Randomized prospective trial comparing ejaculatory preservation HoLEP versus standard HoLEP: the other face of the coin.

Background: Laser Anatomical Endoscopic Enucleation of the Prostate (LAEEP) techniques offer a promising solution for patients seeking to alleviate urinary symptoms while preserving sexual function. The ejaculation preservation approach has been shown to achieve an impressive 90% success rate in maintaining antegrade ejaculation.

Purpose: To explore the effect of the ejaculatory preservation HoLEP technique on postoperative continence and ejaculation.

Erosion of rigid plastics in turbid (sandy) water: quantitative assessment for marine environments and formation of microplastics.

Mechanical degradation (erosion) of plastics in the marine environment has been reported in many literature studies but without quantitative information. This type of degradation is crucial as it accounts for most of the initial microplastic products, in marine environments (, rivers and oceans). Here, we quantify the erosion of plastics by water-borne sediments under typical perpendicular water velocities and sand loads of turbid rivers and coastal oceans.
