Urinary tract obstruction as a congenital disorder results in oligohydramnios which in turn can lead to the Potter sequence of atypical physical appearance. Pulmonary hypoplasia is by far the main cause of death in the early neonatal period for children with congenital lower urinary tract obstruction.
[1] [2] Diagnosis is typically based on measuring the amount of urine in the bladder after urinating. [1] Treatment is typically with a catheter either through the urethra or lower abdomen. [1] [3] Other treatments may include medication to decrease the size of the prostate, urethral dilation, a urethral stent, or surgery. [1]
Oliguria or hypouresis is the low output of urine specifically more than 80 ml/day but less than 400ml/day. [1] The decreased output of urine may be a sign of dehydration, kidney failure, hypovolemic shock, hyperosmolar hyperglycemic nonketotic syndrome (HHNS), multiple organ dysfunction syndrome, urinary obstruction/urinary retention, diabetic ketoacidosis (DKA), pre-eclampsia, and urinary ...
Without diagnostic evaluation, the cause of underactive bladder is unclear, as there are multiple possible causes. UAB symptoms can accurately reflect impaired bladder emptying due either to DU or obstruction (normal or large storage volumes, elevated post-void residual volume), or can result from a sense of incomplete emptying of a hypersensitive bladder (small storage volumes, normal or ...
Diagnosis of acute failure is often based on a combination of factors such as decreased urine production or increased serum creatinine. [3] Diagnosis of chronic failure is based on a glomerular filtration rate (GFR) of less than 15 or the need for renal replacement therapy. [1] It is also equivalent to stage 5 chronic kidney disease. [1]
Hypouricemia is often benign and not a medical condition, but it is a useful medical sign. It is known occasionally to result in a decreased ability to concentrate urine due to decreased hypertonicity of the renal medulla, and may contribute to hypotension when other risk factors are present.
The diagnosis of neurogenic bladder is made based on a complete history and physical examination and may require imaging and specialized studies. History should include information on the onset, duration, triggers, severity, other medical conditions and medications (including anticholinergics , calcium channel blockers , diuretics, sedatives ...
Large studies of patients have also failed to show any correlation between lower urinary tract symptoms and a specific diagnosis. [11] Also, recently a report of lower urinary tract symptoms even with malignant features in the prostate failed to be associated with prostate cancer after further laboratory investigation of the biopsy.
