ABSTRACT

Objective To evaluate the efficacy and safety of retroperitoneal laparoscopic pyelolithotomy ( RLP) combined with holmium laser lithotripsy under flexible cystoscopy in the treatment of complicated nephrolithiasis. Methods The retrospective analysis was made on the clinical data of 37 patients who underwent RLP and holmium laser lithotripsy under flexible cystoscopy for complicated nephrolithiasis from January 2013 to January 2014. The clinic parameters involved basic data of patients,operational time,blood loss,post-operative hospital stay,the status of stone-free,perioperative complications,and the follow-up data of patients were observed. Results No patient was converted to open surgery. The mean stone size was (2. 8 ± 0. 9) cm in diameter,operational time was (89 ± 24) min,blood loss was (21. 3 ± 7. 7) mL,post-operative hospital stay was (6. 8 ± 1. 7) d,the stone removal rate in one session was 94. 6%. One case occurred urinary leakage,1 case occurred fever after operation,who were all recovered through conservative treatment. All cases were followed up at the sixth months after operation. Conclusion RLP combined with holmium laser lithotripsy under flexible cystoscopy is effective and safe for the treatment of com-plicated nephrolithiasis.

ABSTRACT

This article describes a novel Multifunctional and Transparent Urinary System Model (MTUSM), which can be applied to anatomy teaching, operational training of clinical skills as well as simulated experiments in vitro. This model covers kidneys, ureters, bladder, prostate, male and female urethra, bracket and pedestal, etc. Based on human anatomy structure and parameters, MTUSM consists of two transparent layers i. e. transparent organic glass external layer, which constraints the internal layer and maintains shape of the model, and transparent silica gel internal layer, which possesses perfect elasticity and deformability. It is obvious that this model is preferable in simulating the structure of human urinary system by applying hierarchical fabrication. Meanwhile, the transparent design, which makes the inner structure, internal operations and experiments visual, facilitates teaching instruction and understanding. With the advantages of simple making, high-findelity, unique structure and multiple functions, this model will have a broad application prospect and great practical value.

ABSTRACT

Objective To compare the efficacy and safety of twice-daily tacrolimus (Tacrolimus BID; Prograf) vs once-daily prolonged release tacrolimus (Tacrolimus QD; Advagraf), combined with steroids and mycophenolate mofetil in preventing acute rejection in De Novo renal transplantation patients. Methods 241 patients from 11 centers were randomized into two groups with 3 months observation period post-transplantation. Advagraf was administered as a single oral dose in the morning (initially 0. 1-0. 15 mg/kg every day) and Prograf was administered in two equal oral doses 12h apart (initially 0. 1-0. 15 mg/kg). Study visits were scheduled for days 1, 3, 7, 14, 28, 56, 84post-transplantion. The efficacy, safety, compliance and adverse effects were compared between two groups. Results Totally 223 patients completed the study. The two groups were comparable in age,gender and primary disease. There were 12 episodes of acute rejection in each group. There was no graft loss or patient death in both groups. The incidence of drug related adverse events was 32. 1 %and 33. 3% respectively in the control and experimental groups. Dosage was decreased in both groups and there was significant difference in each group. The trough level was similar at the initiate period.Twenty-eight days post-transplantation the trough level in the Advagraf group was lower than in the Prograf group. Conclusion Advagraf has the same efficacy, safety and drug related adverse effects as Prograf. It is practical and feasible for Advagraf substitute for Prograf in clinical practice.

ABSTRACT

Objective To investigate whether reduced or discontinued calcineurin inhibitor (CNI) can improve the renal functions of renal transplant recipients with chronic allograft nephropathy (CAN). Methods A total of 46 renal transplant recipients with declining graft function and biopsy proven CAN were studied. Within 1~2 weeks, CNI (Cyclosporine A or Tacrolimus ) in 27 recipients (group A) was discontinued or reduced to one third of their original doses, but Azathioprine (Aza) or mycophenolate mofetil (MMF) was increased properly. The doses of CNI in the 19 recipients (group B) were not changed obviously, but Aza or MMF was increased properly. At least 1-year follow-up was performed in all patients. Renal functions were compared between the two groups. The incidence of acute renal graft rejection was calculated in both groups. Results One year later, there were 17 patients (63.0%) with stabilized or improved graft function in group A, and 2 (10.5%) in group B. The difference was significant. The incidences of acute rejection in both groups were not significantly different. Conclusion For some renal transplant recipients with declining graft function and biopsy proven CAN, remarkably reduced or discontinued CNI can stabilize or improve their renal functions. Adjusting the doses of immunosuppressive agents does not increase the risk of acute rejection.

ABSTRACT

Objective To investigate the protective effect of calcium antagonist Verapamil (VP) on kidney preservation in HCA solution. Methods After kidneys were isolated from rabbits, they were perfused and stored in HCA solution or in HCA solution with VP pre-supplement at 4℃ for 24 h respectively. The contents of mitochondrial calcium in renal cells and ATP in renal tissues were measured in every group. Results The contents of mitochondrial calcium was remarkably higher and ATP significantly lower in the kidneys in HCA solution at 4℃ for 24 h than those just after resection. But these could be inhibited in those storing in the HCA solution with VP pre-supplement. Conclusion Calcium antagonist VP can protect kidney function during HCA solution preservation by inhibiting calcium intaking into mitochondrium.
