Abstract

Hypothesis / aims of study
Post-operative Urinary retention (POUR)  often  goes undetected and if left untreated may have a deleterious effect on bladder function.Neglected POUR is defined as a partially or untreated  POUR which has lead to a prolonged over-distension of the bladder.The Aim of the study is  to  bring to the fore  Neglected POUR as as a distinct entity and to highlight the effect of neglected POUR on bladder function and the role of  early initiation of Intermittent catheterisation(IC)  to recover bladder function.
Study design, materials and methods
A retrospective study of 24 patients over 3 years  who presented to Urology department   with recurrent  retention of urine or Overflow Incontinence  in the early post operative period. 
Majority  of patients had  a history of post-operative  catheterisation for Post-operative Urinary retention(POUR) and required a 
re-catheterisation .
Trial without catheter(TWOC)  was given after 5 days of secondary catheterisation.
All patients were treated with  Intermittent catheterisation(IC) after a failed secondary catheterisation for a period upto 4 weeks and  IC volume was noted.
Patients were evaluated at 4 weeks and 3 months  with Uroflowmetry and Urodynamic study.
Voiding pattern and Urodynamic  parameters were analysed against :  Time to Primary and Secondary catheterisation , Volume of Urine drained at catheterisation  to see for statistical association.
Results
: 7 /24 (29%) patients had Urodynamic proven  detrusor dysfunction at 4 weeks and required IC. 
: 15 / 24 (71%)had recovery of detrusor function at end of 4 weeks with spontaneous voiding.
: Time to primary catheterisation (>10 hours)had significant correlation(p<0.05) with bladder dysfunction 
: Volume of retained (>1200 ml) was associated with significant Detrusor dysfunction.
: Time to second catheterisation (> 4days ) had significant correlation with bladder dysfunction. 
: Patients with Overflow incontinence after the first TWOC had significantly higher bladder dysfunction than those with recurrent 
   retention of urine.
: Type and duration of anaesthesia did not affect the detrusor dysfunction dysfunction.
: Presence of prior LUTS and DM did not have a significant co-relation  with bladder dysfunction.
 : In 2 patients delayed recovery occurred after 3 months  both of them had primary retention (<20hours )and secondary retention 
    less than 3 days .
Interpretation of results
: Neglected POUR is a consequence of undetected or inadequately treated acute retention
: A primary, temporary neurogenic detrusor dysfunction may ensue 
: Persistent  bladder overdistension causes a rise in intravesical pressure accompanied with a drop in bladder blood flow ,progressive 
  intramural ischemia will eventually lead to nerve and muscle damage damage.
:The main factor for detrusor dysfunction was the prolonged over distension which was overlooked because the patient was not in 
 retention but had overflow incontinence.
:It may be treated with a prolonged Indwelling catheter  or Intermittent catheterisation (IC)
:IC may promote early recovery of bladder function with less incidence of CAUTI.
: Parameters which co-relate with  irreversible Detrusor dysfunction are: Time to first catheterisation( more than 10 hours ) and  
  volume of retention more than 1 litre. 
: The most important predictors of recovery of detrusor function  was  retention less than 9 hours,  retention volumes < than 1200 ml 
  and time to second catheterisation (< 3 days )
Concluding message
: Neglected POUR is a distinct entity because  the sequlae of neglected POUR are different from normal POUR and may be 
 permanent.
: The main factor for detrusor dysfunction was the prolonged over distension which was overlooked because the patient was not in retention but had overflow incontinence.
 :The risk of detrusor dysfunction after neglected POUR is real and significant.
: There is a role of early initiation of IC in promoting recovery of bladder function.
