Part I: THE URINARY SYSTEM AND URETERIC STENTS The Urinary System and the Ureter The kidneys produce urine. Normally there are two kidneys situated in the upper part of the abdomen, towards the back. The urine formed in the kidney is carried to the bladder by a fine muscular tube called a ureter. The urinary bladder acts as a reservoir for the urine and when it is full it is emptied via the urethra (water passage).
Late-Gestation and Third Trimester
Mary C. Peavey, Sarah K. Dotters-Katz in Ultrasound of Mouse Fetal Development and Human Correlates, 2021
The urinary system, comprised of the kidneys, ureters, bladder and urethra are responsible for the production and release of urine. Mammalian renal development which includes the differentiation from pronephros, mesonephros, and metanephros; the metanephros persists as the definitive adult kidney, and has a branched collecting duct system and many nephrons. Antenatal hydronephrosis and vesicoureteral reflux (VUR) have been successfully modeled in mice to investigate pathophysiology, along with murine ultrasound techniques. The formation of the heart is very similar in the mouse and the human fetus. Ultrasound has been successfully used to assess the flow and distribution in the mouse fetal circulation in utero and with the additional of color Doppler, anatomy can be further characterized. Measurements of systolic and diastolic cardiac function, as well as distribution of blood flow within the developing fetal body are thus detectable.
Endourology Surgical Anatomy

Endourology has come to the forefront of urologic surgery for the management of various stone and noncalculous conditions. With this, an increasing number of urologists are performing routine and complex endourologic proce-dures, all of which have the potential for significant patient morbidity. Understanding the anatomy and anatomic relationships of the urinary tract is, therefore, vital to mini-mizing complications and maximizing success rates. This chapter describes the basic anatomy of the male and female urinary systems and the relationships of urologic organs to surrounding structures. In addition, common congenital anomalies are discussed, with a focus on implications during endourologic procedures.

ABSTRACT Numerous studies have investigated the association between NQO1 Pro187Ser polymorphism and urinary system cancer risk, but the findings are inconsistent. To derive a more precise estimation of such association, we performed a meta-analysis based on 22 publications encompassing 5,274 cases and 6,459 controls. Overall, significant association was found between NQO1 Pro187Ser polymorphism and urinary system cancer risk. Moreover, stratified analysis observed a statistically significant association for bladder cancer, prostate cancer, renal cell carcinoma, Caucasians, Asians, and hospital-based studies. In summary, this meta-analysis indicated that NQO1 Pro187Ser polymorphism conferred genetic susceptibility to urinary system cancer.

Ochratoxin A contamination of cereals in an area of high incidence of Balkan endemic nephropathy in Bulgaria

In an effort to provide further evidence for the hypothesis that a mycotoxin is involved in the aetiology of Balkan endemic nephropathy and that the latter is associated with the occurrence of urinary system tumours, a survey was made of ochratoxin A contamination of cereal samples from an area of Bulgaria where both endemic nephropathy and urinary system tumours are prevalent and from non‐endemic areas. In all, 130 samples of beans, maize and wheat flour were analysed. Ochratoxin A levels were 16.7% (25–27 μg/kg) in bean samples from the endemic area and 7.1% (25–50 μg/kg) in those from the control areas: in maize samples, the levels were 27.3% (25–35 μg/kg) and 9.0% (10–25 μg/kg), respectively.
