Abstract

Maternal ureterohydronephrosis (UHN) is a common anatomical change during the evolution of pregnancy, diagnosed especially after the 20th week of pregnancy. The aim of the present study was to evaluate the stages of UHN during pregnancy, depending on the gestational age, and to monitor the symptomatology and the adequate management. A total of 58 pregnant women with UHN, hospitalized in the Constanta County Emergency Hospital, were included in the present study, and had nephrological monitoring using ultrasound examination. Right UHN was observed in all cases and left UHN was observed in only 67.24% of the cases. Regarding the gestational age, right UHN grade III was most commonly seen between 27 and 31 weeks of pregnancy (48.6% of total right UHN grade III from the studied group). The data showed that gestational age and grade of UHN had a highly dependent association in the studied group. The majority of our patients (67.24%) were symptomatic, and the most common complaint on presentation was lumbar pain. According to the visual analog scale (VAS) of the lumbar pain, the group could be distributed as follows: 17.24% with severe pain, 36.21% with moderate pain and 13.79% with mild pain. Eight pregnant women (13.79%) from the present study developed UHN due to passage of a ureteral stone, although the majority of the patients experienced complications with urinary tract infection and acute kidney injury. In addition, 97% of the symptomatic UHN responded to conservatory treatment and only 2 patients (3.45%) with severe symptomatic UHN needed ureteral stent insertion. Data analysis was performed using IBM SPSS Statistics 23. The study highlighted the existence of an association between gestational age and UHN grading.
