Effect of silodosin in post operative retention of urine

Shivkaran Gill, Rachhpal Singh, Neeti Rajan Singh


Background: Post-operative urinary retention (POUR) is a common yet potentially serious morbidity with a reported incidence of 3 to 25%. This study aims to evaluate the effect of Silodosin, a super-selective alpha- 1a adrenergic blocking agent, as prophylaxis for post operative urinary retention in patients undergoing various surgical procedures.

Methods: 100 patients were divided into two groups of 50 each. In group 1, patients were given prophylactic silodosin to evaluate its effect in post operative retention of urine and in group 2, patients were not given any medication.

Results: In this study, POUR was diagnosed. POUR was higher in the older age group i.e. more in the age group of 41-60 yrs but in group 1, it was less as compared to group 2. POUR rate in general anaesthesia (GA) patients are less (11.1%) in group 1 as compared to (23.6%) in group 2. POUR rate in spinal anaesthesia (SA) patients are more (21.4%) in group 1 as compared (16.6%) in group 2. The total POUR rate in group 1 was lower (14%) as compared to (22%) in group 2.

Conclusions: In our opinion patients operated under GA, irrespective of gender and type of surgery will benefit from prophylactic silodosin given in pre-operative period for the prevention of POUR and we highly recommend this. Patients who were operated under SA were not benefitted by giving prophylactic silodosin. Probably this is due to use of long acting spinal anesthetic agent in the form of bupivacaine in our patients.
