[Combined transurethral procedure for bladder outlet obstruction induced by small-volume prostatic hyperplasia]

To investigate the clinical effect of transurethral resection of the prostate(TURP) combined with transurethral incision of the bladder neck( TUIBN) in the treatment of bladder outlet obstruction( BOO) caused by small-volume benign prostatic hyperplasia( BPH).

We retrospectively analyzed the clinical data about 56 cases of small-volume BPH. The patients,aged 45- 71( mean 59. 6) years,all showed varied degrees of dysuria and 20 of them had a history of chronic prostatitis. Preoperative examinations included the obtainment of International Prostate Symptom Score( IPSS),evaluation of the quality of life(QOL),ultrasonography, urodynamic examination, and cystoscopy. All the patients received alpha-blockers for 3- 6 months without obvious response and therefore underwent TURP + TUIBN.

Postoperative follow-up lasted 12- 24 months. Urinary tract stricture was found in 2 cases(3. 57%) at 1 month after surgery, which was improved after urethral dilation,and bladder neck contracture occurred in 1 case(1. 79%) at 3 months, which was relieved by repeated TUIBN. Compared with the baseline, the IPSS was dramatically decreased at 12 months postoperatively(25. 54 ± 2. 33 vs 12. 76 ± 2. 37,P < 0. 01),and so was the postvoid residual([68. 07 ± 17. 09]vs [31. 02 ± 9. 75] ml. P < 0. 01),while the maximum urinary flow rate(Qmax) was significantly increased([8. 47 ± 0. 96]vs [15. 83 ± 1. 47]ml/s, P < 0. 01).

TURP + TUIBN is superior to either TURP or TUIBN alone in the treatment of BOO induced by small-volume BPH for its higher effectiveness and safety.
