After 1, 2, weeks, six rats control group...
Effective therapies for erectile dysfunction (ED) associated with diabetes mellitus (DM) are needed. In this study, the effects of stromal cell-derived factor-1 (SDF-1)-expressing engineered mesenchymal stem cells (SDF-1 eMSCs) and relevant mechanisms in corpus cavernosum a streptozotocin (STZ)-induced DM ED rat model were evaluated. randomized controlled trial, Sprague–Dawley (SD) rats (n = 48) divided into four groups 12/group): Normal (control), (diabetes induced by STZ), + BM-MSC...
Abstract Background This study aims to evaluate the effect of extracorporeal shock wave therapy (ESWT) on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and explore mechanism. Methods RWPE‐2 cells were randomly divided into three groups: (a) group (normal control), (b) LPS groups (lipopolysaccharide inducing inflammation) (c) ESWT (LPS induced treated by ESWT). After was administered, supernatant collected for enzyme‐linked immunosorbent assay (ELISA) Western blot analysis. In...

Purpose: To investigate the efficacy and safety of single-port (SP) robotic transperitoneal (TP) retroperitoneal (RP) partial nephrectomy. Materials Methods: We sequentially analyzed 30 nephrectomy performed after SP robot was introduced to hospital in September 2021 June 2022. All patients were found have T1 renal cell carcinoma (RCCs) operated by a single expert conventional with da Vinci platform. Results: Total underwent 16 (53.33%) TP approach 14 (47.67%) RP. Body mass index slightly...
Purpose: The aim of the present study was to evaluate efficacy and safety electromagnetic-type low-intensity extracorporeal shock wave therapy (Li-ESWT) in patients with erectile dysfunction (ED).Materials Methods: randomized, sham-controlled, double-blind prospective performed at two referral hospitals.Participants were randomized a 1:1 ratio receive sham or Li-ESWT for 6 weeks.ED evaluated screening 4 7 weeks after treatment.Participants asked complete international index function-erectile...
A novel urolithiasis treatment in which a chelating solution encapsulated poly(lactic-co-glycolic acid); PLGA-based microcapsules was delivered magnetically to specific sites and then subjected ultrasound (US) release the dissolve stones. Using double-droplet microfluidics method, hexametaphosphate (HMP) an Fe3O4 nanoparticle (Fe3O4 NP)-loaded PLGA polymer shell with thickness of <15 μm, forming homogenous 319 ± 14 μm size. The obtained (HMP/Fe3O4@PLGA) exhibited efficient magnetic mobility...
To compare the surgical results of retroperitoneal (RP) robot partial nephrectomy (PNx) using either a single-port (SP) or multi-port (MP).
Background and Objectives: This study evaluated the safety efficacy of long-term indwelling self-expandable covered metallic stents (UVENTA; Taewoong Medical Co., Ltd., Seoul, Republic Korea) used to manage benign malignant ureteral strictures. Materials Methods: We retrospectively identified analyzed medical records all patients who underwent stent insertion at our institution since September 2012. Additionally, we technical clinical success rates complications follow-up for more than 36...
Purpose: We examined the association between obesity and prostate cancer both with without diabetic patients included in analysis using nationally representative data of Korean population from National Health Insurance System (NHIS). Materials Methods: Of 424,712 participants who underwent health examinations 2002-2008, 139,519 men ≥40 years old were followed beginning 2002 to end 2012. Multivariate adjusted Cox regression was conducted examine hazard ratio (HR) 95% confidence interval (CI)...
