Ultrasound-guided epidural anesthesia and sedation for open transvesical Cohen ureteric reimplantation surgery in 20 consecutive children: a prospective case series and proof-of-concept study

BACKGROUND

Epidural anesthesia is usually combined with general anesthesia (GA) for children undergoing sub-umbilical surgery and GA in children is associated with a potential for respiratory events. Aiming to reduce airway manipulation and the use of GA drugs, we designed a study of transvesical Cohen ureteteric reimplantion under epidural anesthesia in sedated, spontaneously breathing children.

METHODS

We enrolled 20 children (3-83 months, 6.3-25.0 kg) scheduled for open transvesical abdominal surgery with Pfannenstiel incision. Sedation was followed by ultrasound-guided epidural anesthesia. Increases in heart rate by > 15% and or patient movements upon skin incision were rated as block deficiencies. Intubation equipment for advanced airway management was kept on standby. The primary study endpoint was successful blockade, meaning that no sequential airway management was required for the spontaneous breathing patients during surgery. Secondary endpoints included any use of fentanyl/propofol intraoperatively and of postoperative analgesics in the recovery room.

RESULTS

All 20 blocks were successful, with no block deficiencies upon skin incision, no need for sequential airway management, and stable SpO2 levels (97-100%). Surgery took a median of 120.5 minutes (IQR: 89.3-136.5) and included one bolus of fentanyl in one patient 120 minutes into a protracted operation. No more systemic analgesia had to be provided in the recovery room.

CONCLUSIONS

Sedation and epidural anesthesia emerged as a useful alternative to GA from our consecutive case series.

Ischemic priapism in a 12-year old patient associated with coronavirus disease 2019 (COVID-19): a case report

Infection with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has been associated with changes in blood coagulation resulting in increased incidence of venous thromboembolic events and coagulopathy. Moreover, single cases of ischemic priapism have been reported in adult patients with SARS-CoV-2 infection. In this report, we describe the case of ischemic priapism in a 12-year-old child with recent SARS- CoV-2 infection.

Rules and regulations for a pregnant endourologist: the European perspective

Introduction

Working in surgery while pregnant is challenging. Navigating this period safely is of paramount importance. Anecdotal observation suggests that there exists great variation among European nations in regard to maternity leave and radiation safety.

The aim of this article was to gain insight into policy patterns and variations across Europe regarding these issues.

Methods

A series of core question items was distributed to representatives across 12 nations Austria, Belgium, Germany, Greece, Iceland, Italy, Netherlands, Norway, Poland, Republic of Ireland, Spain and the United Kingdom).

Results

The total number of weeks with full pay ranged from as little as 4 weeks in Belgium to 32 and Iceland. All countries included in this study give the option of additional weeks beyond the initial period, however at reduced pay. Some offer unpaid leave beyond this. Only 5/12 countries had a specific policy on when the pregnant surgeon should come off the on-call rota. Only Austria, Italy and Poland stipulate a requirement for the pregnant clinician to be replaced or be completely exempt in cases involving radiation. Only Germany, Iceland, Norway and Poland highlight the need to limit radiation dose in the first trimester. Beyond this, Germany alone provides written guidance for reduction in gown weight and along with Poland, display arguably the most forward-thinking approach to resting.

Conclusion

There is a marked range in maternal leave policies across Europe. There also exists a lack of universal guidance on radiation safety for the pregnant urologist. There is urgent need for this void to be addressed.

The External Genitalia Score (EGS): A European Multicenter Validation Study

CONTEXT

Standardized description of external genitalia is needed in the assessment of children with atypical genitalia.

OBJECTIVES

To validate the External Genitalia Score (EGS), to present reference values for preterm and term babies up to 24 months and correlate obtained scores with anogenital distances (AGDs).

DESIGN, SETTING

A European multicenter (n = 8) validation study was conducted from July 2016 to July 2018.

PATIENTS AND METHODS

EGS is based on the external masculinization score but uses a gradual scale from female to male (range, 0-12) and terminology appropriate for both sexes. The reliability of EGS and AGDs was determined by the interclass correlation coefficient (ICC). Cross-sectional data were obtained in 686 term babies (0-24 months) and 181 preterm babies, and 111 babies with atypical genitalia.

RESULTS

The ICC of EGS in typical and atypical genitalia is excellent and good, respectively. Median EGS (10th to 90th centile) in males < 28 weeks gestation is 10 (8.6-11.5); in males 28-32 weeks 11.5 (9.2-12); in males 33-36 weeks 11.5 (10.5-12) and in full-term males 12 (10.5-12). In all female babies, EGS is 0 (0-0). The mean (SD) lower/upper AGD ratio (AGDl/u) is 0.45 (0.1), with significant difference between AGDl/u in males 0.49 (0.1) and females 0.39 (0.1) and intermediate values in differences of sex development (DSDs) 0.43 (0.1). The AGDl/u correlates with EGS in males with typical genitalia and in atypical genitalia.

CONCLUSIONS

EGS is a reliable and valid tool to describe external genitalia in premature and term babies up to 24 months. EGS correlates with AGDl/u in males. It facilitates standardized assessment, clinical decision-making and multicenter research.

Management of ureteropelvic junction obstruction in children-a roundtable discussion

The investigation, management and follow-up of paediatric ureteropelvic junction obstruction is not standardized. The Young Pediatric Urology Committee of the European Society of Pediatric Urology interviewed five experts in the field on various aspects of management and compared this with published literature.

Midline Incision of a Graft in Staged Hypospadias Repair-Feasible and Durable?

Purpose: In severe hypospadias staged repair is commonly used and it is regarded as feasible, safe, and durable. In this article we want to describe the results of a modification of the staged repair: a midline incision of the graft during the second stage. Materials and Methods: This is a consecutive single team (2 surgeons) retrospective series. Between 2014 and 2017, 250 patients underwent hypospadias repair, among them 35 patients that had primary staged hypospadias surgery with completed first and second stage repair. 24 (68.6%) cases received a preputial skin graft and 11 (31.4%) buccal mucosa graft. Median age at first stage was 1.5 (0.5-22.1) years, mean time between first and second stage operation was 0.72 (0.4-1.76) years. Follow up rate was 100%, mean follow up period was 1.50 (0.4-3.8) years. Results: The total complication rate was 22.9%. In buccal mucosa repair the complication rate was 36.4% and in preputial graft repair the complication rate was 16.7%, respectively. In 23 patients (65.7%) during second stage urethroplasty a midline incision was performed (8 glandular graft, 15 penile graft, 6 at level of urethral opening). Complication rate in non-incised urethroplasty was 8.3%, in incision at glandular level 37.5%, in incision at penile level 13.3% and in incision at urethral opening 16.7%, respectively. Conclusions: Two stage repair is the method of choice in the correction of severe hypospadias. In selected cases a midline incision of the graft is feasible and can be applied if needed. Randomized studies will be needed to evaluate the true benefit of incising the graft.

Fetal magnetic resonance imaging of lymphangiomas

OBJECTIVES

To evaluate the fetal magnetic resonance imaging findings of lymphangiomas.

METHODS

The magnetic resonance scans of eight fetuses with lymphangiomas were evaluated. Magnetic resonance evaluation included: number; size; signal intensities of the lesions; thickness of the septae; configuration of the margins; presence of blood breakdown products; change in size or signal intensity (in four patients with multiple examinations); exact expansion of the lesions to the adjacent anatomical structures; and concomitant pathological findings. Results were compared with postpartum clinical assessment and imaging in seven patients and with autopsy in one patient.

RESULTS

Two retroperitoneal, three thoracic, and three cervical lymphangiomas (diameters between 3.3 and 15.6 cm) were included. All lesions consisted of macrocysts, and additional microcystic parts were found in three lymphangiomas. Blood breakdown products were found in one lesion. Agreement with postpartum imaging was excellent. One patient received intrauterine drainage for chylothorax, and one pregnancy was terminated.

CONCLUSIONS

Fetal lymphangiomas display the same magnetic resonance imaging features as postnatal lymphangiomas. Intrauterine magnetic resonance characterization of lymphangiomas provides the exact delineation, detection of associated and/or concomitant pathologies, and differential diagnosis among other cystic pathologies. Patient management may be altered with respect to the type and/or time of treatment, and with regard to the continuation or termination of pregnancy.
