تضيق الشريان الكلوي كينونة سريرية هامة. و تكمن أهميته في أنه قد يكون سبباً لفرط ضغط الدم قابل للعلاج، و أنه –عندما يترقى- سبب للقصور الكلوي المزمن. أسباب تضيق الشريان الكلوي عديدة أهمها: التصلب العصيدي و خلل التنسج العضلي الليفي (تشكل أكثر من 59 % من الحالات). تصوير الأوعية بالطرح الرقمي DSA هو المعيار المرجعي في التشخيص الشعاعي لتضيق الشريان الكلوي، و لكنه يحمل خطورة كونه إجراء راض. يُستخدم الإيكو دوبلر في تقييم الشرايين الكلوية، و يتميز بكونه غير راض و غير مكلف.
Renal artery stenosis is an important clinical entity. its importance lies in that it may be a treatable cause of hypertension, and it is -when progress- a cause of chronic renal failure. The causes of renal artery stenosis are numerous, the most common are: atherosclerosis and fibromuscular dysplasia (accounts for more than 95% of cases). Digital Subtraction Angiography (DSA) is the standard reference in the radiologic diagnosis of renal artery stenosis, but it carries the risk of being invasive procedure. Doppler ultrasound is used in the evaluation of the renal arteries, and it has the advantage of being non-invasive and inexpensive.

In this study 500 obese pregnant women and 250 non-obese pregnant women
(Group of Control) were followed up to prove the role of obesity as a high risk
factor on the incidence of (P.I.H.). We found that:
1. There is a considerable increase in the
incidence of (P.I.H.), which was
proportional to the grade of obesity in the main group. The incidence of P.I.H.
was : %15.38 in grade 1, %26.42 in grade 2 and %42.22 in grade 3 of obesity
(Vs. %6.4 in the control group).
2. There is a considerable increase in the incidence of (P.I.H.) among the obese
pregnant women, especially when they are 36-45 years old (%32.39 Vs. %6.45
in control group).
So that it is advisable to screen all obese pregnant women especially when they
are 36-45 years old and consider them as a high risk group for the indicence of
(P.I.H.).
Treatment of the cryptorchid testicle is justified due to the increased risk of
infertility and malignancy as well as the risk of testicular trauma and torsion and psychological stigma on
patients and their parents. Approximately 20% of cryptorchid
testicles are nonpalpable. Many
Radiological methods in addition to surgical exploration have been used to localize the non-palpable testis.
In these cases, the laparoscopic technique is a usefull method for diagnosis and treatment.
The study was performed in 64 children aged 6 months to 5 years had
ventricuLar septal defect. Systolic pressure in the right ventricle and
Pulmonary Hypertension were determined by two ways.
1- From arteriovenous shunt via ventricular septal defe
ct the
correlation ratio of doppler echo cardiographic catheterization
values was %76.
2- From systolic regurgitation via the tricuspid valve the correlation
was %97.
The diagnosis of pleural diseases is one of the frequent clinical problems. Despite a
variety of diagnostic tests are available for evaluating pleural effusions, approximately 15–
20% of pleural effusions remains undiagnosed, In this cases ,a thora
coscopy plays an
important role, it permits the surgeon to visually view and evaluate the entire pleural space
,and to obtain enough accurate biopsies from suspected areas. This study aims to evaluate
the effectivenes of Video Assisted
Thoracoscopic surgery (VATS) in diagnosis of pleural effusions.
Between June 2012 and June 2015 we performed 38diagnostic thorososcopy for
undiagnosed pleural effusions. The histopathologic studies of pleural biopsies result were
as follows : )%60,5 ( malignancies,)%31,6 ( TB And )%7,9 ( nonspecific inflammatory
reaction.
The malignant diseases are: Mesothelioma )%60,9(, Metastases of adenocarcinoma
)%30,4(,Lymphoma )% 8,7(
4 Complications ,with no mortality.
Conclusion: Video Assisted Thoracoscopic Surgery is a safe and accurate diagnostic
procedure for pleural diseases but it also has a very useful role in therapy.(VATS) saves
time, effort and cost, more over it is preferred by the patient as he recovers and returns to
his normal activity rapidly.
Dysfunctional uterine bleeding and postmenopausal bleeding
is one of the most important challenges facing gynecologists.
The results of our study showed the Pipelle not to be as accurate as
the standard dilatation and curettage especially in postm
enopausal women
after measuring the endometrial lining, we related this to the technics we
used in reusing the Pipelle itself which is made for single use, and to
possibly the bias of the pathologist who read the slides.
