[Drug-induced polyuria in the surgical treatment of patients with nephrolithiasis].

Recently, drug polyuria has found wide application in diagnosis and treatment: to detect latent urinary insufficiency, to assess functional performance of the contralateral (unaffected) kidney in nephrolithiasis and calculous pyelonephritis, to stimulate elimination of fragments of the disintegrated concrement, to check up suture impermeability after surgical repair of the urinary tracts, to outline afunctional zone in hydronephrosis. Clinical experience gives grounds for use of saluretics at certain stages of pyelolithotomy for mobilization of intrarenal pelvis and its dissection, removal of the calculus and subsequent suturing of the intrarenal pelvis. Therapeutic polyuria can also facilitate ureterolithotomy.
