Modern Surgical Treatments of Urinary Tract Obstruction

Obstructive nephropathy is a term describing the damage to the renal parenchyma that results from the obstruction to the flow of urine anywhere along the urinary system. Long term obstruction causes chronic renal disease. Obstruction coexisting with infection and impaired renal function, when complicated by elevated temperature and leukocytosis that can lead to septic shock, are an absolute indication for urinary diversion such as percutaneous nephrostomy. This particular patient needs emergency diversion. One of the most common indications of nephrostomy placement is ureteric obstruction causing uremia. It is therefore necessary to make the patients fit enough for the designated surgery.
