Purpose: Transurethral resection of the prostate(TURP) is the gold standard treatment for symptomatic benign prostate hyperplasia, but significant complications are associated with this procedure. The aim of this study was to compare the standard TURP with the high power(80W) potassium-titanyl-phosphate laser(KTP/532; Greenlights PVTM laser system; Laserscope, San Jose, USA) to elucidate the efficacy and safety of laser treatment. Materials and Methods: We performed comparative trials of 40 patients suffering with symptomatic bladder outlet obstruction due to benign prostatic hyperplasia from February 2005 to June 2005. Twenty patients were treated with TURP(Group I) and 20 patients were treated with KTP (Group II). All patients were assessed preoperatively and at an interval of 3 months postoperatively based on the International Prostate Symptom Score(IPSS), the quality of life(QoL) index, changes in maximum urinary flow rate(Qmax), and the postvoid residual urine(ml). The safety parameters we evaluated included the operative time(minutes), the postoperative catheterization time(day) and the blood loss(ml). The Kolmogorov- Smirnov & Shapiro-Wilk test, Student's t-test, Student's t-test(paired), and Fisher's Exact test were performed for statistical analysis. Results: The mean age of each group was 68.9±9.9 years(group 1) and 63.9±9.7 years(group II), and the prostate weight was 49.5±15.4cc and 45.0±17.3cc, respectively. The mean operation time was shorter for group II(27.7±13.6min) than for group I(48.1±22.6min)(p<0.05). The mean catheterization time was 5.6±1.82 and 1.36±1.64 days, respectively, (p<0.001). The blood loss was lower in group II(11.7±11.4ml) than in group I(181.9±168.17ml, respectively)(p<0.001). Conclusions: In this preliminary short-term study, KTP Laser enucleation of the prostate was shown to be an effective alternative for treating benign prostate hyperplasia as compared with standard TURP

Purpose: The change of quality of life following a tension-free vaginal tape (TVT) and transobturator vaginal tape (TVT-O) procedure was investigated in patients with stress urinary incontinence. Materials and Methods: We included 86 women with stress urinary incontinence who underwent the TVT or TVT-O procedure and followed up for at least 1 year. Preoperatively, the patients were evaluated with history taking, physical examination, urodynamics to determine abdominal leak point pressure (ALPP) and pre- and postoperative quality of life was evaluated by incontinence quality of life questionnaire (I-QoL). The success after operation was defined as the absence of any subjective complaint of leakage. Results: The rate of cure of TVT and TVT-O procedure were 84%, 92% and the rate of improvement of them were 16%, 8%, respectively. Preoperative patient characteristics including uroflowmetric parameters and ALPP were comparable in the two groups. The I-QoL parameters one year after surgery were statistically significant increase in I-QoL scores in each groups. There were no serious or long-term complications related to both procedures. Conclusions: These data suggest that the TVT and TVT-O procedure are effective for treating female stress incontinence and also in the aspect of improving quality.
