To investigate the effects of transurethral resection of the prostate (TURP) on lower urinary tract symptoms (LUTS) in patients with benign prostatic hyperplasia (BPH) complicated by histological prostatitis.


This study included 432 cases of BPH pathologically confirmed after TURP. Excluding those with LUTS-related factors before and after surgery and based on the international prostatitis histological classification of diagnostic criteria, the remaining 144 cases were divided into groups A (pure BPH, n = 30), B (mild inflammation, n = 55), C (moderate inflammation, n = 31), and D (severe inflammation, n = 28). Each group was evaluated for LUTS by IPSS before and a month after surgery.


A total of 399 cases (92.4%) were diagnosed as BPH with histological prostatitis, 269 (67.4%) mild, 86 (21.6%) moderate and 44 (11.0%) severe. The preoperative IPSS was 21.43 +/- 6.09 in group A, 21.75 +/- 5.97 in B, 27.84 +/- 4.18 in C and 31.00 +/- 2.92 in D, with statistically significant differences among different groups (P < 0.001) except between A and B (P = 1.000); the postoperative IPSS was 5.60 +/- 2.16 in A, 7.36 +/- 2.77 in B, 11.55 +/- 3.39 in C and 16.89 +/- 3.37 in D, with statistically significant differences among different groups (P < 0.01), and remarkably lower than the preoperative one (P < 0.001). Almost all the infiltrating inflammatory cells in BPH with histological prostatitis were lymphocytes.


BPH is mostly complicated with histological chronic prostatitis. The severity of LUTS is higher in BPH patients with histological prostatitis than in those without before and after TURP, and positively correlated with the grade of inflammation. Those complicated with moderate or severe histological prostatitis should take medication for the management of LUTS.
