phentolamine has been researched along with Hydronephrosis in 4 studies
Phentolamine: A nonselective alpha-adrenergic antagonist. It is used in the treatment of hypertension and hypertensive emergencies, pheochromocytoma, vasospasm of RAYNAUD DISEASE and frostbite, clonidine withdrawal syndrome, impotence, and peripheral vascular disease.
phentolamine : A substituted aniline that is 3-aminophenol in which the hydrogens of the amino group are replaced by 4-methylphenyl and 4,5-dihydro-1H-imidazol-2-ylmethyl groups respectively. An alpha-adrenergic antagonist, it is used for the treatment of hypertension.
Hydronephrosis: Abnormal enlargement or swelling of a KIDNEY due to dilation of the KIDNEY CALICES and the KIDNEY PELVIS. It is often associated with obstruction of the URETER or chronic kidney diseases that prevents normal drainage of urine into the URINARY BLADDER.

| "Results of a pharmacotest with phentolamine show that in hydronephrosis patients the amplitude of contractions of the ureter became 3 times greater, the tonometrical index was 2 times greater, the basic pressure became 2 times less." | 3.67 | [Value of alpha adrenergic blocking agents in the complex treatment of hydronephrosis in children]. ( Abdullaev, KI; Dzhavad-Zade, MD; Frumkin, MV, 1989) |
| "Pretreatment with phentolamine and propranolol enhanced the dilator response of the pre- and postglomerular vessels (except the afferent arterioles near glomeruli and efferent arterioles near welling points) to dopamine (3 X 10(-5) and 1 X 10(-4) M), and abolished the reductions in diameter produced by the high dopamine levels." | 1.27 | Responses of in vivo renal microvessels to dopamine. ( Dussel, R; Fleming, J; Parekh, N; Steinhausen, M; Weis, S, 1986) |
