Abstract

PURPOSE: Animal and clinical experiments have recently shown that TUEIP resulted in a reduction of the prostate volume and an increase of the lumen of the prostatic urethra. We assessed the clinical efficacy of TUEIP for BPH.
MATERIALS AND METHODS
Between February 2001 and December 2001, 27 patients diagnosed with BPH, and had undergone surgical management, were evaluated. With endoscopic injection set, 99% alcohol was injected into the inferior portion of the bladder neck and around the verumontanum, depending on the individual endoscopic findings. Pre-operatively, immediately after removal of the Foley catheter and at 3 months post-operatively, all the patients were evaluated with uroflowmetry and PVR, with 15 patients receiving transrectal ultrasound at 3 months post-operatively.
RESULTS
The pre-operative Qmax was 8.1ml/sec, which increased to 11.8ml/sec (p<0.05) after removal of the Foley catheter, and was further increased to 13.0ml/sec (p<0.05) at 3 months post-operatively. The pre-operative PVR was 14.2ml, which increased to 15.8ml and 16.5ml after removal of the Foley catheter and at 3 months post- operatively, respectively. The pre-operative prostate volume was 39.7cc, which was reduced to 25.9cc (p<0.05) at 3 months post-operatively. There was no systematic adverse effect from alcohol absorption.
CONCLUSIONS
TUEIP is considered as an effective alternative treatment of symptomatic bladder outlet obstruction caused by BPH, showing a significant increase in Qmax and reduction of the prostate volume.
