Effect of Per-cutaneous Nephrosotomy Drainage on Radioisotope Imaging of Hydronephrotic Kidneys

• [ Time Frame: ]

Hydronephrosis describes a condition of urine-filled dilation of the collecting system. Normally, urine flows through the urinary tract with minimal or low pressure. If the build-up of excess fluid in the urinary collecting system continues, there will be an increase in pressure and atrophy of renal cortex. If hydronephrosis is left untreated for a long time, renal damage with permanent loss of function occurs

• Procedure: percutaneous nephrostomy
  The percutaneous nephrostomy will be done under sonographic or fluoroscopic guidance. Establishment of intravenous access and antibiotics will be performed half an hour prior to procedure particularly in patients presenting with urinary tract infection. The procedure will be done under local anesthesia but general anesthesia may be used for uncooperative patients. percutaneous nephrostomy will be performed in the prone position, however, in case of relative contraindication to prone position

• : Study group
  Patients will be recruited from out-patient clinics and in-patient sectors of Assiut Urology and Nephrology hospital
