Introduction:
Renal and ureteric calculi are a common presentation to urology. Calculi can lead to pain, ureteric obstruction and infection. For the management of stones there are operative and non-operative options in the form of rigid ureteroscopy (RURS) and extracorporeal shockwave lithotripsy (ESWL). Both involve exposure to radiation, which has potentially deleterious health effects, and come with their own limitations. Here we compare time and dose of radiation exposure of RURS and ESWL for ureteric calculi.
Patients and Methods:
Retrospective review of RURS and ESWL for ureteric calculi was conducted at a single site over 3-years. Data on radiation exposure was compiled from the Image Intensifier from theatre and lithotripsy. Differences in the time (seconds) and dose (mGycm2) of radiation exposure between RURS and ESWL were compared using Mann-Whitney U test. Data analysis was conducted using SPSS Version 25.
Results:
131 patients (55 RURS and 76 ESWL) were compiled. Mean radiation exposure time was 67s for RURS and 4s for ESWL. Mean radiation dose was 3214mGycm2 for RURS and 982mGycm2 for ESWL. Time of radiation exposure was significantly lower for ESWL compared with RURS (4±6 vs. 67±56s; P<0.001). Similarly, total radiation dose was significantly lower for ESWL compared with RURS (982±664 vs. 3214±3649mGycm2; P<0.001).
Conclusions:
These data demonstrate that the time and dose of radiation exposure is significantly lower for ESWL compared with RURS. This might have long term health effects on patients undergoing repeat treatments and should be taken into account when considering treatment options on an individual level.
