[Endoscopic operations in invasive cancer of the urinary bladder].

Long-term results of conservative treatment of 153 patients with invasive cancer of the urinary bladder were studied retrospectively. The patients had stage T2 (n=121, 79.1%), T3 (n=26, 17%), T4 (n=6, 3.

[Application of resectoscope of Marberger type with cutting and vaporizing loops in the treatment of benign prostatic hyperplasia].

One of the latest achievement in the design of tools for TUR is introduction of a new resectoscope constructed by M. Marberger. Its oval loops can remove 30% more tissue than it is made by a standard resectoscope with semicurcular loops.

[Vaporizing resection - a new treatment of benign prostatic hyperplasia].

Though transurethral resection (TUR) remains a routine treatment for benign prostatic hyperplasia (BPH), its complications observed in up to 18% of patients necessitate active search for novel endoscopic methods. Vaporizing resection (VR) is among them. It makes use of two electrosurgical techniques of tissue removal--resection and vaporization--which provide adequate removal of the tissue and good coagulation.

[Electrovaporization in the treatment of bladder cancer].

Specialists of the Research Institute of Urology have practiced combination of transurethral resection (TUR) with electrovaporization in endoscopic treatment of bladder cancer (BC) since 1995. A total of 46 patients with transient cell BC (29 males and 17 females aged 49-87) stage Ta-T1 (32 patients) and T2-T3b (14 patients) underwent TUR or electrovaporization (if morphologically verified) of the exophytic part of the tumor. In addition, electrovaporization of the base of the tumor was made.
