Objective:To evaluate influence of acute urological cases (AUC) on course and results of pregnancies. Design: Retrospective clinical study. Setting: 1st Department of Gynaecology and Obstetrics, Department Urology Faculty Hospital, Košice, Slovakia. Methods: 40 pregnant women with AUC aged 15 - 34 years (average 24) which delivered at our Department. Results: The most often occurrence of AUC was in the 2nd and 3rd trimester of pregnancies. 62.5% women were primiparas. The most frequent urological complication was acute pyelonephritis (APNP) - 23 (57%) patients, more often on the right side 4.75: 1. 27 patients (67.5%) had renal colic, more often presents on the right side (6:1). 83% women had infection of urinary tract (IUT). 34 (85%) women were treated by antibiotics or urodesinficiens. 70% pregnancies were closed as intact pregnancies without intrauterine risk of the fetus. Signs of premature labour had 8 patients (20%), hypotrophy of the fetus was evaluated in two patients (5%) and 2 pregnancies were terminated by caesarean section due to intrauterine asphyxia of the fetus.We identified nearly double increase of premature labours in the group of women with AUC in opposition to average in 1998 at Košice district. Risk of newborn early asphyxia syndrome at the 1. minute is important (12.5%). Conclusion: Almost 1/3 pregnancies with AUC have obstetrical complication. Most common incidence of AUC is at the first gravidity, at the right side. AUC require complete obstetrical and urological examination with adequate therapy.We can reduce incidence by careful prenatal care and therapy.
