Kidney transplantation has been known as a major advancement of modern medicine which provides high-quality life years to patients with irreversible kidney failure (end-stage renal disease, ESRD) worldwide. The first kidney transplantation in Semarang was carried out at Telogorejo Hospital in 1985. Dr. Kariadi Hospital, has also undertaken kidney transplantation 28 times since January 2014 until September 2018. Kidney ischemic time is one of the most important factors which can affect the outcome of kidney transplantation. Prolonged ischemia of the graft can be related to transplantation’s effects. This study aimed to evaluate the influence of warm and cold ischemic time on the outcome of kidney transplantation in Dr. Kariadi Hospital Semarang.

Material and Methods:

This is an observational, cross-sectional study. The data was collected from medical record of all patients who underwent kidney transplantation from January 2014 until December 2018 and the level of creatinine and urine production before and after transplantation was documented. A total of 28 patients were registered and completed the inclusion criteria. The results of the study were tabulated and statistical analysis was performed using SPSS 23.0. The relationship was declared meaningful if p = 0.05 was obtained.


From the analysis of the research that has been done using the Pearson correlation test and hypothesis test Wilcoxon, it was found that there was a relationship between ischemic time and a decrease in creatinine level from r = -0.4489 with a value of p = 0.008. From the analysis of the research, a relationship between ischemic time and urine production was found after transplantation with a value of r = -0.562 and a value of p = 0.002.


The results of this study show a strong correlation between the length of total ischemic time with a decrease in creatinine and urine production which means that the longer ischemic time, the lower the decrease in creatinine levels and the lesser the urine production.

Keywords: Warm ischemic time, Cold ischemic time, Graft function, Kidney transplantation, Urine production, End-Stage Renal Disease.

"Open access will revolutionize 21st century knowledge work and accelerate the diffusion of ideas and evidence that support just in time learning and the evolution of thinking in a number of disciplines."

Daniel Pesut
(Indiana University School of Nursing, USA)

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."

Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."

Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."

Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."

Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."

Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."

Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

J. Ferwerda
(University of Oxford, UK)

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."

Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."

Hubert Wolterbeek
(Delft University of Technology, The Netherlands)

Alessandro Laviano
(Sapienza - University of Rome, Italy)

"Open access journals are very useful for all scientists as they can have quick information in the different fields of science."

Philippe Hernigou
(Paris University, France)

"There are many scientists who can not afford the rather expensive subscriptions to scientific journals. Open access journals offer a good alternative for free access to good quality scientific information."

Fidel Toldrá
(Instituto de Agroquimica y Tecnologia de Alimentos, Spain)

"Open access journals have become a fundamental tool for students, researchers, patients and the general public. Many people from institutions which do not have library or cannot afford to subscribe scientific journals benefit of them on a daily basis. The articles are among the best and cover most scientific areas."

M. Bendandi
(University Clinic of Navarre, Spain)

"These journals provide researchers with a platform for rapid, open access scientific communication. The articles are of high quality and broad scope."
