Abstract

Hypothesis / aims of study
Ureteroscopy (URS) effectively treats urinary stones, but post-operative stents can cause discomfort and increase costs. Stentless URS may enhance comfort while maintaining safety. This study compares both approaches for pain, complications, stone-free rates, and satisfaction.

Aim:
• To assess the outcomes of stentless ureteroscopy in treatment of urolithiasis in form of Recurrent ER visit, admission, needs for stent post procedure, AKI, UTI and clearance of stones post op by imaging (US or CT KUB)
• Comparison to conventional ureteroscopy (stent insertion post ureteroscopy) by simple matching:
1- Sex
2- Age
3- Size of stone
4- Stone location
Study design, materials and methods
Of the 31 total stentless ureteroscopies (URS) done, the results demonstrated favorable outcomes with no instances of hospital admission, with only one patient requiring an ER visit. There were no significant elevations in creatinine levels or cases of acute kidney injury (AKI). Among the patients, some retained the stone while others successfully passed it. When compared to conventional ureteroscopy, stentless URS yielded similar results in terms of effectiveness of treatment.
Results
Of the 31 total stentless ureteroscopies (URS) done, the results demonstrated favorable outcomes with no instances of hospital admission, with only one patient requiring an ER visit. There were no significant elevations in creatinine levels or cases of acute kidney injury (AKI). Among the patients, some retained the stone while others successfully passed it. When compared to conventional ureteroscopy, stentless URS yielded similar results in terms of effectiveness of treatment.
Interpretation of results
The stentless group had a significantly lower total cost (24811.3+/-1561.1 SAR) compared to the stent group (33048.4+/-1715.2 SAR) (P-value< 0.0001) . There were no significant differences between the two groups in terms of emergency room visits, hospital admissions, re-stenting, urinary tract infections, and residual stone rates.
Concluding message
Stentless URS is a cost-effective and safe alternative to traditional URS with stent placement for the management of urolithiasis. It can reduce healthcare costs without compromising patient outcomes.
Further large-scale studies are needed to confirm these findings.
