Acute pyelonephritis or kidney infection: One of the most common renal diseases. Pyelonephritis most commonly results from an ascending infection. The most common infecting organism is Escherichia coli. Others are Proteus, Pseudomonas, Staphylococcus aureus, and Streptococcus faecalis. It primarily affects the interstitial area and the renal pelvis and, less often, the renal tubules. Risk factors can include diagnostic and therapeutic use of instruments, as in catheterization, cystoscopy, or urologic surgery. Inability to empty the bladder, urine stasis (stoppage), urinary obstruction from tumors, strictures, or benign prostatic hypertrophy can also lead to pyelonephritis. Other risk factors includes; sexual activity in women (intercourse increases the risk of bacterial contamination), pregnancy - approx. 5% of pregnant women develop asymptomatic bacteriuria, if left untreated, about 40% develop pyelonephritis. diabetes are also prone to develop pyelonephritis (glycosuria may support bacterial growth in the urine)
Burning during urination
Dysuria (difficulty and or painful urination)
Nocturia (excessive urination at night)
Hematuria (blood in the urine) usually microscopic but possibly gross (visible)
Possible cloudy urine
urine may have a foul smell - fishy odor
Fever of 102 degrees or higher
Chills, shaking chills
Antibiotic therapy for specific infecting organism.
If the infecting organism can't be identified, treatment consist of a broad - spectrum antibiotic.

Renal calculi also called Kidney stones: Kidney stones may form anywhere in the urinary tract but usually develop in the renal pelvis or calyces. Such formation follows precipitation of substances normally dissolved in the urine ( calcium oxalate, calcium phosphate, magnesium ammonium phosphate, or, occasionally, urate or cystine ). The causes are unknown, risk...
