Five-year effectiveness of low-dose-rate brachytherapy: comparisons with nomogram predictions in patients with non-metastatic prostate cancer presenting significant control of intra- and periprostatic disease.

Purpose: To assess the effectiveness of low-dose-rate (LDR) brachytherapy in patients with localized prostate cancer and to compare the outcome with predictions from Kattan and Partin nomograms at 60 months after seed implantation.

Material And Methods: One thousand, one hundred and eighty-seven patients with localized prostate cancer at low-, intermediate-, or high-risk of progression received LDR brachytherapy using iodine-125 seeds with curative intent, applied as monotherapy or in combination with external beam radiation therapy (EBRT), and/or androgen deprivation therapy (ADT). At 60 months after seed implantation, data of 1,064 patients (1,058 alive + 6 who died of prostate cancer) were analyzed for biochemical progression-free survival (bPFS) based on prostate-specific antigen (PSA) levels using the Phoenix definition.

Urinary leakage of tubular enzymes after shock wave lithotripsy.

Objectives: Urinary loss of tubular marker enzymes following shock wave lithotripsy (SWL) suggests corresponding morphological changes in the kidney. To date, the morphological correlate of enzymuria and its dependence on the energy applied remains unclear.

Methods: In an animal study, the acute morphological changes occurring in the tubulus cells as the basis of enzymuria were investigated.
