Introduction:
There are no clear guidelines on the management of Chronic Urinary Retention (CUR). Use of pre-operative urodynamics (UDS) and bladder outflow surgery is variable. The aim of this study was to assess the correlation between pre-operative high residual volume (RV) and successful voiding after transurethral resection of prostate (TURP).
Materials and Methods: A database of TURPs between 2012 and 2018 was accessed to collect data on men with a pre-operative diagnosis of CUR. Successful outcome was defined as freedom from catheter.

Results:
Of the 93 TURPs for CUR, 49 (52.6%) were successful. Mean age of Success vs Failure group was 70 vs 75 years (p<0.05). 14 men in Success vs 16 in Failure group had comorbidities relevant to poor outcomes (p>0.05). Mean RVs in the Success (1.4L, range 0.6-4) and Failure (1.2L, range o.4-3) groups were not significantly different (p=0.07). Outcomes of those with RV=/> 1.5L were not different from those with RV<1.5L (57% catheter-free vs 48%; p=0.41). Of the 58 men with BOO on pre-operative UDS, only 34 (59%) had a successful outcome. Post-operative UDS was not carried out on them. Of the 29 who did not have pre-operative UDS, only 12 (41%) had a successful outcome.

Conclusions:
Outcomes of TURP in men with CUR are not dependent on RVs and co-morbidities, although advanced age can be a factor. Routine use of pre-operative UDS can help in patient selection for surgery. In those with failed surgery, post-operative UDS should be carried out to exclude persistent obstruction.
