[Diagnosis, therapy and follow-up of infants with urethral valves, treatment concept in the 1st year of life].

Abstract

Within the framework of a joint follow-up we report on the treatment of 57 infants with urethral valves (35 babies from Munich and 22 from Siegen) in the first year of life, studied between 1974 and 1986. In 16 newborn the diagnosis and initiation of treatment was effected during the first four weeks of life (Group I) and in 41 babies during the 2nd to 12th month (Group II). In three cases, diagnosis of suspected urethral valve was made prenatally. Primary management and the concept of further treatment are described. Primary therapy is determined by the general condition after birth, presence of urosepsis and the extent of any existing renal insufficiency. 2 children died, both from Risk Group I. 5 children are in a state of compensated renal insufficiency. In 2 newborn we were compelled to perform supravesical urinary drain and in 3 children a suprapubic drain. Secondary nephrectomy became necessary in 4 children, 3 of whom belonged to Risk Group I. In 23 of 57 children valve resection followed by transurethral drainage was the only therapy. In 22 of 57 children corrective surgery was performed subsequently (neo-implantation, with and without modellage, stenosis of the ureter exit). The article reports on the course in each case.
