30 minutes high energy transurethral microwave thermotherapy (30 minutes TUMT) for the treatment of chronic urinary retention in patients with ASA II-III-IV.

Objective: To investigate if 30-Minutes-TUMT was useful and safe in the treatment of chronic urinary retention due to BOO in patients with ASA II-III-IV.

Material And Methods: 19 patients with chronic urinary retention (mean age 73.5 years) were scheduled for TUMT treatment because of absolute or relative contraindications to surgery.

Is it possible to predict post-residual voided urine by bladder scan before uroflowmetry--a useful and timesaving test to reduce the number of non--evaluable uroflow measurements?

Objectives: Bladder-scan before uroflowmetry is useful to reduce non-evaluable Q(max)-data. A significant problem is to receive an adequate voided volume in uroflow-measurements. Aims of this study were 1--to confirm if pre-voiding bladder scan can reduce the number of inadequate flow measurements, 2--to establish threshold values for prevoiding bladderscan volumes before and after different treatments options 3--to study if it is possible to predict the post-residual voided volume.

Immunosuppression in renal cancer: differential expression of signal transduction molecules in tumor-infiltrating, near-tumor tissue, and peripheral blood lymphocytes.

Alterations in the expression of signal activation molecules, such as the T-cell receptor (TCR) zeta and epsilon chains and p56lck tyrosine kinase, are described in tumor-infiltrating lymphocytes (TIL). The aim of this study was to ascertain if such molecules were present in near-tumor-tissue lymphocytes (NTTL) and peripheral blood lymphocytes (PBL), as well as TIL, of renal cell carcinoma patients, to verify whether this tumor induces immunosuppression only locally or affects distant lymphocytes as well. Tissue from the tumor and from healthy nearby sites, as well as blood samples, were obtained from 27 consecutive patients who had undergone radical nephrectomy for renal cell carcinoma.

Spleen-preserving total pancreatectomy with conservation of the spleen vessels:: operative technique and possible indications.

Conventional distal pancreatectomy (cDP) and total pancreatectomy (cTP) also involve removal of the spleen. The spleen, however, is an important organ in the immunologic defense of the host and is worthy of preservation if this can be safely achieved. We performed a spleen-preserving total pancreatectomy (SPTP), with good results, in a Caucasian woman, 66-year-old, affected by pancreatic metastases of renal clear cell carcinoma.

Usefulness of a prevoiding transabdominal sonographic bladder scan for uroflowmetry in patients involved in clinical studies of benign prostatic hyperplasia.

Objective: Flow rate measurements in clinical studies require an amount of voided urine greater than 125 to 150 mL. Often patients do not void sufficient amounts of urine, and having them produce repeated flows is often difficult. Transabdominal sonographic scanning of the bladder is a simple method for estimating bladder volume.
