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.
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.

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 ...
When of gradual onset, symptoms may include loss of bladder control, mild lower abdominal pain, and a weak urine stream. [1] Those with long-term problems are at risk of urinary tract infections. [1] Causes include blockage of the urethra, nerve problems, certain medications, and weak bladder muscles. [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 ...
Physical findings of increased temperature, increased pulse, low blood pressure in the presence of dysuria can indicate systemic infection. Urological obstruction due to stone or tumor can result in findings of hematuria, decreased urination, and bladder spasms. All these physical findings should be looked for carefully while obtaining history.
Enuresis is a repeated inability to control urination. [2] Use of the term is usually limited to describing people old enough to be expected to exercise such control. [3] Involuntary urination is also known as urinary incontinence. [4] The term "enuresis" comes from the Ancient Greek: ἐνούρησις, romanized: enoúrēsis.
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 ...
