Uroflow nomogram for male adolescents.

Purpose: Uroflowmetry is well established for investigating lower urinary tract symptoms. Current nomograms are based on sample sizes limited to 8 men of the same age. We generated percentile curves for the maximum urinary flow rate (Qmax) in relation to voided volume in male adolescents in a large homogenous healthy group.

Long-term followup after laparoscopic nephropexy for symptomatic nephroptosis.

Purpose: Symptomatic nephroptosis is a rare disease requiring surgical therapy only in select cases. Laparoscopic nephropexy has been reported as minimally invasive treatment for symptomatic patients. We evaluated our long-term outcome after laparoscopic fixation of the kidney with an alloplastic mesh graft.

Variations of components of the plasminogen activation system with the cell cycle in benign prostate tissue and prostate cancer.

Background: Components of the fibrinolytic system are involved in tumor cell invasion and metastasis. Previous investigations suggested a cell cycle-dependent expression of urokinase-type plasminogen activator (u-PA) in epithelial cells. In order to determine a correlation of cell cycle phases with the fibrinolytic system, we investigated the expression of u-PA, tissue-type plasminogen activator (t-PA), and plasminogen activator inhibitor type 1 (PAI-1) in normal and tumor-containing prostate extracts and analyzed a possible relationship with flow cytometry-determined proliferative activity of the samples.

Analysis of fibrinolytic proteins in relation to DNA ploidy in prostate cancer.

The tissue concentrations of urokinase-type plasminogen activator (u-PA), urokinase-type plasminogen activator receptor (u-PAR), plasminogen activator inhibitor type 1 (PAI-1) and tissue-type plasminogen activator (t-PA) were investigated by an ELISA technique in normal and malignant samples of the prostate from 24 patients undergoing radical prostatectomy for organ-confined prostate cancer. The median concentration of u-PA was significantly higher in cancerous than in normal prostate tissue (p = 0.006).

Comparison of intraurethral liposomal and intracavernosal prostaglandin-E1 in the management of erectile dysfunction.

Objective: To compare the intraurethral application of liposomal prostaglandin-E1 (PGE1) with intracavernosal injection of PGE1 in patients with organic or psychogenic erectile dysfunction (ED).

Patients And Methods: Penile tumescence and rigidity were classified by palpation in 25 patients (10 with psychogenic and 15 with organic ED: median age 45 years, range 23-67). All patients were undergoing primary treatment for ED, the median (range) duration of which was 2 3 (2-44) months.
