Objectives To quantify the outcomes of retrograde ureteric stenting in the setting of infected hydronephrosis secondary to ureteric calculi. Patients and Methods Prospective analysis of all patients over a 15-month period admitted with infected obstructed kidneys secondary to ureteric calculi. Inclusion criteria were based on clinical evidence of systemic inflammatory response syndrome (SIRS) and radiological evidence of obstructing ureteric calculi. Outcome measures included success of procedure, admission to intensive care unit (ICU), length of hospital stay, morbidity, and all-cause mortality during hospital admission. Results In all, 52 patients were included. Success of retrograde ureteric stenting was 98%. In all, 17% of patients required an ICU admission, with a post ureteric instrumentation ICU admissions rate of 6%. The mean white cell count and serum creatinine improved significantly after the procedure. Major complication rate included septic shock 6%, but there were no episodes of major haemorrhage and no deaths. Conclusion Retrograde ureteric stenting is safe and effective in infected obstructed kidneys with results comparable to percutaneous nephrostomy tube insertion. Post instrumentation ICU admissions occur in 6% of retrograde stentings.
