Rules and regulations for a pregnant endourologist: the European perspective

Occupational Radiation Exposure During Pregnancy: A Survey of Urologists on Perception, Experience, and Practice Patterns

Introduction: The field of urology is predominantly male; however, there has been an increasing number of women in the workforce. Peak reproductive years frequently overlap with residency training and early attending career timelines. Exposure to ionizing radiation is a common occupational hazard in many procedural specialties. The use of radiation, for example, in interventional cardiology and interventional radiology, has shown little adjustments in practice patterns, with no adverse outcomes reported among pregnant physicians in their fields in the setting of appropriate radiation safety measures. The impact of radiation exposure during pregnancy for urologists is largely unknown. Our objective was to determine attitudes and practices of urologists related to radiation exposure and to characterize the experience of urologists who have previously been pregnant. Methods: An anonymous online survey was distributed through relevant society membership bases, which included the Endourological Society and the Society for Women in Urology, and social media. Demographics, practice patterns, and changes to practice patterns were recorded for respondents. Statistical analysis was performed in R studio. Results: There were 384 respondents, 255 of whom identified as women. Of these, 164 had been previously pregnant. Female respondents were younger, completed training more recently, and were more likely to have adjusted their caseload due to radiation concerns compared with their male counterparts. Of women who had been pregnant, few had access to policies for who to notify (19%), policies for safety precautions (22%), custom-fitted lead (35%), and maternity lead (20%). Most women (66%) relied on their own research for guidance on radiation safety during pregnancy, while some (41%) also used information from colleagues or mentors. Forty-six percent of women would have taken greater precautions during pregnancy than they did. Conclusions: Access to the appropriate tools to safely navigate pregnancy is inconsistent among practicing urologists. Evidence-based guidelines are needed to better empower pregnant urologists.

Radiation Exposure Characteristics among Healthcare Workers: Before and After Japan's Ordinance Revision

ABSTRACT

Radioactive materials and ionizing radiation have both medical value and disease risks, necessitating radiation dose measurement and risk reduction strategies. The International Commission on Radiological Protection (ICRP) lowered the lens of the eye exposure limit, leading to Japan's revised "Ionizing Radiation Ordinance." However, the effects on radiation exposure in medical settings and compliance feasibility remain unclear. To examine the impact of the revision to the "Ionizing Radiation Ordinance" and use it for measures to reduce exposure to radiation, a comprehensive analysis was conducted on data collected from Nagasaki University Hospital, Hiroshima University Hospital, and Fukushima Medical University Hospital in 2018, 2020, and April to September 2021. This included information on age, sex, occupation, department, and monthly radiation doses of workers, aiming to assess the impact of the revision to the "Ionizing Radiation Ordinance" on radiation exposure before and after its enforcement. Out of 9,076 cases studied, 7,963 (87.7%) had radiation doses below the measurable limit throughout the year. Only 292 cases (3.2%) exceeded 1 mSv y -1 , with 9 doctors and 2 radiological technologists surpassing 5 mSv y -1 . Radiological technologists showed significantly higher doses compared to doctors, dentists, and nurses (p < 0.01), while male subjects had significantly higher exposure doses than females (p < 0.01). No significant changes in radiation exposure were observed before and after the revision of the Ionizing Radiation Ordinance; however, variations in radiation exposure control were noted, particularly among nurses and radiological technologists, suggesting the impact of the revision and the need for tailored countermeasures to reduce radiation dose in each group.

Radiation exposure in emergency ureteric stenting: A subgroup analysis by operator

Objectives

To review radiation exposure during emergency ureteric stent insertion to identify differences based on operator experience, specialty operator and stone characteristics.

Patients and methods

A retrospective audit over 10 years was performed for patients who underwent emergency stent insertion for urolithiasis with intraoperative fluoroscopy. Outcomes measured included operator experience, radiation exposure (mGy), dose area product (Gy/cm2), fluoroscopy time, stone characteristics and patient BMI. Analysis was performed in IBM SPSS Version 28. p < 0.05 was considered statistically significant.

Results

Four hundred ten patients were identified, with a median age of 57 years, 64.6% male and a median BMI of 30. Urolithiasis was left-sided in 50.8%, with a median size of 7 mm and predominantly proximal (49%) followed by mid (34.5%) and distal (12.1%) location. Median radiation exposure was 12.6 mGy, 2.94 Gy/cm2 and fluoroscopy time 44.5 s, with no significant difference between consultants and registrars. No significant association between radiation exposure for subgroups of stone location, gender, size, laterality or specialty registrar (general surgery vs. urology).

Conclusion

No significant difference in radiation exposure was identified between registrars and consultants or between subspecialty registrars. We suggest formal radiation safety education for all health professionals involved with intra-operative fluoroscopy and personal dosimeters.

Pregnancy and Urology Residency: Towards Equity-centred Practice

For urology to be truly inclusive in the future, an equity-centred approach to pregnancy is required. Conditions for pregnant women and those caring for a newborn must be optimised to achieve this goal. The European Association of Urology could play a role in addressing the key issues and priorities and set an example for national urological associations.

ALARA in Urology: Steps to Minimise Radiation Exposure During All Parts of the Endourological Journey

Purpose of the Review

The global burden of kidney stone disease (KSD) and its management relies on ionising radiation. This includes the diagnosis, treatment and follow-up of KSD patients. The concept ‘As Low As Reasonably Achievable’ (ALARA) developed in response to the radiation risks and the key principles include optimisation, justification and limitation of radiation. This article provides an overview of the topic including background to the risks and steps that can be taken during all stages of endourological management.

Recent Findings

Our review suggests that ionising radiation is an invaluable tool in delineating the anatomy, localising disease, guiding manoeuvres and monitoring treatment in patients with KSD. It therefore plays an integral role in many stages of patient care; preoperatively, intraoperatively and postoperatively.

The reduction of radiation pre- and post-surgical intervention relies on the use of low-radiation CT scan and ultrasound scan. It can also be achieved through various intraoperative techniques or fluoroless techniques in selected patients/procedures, customised to the patients and procedural complexity.

Summary

There are many parts of the patient journey where exposure to radiation can take place. Urologists must be diligent to minimise and mitigate this wherever possible as they too face exposure risks. Implementation of strategies such as teaching programmes, fluoroscopy checklists and judicious use of CT imaging among other things is a step towards improving practice in this area.
