Background : To evaluate the preliminary safety, efficacy and complications of transurethral resection (TUR) in the management of women with lower urinary tract symptoms. Methods : One hundred and eight women (mean age, 57.6 years) with moderate to severe lower urinary tract symptoms underwent TUR between September 1998 and December 2002. At preoperative baseline, 6 months and 24 months postoperatively, all patients underwent clinical evaluations including the standardized American Urological Association symptom score, peak urine flow, postvoid residual urine volume and quality-of-life assessments. Operative time, catheter time, hospital stay and incidence of side-effects were also recorded.Results : The total mean operative time was 19.25 ± 6.70 min. The mean catheter time was 26.2 ± 12.8 h and the mean hospital stay was 2.08 ± 0.84 days. No patient needed a blood transfusion or experienced hyponatremia. The total storage and voiding symptom scores and quality of life score had improved significantly 6 months after the surgical procedure (P < 0.01). There were little changes in peak flow rate and residual urine volume. Complications of the procedure included urinary tract infections (n = 4) and stress incontinence (n = 3). Two patients later underwent bladder neck suspension procedure. Conclusions : In this preliminary study, there was significant clinical improvement maintained at all follow-up intervals and the results were not comparable to TUR of the prosatate in men with clinical benign prostatic hyperplasia. The risks associated with TUR in women, especially of stress incontinence, are significant. A multicenter clinical trial is currently underway to determine the long-term efficacy and safety of TUR in women.
