what is hydronephrosis?
Question:
Answers:
Hydronephrosis is distention and dilation of the renal pelvis, usually caused by obstruction of the free flow of urine from the kidney.
Signs and symptoms
The signs and symptoms of hydronephrosis depends upon whether the obstruction is acute or chronic. Unilateral hydronephrosis may even occur without symptoms.
Blood tests can show elevated creatinine and electrolyte imbalance. Urinalysis may show an elevated pH due to the secondary destruction of nephrons within the affected kidney.
Symptoms that occur regardless of where the obstruction lies include loin or flank pain. An enlarged kidney may be palpable on examination.
Where to obstruction occurs in the lower urinary tract, suprapubic tenderness (with or without a history of bladder outflow obstruction) along with a palpable bladder are strongly suggestive of acute urinary retention, which left untreated is highly likely to cause hydronephrosis.
Upper urinary tract obstruction is characterised by pain in the flank, often radiating to either the abdomen or the groin. Where the obstruction is chronic renal failure may also be present. If the obstruction is complete, an enlarged kidney is often palpable on examination.

Hydronephrosis is dilation of the renal pelvis and calyces. Most commonly this situation is the result of an obsruction of flow to urine more distally (further down) causing urine to back up to the kidney.
