Waiting time for male bladder outflow tract surgery
Data were extracted for all patients that had been admitted to hospital as an emergency admission with a diagnosis of urinary retention (ICD-10 code R33) from 1st January 2014 to 31st December 2018. Only first emergency admissions were included; subsequent emergency admissions with urinary retention for the same patient were excluded. These data were then linked to any subsequent bladder outflow tract procedure (OPCS codes M651, M652, M653, M654, M655, M658, M659) in the 12 months following the emergency admission. Only first procedures were counted for those that had more than one bladder outflow tract procedure in the 12 month period.
