Background: Transplantation has revolutionized
treatment of end- stage renal disease (ESRD) by proving
more cost effective than hemodialysis, with a lower
morbidity and improved quality of life.
Objective: To evaluate the development of these
complications in the first month postoperatively and
correlate their development to the type of donation
whether related or unrelated.
Methods: Fifty (50) patients aged (15-62) years, with a
mean age (34.46 ± 12.4 SD) years with (ESRD), who
underwent renal transplantation from September 2000 to
October 2002, were followed-up for one month
postoperatively clinically and by assessment of renal
function tests, sonographic and Doppler examinations.
Ureteral obstruction was considered in those patients who
had allograft dysfunction, ultrasonic evidence of
peritransplant collection, moderate-severe dilatation of
upper urinary tract of transplanted kidney and
postoperative ipsilateral or bilateral leg edema. Ureteral
leakage was considered in those patients who had
persistent drainage of urine with or without allograft
dysfunction. Two patients were excluded from the followup due to death in the first 24-hour postoperatively.
Results: Six (6) patients (12.5% of cases) developed
ureteral obstruction due to peri-ureteral fluid collection. In
five patients the collection decreased and upper urinary
tract dilatation improved gradually, as shown by
ultrasound, on watchful waiting. One patient had surgical
evacuation of a large hematoma. Four (4) patients (8.3%
of cases) developed ureteral leakage. The leakage stopped
in one patient after keeping the urethral catheter for a
longer period. Three patients had surgical exploration due
to persistent urinary leakage. Redo implantation of
allograft ureter was done in two cases.
Development of ureteral complications was compared
with the type of donation (related or unrelated). The
comparison was not statistically significant.
Conclusions: The development of ureteral
complications in not related to the type of donation.
Extravesical ureteral anastamosis with the use of a stent is
less likely to be associated with postoperative ureteral
complications.
Maximum power point tracking (MPPT) is used in photovoltaic (PV) systems to enhance efficiency and maximize the output power of PV module, regardless the variation of temperature, irradiation, and the electrical characteristics of the load. A new MPPT system has been presented in this research, consisting of a synchronous DC-DC step-down Buck converter controlled by an Arduino microcontroller based unit. The MPPT process with Perturb and Observe method is performed with a DC-DC converter circuit to overcome the problem of voltage mismatch between the PV modules and the loads. The proposing system has high efficiency, lower cost and can be easily modified to handle more energy sources. The test results indicate that the u

Generally, statistical methods are used in various fields of science, especially in the research field, in which Statistical analysis is carried out by adopting several techniques, according to the nature of the study and its objectives. One of these techniques is building statistical models, which is done through regression models. This technique is considered one of the most important statistical methods for studying the relationship between a dependent variable, also called (the response variable) and the other variables, called covariate variables. This research describes the estimation of the partial linear regression model, as well as the estimation of the “missing at random” values (MAR). Regarding the

Background:-Osteoarthritis (OA) is the most common form of arthritis and the leading source of physical disability in elderly people. The Prevalence of OA is increasing and will continue to do so as the population gets older. The OA is predominantly managed in primary care centers by primary health care physicians and much can be done to alleviate symptoms from osteoarthritis by combinations of therapeutic options including pharmacological and non-pharmacological treatments.
Objectives of study :- To assess the knowledge, attitude and practice of Iraqi PHCC physicians in Baghdad, AL-Rusafa, regarding the management of osteoarthritis patient, and it's association with sociodemogra
