To enhance the treatment of patients' urethral defects, such as strictures and hypospadias, we investigated the potential of using artificial urethral tissue. Our study aimed to generate this tissue and assess its effectiveness in a rabbit model. Two types of bioprinted grafts, based on methacrylated gelatin-silk fibroin (GelMA-SF) hydrogels, were produced: acellular, as well as loaded with autologous rabbit stem cells.

Material And Methods: Between 2002 and 2007, a pT3a stage after radical prostatectomy was detected in 126 patients at our institution. Kaplan-Meier analysis was used to calculate OS, CSS, DPFS and BPFS.
Article Synopsis
- Prostate cancer with a Gleason score of 6 is common in biopsies, and this study aimed to understand why some tumors are graded higher after surgery.
- The research involved 241 patients who had surgery for Gleason score 6 cancer, analyzing various clinical factors to see what might predict an upgrade in Gleason score.
- Results showed that about 38.2% of patients had their scores upgraded after surgery, with prostate weight and PSA density being significant predictors of this upgrade along with increased risk of more serious cancer features.
Objectives: To predict bladder outlet obstruction with parameters of non-invasive investigations for patients with symptomatic benign prostatic hyperplasia.
Patients And Methods: A sample of 122 men with moderate to severe lower urinary tract symptoms suggestive of benign prostatic hyperplasia was selected. Transrectal prostate ultrasound, free flow measurement, and transabdominal ultrasound for residual urine were carried out together with digital rectal examination for all patients.
