Clinical significance of prostatic-urethral angulation on the treatment outcome of patients with symptomatic benign prostatic hyperplasia treated with tamsulosin hydrochloride

To evaluate the impact of the prostatic-urethral angulation (PUA) on the treatment efficacy of selective alpha-1A receptor blocker in male patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia (LUTS/BPH).

A total of 80 patients with LUTS/BPH and with mean age 53. 3 ± 6. 3 (range 47-70) were included in our prospective comparative study. The patients were classified into 2 groups as a consecutive cases 40 in each one depending on the PUA either ≤ 35° (group A) or > 35° (group B). PUA and different prostatic parameters were measured using transrectal ultrasound. Prostate-specific antigen (PSA), the International Prostate Symptom Score and quality of life score (IPSS/QoL score), maximum flow rate (Qmax), and postvoid residual (PVR) volume were compared between the groups. The clinical significance of PUA was evaluated after 8 weeks of medical treatment with tamsulosin hydrochloride 0. 4 mg daily.

Baseline evaluation (pre-treatment) for both groups were comparable to each other with no clinically significant difference regarding age, PSA, IPSS/QoL score, Qmax and PVR volume (P-value > 0. 05). Comparison of parameters after 8 weeks showed that tamsulosin hydrochloride improved the total IPSS and all subscores (P < 0. 001), QoL (P = 0. 001), Qmax (P = 0. 002), and PVR (P = 0. 04) in group A (Table 1).

Tamsulosin hydrochloride appears to be less effective in improving IPSS/Qol score, Qmax and PVR in patients with lager PUA. The PUA might be a predictor for the treatment efficacy of α-blockers and more studies are warranted in the future before the final conclusion.
