Abstract

Recently transurethral incision of prostate (TUIP) is suggested to be a useful method in treating BPH weighting less 35gm, short prostatic urethra. mild bladder outlet obstruction by cystoscopy, and subjective obstructive symptoms with no concomitant prostate cancer. The therapeutic effects of TUIP is compared with those of transurethral resection of prostate (TURP) in small BPH (less than 35gm in weight). 1. The mean prostatic weight of TUIP group (14 cases) and TURP group (15 cases) was 23.9+/-7.2 gm and 25.3+/-7.1gm, each respectively. 2. Pre-and postoperative average flow rates were 4.1 and 10.3 ml/sec in TUIP group and 2.9 and 13.2 ml/set in TURP group. Pre- and postoperative maximum flow rates (MFR) were 7.4 and 13.0 ml/sec in the former and 5.6 and 19.4 ml/sec in the latter (p<0.01). 3. Voiding time (sec/100 ml) improved from 32.2 to 12.8 sec/100 ml in TUIP group and from 41.2 to 6.5 sec/100 ml in TURP group. The initiation time (sec) was shortened From 8.3 to 2.0 sec in the former and from 6.3 to 4.O sec in the latter. 4. In operative time, TUIP group necessitated 25+/-14 minutes, and TURP group. 52+/-10 minutes (p<0.001). 5. Mean duration of catheterization and hospitalization were 3.9 and 5.3 days in TUIP group, an 5.5 and 7.6 days in TURP group (p>0.05). 6. Improvements in the subjective symptoms were noted in 13 (92.2%) of 14 cases in TUIP group and 12 (80%) of 15 cases in TURP group. 7. In complications, l of hematuria requiring transfusion and 1 of incomplete incision in TUIP group and l of hematuria, 1 of retrograde ejaculation and 1 of urinary incontinence in TUIP group were experienced. In comparison to TURP. TUIP is easier in technique, less invasive with fewer complications and shows improvements in the subjective symptoms. Therefore. TUIP is a useful method in treating small BPH. especially in sexually active patients.
