A clinical study on 3D virtual model-assisted precise navigation for laparoscopic partial nephrectomy.

Background: Laparoscopic partial nephrectomy (LPN) is a standard surgical treatment option for renal tumors. Prior to LPN, it is necessary to evaluate the tumor condition and develop a surgical plan using precise imaging.

Objective: To explore the clinical application value of 3D virtual model (3DVM) in LPN.

Efficacy of Phosphodiesterase-5 Inhibitor in Men With Premature Ejaculation: A New Systematic Review and Meta-analysis.

Objective: To clarify the efficacy of phosphodiesterase-5 inhibitor (PDE5i) in men with premature ejaculation (PE).

Methods: We searched the PubMed, Embase, and Cochrane Library databases to identify all randomized controlled trials and compared results, including intravaginal ejaculation latency time, satisfaction, side effects, and others, after treatment with PDE5i vs placebo, PDE5i vs selective serotonin reuptake inhibitor (SSRI), or combined use of PDE5i with SSRI vs SSRI alone for treating PE.

Results: The study inclusion criteria were met by 10 studies (10 randomized controlled trials with 3 crossover studies) involving 775 patients.
