Abstract:
Objective To analyze the significance of transrectal ultrasonography (TRUS) for diagnosis of BPH. Methods The data of 92 patients with dysuria were studied,including the case age,history,IPSS and serum PSA level.The volumes of total prostate and transitional zone were measured.The PK 1 and PK 2 of uretheral artery were determined by transrectal color Doppler,Q max and P detQmax were determined by urodynamics.Transitional zone index(TZI),resistive index(RI) and AG value were calculated. Results Correlation analysis showed that TZI( r=0.802,P =0.013),IPSS( r=0.704,P =0.023),RI( r=0.897,P =0.004) were significantly related to AG(AG=P detQmax -2Qmax).Multiple regression analysis showed that TZI and RI were relative factors of AG(R=0.947, R 2=0.897, 0.793, P =0.003),and the standard partial regression coefficients were 0.397( P =0.015) and 0.770( P =0.004),respectively.RI affected AG 1.94 times as significantly as TZI(0.770/0.397).Apart from effect of TZI,RI was the independant relative factor of AG( r=0.785,P =0.004). Conclusions Measurement of RI of prostate urethral artery and TZI by transrectal Doppler ultrasonography can offer valuable help for diagnosis of BPH.
