1. clinical feature
Its clinical feature can be vary according to different etiology, location, extent and duration, or completely asymptomatic.
URINARY TRACT OBSTRUCTION
Purpose and demand：
1. master the common reason and treatment of urinary tract obstruction.
2.master the clinical feature、diagnosis 、 differential diagnosis and treament of benign prostatic hyperplasia.
1.Reason and position
Upper urinary tract obstruction is often unilateral, and can also be bilateral, the renal function can be affected quickly; Lower urinary tract obstruction, due to bladder’s compensation and buffering effect, effect on renal function that occurs more slowly, but bilateral.
CT can clear the degree of hydronephrosis and obstruction, judging the renal cortical thickness
Renal function tests, laboratory examination, urodynamic examination
2. Diagnosis
Make sure the reason of hydronephrosis, the site of obstruction, whether combined infection, clear renal function impairment.
B ultrasound: first, most simple, clear the size of hydronephrosis, cortical thickness

2. Diagnosis

2. pathophysiology
above the obstruction,urinary tract dilatation Initial stage ： Ureter thickness Later stage ： Ureter thinning.
Etiological treatment: remove the cause is the best choice.
３. Treatment
Nephrostomy: drainage of urine, improve renal function, select to relieve obstruction
3. be familiar with the pathophysiology change that cause by urinary tract obstruction .
4.be familiar with the treatment of urine
Teaching content：
1.the pathogeny and pathophysiology of urinary tract obstruction.
1.Reason and position
Involve many urinary system diseases. According to urinary obstruction
properties can be divided into mechanical obstruction and dynamic obstruction. According to urinary obstruction part is divided into an upper urinary tract obstruction and lower urinary tract obstruction.

so what's the result that cause by urinary tract obstruction?
Upper urinary tract obstruction can cause hydronephrosis and lower urinary tract obstruction can cause dysuria. Further,it also cause hydronephrosis and injury of renal function. If the bilateral obstruction, which can lead to renal function failure.
2. pathophysiology
Hydronephrosis, renal parenchymal atrophy, thinning, renal pelvis volume increases, eventually become a nonfunction water sac. Lower urinary tract occurrence of obstruction, can make the ureterovesical junction valve loss, leading to urine reflux, hydronephrosis.
2.the pathogeny、pathology、 clinical feature 、 differential diagnosis and treatment of benign prostatic hyperplasia.
3.the diagnosis and treatment of hydronephrosis.
Study independently:the pathogeny and treatment of acute urine retention.
