Résumé
Objective To explore the feasibility of tubeless 2 μm laser vaporesection in treating pediatric ureter cysts by ureteroscopy.MethodsClinical data of 33 ureter cysts patients who received tubeless 2 μm laser vaporesections by ureteroscopy were reviewed. The median age of patients was 4 years with a range from 1 to 7 years. The operations were carried out by RevoLix 2 μm laser through ureteroscopy without ureter stents and catheters indwelling.ResultsAll operations were successfully performed. And no serious complications occurred after the operations.ConclusionsTubeless transurethral 2 μm laser treatment by ureteroscopy was a superior micro-invasive surgery method for pediatrics with ureter cysts, with advantages of little blood loss, high safety, convenient operation and infrequent complications.
Résumé
Objective To investigate the clinical efficacy of RevoLix 2 μm continuous wave laser treatment on bladder neck contracture after benign prostatic hyperplasia operation. Methods A total of 21 cases were enrolled in current research and they all accepted 2 μm continuous wave laser treatment of bladder neck contracture after benign prostatic hyperplasia operation in the 252th Hospital of the Chinese People's Liberation Army. The clinical efficacy was recorded. Results The operation of the 2 μm continuous wave laser vaporesections were successfully performed on 21 cases. The maximum urine flow rate was increased from(6. 86 ± 1. 97)ml/ s to(16. 31 ± 1. 61)ml/ s,and the difference was significant(t = 15. 49,P < 0. 01). After 3 to 23 months(median 14 months)follow-up,20 cases were cured and 1 case was combined with bladder residual urine 110 ml. Conclusion The therapy of 2 μm continuous wave laser is a superior micro-invasive surgery method for patients with Bladder neck contracture,which shows little blood loss,high level safety,convenient operation and infrequent complications.
