General Information Waste products of metabolism are toxic (CO2, ammonia, etc.) Removal from tissues by blood and lymph Removal from blood by Respiratory system And Urinary system Functions of the Urinary System Elimination of waste products Nitrogenous wastes Toxins Drugs Functions of the Urinary System Regulate homeostasis Water balance Acid-base balance in the blood Electrolytes Blood pressure Organs of the Urinary system Kidneys Ureters Urinary bladder Urethra Kidneys Primary organs of the urinary system Located between the 12th thoracic and 3rd lumbar vertebrae. Right is usually lower due to liver. Held in place by connective tissue [renal fascia] and surrounded by thick layer of adipose [perirenal fat] Each kidney is approx. 3 cm thick, 6 cm wide and 12 cm long Regions of the Kidney Renal cortex: outer region Renal medulla: pyramids and columns Renal pelvis: collecting system Kidneys protected by three connective tissue layers Renal fascia -Attaches to abdominal wall Renal capsule: -Surrounds each kidney -Fibrous sac -Protects from trauma and infection Adipose capsule -Fat cushioning kidney Nephrons Each kidney contains over a million nephrons [functional structure] • Blood enters the nephron from a network that begins with the renal artery. • This artery branches into smaller and smaller vessels and enters each nephron as an afferent arteriole. • The afferent arteriole ends in a specialized capillary called the Glomerulus. • Each kidney has a glomerulus contained in Bowman’s Capsule. • Any cells that are too large to pass into the nephron are returned to the venous blood supply via the efferent arteriole.

The Kidneys (Nephros)
THE KIDNEYS (NEPHROS) Functions 1. Removal of excess water, salts and products of protein metabolism 2. Maintenance of PH 3. Production and release of erythopoietin, which controls blood cell production 4. Synthesis and release of renin to influence blood pressure 5. Production of 1, 25-hydroxycholecalciferol (activated form of vitamin D) for control of calcium metabolism. There are 2 kidneys in the body, one on either side of the median plane. The kidneys are bean-shaped about 10cm long, 5cm wide and weigh about 150g. The kidneys are intra-abdominal extending from T12-L3. The left kidney is about 1cm higher than the right one, owing to the large right lobe of the liver. The kidneys lay retroperitoneally on the posterior abdominal wall against Psoas major muscle. Each kidney is covered by a tough fibrous renal capsule. This is surrounded by fat known as perirenal /perinephric fat. The latter is enclosed in a renal fascia which attaches it firmly to the posterior abdominal wall. However, the renal fascia is flexible enough to allow kidneys shift slightly as the diaphragm moves during respiration. The kidney has • Anterior and posterior surfaces • Medial and lateral borders • Superior and inferior poles The lateral border is convex and lies against psoas major muscle. The medial border is concave. The hilus/hilum is a prominent medial indentation on this border. It’s a point of entry for the renal artery, renal nerves and exit for the renal vein and renal pelvis. From anterior to posterior are the; renal vein, renal artery and renal pelvis. The posterior surface of the superior pole is related to the diaphragm while the anteromedial surface to the suprarenal gland.

Torsion of Appendix of Testis

An case of torsion of the appendix of testis is described in a 10 years old boy. He presented with sudden onset of severe pain in the left testis of 3 days duration. Emergency exploration of the left testis revealed a gangrenous appendix of the left testis. The appendix of the testis was excised and the wound was closed. The patient made a smooth post-operative recovery. KEY WORDS: torsion, appendix testis, exploration, gangrene INTRODUCTION and epididymis were normal.

The Urinary System Dr
The urinary System Dr. Ali Ebneshahidi Functions of the Urinary System • Excretion – removal of waste material from the blood plasma and the disposal of this waste in the urine. • Elimination – removal of waste from other organ systems - from digestive system – undigested food, water, salt, ions, and drugs. + - from respiratory system – CO2,H , water, toxins. - from skin – water, NaCl, nitrogenous wastes (urea , uric acid, ammonia, creatinine). • Water balance -- kidney tubules regulate water reabsorption and urine concentration. • regulation of PH, volume, and composition of body fluids. • production of Erythropoietin for hematopoieseis, and renin for blood pressure regulation. Anatomy of the Urinary System Gross anatomy: • kidneys – a pair of bean – shaped organs located retroperitoneally, responsible for blood filtering and urine formation. • Renal capsule – a layer of fibrous connective tissue covering the kidneys. • Renal cortex – outer region of the kidneys where most nephrons is located. • Renal medulla – inner region of the kidneys where some nephrons is located, also where urine is collected to be excreted outward. • Renal calyx – duct – like sections of renal medulla for collecting urine from nephrons and direct urine into renal pelvis. • Renal pyramid – connective tissues in the renal medulla binding various structures together. • Renal pelvis – central urine collecting area of renal medulla. • Hilum (or hilus) – concave notch of kidneys where renal artery, renal vein, urethra, nerves, and lymphatic vessels converge. • Ureter – a tubule that transport urine (mainly by peristalsis) from the kidney to the urinary bladder. • Urinary bladder – a spherical storage organ that contains up to 400 ml of urine. • Urethra – a tubule that excretes urine out of the urinary bladder to the outside, through the urethral orifice.

Post Mortem Examination of the Urinary System
Post Mortem Examination of the Urinary System System examination Figure 1 Figure 2 Place kidney on a flat surface and apply dorsal pressure with your hand (Figure 1). While applying this dorsal pressure use a sharp knife to cut through the kidney from cortex to renal pelvis and butterfly open the organ. Examine the cortical, medullary, and renal pelvic architecture and determine the consistency of the organ by grasping a 1 cm slice between the index finger and thumb and applying pressure (Figure 2). Figure 3 Using a pair of forceps to hold the capsule, strip it from the cortical surface (Figure 3). In normal circumstances, the capsule should strip fairly easily. In chronic renal lesions, there may be capsular fibrosis with surface adhesions which makes stripping more difficult. Figure 4 Figure 5 Urinary bladder is initially examined in situ to observe any abnormalities on the serosal aspect as well as any evidence of pathology in the ureters (Figure 4). An incision is made through the bladder wall to open the bladder and reveal the mucosal surface for examination, or the bladder is turned inside out through the incision to observe the surface (Figure 5). Renal and Urinary Bladder Non-Lesions Pale kidneys Figure 6 In cat’s kidneys are pale tan or even light cream in colour. Cortical vessels are prominent and lie in grooves in the subcapsular surface (Figure 6). These two features on normal findings in feline species.

Kidney in an Effort to Aid Health Information Management Coding Professionals for ICD-10, the Following Anatomy Tip Is Provided with an Educational Intent
Anatomy Tip Kidney In an effort to aid Health Information Management Coding Professionals for ICD-10, the following anatomy tip is provided with an educational intent. The kidneys are the main part of the urinary system and are a pair of organs; right and left; located in the back of the abdomen. Each kidney is about 4 or 5 inches long. • The kidneys are surrounded by three layers of tissue: • The renal fascia is a thin, outer layer of fibrous connective tissue that surrounds each kidney (and the attached adrenal gland) and fastens it to surrounding structures. • The adipose capsule is a middle layer of adipose (fat) tissue that cushions the kidneys. • The renal capsule is an inner fibrous membrane that prevents the entrance of infections. • There are three major regions inside the kidney: • The renal cortex borders the convex side. • The renal medulla lies adjacent to the renal cortex. It consists of striated, cone-shaped regions called renal pyramids (medullary pyramids), whose peaks, called renal papillae, face inward. The unstriated regions between the renal pyramids are called renal columns. • The renal sinus is a cavity that lies adjacent to the renal medulla. The other side of the renal sinus, bordering the concave surface of the kidney, opens to the outside through the renal hilus. The ureter, nerves, and blood and lymphatic vessels enter the kidney on the concave surface through the renal hilus. The renal sinus houses the renal pelvis, a funnel-shaped structure that merges with the ureter. • All the blood in our bodies passes through the kidneys several times a day.
