Departmental sources Background: Laparoscopic donor nephrectomy (LDN) has evolved and has been established as a surgical standard of care for kidney transplantation. Material/Methods: This study retrospectively reviews 1132 patients who underwent 4 different laparoscopic living-donor nephrectomies: hand-assisted laparoscopic nephrectomy (HALDN), pure laparoscopic donor nephrectomy (PLDN), laparoendoscopic single-site plus 1-port donor nephrectomy (LESSOP-DN), and mini laparoscopic donor nephrectomy (MLDN). Results: The mean estimated blood loss (EBL) for the HALDN group was meaningfully higher than those of LESSOP-DN and MLDN (57.5±52.2 mL versus 21.0±30.0 mL versus 18.2±28.7 mL) (P<0.001). The EBL for PLDN (53.3±35.3 mL) was also significantly higher than those of LESSOP-DN and MLDN (P<0.001). Length of stay (LOS) for HALDN was longer than that for LESSOP-DN (4.2±1.2 day versus 4.0±1.4 days, P=0.002). There was 1 intraoperative open conversion in the HALDN group and 2 HALDN surgeries that required postoperative exploratory laparotomy. LESSOP-DN had 3 (0.8%) postoperative incisional hernias. For recipients, the results revealed no significant differences between all 4 groups in terms of estimated glomerular filtration rate (eGFR) and the 1-year graft failure rate. Conclusions: The LESSOP-DN group was associated with a shorter incision length than those of HALDN and PLDN and shorter LOS than that of HALDN. Recipient results showed no meaningful difference regarding laparoscopic donor nephrectomy technique.

PurposeThe aim of this study was to investigate the anti-inflammatory and anti-oxidative effects of a multi-herbal formula known as WSY-1075 in the treatment of chronic bacterial prostatitis in a rat model.Materials and MethodsExperimental chronic bacterial prostatitis was induced in 32 Wistar rats by instillation of a bacterial suspension (Escherichia coli, 108 colony-forming units [CFU]/mL) into the prostatic urethra. After the induction of prostatitis, the rats were randomly divided into one of 4 treatment groups: control (n=8), ciprofloxacin (n=8), WSY-1075 (400 mg/kg) (n=8), and WSY-1075 (400 mg/kg)+ciprofloxacin (n=8). After 4 weeks of treatment, microbiological data from prostate tissue cultures, level of prostatic pro-inflammatory cytokines (tumor necrosis factor-α [TNF-α], interleukin [IL]-6, and IL-8), anti-oxidant effects (superoxide dismutase [SOD]), and histological findings were noted.ResultsThe WSY-1075, ciprofloxacin, and WSY-1075+ciprofloxacin groups showed fewer CFUs in prostate tissue cultures than the control group. The WSY-1075, ciprofloxacin and WSY-1075+ciprofloxacin groups showed statistically significantly lower levels of the pro-inflammatory cytokines TNF-α, IL-6, and IL-8 than the control group. SOD levels in the WSY-1075, ciprofloxacin and WSY-1075+ciprofloxacin groups were significantly higher than in the control group.ConclusionsThis study found that WSY-1075 had anti-microbial effects, anti-inflammatory effects, and anti-oxidative effects in a chronic bacterial prostatitis rat model. We expect the WSY-1075 may be useful for the clinical treatment of chronic bacterial prostatitis.

In this study, we attempted to characterize capsaicin's effects with regard to the apoptosis of murine bladder cancer cells (MBT-2) as well as the pharmacodynamics of nano-encapsulated capsaicin formulation for intravesical instillation. Materials and Methods: We assessed the viability of the MBT-2 cells via MTT staining, agarose gel electrophoresis, and flow cytometric apoptosis analysis. Intravesical reagents were instilled into 3 groups of male white New Zealand rabbits. Instillation agents were nano-encapsulated capsaicin dissolved in saline, capsaicin dissolved in saline, and capsaicin dissolved in dimethyl sulfoxide (DMSO). We also determined the pharmacokinetics of urine, plasma, and bladder tissue after intravesical capsaicin instillation. Results: Capsaicin treatment was determined to reduce cell viability in a time-and dose-dependent manner. The capsaicin concentrations in the urine of the rabbits decreased in each of the treatment groups, but we noted a more profound reduction of capsaicin concentration in the nano-encapsulated capsaicin group. Plasma concentrations were definitely lower as compared with the levels measured in the bladder tissue and urine. We noted distinctive differences in patterns of concentration change between the capsaicin with normal saline solution (NSS) or DMSO and the nano-encapsulated capsaicin groups. The concentration of nano-encapsulated capsaicin in the tissue appeared to increase directly with tissue depth. Conclusions: Our results show that capsaicin can induce apoptosis in MBT-2 cells, as well as the excellent permeation properties of nano-encapsulated capsaicin. Treatment with intravesical capsaicin may be a promising alternative therapeutic modality for the treatment of bladder cancer.
