Abstract

There is currently a renewed interest in laser in the field of urology, essentially for the treatment of benign prostatic hypertrophy, as a result of recent developments in the field of fibres. Laser is light coherent in time and space emitted continuously or in pulses. Only its thermal and photochemical properties are used in urology. Endoscopic coagulation of superficial bladder tumours by Nd YAG laser does not seem to be better than classical endoscopic resection, at the present time, as although it is less haemorrhagic, it does not decrease the recurrence rate. Photochemotherapy of bladder carcinoma in situ still constitutes a complex treatment protocol reserved for specialized centres. Lastly, upper urinary tract tumours can be treated by Nd YAG laser coagulation, in rare indications which are the same as those of ureteroscopic or percutaneous resection. The recent development of lateral firing laser fibres and contact tip fibres has led to a renewed interest in laser in benign prostatic hypertrophy. Two different techniques have been proposed: Nd YAG laser coagulation under direct visual or ultrasound control (TULIP), which gives delayed objective results (two or three months) and contact tissue vaporization (Nd YAG, diod...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Bladder Carcinoma In Situ

Bladder Carcinoma In Situ is a superficial bladder cancer that occurs on the surface layer of the bladder. Discover the latest research on this precancerous condition in this feed.
