Functional Urodynamic Changes in Chronic Kidney Disease Patients and Does Insertion of Urinary Catheter Delay the Need for Kidney Dialysis

Functional Urodynamic Changes in Chronic Kidney Disease Patients and Does Insertion of Urinary Catheter in Chronic Kidney Disease Patients Grade 4 Delay the Need for Kidney Dialysis

The aim of the investigators work is to describe the urodynamic results in the CKD (chronic kidney disease) grade 4 patients and to verify observations that urinary catheter may improve kidney function in those patients.

100 patients with CKD grade 4 will do urodynamic examination.

All patients will be randomized into two groups / the intervention group that will be inserted urinary catheter for 2 weeks and the follow up group. Kidney function will be monitored by creatinin values and the investigators will measure the time to dialysis in the two groups.
