[Experiences in the treatment of benign prostatic hyperplasia with high power potassium-titanyl-phosphate (KTP) laser].

Unlabelled: Benign prostatic hyperplasia (BPH) exist in about 70% men after 60 years old. High power KTP laser is a new tool for the treatment of BPH.

Material And Method: 49 men were treated by photoselective vaporisation of the prostate (PVP) from August 2003 to May 2004.

[Value of the photodynamic method in the diagnosis of superficial bladder tumors].

Photodynamic diagnosis (PDD) is one of most precise method of neoplasms recognition. The aim of the study was to estimate the value of 5-amino levulinic acid in diagnosis of superficial bladder tumours. Since 1996 to March 2004, 597 cystoscopies were performed with 5-amino levulinic acid in 151 patients with superficial bladder tumours (102 men and 49 women) aged 19-87 years old.

Comparison of the bladder tumour antigen test with photodynamic diagnosis in patients with pathologically confirmed recurrent superficial urinary bladder tumours.

Objective: To verify the sensitivity of the bladder tumour antigen (BTAstat, Bard Urological, Covington, GA) test against the sensitive procedure of photodynamic diagnosis (PDD), in which 5-aminolaevulinic acid (5-ALA, a precursor of fluorescent porphyrins) is absorbed by the tumour and detected by ultraviolet cystoscopy, in the early diagnosis of urinary bladder tumours.

Patients And Methods: Forty-three patients (31 men and 12 women, age range 21-87 years) were assessed after transurethral resection of their bladder tumour using the BTAstat test and PDD. Sixty-nine biopsies from suspect areas of bladder mucosa were taken during cystoscopy under ultraviolet light and all suspect lesions electrocoagulated.
