| ureteropelvic obstruction | A blocking or stenosis, usually congenital, at the junction of the renal pelvis and ureter, usually resulting in stasis, pelvocaliectasis, hydronephrosis, or calyceal clubbing. (05 Mar 2000) |

| lacrimal duct obstruction | Interference with the secretion of tears by the lacrimal glands. Obstruction of the lacrimal sac or nasolacrimal duct causing acute or chronic inflammation of the lacrimal sac (dacryocystitis). It is caused also in infants by failure of the nasolacrimal duct to open into the inferior meatus and occurs about the third week of life. In adults occlusion may occur spontaneously or after injury or nasal disease. (12 Dec 1998) |
