Anterograde irrigation - assisted ureteroscopic lithotripsy in patients with percutaneous nephrostomy

Int. braz. j. urol; 45 (2), 2019
ABSTRACT In complicated urinary tract infection with ureteral calculi, urinary diversion is inevitable. So, stenting or percutaneous drainage can be an option. In hemodynamically unstable patients, percutaneous drainage is superior to ureteral stenting (1). Once acute infection is controlled, definite tr...
