Introduction & Objectives:
Kidney stone disease (KSD) and UTI frequently co-exist, often forming a vicious cycle. We wanted to see whether treatment of KSD in these patients leads to an infection-free status post-operatively.

Material & Methods:
Over a 5-year period between 2012-2016, all patients with KSD and recurrent UTIs or pre-operative positive urine culture, who underwent ureteroscopy (URS) for stone disease, were maintained in a prospective database. Data was collated for patient and stone demographics, urine culture and outcomes of URS were analysed retrospectively.

Results:
103 consecutive KSD patients with a history of recurrent UTI (n=22,21%) or positive pre-operative urine culture(n=81,79%) were identified with a male:female ratio of 37:66 and a mean age of 60 years (Table). The mean stone size, operative duration and stone free rate (SFR) was 16.4mm, 51 minutes and 96% respectively. The overall complication rate was 12.6% (7 UTI, 3 sepsis, 3 stent pain).

At first follow-up, the stone and infection free rates (IFR) were 96% and 88%, and this was sustained at 12-months (n=82) with SFR and IFR rates of 88% and 71% respectively.

Conclusions:
Ureteroscopic clearance of kidney stones is an effective strategy to eliminate UTIs in the majority of patients, with a small risk of treatment related infective complications.
