Transurethral 2 μm continuous wave laser in treatment of prostatic hyperplasia with bladder stones: A report of 22 cases

Objective To study the clinical effect of transurethral 2μm continuous wave laser on prostatic hyperplasia with bladder stones. Methods Clinical data about 22 patients with prostatic hyperplasia accompanying bladder stones who underwent transurethral 2μm continuous wave laser operation in our hospital from March 2011 to June 2012 were retrospectively analyzed. Results The operation was successful in all the patients. The average age of the patients was 72 years (57-78 years). The average diameter of stones was 12 mm (3-20 mm). The average volume of prostates was 42.45 ml (28.05-92.95 ml). The average time of lithotrity with 2μm continuous wave laser was 28 min (9-46 min), the average operation time was 100 min (40-130 min), and the average time of indwelling catheter was 6 days (3-7 days) after operation. The patients were followed up for 3 -12 months after operation.The average international prostatic symptoms score (IPSS) decreased from 22 (14-31) before operation to 7 (3-11) after operation (t=-12.591, P＜ 0.01)．The Q_max increased from 4.0 ml/s (2.0-10.0 ml/s) before operation to 19.5 ml/s (15.0-24.0 ml/s) after operation (t=-14.111, P＜ 0.01). Conclusion Transurethral 2μm continuous wave laser lithotrity is a safe and effective procedure for elderly and highrisk patients with prostatic hyperplasia accompanying bladder stones.
