Purpose: Urinary incontinence continues to be a significant problem for patients after radical prostatectomy. The male perineal sling is emerging as a safe and effective treatment option for postprostatectomy stress urinary incontinence. We compare the efficacy of porcine dermal collagen and silicone mesh as the sling material.
Materials And Methods: Of 36 patients with postprostatectomy stress urinary incontinence a porcine dermal collagen sling was placed in 20 and a silicone mesh sling was placed in 16. The sling was placed at the bulbar urethra and secured to 3 titanium bone screws anchored into the medial aspect of bilateral inferior pubic rami.
Results: Results at 12 months were compared. In the dermis group 9 (56%) patients were cured of incontinence (no pads daily), 5 (31%) had significant improvement (decrease of 50% or more in pads daily) and 2 (13%) had no change in symptoms. In the silicone mesh group 14 (87%) patients were cured of incontinence and 2 (13%) were significantly improved. Results showed that a previously placed artificial urinary sphincter led to poorer outcomes but a history of radiation therapy did not affect results. The most common complication was temporary urinary retention observed in 1 (5%) patient in the dermis group and 2 (12%) in the silicone mesh group.
Conclusions: Early results demonstrate that the male sling is a safe and efficacious treatment option for postprostatectomy urinary incontinence. This study demonstrates superior outcomes with the synthetic silicone mesh sling compared to the porcine dermal collagen.

The finite-element method (FEM) is a well-established procedure for computing approximate solutions to deterministic engineering problems described by partial differential equations. FEM produces discrete approximations of the solution with a discretisation error that can be quantified with a posteriori error estimates. The practical relevance of error estimates for biomechanics problems, especially for soft tissue where the response is governed by large strains, is rarely addressed.

The discharge of oil-laden wastewater from industrial processes and the frequent occurrence of oil spills pose severe threats to the ecological environment and human health. Membrane materials with special wettability have garnered attention for their ability to achieve efficient oil-water separation by leveraging the differences in wettability at the oil-water interface. These materials are characterized by their simplicity, energy efficiency, environmental friendliness, and reusability.

Background: This study aimed to investigate initial experiences and outcomes of a retrograde inserted new silicone-covered metallic ureteric stent (Urexel™) for malignant ureteric obstruction.
Methods: We retrospectively reviewed the medical records for 12 consecutive patients who underwent Urexel™ stent placement for malignant ureteric obstruction from March 2020 to March 2021. The Urexel™ stent is a segmental metallic ureteric stent composed of a nitinol mesh covered with a silicone membrane.

Iron oxide-impregnated filter papers (FeO) facilitate the study of soil phosphorus (P) desorption, availability and dynamics. However, many studies use homogenized and saturated shaking FeO soil systems, hindering opportunities to resolve environmentally relevant experimental objectives. This study created and evaluated a static microcosm to study soil P dynamics with FeO papers.

Background: Immediate breast reconstruction (IBR) with direct to implant (DTI) is the preferred method of reconstruction by many surgeons and patients, however, acellular dermal matrix (ADM) and other synthetic meshes are expensive especially in low- and middle-income countries. AIM OF THE WORK: To evaluate the technique, indications, aesthetic outcomes, and short and long-term complications of DTI breast reconstruction performed with Ultrapro®, a low-cost alternative mesh to ADM and other synthetic meshes.
Methods: Our study is a prospective cohort study that was conducted on 133 patients who experienced IBR following nipple-sparing mastectomy (NSM) or skin sparing mastectomy (SSM) using silicone implants and Ultrapro® mesh between December 2020 and December 2023.
