[Diagnosis of fetal urinary tract deformity and its early surgical treatment].

From July 1987 to August 1989, ultrasound scan was performed in 419 cases of 24-42-week gestation. The result of antepartum diagnosis showed 12 cases of anomaly (7 males and 5 females). After birth, they were all confirmed by pediatric surgery. Seven infants had hydronephrosis (either bilateral or unilateral), two had nephrocystosis (either unilateral or multiple), two had megaureter, one had megabladder, one had single kidney associated with chronic disease, and eight were operated on. The lowest operative age was nine days, and the average age was 72 days. It shows that The operative indications were: (1) increased excretory rate of RBC and WBC; (2) functional damage of tube of kidney; (3) decreased serum albumin and metabolic acidosis; (4) bacteriuria and pyouria; (5) absence of general complications (6) pyelocalicectasis was at least three times that of the healthy side; (7) obstruction of the low urinary tract and or bladder-rectum fistula. Early surgical management is important for eugenic development of the infants.
