Abstract

Abstract: Background: The difficulty in access to the ureter during stone removal surgery enhances the chances of redo-surgery, DJ stenting, and associated complications, this failure leads to mistrust in the doctor-patient relationship.
Objective: This study aims to provide a comprehensive evaluation of the incidence & management of narrow ureters after failure to negotiate retrograde access of rigid or flexible Ureteroscope (6/7.5 Fr ).
Materials and Methods: This is a Prospective, cross-sectional study, conducted at the urology department of Tabba Kidney Institute, from June 2022 to June 2023. The minimum required sample size was 250. Patients aged between > 18 to <60 diagnosed with Unilateral and bilateral ureteric stones and hydronephrosis without ureteric stone obstruction were included in the study. SPSS 22 was used to analyze the data, the chi-square test was applied, with p-value <0.05 as significant.
Result: The overall mean age of the study population was estimated as 40.71 ± 12 years, while gender distribution indicated 138 (55.2%) male and 112 (44.8%) female patients. Group distribution identified 172 (68.8%) patients with negotiable ureter (Group A), while 78 (31.2%) with non-negotiable ureter (Group B).
Conclusion: We conclude that in our population there is a higher incidence of narrow ureters, as compared to other studies which are not accessible even using the same dilatation technique, so it is safe to counsel the patients pre-operatively about the possibility of the narrow ureter and need for pre-stenting. Tabba Ureter Accessibility (TUA) score can be used as a tool to predict the possibility of a narrow ureter.
