[Congenital anomalies of the excretory system and their relationship to endemic nephropathy].

The author has studied the congenital anomalies of the urogenital system according to the clinical data of the Nephrology Ward, District Hospital--Vratza, by means of urography, ascending pyelography and reno-vasography. A total of 1960 patients were examined and congenital anomalies of the urogenital system established in 167 (8, 5%). Congenital anomalies of the excretory system, according to the author, are more often met in females (59, 9%) as compated with males (40, 1%) and in left kidney (58, 6%) as compared with the right one (35, 9%). At the same time, the most frequent complication of renal embryopathies was established to be the inflammation process of urinary ducts and kidneys (41, 9%) urinary-calculus disease (19.1%) and endemic nephropathy (8, 9%). The combination of endemic nephropathy and congenital anomalies of the urogenital system is rare (1, 1%) and most likely by chance. The author admits that endemic nephropathy most probably is not causality with the congenital anomalies of the excretory system.
