Abstract
This is the first North American report describing the use of the holmium:YAG (Ho:YAG) laser to treat patients with superficial bladder carcinoma. Fifteen patients, with a total of 52 recurrent superficial bladder tumors, underwent endoscopic laser photoablation of their lesions. No intraoperative or delayed complications occurred. At followβup cystoscopy performed 3 months after lasing, four patients (27%) were without disease; eight patients (53%) had outβofβfield recurrences; and three patients (20%) were classified as having inβfield recurrences. We conclude that using the Ho:YAG for endoscopic treatment of patients with superficial bladder tumors is both feasible and clinically useful and that the lack of perceived pain or discomfort during lasing, as well as the lack of need for an inβdwelling urethral catheter, makes it advantageous for selected patients over conventional electroresection techniques.

## Abstract ## Background and Objectives The feasibility of treating upper urinary tract tumors with a holmium:YAG (Ho:YAG) laser in transurethral endoscopy was examined. ## Study Design/Materials and Methods Thirtyβthree treatments were performed on 30 patients with renal pelvic and ureteral ca
Complications resulting from the use of the neodymium:YAG (Nd:YAG) laser to treat superficial bladder cancer are uncommon and are usually associated with abnormally high laser power outputs. We report a case of bladder perforation in a human attributed to the Nd:YAG laser used at a low power setting
## Abstract ## Background and Objectives Surgical resection of hepatocellular carcinoma (HCC) is not always regarded as the first choice of treatment, because most HCCs develop in cirrhotic liver. It becomes adaptation of minimally invasive treatments for HCC. In animal experiments, we previously
Ureteroscopy offers an extension of endoscopic diagnosis and treatment to upper urinary tract malignancy. Combination of ureteroscopy and the NdYAG laser permits accurate and effective treatment of ureteral neoplasms. Nine highly selected patients, six males and three females, were treated with low
