Perioperative and long-term results of retroperitoneal laparoscopic pyelolithotomy versus percutaneous nephrolithotomy for staghorn calculi: a single-center randomized controlled trial.

Purpose: To compare the perioperative and long-term outcomes of retroperitoneal laparoscopic pyelolithotomy (RLP) and percutaneous nephrolithotomy (PCNL) for the treatment of staghorn calculi.

Methods: From May 2011 to March 2017, eligible patients with staghorn calculi were randomly assigned to two groups: RLP and PCNL. Patients underwent the operations prospectively.

Uridine diphosphate-glucuronosyltransferase 2B15 D85Y gene polymorphism is associated with lower prostate cancer risk: a systematic review and meta-analysis.

UGT2B15 (uridine diphosphate-glucuronosyltransferase 2B15) catalyzes the conversion of lipophilic C19 steroid androgens such as dihydrotestosterone (DHT) into water-soluble metabolites that can be excreted. Studies of the association between the gene D85Y polymorphism and prostate cancer have yielded contradictory results. We therefore systematically searched in the PubMed, EMBASE, Science Direct/Elsevier, CNKI, and Cochrane Library databases, and identified six relevant studies with which to perform a meta-analysis of the relation between D85Y polymorphism and prostate cancer risk.

Improving doctor-patient communication: content validity examination of a novel urinary system-simulating physical model.

Effective doctor-patient communication is essential for establishing a successful doctor-patient relationship and implementing high-quality health care. In this study, a novel urinary system-simulating physical model was designed and fabricated, and its content validity for improving doctor-patient communication was examined by conducting a randomized controlled trial in which this system was compared with photographs. A total of 240 inpatients were randomly selected and assigned to six doctors for treatment.

Novel Transparent Urinary Tract Simulator Improves Teaching of Urological Operation Skills at a Single Institution.

Objective: This randomized controlled study compared a novel transparent urinary tract simulator with the traditional opaque urinary tract simulator as an aid for efficiently teaching urological surgical procedures.

Methods: Senior medical students were tested on their understanding of urological theory before and after lectures concerning urinary system disease. The students received operative training using the transparent urinary tract simulator (experimental group, n = 80) or the J3311 opaque plastic urinary tract simulator (control, n = 80), specifically in catheterization and retrograde double-J stent implantation.

CD4+CD25+ regulatory T cells-derived exosomes prolonged kidney allograft survival in a rat model.

CD4(+)CD25(+) regulatory T cells (Tregs) are negative regulators of the immune system that induce and maintain immune tolerance. Exosomes are natural products released from many sources and play a role in antigen presentation, immunoregulation, and signal transduction. In order to determine whether exosomes can be released from Tregs and participate in transplantation tolerance, we isolated and purified Tregs-derived exosomes and established a rat model of kidney transplantation.

Screening biomarkers of prostate cancer by integrating microRNA and mRNA microarrays.

Objective: In this study, we screened microRNA (miRNA) target genes of prostate cancer by integrating miRNA and mRNA expression profiles after target prediction and performed function enrichment analysis for selected candidate genes.

Methods: The miRNA expression profile (GSE36802) and mRNA expression profile (GSE36801) were downloaded from the Gene Expression Omnibus database. We processed data and identified the differentially expressed miRNAs and mRNAs with R packages.

Prolonged survival time of allografts by the oral administration of RDP58 linked to the cholera toxin B subunit.

Oral administration, which has been identified as a tool for boosting physiological immunoregulatory mechanisms in an antigen-specific manner, is a more convenient way than classical parenteral injection methods. RDP58 is derived from specific regions of class-I MHC molecules and is known to have immunomodulatory effects after intraperitoneal injection or intravenous administration. To determine whether the oral administration of RDP58 conjugated to the cholera toxin B subunit (CTB) can better induce peripheral tolerance than the use of traditional methods, we used various feeding regimens and methods of administration using equivalent doses of antigen during rat kidney transplantation.

[Effect of modified Badenoch operation on the treatment of posterior urethral stricture].

Objective: To determine the effects of modified pull-through operation (Badenoch operation) on the treatment of posterior urethral stricture.

Renal vein lengthening using gonadal vein reduces surgical difficulty in living-donor kidney transplantation.

Background: During living-donor kidney transplantation, to maximally decrease donor injury, the right kidney with lower glomerular filtration rate often is selected as the donor kidney. However, the renal vein of the right kidney is relatively short for transplantation. The gonadal vein is essentially useless and is easily accessed during the donor nephrectomy.
