Background and Objectives: Urinary tract infections (UTIs) are an important cause of perinatal and maternal morbidity and mortality. The aim of this study was to describe and compare the main pregnancy outcomes among pregnant patients with complicated and uncomplicated UTIs; Materials and Methods: This retrospective study included 183 pregnant patients who were evaluated for uncomplicated UTIs and urosepsis in the Urology Department of ‘C.I. Parhon’ University Hospital, and who were followed up at a tertiary maternity hospital—‘Cuza-voda’ from Romania between January 2014 and October 2023. The control group (183 patients) was randomly selected from the patient’s cohort who gave birth in the same time frame at the maternity hospital without urinary pathology. Clinical and paraclinical data were examined. Descriptive statistics and a conditional logistic regression model were used to analyze our data. Results: Our results indicated that patients with urosepsis had increased risk of premature rupture of membranes (aOR: 5.59, 95%CI: 2.02–15.40, p < 0.001) and preterm birth (aOR: 2.47, 95%CI: 1.15–5.33, p = 0.02). We could not demonstrate a statistically significant association between intrauterine growth restriction and pre-eclampsia with the studied urological pathologies. Conclusions: Careful UTI screening during pregnancy is needed for preventing maternal–fetal complications.

Background and Objectives: Minimally invasive procedures, such as double-J ureteric stenting, could be a promising therapeutic alternative to conservative management of obstructive urinary tract pathology. We aimed to evaluate the safety and effectiveness of double-J ureteric stenting in pregnant women with ureterohydronephrosis or urolithiasis, along with their infectious complications, and to assess the pregnancy outcomes of this cohort of patients in comparison with a control group. Materials and Methods: This observational retrospective study included 52 pregnant patients who underwent double-J ureteric stenting for urologic disorders in the Urology Department of ‘C.I. Parhon’ University Hospital, and who were followed up at a tertiary maternity hospital- ‘Cuza-Voda’, Iasi, Romania. The control group (63 patients) was randomly selected from the patient’s cohort who gave birth in the same time frame at the maternity hospital, without urinary pathology. Clinical, sonographic, and laboratory variables were examined. Descriptive statistics, non-parametric tests, and a one-to-one propensity score-matched analysis were used to analyze our data. Results: The univariate analysis indicated a significant statistical difference between the control group and the interventional group regarding maternal age (p = 0.018), previous maternal history of renal colic (p = 0.005) or nephrolithiasis (p = 0.002). After applying the propensity score-matched analysis, cesarean delivery rates (p < 0.001), preterm labour (p = 0.039), premature rupture of membranes (p = 0.026), preterm birth rates (p = 0.002), and post-partum UTI rates (p = 0.012) were significantly different between the control group and the matched treatment group. Ureterohydronephrosis, whether simple (n = 37; 71.2%) or infected (n = 13; 25%), was the main indication for double-J ureteric stenting. Complications such as pain (n = 21; 40.3%), stent migration (n = 3; 5.76%) or encrustation (n = 2; 3.84%), as well as reflux pyelonephritis (n = 2; 3.84%) and gross hematuria (n = 1; 1.92%) were recorded during follow-up. Conclusions: Our results show that double-J stenting is a safe and effective treatment option for pregnant patients with obstructive urological disorders.

Background and Objectives: Acute urologic complications, including bladder and/or ureteric injury, are rare but known events occurring at the time of caesarean section (CS). Delayed or inadequate management is associated with increased morbidity and poor long-term outcomes. We conducted this study to identify the risk factors for urologic injuries at CS in order to inform obstetricians and patients of the risks and allow management planning to mitigate these risks. Materials and Methods: We reviewed all cases of urological injuries that occurred at CS surgeries in a tertiary university centre over a period of four years, from January 2016 to December 2019. To assess the risk factors of urologic injuries, a case-control study of women undergoing caesarean delivery was designed, matched 1:3 to randomly selected women who had an uncomplicated CS. Electronic medical records and operative reports were reviewed for socio-demographic and clinical information. Descriptive and univariate analyses were used to characterize the study population and identify the risk factors for urologic complications. Results: There were 36 patients with urologic complications out of 14,340 CS patients, with an incidence of 0.25%. The patients in the case group were older, had a lower gestational age at time of delivery and their newborns had a lower birth weight. Prior CS was more prevalent among the study group (88.2 vs. 66.7%), as was the incidence of placenta accreta and central praevia. In comparison with the control group, the intraoperative blood loss was higher in the case group, although there was no difference among the two groups regarding the type of surgery (emergency vs. elective), uterine rupture, or other obstetrical indications for CS. Prior CS and caesarean hysterectomy were risk factors for urologic injuries at CS. Conclusions: The major risk factor for urological injuries at the time of CS surgery is prior CS. Among patients with previous CS, those who undergo caesarean hysterectomy for placenta previa central and placenta accreta are at higher risk of surgical haemostasis and complex urologic injuries involving the bladder and the ureters.

Background and Objectives: Urosepsis is a significant cause of maternal and fetal mortality. While certain risk factors for urinary tract infections (UTIs) in pregnant women are well established, those associated with an elevated risk of urosepsis in pregnant women with upper UTIs remain less defined. This study aims to identify factors linked to an increased risk of urosepsis and examine urologic treatment outcomes in such cases. Materials and Methods: We conducted a retrospective analysis on 66 pregnant women diagnosed with urosepsis over a nine-year period. A control group included 164 pregnant women with upper UTIs, excluding urosepsis, admitted during the same timeframe. This study highlights factors potentially contributing to urosepsis risk, including comorbidities like anemia, pregnancy-related hydronephrosis or secondary to reno-ureteral lithiasis, prior UTIs, coexisting urological conditions, and urologic procedures. Outcomes of urologic treatments, hospitalization duration, obstetric transfers due to fetal distress, and complications associated with double-J catheters were analyzed. Results: Pregnant women with urosepsis exhibited a higher prevalence of anemia (69.7% vs. 50.0%, p = 0.006), 2nd–3rd grade hydronephrosis (81.8% vs. 52.8%, p = 0.001), and fever over 38 °C (89.4% vs. 42.1%, p = 0.001). They also had a more intense inflammatory syndrome (leukocyte count 18,191 ± 6414 vs. 14,350 ± 3860/mmc, p = 0.001, and C-reactive protein (CRP) 142.70 ± 83.50 vs. 72.76 ± 66.37 mg/dL, p = 0.001) and higher creatinine levels (0.77 ± 0.81 vs. 0.59 ± 0.22, p = 0.017). On multivariate analysis, factors associated with increased risk for urosepsis were anemia (Odds Ratio (OR) 2.622, 95% CI 1.220–5.634), 2nd–3rd grade hydronephrosis (OR 6.581, 95% CI 2.802–15.460), and fever over 38 °C (OR 11.612, 95% CI 4.804–28.07). Regarding outcomes, the urosepsis group had a higher rate of urological maneuvers (87.9% vs. 36%, p = 0.001), a higher rate of obstetric transfers due to fetal distress (22.7% vs. 1.2%, p = 0.001), and migration of double-J catheters (6.1% vs. 0.6%, p = 0.016), but no maternal fatality was encountered. However, they experienced the same rate of total complications related to double-J catheters (19.69% vs. 12.80%, p > 0.05). The pregnant women in both groups had the infection more frequently on the right kidney, were in the second trimester and were nulliparous. Conclusions: Pregnant women at increased risk for urosepsis include those with anemia, hydronephrosis due to gestational, or reno-ureteral lithiasis, and fever over 38 °C. While the prognosis for pregnant women with urosepsis is generally favorable, urological intervention may not prevent a higher incidence of fetal distress and the need for obstetric transfers compared to pregnant women with uncomplicated upper UTIs.

Background/Objectives: Multidrug-resistant urinary tract infections (MDR UTIs) constitute an important public health problem, especially in pregnant patients. The aim of this retrospective study was to characterize the bacterial spectrum and the profile of microbial resistance in cases of UTIs occurring in pregnant women, as well as their impact on obstetrical and neonatal outcomes. Methods: A total of 371 pregnant patients with UTIs were included in the analysis and were segregated into the following groups based on the type of bacterial resistance to antibiotics: MDR UTIs (70 patients, group 1), UTIs resistant to one class of antibiotics (108 patients, group 2), UTIs resistant to two classes of antibiotics (102 patients, group 3), and sensitive UTIs (91 patients, group 4). We used descriptive statistics for characterizing and comparing the microbial spectrum and the clinical characteristics of the patients. A multinomial logistic regression model for evaluating the relationship between the type of urinary tract infection and adverse obstetric or neonatal outcomes was employed. Results: In the case of MDR UTIs, the bacterial spectrum mainly included Escherichia coli, Enterococcus faecalis, and Klebsiella species. We found almost universal resistance to ampicillin. Our data confirmed an increased risk of preterm birth, premature rupture of membranes, neonatal respiratory distress syndrome, and neonatal intensive care unit admission for patients with MDR infections. Conclusions: The increased incidence of pathogens resistant to commonly used antibiotic classes in pregnancy suggests the need for the development of local and national protocols that adapt therapeutic and prophylactic regimens to clinical realities.

Background/Aim: Placenta percreta is a rare event, but it poses serious problems due to potential hemorrhagic events. We report a particular case of placenta percreta with massive hematuria due to maternal bladder invasion, and describe the surgical protocol performed that resulted in an excellent outcome. Case Report: A 33-year-old patient, at 27th weeks gestational age, presented in the emergency room of the Urology Department with urinary blood clot acute retention, because of massive hematuria from a placenta percreta with bladder invasion. After extracting the clots from the bladder, and coagulation of an area of venous ectasies of the posterior wall, hematuria ceased, but appeared after two days, necessitating again the bladder clots removal and coagulation. A surgical team with gynecologists, urologists, anesthesiologists and a neonatologist was composed, and after bilateral ureteral double J insertion, cesarean section was performed followed by hemostatic hysterectomy and partial cystectomy, bilateral internal iliac artery ligature and repair of the bladder wall. The postoperative evolution was without incidents; the Foley catheter was removed in the 14th postoperative day. Conclusion: In the context of a massive hematuria of a pregnant woman, the urologist must always consider a diagnosis of complicated placenta percreta.
