[Comparison of transurethral surgical methods for treating small-size prostate hyperplasia]

To analyze different transurethral surgical methods for the treatment of small-size benign prostate hyperplasia (BPH) in order to improve the curative effect.

The clinical data of 52 cases of small-size BPH treated by transurethral surgery were reviewed and analyzed. Of the total number, 12 underwent transurethral prostate resection (TURP), 18 TURP plus transurethral incision of the bladder neck (TUIBN) and 22 TURP plus transurethral resection of the bladder neck (TURBN). The curative effect of the three different surgical methods was evaluated by international prostate symptom score (IPSS), maximum flow rate (Qmax) and post-voiding residual urine volume (PVR).

In the TURP group, 3 cases were complicated with contracture of the bladder neck, and the IPSS, Qmax and PVR were (12.2 +/- 3.2), (11.7 +/- 2.6) ml/s and (27.6 +/- 13.0) ml, respectively. In the TURP + TUIBN group, there was only 1 case of the complication and the three indices were respectively (8.6 +/- 3.2), (16.7 +/- 3.0) ml/s and (20.0 +/- 8.0) ml. No complication was observed in the TURP + TURBN group and the three indices were (6.2 +/- 3.0), (22.7 +/- 3.1) ml/s and (8.0 +/- 4.0) ml, respectively. No statistical difference (P > 0.05) was found in IPSS, Qmax and PVR among the three groups before the operation, but significant difference (P < 0.01) was observed after it. The curative effect was better in the TURP + TUIBN group than in the TURP, but was the best in the TURP + TURBN.

TURP + TURBN, being more effective than TURP + TUIBN, should be used as the first option for the surgical treatment of small-size BPH. The key to the operation is to thoroughly remove not only the hyperplastic gland but also the pathological changes of the bladder neck.
