Bipolar transurethral resection of the prostate: the 'golden standard' reclaims its leading position.

Purpose Of Review: To summarize recent knowledge from experimental studies and randomized clinical trials in benign prostate hyperplasia that compare bipolar with monopolar transurethral resection, with an emphasis on morbidity.

Recent Findings: Bipolar transurethral resection of the prostate has a urodynamically proven efficacy to relieve bladder outlet obstruction, which seems to be durable in time with low long-term complication rates. The haemostatic capacity of bipolar current is shown to be superior in ex-vivo studies.

Keratin profiling in the developing human prostate. A different approach to understanding epithelial lineage.

Background: Keratin profiling studies in the developing human prostate have characterized cells thought to be stem cells and so-called intermediate cells. In a series of human prostates of various gestational ages, we extended on these studies using a comprehensive panel of keratin antibodies.

Materials And Methods: Autoptic tissue from 19 fetal prostates, gestational ages between 16 and 40 weeks, were immunostained with a panel of keratin antibodies: these recognize the luminal type keratins 7, 8, 18, 19, 20 and the basal/squamous type keratins 5, 6, 13, 14, 17.
