The Clinical Application Of2μm Laser Treatment Of Bladder Stones

PurposeBladder stones are one of the common urological diseases, except for a few primary mostly due to malnutrition, the majority of mostly secondary to benign prostatic hyperplasia, urethral stricture, bladder diverticulum, neurogenic bladder dysfunction, foreign objects or kidney, ureter into the bladder stones. The clinical symptoms of urinary frequency, urinary suddenly interrupted, hematuria, dysuria, pain, there will be severe recurrent infections, and even cancer. Therefore, the absolute indications for surgery bladder stones is surgical intervention, as the technology continues to mature cavity, the vast majority of bladder stones can be minimally invasive endovascular surgical rubble. We use new technology that2μ m thulium laser laser treatment of bladder stones, urinary bladder stones explore the clinical application of2μ m laser treatment efficacy and safety.MethodJanuary2012to July2013, Tianjin Medical University General Hospital collected30patients with bladder stones, transurethral application2μ m laser treatment, surgery using saline as fluid analyzed preoperative and perioperative data, the recording operation overall time, blood loss, postoperative washing time, postoperative indwelling catheter time, maximum flow rate change (maximum flow rate, Omax), postoperative complications, the average light time, the average optical power, before and after surgery were compared with paired t test for statistical analysis, postoperative stone composition analysis, and evaluate the efficiency of gravel.Result30patients were successfully operated. The mean operative time (25±5) min, gravel almost no bleeding during surgery, bladder flush time (12-24) h,, indwelling catheter1-2d, patients without blood transfusion, infection, fever, one case; Average gravel Idemitsu time (14.7±5.4) min, gravel total power (30.30±1.65), the main component mainly calcium oxalate stones, uric acid and hydroxyapatite-based,2u m laser has a high temperature gasification gravel stones role were followed up for2to6months, review and no residual stone recurrence, Qmax from the preoperative (7.1±0.5) mL/s increased (18.2+1.6) ml/S, the difference before and after surgery was statistically significant (P<0.05).Conclusion1.2μ-m laser transurethral bladder stone lithotripsy, is one of the most cutting-edge treatment of bladder stones, rich choice of endovascular minimally invasive surgery, on the application of2μ m laser treatment of bladder stones has not been reported at home and abroad, innovative exploration significance.2.2μm laser effects of various types of stones are crushed, gravel and stone row efficiency rate, postoperative specimens to be analyzed and statistics, bladder stones ingredients are calcium stones, phosphate and uric acid salt-based form mostly mixed urinary stones, stones periodic summary highly selective nature of the corresponding laser output power, thereby increasing the efficiency of rubble,3.transurethral bladder stones while2μ m laser treatment can be lifted due to the obstruction caused by benign prostatic hyperplasia causes of bladder tumor resection and continuity of operations, with no need for other equipment, shorten operative time, less blood loss, surgical trauma, surgery after recovery, simple operation, easy to master, etc. safe and effective, especially for the elderly or high-risk patients and for various reasons can not be routine surgery the patient, a better prospect, worthy of clinical application.
