Eighty-nine patients who underwent ureteroscopic lithotripsy were respectively compared to 22 laparoscopic ureterolithotomy patients on the variables of length of hospital stay (LOS), stone clearance rate, perioperative complications and number of additional procedures. Retrospective analysis showed that operating time was significantly longer for uereterolithotomy (233 min) than for ureteroscopy (101 min) (p < .05). The ureterolithotomy arm also had a longer hospital stay (3.8 days vs 1.6 days, p<0.05). In terms of stone clearance rate the ureteroscopy arm experienced a 60.98% rate vs. 90.91% for ureterolithotomy (p<0.05). In general, the complications rates were higher for the laparoscopy, but the number of additional procedures following treatment were lower than the ureteroscopy arm.
This retrospective study sheds some light on the factors that must be weighed when deciding on appropriate management for stone disease. While ureterolithotomy has advantages in terms of providing a favorable stone clearance rate and decreased follow up procedures, it is a more time intensive and costly procedure and has higher complication rates, most likely due to its generally more invasive nature. This points to the idea that treatment should be individualized based on the patient, and a shared decision-making process should be implemented when determining management strategies.
