( Figure 84.3 ). Significant BPH is asso ciated with increased blood flow , and the resultant veins at the base of the bladder are apt to cause haematuria.
