Common Urological Problems

Urine

Renal & Ureteral stones Etiology

Mineralization in all biologic systems has a common theme in that the crystals and matrix are intertwined. Urinary stones are no exception; they are polycrystalline aggregates composed of varying amounts of crystalloid and organic matrix.  Theories to explain urinary stone disease are incomplete.  Stone formation requires supersaturated urine.  Supersaturation depends on urinary pH,  ionic… Renal & Ureteral stones Etiology   



Urinary Ions

A. CALCIUM
Calcium is a major ion present in urinary crystals.  Only 50% of plasma calcium is ionized and available for filtration at the glomerulus. Well over 95% of the calcium filtered at the glomerulus is reabsorbed at both the proximal and distal tubules and limited amounts in the collecting tube. Less… Urinary Ions   



Stone Varieties

A. CALCIUM CALCULI
Calcifications can occur and accumulate in the collecting system,  resulting in nephrolithiasis.  Eighty to eighty-five percent of all urinary stones are calcareous.

Calcium nephrolithiasis is most commonly due to elevated urinary calcium, elevated urinary uric acid, elevated urinary oxalate,  or a decreased level of urinary citrate.

Hypercalciuria is… Stone Varieties   



Scientists learn more about how kidneys fail and how new drugs may intervene

Scientists are learning more about how protein gets in the urine when the kidneys begin to fail and how a new drug blocks it.

“We have known for a long time that renal failure comes with protein in your urine, especially in diabetes,” said Dr. David Pollock, renal physiologist at the Medical College of… Scientists learn more about how kidneys fail and how new drugs may intervene   



The Urinary System and How It Works

The urinary system cleans the body of wastes. It gets rid of everything that the body does not need, to maintain balance in the rest of the systems. For instance, your body does not need 16 ounces of meat at dinner. The waste products of that meat will be circulated to your kidneys to… The Urinary System and How It Works   



The Balance Concept - The Urinary System

The kidneys preserve a very delicate balance in the body. They compensate for your food and fluid intake to maintain this balance.

For instance, if you drink a great deal of water, there is a greater volume of urine. If you eat a lot of salt (that bag of potato chips that disappeared during… The Balance Concept  - The Urinary System   



Loyola study debunks common myth that urine is sterile

Researchers have determined that bacteria are present in the bladders of some healthy women, which discredits the common belief that normal urine is sterile. These findings were published in the April issue of the Journal of Clinical Microbiology by researchers at Loyola University Chicago Stritch School of Medicine (SSOM).“Docve been trained to believe that… Loyola study debunks common myth that urine is sterile
