Analysis of surgical transurethral treatment for small-size benign prostatic hyperplasia

Objective To investigate the surgical methods of transurethral treatment for small-size benign prostatic hyperplasia (BPH) in order to improve the curative effect. Methods The clinical data of 52 cases of small-size BPH treated by transurethral operation were analyzed. Transurethral prostate resection (TURP) was underwent in 12, TURP plus transurethral incision of bladder neck(TUIBN) in 18, TUPR plus transurethral resection of bladder neck (TURBN) in 22. According to the International Prostate Symptom Score (IPSS), maximum flow rate (MFR) and post void residual urine volume (PVR), the curative effects were evaluated. Results In TURP group, the complication of bladder neck contracture occurred in 3 postoperatively. IPSS, MFR and PVR were 12.2±3.2, (11.7±2.6) ml/s, (27.6±13.0)ml,respectively. In TURP + TUIBN group, bladder neck contracture occurred in 1, and IPSS, MFR and PVR were 8.6±3.2, (16.7±3.0)ml/s, (20.0±8.0)ml,respectively, while in TURP+TURBN group, they were 6.2±3.0, (22.7±3.1)ml/s, (8.0±4.0)ml,respectively. There were no significant differences in these parameters (IPSS, MFR, PVR) among three groups before the operation (P0.05), but there were significant differences after the operation (P0.01). The curative effect in TURP+TUIBN group was better than that of TURP group, but TURP+TURBN group was the best. Conclusions Treatment of small size BPH by transurethral operation, TURP+TURBN is more effective than that of TURP+TUIBN, which should be the first surgical selection. The key of operation is to resect not only the hyperplastic gland but also the pathological changes of bladder neck thoroughly.
